B5 S4 caliper rebuilt and paint (many many pics inside!)

[davidlizard]

Hi guy,

Last fall, I bought a pair of B5 S4 caliper. I've had a good deal and pay only 50$ for the pair. Because I like things to be well done and dont want my car to look like crap, I decided to make those calipers looks better!


This is how they were. Dirty, scratched,little rusted, but in a good mechanical shape.



I've made every pieces apart and sandblast each pieces and then spray a coat of zinc primer (green)

The next picture shows that I buffed polished the appearant part of the caliper to make it look smoot and sharp in the wheel. I've eliminated all the rough surface and the casting process trace.

After the sand blast, that was time for paint job. At first I've used zinc primer because there was a couple of weeks between the sandblast and the final paint. Here are all the pieces ready for PPG epoxy primer...




Beside the paint job I've also had to brush the stainless hardware to make it clean, replace some screws, bleeders and rivets...

The final result is obtained by black basecoat (PPG) and 4 layers of clear coat (PPG)



The green parts has been masked because I dont wanted it to be painted because of their mechanical importance. I dont want my brake pads to sit on paint and Ii dont wanted paint in joints...

I can't wait for the spring to come and install those calipers whit new pads, new slotted rotors whit my immaculate USP summer wheels!!!

Really cool, good job with that.

[absolutegtr]

wow. magnificent job!

I bought caliper paint for my S4 brakes, and it initially came out great (not as nice as your though).....now they are chipped and flaking

I need to find a cheap set and this time powedercoat them

[FutureStage1]

Damn impressive... Nice job.

It's not recommended to powdercoat the aluminum part, go ahead with the two iron parts but do not powdercoat the aluminum part!!! Many thread on this subject and a friend of mine who is mechanical engineer confirm that aluminum will loos important property at high heat...That the reason BBK are not powdercoated...

Nice job chief ! They look very good. I'm doing to cheapo way (spray can LOL):



Are you going with white rings decals?

Are you going with white rings decals?[/QUOTE]

[b5s4tt]

[ApexIt]

Man do I wish I could find a set of B5S4 brakes.....

[El_Chapusca]

Wow great job. BUt why blk

[davidlizard]

Wow great job. BUt why blk

my car is black and I think this calipers whit his gloss paint will be clean and subtle as audi do on RS and I think vivid colors are better on BBK...

[Ultra B6]

damn looks like i better get to work on my set... to bad it wont come out as good...


GREAT job man they look amazing.. cant wait to see what they look like behind wheels

[Matt C]

Whoa...and I thought that I was anal retentive :) They look amazing. I wish that I did that to my B7 calipers. Excellent work man! You should offer that as a service.

[sambrody44]

Really great job. They look better then new.

[davidlizard]

thank you everybody!

[a2gtinut]

looks nice but you used wrong paint- not chemical resistant.
POR15 makes nice stuff.

[davidlizard]

thank you and...Urethane and epoxy primer are 2 component paint that is highly resistant and IMO calipers are not exposed to chemicals more than the body of the car...

[B6JoeS4]

do you paint for a living?

[davidlizard]

do you paint for a living?

???

[Blake260]

that looks fan-fucking-tastic....I thought mine came out nice with the black paint and the S4 decal, but the look like poop compared to yours.

[blmlozz]

exactly what kind of ppg paint did you use?

[kwik_shift]

Nice, now I see why patience pays off. Post some pics on the car, which I know may take some time.

[davidlizard]

Dont have product numbers with me but it was" 2 component epoxy primer, black base coat, 2 component Urethane clear coat.

looks good now lets see them on the car

[AudiA4Turbo22]

Fantastic

Yes if this F**** winter ends!

I can't wait for the spring to come and install those calipers whit new pads, new slotted rotors whit my immaculate USP summer wheels!!!

I hope that your USP wheels are reps. The wheels will not clear the B5 S4 caliper with out spacers if it is a real USP wheel. BTW, nice job.

my winter wheels are OEM 18" USP (B5 RS4) and my summer wheels are 18" USP replica" I tought that even 17" clear the B5 S4 calipers... are you sure about that? B5 S4 whit those calipers run 18" wheels I dont see why 18" RS4 would not fit ??

[davidlizard]

that looks fan-fucking-tastic....I thought mine came out nice with the black paint and the S4 decal, but the look like poop compared to yours.

I would like to see how looks your decals...and thanks a lot!

Yep hes right, I dont understand it either but its true they came on the RS4 but wont fit on the S4. I have attempted it myself.

[FourRings80]

I belive the the difference is the ''caliper height''. You might only need a 5mm spacer to clear them. You can even clear 16'' OEM rims with a 5mm spacer. I think the RS4 rims are one of the most HP2 friendly.

Excellent job. I have a set of B5 S4 calipers in the garage waiting for the spring to put on but you've prompted me into thinking about prepping them in advance.

What did you use for the polishing step on the front of the calipers to buff them smooth ?

[ziggituning]

X2, awsome job BTW.

[PCYC]

Did you clear all the stainless stuff too?

[davidlizard]

Did you clear all the stainless stuff too?

no...

I've used Walter's stuff on an angle grinder. If your not experimented whit this, have some practice before because if you make waves, there will be no way to remove it and clear coat make it appear worst...

[gunde]

RS4 replicas 17" et33 will not clear the B5S4 calipers. B5 S4 wheels will, of course, clear.

Very nice job indeed!
