My offside rear brake began squealing really badly on the way home tonight so I removed the wheel. Could not see anything untoward so I opened up the caliper to make sure there was nothing wedged between the disc and pads.
I then noticed that there are no pad backing plates on any of the pads. Does anyone have any idea why? This may be the reason the PCCBs have a tendency to squeal as I thought these were called anti-squeal shims...
p.s. Can a mod edit the thread title - it's doing my head in!
You are not necessarily correct in assuming a backing plate will affect the
PCCB
squeal. For all you know, the back of the pad may reach temperatures that'd anneal the plate and possibly shatter it. All ceramic brakes suffer from extremely high conditioning temperatures. Unless you continuously use your brakes quite hard, the pads will galze-over (just like steel ones will). The only caveat is that what's considered "enough heat" to de-glaze normal pads is barely heating-up ceramic pads;
Here's an indication: When a Bentley that has specced optional Ceramic Brakes comes in for service and the customer complains of squealing brakes (which, unless he drives like a maniac he will) all the mechanics do is take the 2-ton car, drive it up to 120mph and stand on the brakes until stand-still. Repeat this five-six times and the squeal is gone, for a few months.
Now I'm not suggesting you have to go to that extent in your
Cayman
, but it's quite certain that de-glazing will help your squealing issue. Just be aware that de-glazing Ceramics is much, much harsher than steel.
Of course not, but I'll give it a go anyway!
Mine screech when braking. Not while driving, but slow braking. I've been to the dealer a couple of times. The only thing that calms them down is beating the car on a windy road or track. This will fix it, for a while. Beat, then repeat!
Mine never squeal although i had other problems today after track day left front metallic noise .
Tomorrow i'll go visit the shop cause the new pads he put on me 500km before
cause me troubles i think .
Saw some bad things on the left disk when home . Iam quite positive that although i payed for oem pads i got something cheaper instead .
Could not see the made in Germany thing from outside the wheel with a code underneath .
I hope i didn't damage my left disk something wrong with the pad after track heavy braking , saw trail marks on disk and heard metallic noise on turning points on the way home .
Does anyone know the part number or a link with front oem pads for
PCCB
??? (for
cayman
of course)
