Super impressed with the performance of the RS29 pads I've got on my 996 C4S, However the noise is making the car an absolute nightmare to drive on the road.

I take the car into work and on little non-ten tenths excursions from time to time and I find myself reluctant to press the brake because of the squeal. To be honest its really embarrassing.

I did expect some noise but I can't imagine how anyone would be able to put up with it for road use. No amount of hard stops will clear it. It's driving me mad.

I'm considering swapping back to standard pads. Before the pads go on ebay does anyone have any tips to reduce the noise?

Ta!

I have ran 2 Porkers with RS29 and both have been quite

My mate fitted RS29 and he had to take them out. or a shop did for him.

what's the issue to this, I am not sure but 1st.

did you clean your old disks, and I mean put a drill though the disc holes, and sand the disc.
did you add the Pagid CeraTec Brake Lube to the pins and springs on the calipers.

did you then follow the bedding in to the book to allow pad transfer to the disc (this is why you clean the old disc as much as you can)

when I have done this to both my GT3 and my R the pads did not make a noise, just the odd one if I ended up in town to often, a few 100 mph stops would cure that.

Ditto above.

The squealing will stop once youve bedded them in. You will need to do some big stops from 70mph. Build the pressure on the pedal immediately the brakes have started to bite.

Thanks for the suggestions!

I did bed them in when new according to Pagid instructions. Then proceeded to do a full day at Spa and then Ring so wasn't exactly babying them!

Went to amsterdam right after the trackday (Can recommend!) and the noise around town was unbearable. Anything below about 30mph thats not standing on the pedal creates the most horrendous squeal every single stop. Been like that since despite some good road workouts.

Had new rears fitted when they went on. Front discs were not changed, or cleaned as far as I know. Maybe thats worth looking at. I will try to see if the rears are making the same racket.

I'll check with my Indi about the grease question, How would this create the squeal?

It's possible. I had new discs at the same time as I had RS29s fitted and they did squeak a bit at first, even after proper bedding in, but have since settled down. There's just the very slightest noise on slow stops in traffic.

Seems to me that your discs are glazed, or they forgot the shims and/or paste. You need to get the discs skimmed and cleaned properly, and the pads properly reinstalled. My RS29s squeal a little from time to time, but not so much that I don't want to brake...

I fitted mine with new discs and needed them as per pagid instructions. They've never squealed so skimming the disc might be the solution.

I've run RS29s on a range of cars, never had a prolonged issue with squeeling. Have had the odd bit until they were bedded in properly but that's it. Are you sure it's not the dust shield touching the disc or similar?

Been here, done this ... Twice.
Street driven (hard) 996 GT2 and M3 CSL.

It'll be the rear pads, incorrectly bedded or glazed (as a result of the above) you may think you've heat cycled them sufficiently, but I'd suggest you haven't.

A few options :
Chuck 'em (or sell them to hardcore trackdayista)
Lend the rear pads to a hardcore trackdayista and let them get some serious temperature into them (of course if they are already glazed, this probably won't help, they'll merely overheat the pads as they're toast already. Been there, done that)

Fit standard rear pads or go to something like Pagid RS19's

Aren't RS19s more or less the same as the 29s but with a slightly lower friction coefficient?

Slightly less initial bite and a more "wooden" feel.
