Consolidated Macan Brembo upgrade thread (READ FIRST POST)

Sorry for the dumb question, but I have some brake paint on the way. What are the 6 point bolts on the caliper for? I imagine they're to keep the two halves together and I probably shouldn't touch them for painting (just mask and paint around them)? If I'm going to pull the pistons out and regrease them anyways, would it be OK to remove the bolts as well?

They hold the two halves together. You can opt to remove them prior to paint, or paint them with the caliper not split in half. I would avoid painting the heads regardless, the paint will chip off the second you put the e-torx socket on, even if you taped over everything.

Thanks for the reply! I think I'll just mask them off and paint the caliper as a whole.

Just did this swap on my PP car, pedal is going to take some getting used to but I like it. To add to the wheel fitment, Motegi MR135's at 18x8.5 +45 do not clear the face. I needed a 7mm spacer to get roughly 3mm of clearance between the spokes and face of the caliper.

Did you do the adaptions, red rubber grease and high pressure bleed?

Once I did that, pedal feel was back to stock.

How long do we expect the red rubber grease to work? Is this a "you're rebuilding your brakes every year" thing? I don't trust the residual pressure valves to hold up to year round salt belt driving so those aren't an option for me.

Slightly OT, but anybody know if the TTS brakes are "high retraction" brakes as well, or do they perform as desired right off the bat?

I've heard same complaints with TTS.

RRG has been on a few months and all seems fine. Honestly, the high pressure bleed after going with RBF660 had a much larger affect than the RRG alone.

I'm still waiting on someone to measure their M/C, but there may be two different M/C diameters (23.81mm and 25.4mm) floating around. The Macan/Q5 uses a piston diameter of 25.4mm for their M/C.

By high pressure bleed do you mean using a pressure bleeder instead of using the two person method?

Yes.

Replying here to avoid continued off-topic cluttering of the Neuspeed BBK thread, but if @emichel6888 is correct about the later R M/C being 25.4 that's intriguing. Any idea how big the rear pistons are on the macan/q5?

Macan/Q5 P/N is 8K0615403x, which corresponds to ⌀43mm

PP GTI/R looks to be ⌀38mm

If we could get a part number for the one with 25.4 that would be awesome. Might be why some have pedal feels issues when upgrading and others don't???

The issue is that the P/N isn't actually printed on the M/C itself lol. So the only surefire way is to order from the dealer the 5QM P/N and see what comes.

Hi, I change the caliper to Brembo Z18 from a crashed Audi Q7 with 350mmx32 disk.... Y have to test if fit ok in my car. Today I`ll make the first check.

Someone know wich disk is correct to fit in S3 V8/Passat B8 whith this caliper. The original disk from Q7 dont fit in my car.

I don't know the answer to your question, but I'd guess the 345mm disk we've all been using might work?
