Quick 996 question

[tomwood_uk]

Has anyone had pad/disc clearance issues with the 996 calipers and 323x30 discs? Just putting the kit together atm and with the pistons fully retracted the new pads are tighter than I'd like on the disc. I'm sure this has been answered before but the search function is useless on my phone

The 996s are designed for use with 28mm discs. That is why you need to remove about 1mm of material from the pad guide pins on each side. Pads should still fit fine though, but different brands will all be slightly different. What have you fitted?

[tomwood_uk]

Yea I've removed the material off the guide pins to allow for this, but the new Brembo pads sit slightly proud of the pins making it a tight fit.

Also the new pads didn't come with the backing plates fitted that locate inside the pistons. Are these interchangable?

I never fit the backing plates now, just a smear of copper slip on the back of the pads. I've not had groaning and squeeling issues since. You do get a rattle from the pads in the carriers though and maybe a clack the first time you use them from cold. I have heard of some people skimming a mm of friction material off but I've never had to with Ferodos.

Cheers mate. I might just file a little of the pads to get me started.

Never had an issue but as above, it'll just be the brand of pads that are a bit thicker.

My pads howl like hell at below 40mph if theyre warm. Ive tried without shims/with shims/with shims and coppergrease. Does any one know of any tape/adhesive i could use to stick the shim to the pad?

[s2driveruk]

Mine used to ring but I switched to textar brake anti squeal and been silent ever since. I use the shims but they've never been stuck to the pads. I'd double check that a pad carrier itsnt touching the disc...thermal expansion can cause issues with clearance. Other possibility is corrosion on the outer edge of the disc touching the pad retainer, again resulting in low speed noises. Hope that helps...

Good points! Cheers bud!

Copper gasket. Works a treat and I've got some here you can use

Ahh good thinking, i can imagine that works quite well! I may take you up on that!
