cayenne brake upgrade ???? what rotors????

[bergtho]

So I'm confused.

I ordered lines, went with the StopTech RS4 950.33005. They came and they don't appear to be the correct style, however, they are the same ones pictured at Achtuning and the same part number listed from StopTech itself.

They look like this...


But from what I've gathered they should look like this...


That one comes up under kit 950.33006.


I'm rather confused.

When fitting the 18z caliper it uses the Stoptech 950.33006 brake lines.

17z caliper uses Stoptech 950.33006 brake lines also.

[Greedo]

I dug through this thread a little more and it seems like you can run either/or on both the 17z and 18z.

I have the 18z, so to confirm; will I be able to run the 950.33005 on the 18z?

[mholme]

Some kits use flare fittings, some use banjo. I run flare lines on my 18Z set up. As long they are for front calipers, they will work.

[Greedo]

Appreciate the info. Glad to know I can run what I ordered.

[bergtho]

Good to know that both the StopTech 950.33006 and StopTech 950.33005 lines work with both the 17z and 18z calipers.

Does one model of these brake lines, either banjo or flare, have an advantage, such as being longer to allow for more suspension travel?

You can get 034s. They are quite long.

18Z or 17Z and which rotors?

[Greedo]

18z with ML55 Zimmermans.

Looks great!

Anyone stripped the bleeder on the Brembo 17Z or 18Zs? It seems to be common with Brembos on other cars and has been fixed. Has anyone had this problems with these and fixed them?

[Austonwerner4]

Would the 330mm rear cayenne brakes along with the 17z mess up the braking bias.

[coolgraymemo]

Yes

The cayenne rear calipers do not have a parking brake either.

Seems people are using a viper brake for that

[udcc11]

If any of you have the problem of a stripped bleeder they make a kit to fix it. This one used 1/8" pipe threads and you have to cut the tap as you go.

So I have a random issue/question.

I installed the brakes a few weeks ago and have put literally 15 miles on them. That night I noticed a weird noise that sounds like that of a cricket; at the time I didn't think it had anything to do with the brakes as I did two axle rebuilds the same night.

Tonight I took the car to my buddy's shop so we could take a look. I noticed that under hard braking the noise stops, under moderate braking its more faint in sound, but under no braking it's consistent (and annoying). The noise is only coming from the passenger side only.

We looked and one of the mounting bolts (caliper to spindle) was just lightly touching the rotor so I added a washer. That has not solved my problem. The only other difference I could find was the retainer clip was flipped 180 degrees in comparison to the other side.

I also have a vibration which I assumed was due to not enough torque on the axle to transmission bolts, but I checked and they won't get any tighter.

I'm at a loss for the noise and vibration. I am running ML55 rotors and they seem properly bored to accommodate the hub. There's no play in the caliper (solid and no movement or slop), the pads are even contact to the rotor on both sides, etc.

Any thoughts?

[s vier]

Could a pad be slipping slightly on first contact? Like it is moving a fraction of an inch until it re-seats into the notches? Anti squeak applied?

[Austonwerner4]

I've got a set of 18z silver Porsche and 17z calipers for sale. Check the classifieds.

I have the 18zs up front along with a 300mm rotor in the back with the stock caliper.. What can be done to tighten up the brake pedal? It's got a good amount of moosh before they bite. They've been bleeded by a buddy of mine who is a VW tech using their super dooper equipment, so there is definitely no air in the lines. Just wondering if because the stock system obviously wasn't designed to run the real big caliper up front if something has to be done to make it feel more natural.

Bigger master cylinder. How many miles on the setup?

Ah gotcha.. Has anyone changed that up on the B5 yet and noticed a difference? I have maybe 20k on the fronts, 3k on the rear. The problem has been there since going with the bigger fronts though for sure.

Running the full ABS test cycle in VCDS helps a lot. After a few months of normal driving, the car starts to feel like the rears grab earlier than the fronts, and the pedal has more travel overall.

I run the test every 3 months and it tightens up the pedal and produces more front end bite. 17z fronts, B6/7 300mm with 034 caliper spacer rears.

Good to know thanks

A few pics of my 18z's that I recently put on. Love them.

[zatch_303]

looks fantastic

[S4 00 2.7]

Nice!

[01nogaro]

^ thanks guys, here's another

[uponone nogaro]

nice

[dcc236]

Yellow calipers, BBS CH's & Noggy - Just beautiful!

[udcc11]

I like the black crossovers. Should of done that.

[PinoyS4]

Beautiful! Waiting for my yellow calipers to arrive from the shop tomorrow also. Ended up going with the giro discs for rotors. Ill take pics when it's all together

Where did you get yours done?

Where did you get yours done?

Just got them painted and not powder coated. Some shop that does all our powder coating on our customers wheels called "wheel techniques"

Wasn't there someone that said they were using B6/B7 rotors with 18Z calipers? Is that even possible? I have 17z calipers with v70r rotors, 18z would be nice for the better pad choices.

18Z pads fit perfectly on V70R Rotors/17Z Calipers. OD and ID...... unless Centric sent me the wrong pads.

[udcc11]

I'm running 17Z pads in my 18Z calipers with the Mercedes rotor. Fits on there perfect.
