Do you guys have the RPV's or are you having the issue without them?

If it's without, it sounds like you aren't getting enough pad retraction. Maybe try the factory grease if cleaning doesn't help. Just a thought.

No valves. I've got a few track days, pad swaps and many street miles on the calipers and this squeak started about a month ago.

I'm not going to do this scientifically to see what fixes it, but I am going to:
Pack in RRG
Swap back to the original dust seals (I have the RB ones now and they never fit great TBH)
Install new Posi-Quiet pads (105.16630) meant for the Macan
Lube pins/pads with Permatex Silicone lube (24129)

Will report back!

If the dust seals didn't fit great I can see those not allowing the pistons to retract properly. The Macan calipers are low drag (hence why the pedal can feel squishy) so I'm surprised you're getting drag in the first place.

I drove my brother's R with the stock 340mm single piston calipers and his pedal feels way stiffer than mine but the brakes don't bite as well at all. I vastly prefer my softer pedal feel now (at least on the street) now that I'm used to it.

They fit the piston great, but didn't fit as snug in the caliper as the factory parts so that could be contributing to them not retracting. The seal isn't tugging back on the piston at all if the seal is just floating.

The dust seal shouldn't be pulling back on the piston; that should be done by the square seal inside the piston bore (unless I'm misunderstanding what you're saying).

I drove an R and my GTI back to back at an autocross this last weekend. Pedal felt identical to me.

I really liked the R. Good thing I didn't drive one before buying the GTI. Lol.

No you're good, I'm probably giving the dust seal more credit for piston retraction than it deserves. You had said if it didn't fit well it could be hanging, but the seal is loose in the housing so if anything it's just not doing it's job sealing.

I was just thinking if it was hanging it could be getting in the way of the piston retracting properly, but it's just a guess.

I always forget what the consensus was, but I think I have the even smaller M/C since I have a 1.8? Either way the brakes work the way I want them so I'm happy.

So question. I have gone thru like 25+ pages on this thread. I am considering doing this upgrade to my fronts. I have a non PP Gti, so little brakes. However, with upgrading the front, do I need to upgrade the rears to the macan rears? If so… are there listed part#s?

also really stupid question… because im just curious. Could you use front brakes as rears? Idk im just wondering.

No and …I don’t know if anyone’s tried that, but likely no.

No, no, and not needed. The non-pp rears aren't an issue at all.

Rear brakes have the parking brake integrated, so no you can't put front calipers on the rear.

After a long time, I had a opportunity to test the Macan Brakes on track. Unfortunatelly the car had DSG problems and just did some laps.
I'm happy with the result so far, but need to test more after solve the DSG issue.
