Ok I tried reading until I have blurry eyes trying to readjust after so much reading and a headache. Currently I have an 01 B5 A4 1.8tqm stage 2 with stage 3 min 450 HP in the future. So anyway I have a 2000 B5 S4 roller shell so here's my q. I'm thinking of doing the Touareg/Cayenne BBK 6piston set-up. The wheels I would get would be 19" peelers. In layman's terms what would I need for this set-up on my A4? Is it possible to keep the stock A4 suspension and purchase an adaptor? Looking fwd to responses so I can start putting together this project.

Also would this be considered overkill for a stage 2? Also what size wheels would the 6piston clear?

Also I would get a set of Michelin PSS tires. No intention of tracking at the moment, but I do want to try dragging a few times out the year dragging and taking iton a road course several times more than dragging.

Option 1: Source hardware for the 1.8T (http://www.apikol.com/index.php/products/braking/brake-brackets/b5-a4-touareg-cayenne-17z-caliper-brackets.html)

Option 2: Swap in the B5 S4 uprights/axles and use the mounting hardware sold by some guy in the classified section (http://www.audizine.com/forum/classifieds.php?p[mshow]=listing&p[id]=brembo-17z-18z-mounting-hardware-116098)

All other info after that is in the link below.

Not sure I'm understanding your question.

You can swap uprights from the S4 shell onto the A4 and you wont need brackets. If you decide to keep the A4 uprights you'll need adapters. Apikol sells those.

I'm "stock" with 993tt calipers and I don't think it's overkill.

Keep in mind the added unsprung weight from the larger rotors (unless you go with two piece rotors).



Edit:

overkill. why not just do a8 fronts? thats plenty stoping power without the extra weight

The Cayennes are cheap and light. Overkill is a good thing IMO.

Easiest way is to swap in your S4 uprights.

overkill ia not good. you wont have any braking power in the rears. theres more to BBK than just slapping the biggest brakes on that you can find

Sorry, I thought you meant overkill in the sense of having better brakes than are necessary.

The bias of Cayenne calipers is fine on the B5 S4. If the A4 has different rear brakes (Im not too familiar with the B5 A4), then I'd consider upgrading the rear to S4 brakes and possibly the 300mm rear rotor while you're at it.

yea, the rears on our cars are smaller. tbrowing BBK on the front and nothing to the rear will mess with the bias. the rears will be doing less work and can actually increase your braking distance. yes I said *increase braking distance by putting a BBK in tbe front. anyways, tires will always be the limiting factor. good set of tires should be purchased before you even ever touch the brakes

Also what size wheels would the 6piston clear?

The 18zs fit some 17s. I thinks its more of spoke clearance over barrel clearance. My 18z on 18 v710 fit with roughly 10mm clearance on spokes more on the barrell. (Rough estimate)

+1 on upgrading rears. With stock a4 rears and 18z front (hps rear, ebc yellow front) the abs tends to kick in (on tires a8 couldn't lock up). But even with stock rears, 18z still work much better than the a8 (or stock). I mean, the brakes still actually work after a couple high speed stops lol.

I havent installed the 300mm rears so not sure how much better they are.

Also get the ebc yellow pads, much much better than hawk hps (but not apples to apples comparison). Hated the hps, I liked stock better.

GrapeBandit
07-20-2014, 06:04 PM
theres no way in hell that 18z fronts with stock a4 rears stop better than a8 fronts and stock a4 rears. scientifically impossible because the bias will be off and the stock rears will be doing even less work with the 18z fronts.

Yea I was wondering about the rears. Either my eyes were flipping me or it is a scam (tho it might not be an easy bolt on) some cayenne rears for $40 for the pair. Well in any event I might as well go ahead and do the S4 rear. Dunno how hard a swap that would be.

Thats a good deal. They usually go for $100+ per pair. My friend and I are in the process of finishing a bracket for the Cayenne rear (for B5 S4, B6, B7, C5). I assume the b5 A4 rear upright is the same as S4?

One stop I'd agree. Multiple stops, a8s are gone. Bad brake bias will always be better than no brakes.

But even without heatsoak, the 18z+ebc yellow felt a lot more confident. The a8+hps simply lacked stopping power. It couldn't even lockup my tires even with me stomping on the pedal. Federal rsr 140threadwear.

Personal experience. Using the same old fluid (motul). Only diff was braided brake lines.

GrapeBandit
07-21-2014, 05:55 AM
^just one stop? lets be realistic here. maybe multiple high spped braking a track or something, but not after just one stop. when you say tje a8+hps couldn't even lock up your tires, how fast are you talking about?

ricekikr
07-21-2014, 06:12 AM
I didnt say after the 1st stop a8s are gone, i said "multiple stops a8s are gone". What I meant is one stop the a8s are good but after every stop a8 tends to fade quickly. Which is exactly the reason to get bbk (not shorter stopping distance but less fade).

Speed: whatever 3rd gear 8000rpm is. Wot cruise stop tune wot cruise stop tune wot cruise stop tune. Cruise = 3min

Even in highway runs a8 fades but in the same exact run, stoptechs (also b5 quattro) didn't fade.

Sorry op. Back to topic.

ricekikr
07-21-2014, 06:23 AM
Lockup anyspeed: I noticed a8 would only let abs kick in the very first half second with me stomping on the pedal. The 18z could make abs kick in the whole time with medium high pressure. Again this is without the rear 300mm installed so could possibly be the reason.

Pads are also different. But comparing 18z+yellow vs a8+hps. Imho 18z+yellow wins in my type of driving.

In normal daily driving stock would do just fine.

You can't bolt up rear Cayenne/Touareg brakes to your B5. They won't bolt up, AND you won't have an e-brake.

The OEM bolt-up options which retain a working e-brake are:

Stock: 245mm
B5 S4: 256mm vented
C5 4.2: 269mm vented

Then you have other options which require aftermarket adapters/brackets and such.

Seerlah
07-21-2014, 04:30 PM
Another option. Saved this in a folder with other crap in the PM system.

Upgraded rears with 255x10mm A6 2002 3.0L rotors (StopTech cross-drilled), and A4 B6 3.0L rear caliper carrier (8E0-615-425G).

Also wanted to add that I was playing around on Bear Mountain on my way to work one day. At the end I caught brake fade and almost rear ended a bus. It was incredibly scary, to say the least. So yeah, the A8 upgrade is def nice for DD, but not for spirited driving. You need brake ducts or something or something of the sort, or else things can end in disaster. I know from personal experience.

Said video: https://docs.google.com/file/d/0B86if9r_HdHjR3BVdE9mQzVhZTA/edit

At the end, me downshifting and switching lanes is what saved me from rear ending the bus. Hear me go, "Phew" after settling behind the sedan (natural reaction).

i think all you guys are exaggerating. now mind you, i used to have stock brakes on my other b5, a 2.0 gt35r build with 19" wheels and trust me, i used to beat the fuk out of that car every god damn day like clock work. 160 on the turnpike and the parkway, whipping around town, and never had any issues. the car used to stop on a dime. either i had a freak braking system in that car, or it was the sticky yokohama's i was rocking. the stock braking system on the b5's were near the top of the list when it comes to cars from 2001. i think it was about 117 feet or less from 60-0

I was on a mountain. Most experience from others are on the track where constant braking is necessary. In my case, they were used hard. I still have the A8 setup on my car (Motul 5.1 fluis, Goodridge/ST lines, Tyrol pin kit, and used to run Hawk HPS pads. Autozone cheapos on there now till I throw my BBK on), but have ST40s I'm too lazy on stripping the paint from and throwing on my car. Anyways, onyl time it ever happened. And only time because it taught me a valuable lesson.

Can you elaborate? There was a V8 C5 at my Pick-n-Pull. I had most of the rear brakes off, but I thought they didn't fit.

Certainly - the "W8 rear brake upgrade" is pretty simple. Basically just B5 S4 calipers with a different OEM carrier to use 269mm D2 A8 rear rotors instead of 256mm B5 S4 rotors.

Carriers can come from C5 A6 4.2 quattro, D2 A8 quattro or VW B5.5 Passat 4 Motion with 4.0 W8 engine. (C5 Allroad 4.2 has a different part number carrier (http://www.ecstuning.com/Audi-All_Road--4.2L/Braking/Caliper/Rear/ES366753/). It looks similar, but is not yet confirmed.)

Calipers can come from: B5 S4, C5 A6 4.2, Allroad 4.2 or Passat W8. (A very slightly different version of these "C43" calipers can be sourced from the D2 A8, but the e-brake cable mechanism is oriented much differently for that model and it would not be possible to hook up the B5 e-brake cables without a bit of fabrication.)

Note that there are multiple sources for calipers and carriers, but only 2 sources that have both together - the C5 A6 4.2 and Passat W8.

Rotors must come from a D2 A8 with 269mm rears.

You will need the lines that go with the calipers as the A4 lines will not hook up. (Flare fitting on A4 vs banjo fitting).

And DIY time: http://www.audiworld.com/tech/wheel1.shtml

07-22-2014, 10:43 AM
Just to clarify, do the brake lines need to come from a a6 4.2 and/or s4 and/or D2 a8? thats the last thing thats not 100% clear to me. Logic tells me as long as the match the car the calipers came from it should be ok...?

walky_talky20
07-22-2014, 11:20 AM
Brake lines basically need to come from the car the caliper came from (but junkyards just cut the rubber lines, so don't expect to get them. Even if you plead.)

B5 S4 caliper uses a flare fitting so you can retain your A4 lines.
A6 4.2, Allroad 4.2, and Passat W8 use a banjo fitting at the caliper end. So you need to use the appropriate lines for that.

I used stainless A6 4.2 lines from ECS.

According to Apikol 300mm kit, its works with both c5 a6 4.2 and the allroad... and the s4 brakes for b5 a4 fitment so It should work then..right?

EDIT: Just checked ECS and the Allroad 4.2L AND A6 4.8L share the same 269x22 rotors. so, same rotors, same caliper, I bet the carrier is the same ( I hope, I just ordered some[wrench])

The Allroad part has a different number than what I am using on my B5. But based on the ECS photos, it looks the same to me. I guess you will find out for us. It's nice you got them on sale. Still a lot of money. You can get these used in the junkyard: calipers and carriers for $35 per side, with a 6-month warranty.

Yeah, I got the calipers with carriers on ebay. Not $35 each, but the junkyeard around me havent had an allroad or v8 a6 in for years, no reason to hold out.

I cross-referenced everything and it seems it should be ok. Even the part # is the same aside from the beginning which designates what model the car is usually.

Apikol and 034 advertises the 300mm kit for both ... so id be surprised if it didnt work. My logic being based on the Calipers/rotors being the exact same. the only thing would be an issue is the clearance with the rear control arm clearance

walky_talky20
07-23-2014, 11:25 AM

Yeah. I'm wondering about that. There is some grinding that is needed to fit the carrier to the B5. Perhaps the Allroad carrier is factory clearanced there or something. That would be nice.

And the part number prefix is important. That is the "debut" chassis for the part. So if the part is unchanged for a new chassis, it will retain the original prefix. Like AWM front wheel hubs carrying the 4A0 prefix, because the hub hasn't changed since the '91 C4 100. In general, if the part number is different, *something* is different about the part.

Example:
06B-905-115-E (http://www.ecstuning.com/ES1551/)
06E-905-115-E (http://www.ecstuning.com/ES281014/)

One of those will fit an AEB valve cover. One of them will not.

Whoever you talked to at ECS is giving incorrect informations. ECS themselves list 2 different rotors for the A6 4.2 and Allroad 4.2:
A6 4.2 rotor: http://www.ecstuning.com/Search/SiteSearch/4B3_615_601/ES252451/
Allroad 4.2 rotor: http://www.ecstuning.com/Audi-All_Road--4.2L/Braking/Rotors/Rear/ES263555/

And those parts don't cross. So unless that geomet rotor is *actual magic*, it can't fit both cars. So I did some digging to see if any Allroad 4.2 owners had problems after buying those fancy A6 4.2 Geomet rotors. Behold, a token upset Allroad owner - burned by the ECS magical rotor:


The tech that did the install noticed that the offset was incorrect on the rotors I supplied. It turns out that I used a link on Google to look for geomet coated rotors and the link was incorrect. It stated it would take you to Allroad drilled and slotted rotors for the 4.2 and it went to a link for S6 rear rotors that only showed a description of "269x22".

Emailed the guys at ECS and supplied all the links involved and the brake conversion I was doing to the 2.7 6SP Allroad. It turns out they don't have any geomet drilled and slotted rotors for the [Allroad] 4.2. ...asked for a refund if they didn't have any 4.2 Allroad geomet rotors...ECS gladly took back the rear S6 geomet rotors with the incorrect offset AND provided a shipping label for paying the post.

Bravo Sir! I kinda wish I saw that thread before ordering the allroad 4.2l calipers/carriers, but it looks like they'll be aluminum so thats a plus! I want to email Apikol about the 300mm kit since it cross fits allroad 4.2l, c5 a6 4.2l, b5 s4, c5 s6....

Rodger, I'm wondering if maybe you can get it to work with those Allroad carriers if you use a different rotor. It seems there are 3 different 269x22 rotors: A8, A6, and Allroad. Maybe one of those is the special sauce.

Stock booster, stock master, stock ABS sensor with washers and S4 uprights is all that's needed for 18z calipers to fit on B5 A4. (And ss lines of course)??


axles (I keep forgetting which axle works)

s4 uprights (need to be grinded for clearance)
*you'll need new suspension arms if you get the aluminum uprights.

**it might be cheaper to get the apikol cayenne brackets for an a4 instead of buying arms and uprights. Double check application as this isn't widely used.

Calipers (try to get 18z, my theory is the smaller pistons will work better with the stock master. I got mine cheaper than what most 17zs go for, but usually they cost more)

Rotors (diff for 18z and 17z. Ebay lotsa choices, but all are vented wrong except for the 2pc ones)
*Needs some machine shop work. Some have gotten away with flapper disc/drill. Depends on 17z or 18z on what has to done.
(Ml55 rotors for the 18z.)

Rs4 lines (stoptech was cheapest, amazon iirc cheaper than no name)

Bolt kit (cheapest available in classifieds here or vortex same for both 18z and 17z or can be pieced together cheaper)

Pads (get 17z for any caliper unless going with 350mm 2pc 18z rotor. Some used 18z pads with some grinding)

You might also need new seals depending on the conditon of the calipers.

Wheels. 17z/18z are wide. Will not fit some rims. (More off spoke clearance issue)

Hopefully. THe local pick n pull scrapped the a8 today FML. Had it all planned out and everything[headbang]

The only think Im worried about is the clearance to the Control arm. If it clears, Ill just get the allroad rotors and call it a day. I should probably just start a new thread at this point [:p]

Well Well Well... So after reaserching a LOT more, I saw a few ppl who did the v8 swap ontheir allroads without too much issue using "v8 calipers/carriers"

After studying the differences between the carriers, I found that they are all about the same, except the Control arms DO NOT need grinding! the back of the caliper carriers is basically flat with no protrusions.

They still need to be spaced with the 1-2 washers as usual, but they clear the A8 Rotors

Mockup...Still not tightened down with washers

Heres a close-up of the control arm clearance.

There is some grinding that is needed to fit the carrier to the B5. Perhaps the Allroad carrier is factory clearanced there or something. That would be nice.


And Bam.

Who would have thought.

yeah, went from unlucky to lucky that fast. Not only that, cross referenced a few part #s and these use the EXACT SAME pads as 20th/337/r32/gli MKIV VW calipers. Lucky me I have a good used set just sitting here!

Ordering some $50 a8 rotors off of ECS, and gonna pick/pull some oem lines (also same size as MKIv calipers I believe) and gonna be all in at about $250![race]


EDIT: the allroad carriers dont seem to fit. Once Bolted down, the rotors rub the carriers, and dont even spin. Im gonna try grinding them down, but looks like ill need proper carriers. Rotors checked out to 269mm so im Guessing the mounting point is just a hair or 2 closer to the hub. hence the different # and not being able to swap components.

So I tried and tried, but gave up since I couldnt grind enough down. So I ordered some 4.2l brackets. Used the box for reference but its clear that the allroad (red) brackets are too short.

Update: brakes are bolted on and wow. Night and day difference.
