Hello Friends,



I am about to replace or rebuild my front calipers. I have found very few vendors/options. If I am correct, the standard 968 calipers are also '87-'88 944 turbo calipers, correct?



Here is a vendor I have found:

Has anyone used this vendor? I'd appreciate feedback, or other suggestions.



Thanks everyone.

You can get the parts to rebuild them at SUNSET Porsche.



Looking at the picture in the like you provided, I don't recognize that as being a Brembo caliper.

Just curious...how would one determine the need to rebuild calipers? I've owned many, many cars over the years, with up to 180,000 miles. I have never had calipers rebuilt...



RS Barn replaced Master/Slave, s/s brake lines, cross drilled rotors, performance pads, etc...a couple of years ago. They didn't re-build the caliper (on my 75,000 mile car)

Scott, DO NOT USE AUTOPARTS WAREHOUSE EVER. Had a terrible experience with them over a set of 968 injectors. Long story short, paid for the injectors but never received the injectors or a refund so we got credited from our credit card company.

Thanks for the feedback guys.



Jay- my situation is that there has likely been some corrosion in the caliper, probably due to road salt. The pads don't want to pull back, away from the rotor, and they are hanging up, staying on the rotor, at times. I've been advised to pull the calipers, remove the pads, and grind the edges so that the pads will move freely in the calipers.



I'm thinking that I ought to just replace the calipers, but I have to find the right source.

The problem you are describing is very common for this type of caliper and usually referred to as plate lift. It 'only' requires removal of the steel top and bottom plate, cleaning up the corrosion and replacing/refitting these plate. The steel plates are available from eg Porsche as a repair kit. The big problem is getting the bolts out that hold the steel plates in place.

I just rebuild my breaks this winter. New pistons scrappers, and boots,came as a kit, was told that there is no aftermarket versions, and you could only get them through Porsche, each kit only had one piston, need four for the m030 brakes and they are two different sizes.

I am getting ready to put R4S pads on and I just ordered the damping plates for the pistons.



My PET shows part#24 (964-351-096-01) and part#(24) (964-351-096-02).

I ordered #24, ending in 01.



Am I correct for a non M030 car?



Thanks

not sure, but just don't put R4-s pads on slotted rotors

Bob,



Had them on for 2 years. Drilled and slotted, from the guy in CA. What is the problem?

typically slotted will tear up the kevlar of the R4-S (though oddly it has not done it on the denali, but i am chasing a perplexing deposit issue) - fine on drilled, but not slotted



you'll have to stay away from ceramic, carbon, and kevlar with slotted rotors - fine with organic and semi-metallic, though potentially noisy and/or dusty with either



slotted is better in some regards, but only with the right pad - i'm still working on that combination - not sure what i'm doing next

Bob,



Odd. I am getting excellent wear on the R4S pads with my drilled and slotted rotors.

No dust.

No noise. but a definite unfamiliar noise when braking medium hard, as in slowing down going downhill. Sort of a low frequency growl'shutter sound.

yeah - it's typical of soft materials like kevlar to wear quickly when subjected to edges like slots - they usually start off making the standard rhythmic noise and then just go to pieces - i just talked to somebody who was running them on slots and they shredded in very little time



it isn't happening on the denali though, and they are also both drilled and slotted - there is however an odd deposit issue that keeps popping up
