944 Turbo front brake caliper enigma

Aha good, thought I was going mad there lol! Yes if the shims don't sink into the pistons they are incorrect!

Hope you get it sorted soon, I went through all manner of permutations with the front brakes until I eventually got the squealing to stop. OEM shims in the end were the solution but not cheap at £20 a shim times 4!

Incidentally I have no shims on the rear and they are quiet but the front ones would not shut up until OEM shims fitted.

Cheers

Cool. Be good to meet up, not many 944T's in Glasgow area!

Haven't got a PM btw, will clear my inbox just in case.

Cheers

That's what I said!! Said stupid cylinders screwed onto backing plate should disappear snuggly into the pistons and the backing plate should then be fixed to the back of the brake pad!

I know you had it right just mis understood

as were on brakes and the problem is solved ........I was just looking for somewhere to post some pictures of calipers I have just refubished for Steve ...they came out really nice

Nice I just had mine refurbished red as well. Where did you get the old school decals from? The decals on my callipers don't look right as they are a more modern logo

Apologies for the delay in closing off this thread (I blame my 1 year old and 3 year old!) :roll:

Anyways I contacted Design 911 and got the parts changed - Huge kudos to them as there was over a 12 month period of time from ordering the parts originally and they swapped them no problem

The right part number 95135108903 with sizes of 19.7mm and 27.3mm - Slotted inside the pistons properly and calipers now on the car with new discs. Turns out my car was indeed a 1989 year of manufacture model but wasn't registered till August 1991

I had the disc type shims in two of my calipers, nothing in the other two ... I've elected to run shim-free from now on lol... let's see how that works!!

Don't blame you

They are freaking extortionate for what they are. I think if I was doing the job again I would try it shim free and see how I get on

As previously stated shim free for me = squeal! Lots of squeal!! Maybe others will have better luck. Incidentally my brakes have started screeching again after spirited use, I am hoping a good copper slipping will cure it. Will need to take the calipers off though because the pads don't slide out when the shims are stuck to the pads!
