My car is a 2012 Carrera 4 GTS that was optioned with the center lock wheels and PCCB's. The PCCB's are off the car and have been replaced by steel Porsche OEM 350mm rotors. The calipers have not changed. The rear pads make a LOT of squealing noise when you have almost come to a complete stop with light breaking. Its driving me mad, and I cant drive the car around town like this... I did pull the pads and put some compound on the rear side of the pads and greased the appropriate parts - but not change. The car has Texar 996.352.940.03 pads (near new). Before you ask, I have done several hundred miles of hard driving and heavy stopping. has not fixed it. So I'd like to buy some alternative rear pads for this car but I'm confused as to what pads will actually fit these calipers. I don't want race pads - just some quiet.
The question is what porsche models came with this combo of rear caliper / pads - so that I can research alternative part numbers. If this is too ambiguous - what manufacture and part number alternative pads will wor
k in this car?
For what it’s worth, I got my rears replaced a few months ago. Came back in to complain about some squeaking at very low speeds (backing up) and the shop told me that, due to supply chain issues, they’ve noticed pads would be sold with higher metal content than what was previously acceptable because QC standards loosened to get product out.
Buy the OEM dampening plates from Suncoast and clean the goonoff the pad carriers. The OEM dampening pads are adhesive rubber with metal.prongs that lock into the caliper pistons and the rubber pads are large enough where the piston contacts the rubber on the back of the pad. The pistons in the calipers are different diameters and Suncoast sells mixed kits for your year and model. This is the best way to prevent the oscillation and brake squeal noise.
Also, I assume you've changed the pads and aren't running the same ones that were on there with the PCCBs as the pad compounds are different for ceramic rotors vs iron ones.
I haven't seen this style of 'damper' before. Are they supplied on the car when it originally ships from the factory?
I assume the sticky pad attaches to the rear of the pad - and the metal circle goes inside the center hole in the caliper piston?
Exactly like that. Came that way with PCCBs at least, and I use them on all my Porsche brakes now. I keep an assortment of the sizes in my parts cabinet.
This is listed under the standard 'red caliper' section. There is nothing specific in this regard for the yellow calipers - but it looks like these would work ?
