Brake Pads

[H823ENM]

Could someone please confirm if the front pads on an S2 should have locating studs, as I'm concerned they may chatter.

Thanks

The pads themselves will be flat on the back and they just slip in to the calliper. Porsche sell anti vibration pads which are supposed to stop any squeal or chatter. They look like a spider with a sticky pad on it's back, the spiders legs clip in to the pistons of the calliper and the sticky pad attaches to the back of the pad. I've never used them, but smear the back and sides of the pad with copperslip and that stops any squeal Last time I checked, they cost £2 +vat per spider and you need 4 per calliper

Some aftermarket pads designed for Porsche cars have built in anti-squeal shims as well which also negates the need for the tape on things that you are supposed to use with stock pads.

Does anything work with Pagid Yellows? - I can live in hope! [][][][]

Having just had a rough time with pad rattle on the back of an S2 (it's hellishly loud), I can confirm that my pads have thick sticky/spongy pads on the back of them but no springs or spiders, as per Paul's description. The chatter is dealt with by means of the cruciform springs, which hold the pads in place. These should need to be forced closed, against the edge of the brake pads - thus holding the brake pads firmly in place. If these springs are slightly twisted, or the caliper plates (which define the stop point of the pads) are slightly bent, the pads will not be held tight and the pads will rattle. To make things worse, the cruciform springs are slightly curved when in position, so as the pad wears, it moves into the middle of the curve and gets looser ... (A good bit of plate lift would cure the whole problem, but we are not allowed to expound that as a good idea on here!) Oli.
