I do know that on my 997 damper were fitted front and rear.
Leading evidence: 'Install front and rear' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'could have been reused' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Install front and rear' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I didnt change mine for the front when I changed discs and pads.

I re-used the rear ones as they came apart from the pads very easily with a gentle pry and I knew had been changed quite recently (indy replaced the pads, but for some reason left the grotty discs on).

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Outcome without a verified action link
Its possible that yours have fallen to bits, and the plate has detached from the cylinder which is still stuck in the pistons.
Does anyone fit these/is it worth fitting?
Also because the plates have cylinders that fit into the holes in the caliper pistons presumably its impossible to stick the plates to the pads and them put them into the calipers..??
Or do you have to remove the calipers, put the plates into the caliper, then stick the pads to the plates and then refit the whole caliper inc. the plates & pads...??
Do you actually have to stick the plates to the pads??
Thanks!!
Just like pads they can be removed without removing the caliper, as they are cheap service parts, I usually just replace them. Remove the pad first (you may have to pry them apart), then remove the damper. If the damper plate has been re-used before, it will likely break apart anyway.
You don't 'stick' them to the pad, most tend to put a thin layer of Ceratec, or similar high temp grease on the back of the pad, which does tend to fuse the 2 parts together after many heat cycles!
Happy wrench'in! :thumb:
Thanks!
So presumably then I/we can fit them into the calliper first and then slide the pads in afterwards?
Are they necessary though?
I've a feeling I've only got them on the fronts, is there any logic in this or should they be in the rears as well?
This gives you a good idea of how they fit together. This guy is replacing the discs as well, so no need to remove the caliper to replace the shims and pads.
Are the necessary :dont know: Well that's debatable, I would say yes, as that's how they left the factory.
I do know that on my 997 damper were fitted front and rear. Take a look at your PET for more info on your model.
Thanks for that link! Very useful - he just put the plates in and then the pads without sticking them together or using any grease....
Just had a look at my old pads, the fronts had plates with the metal cylinders fitted to them (which fit into the pistons) but the rears just have a plate (I think it is) but without the cylinders...?
(It's a C4S therefore has C2/4 fronts on the rear and Turbos on the front)
The rear anti-vibration plates are a different design to the front, but the basic principle is the same, ie a short cylinder that slides into the piston, attached to a plate that meets the pad. Its possible that yours have fallen to bits, and the plate has detached from the cylinder which is still stuck in the pistons.
I re-used the rear ones as they came apart from the pads very easily with a gentle pry and I knew had been changed quite recently (indy replaced the pads, but for some reason left the grotty discs on). I replaced the front ones, but they were in-tact after I got them out and I suspect could have been reused.
I found the only way to refit them is to take the caliper off (which is really easy and quick), push the new anti vibration plates fully into the pistons (and make sure they are fully retracted), refit the caliper, then slide the brake pads in. Its fiddly though as the glue on the plate keeps sticking to the pad!
The clearance between the pad and the disc is tight anyway and I cant see what extra good a bit of glue would do when the pad is under even the slightest pressure.
Thanks Robert, I had a look last night at my old pads & remains of plates I'd already taken out and I'm pretty sure the plates have a sticky side to them which is then stuck to the pads.
The only way then it appears, is to first remove the caliper - fit the plates into the caliper - and then the pads - and then re-fit the caliper.
Otherwise it would be a pig to slide the pads is because of the sticky side to the plates....
I thought they were something daft like £80 when I looked. Can't remember which way round it was, but one end is single piece and the other end are individual ones, the individual ones are silly money.
MC
The H Tec ones one carparts4less aren't too bad, in one of their many 20% off sales... £70ish for a whole set.
But yes OP, you could fit the pads and plates with the caliper off, the trick would be putting the pin the pads slide along back in as you need to tap it with a hammer. Perhaps you could get it in enough to refit, then tap it in after bolting the caliper back on.
I've since ordered a new full set of pads and plates and will, as discussed, remove the calipers to fit.
Does anyone please know the C4S specs for the 2 main bolts that hold the calipers on - they are different calipers f & r therefore presumably different specs??
The video above mentioned 63 ft lb, i think it was, but is this for just the fronts/rears/ or all round??
Thanks!
I'll just say and leave it at that .. brake disc damper shims .. the ECP ones and indeed the aftermarket ones in general have a crap type glue that does not bond well to the pads .
Been there .. tried that and gave up .. Porsche ones whilst expensive do the job first time around .
Bolts at 63 ft lb is fine front and rear .
