Racingbrake rotor and Pagid RS29 pads

[justpete]

Anybody used these pads with RB rotors without deposits and judder?

You should be fine with RS29 on RB rotors.

Quite a few GTR and Corvette track guys run this combo w/o any issue.

Thanks very much.

If you are having problems I'd wonder if they were properly bedded in (something I don't have to mess with since I run PFC08's PFC brake pads).

No problems, thanks. Am currently running XP10 on non-RB rotors but am changing over to them and am aware of the problems with these pads. Wanted to make sure I wasn't going to have a similar problem with the RS29. Doesn't look like it.

New rotors and new pads gives you the perfect opportunity to do a proper pad bedding per Pagid's procedure. You'll be fine.

Excellent! Thanks very much.

I've run xp12/10 and 10/8 and never jutter. Not sure what may be the case? Deposits come out with the air nozzle at a gas station :

RB indicates these pads tend to leave deposits under high temp operation that lead to judder. Bought the front rotors to test with XP10s but never got around to it. Changing rear brakes to e46 M3 CSL rotors and 135i rear calipers now so thinking it's time to put the RB front 135i rotors on and change pad type on all corners. Hesitant to put the RB rotors on and muck them up with heat related deposits if the XP10s are really the problem they say they are so needed to verify the RS29 pads wouldn't lead to the same potential problem.

Yeah, I've read some horror stories, willing to give it a try since the car isn't overpowered and is getting down to 3000 pounds, unladen. Doesn't look pretty though, that's for sure.

racingbrake Comments?

With said above pictures and xp10 problems at this point stock seems better?

It's weird that a rotor company says that's a certain pad has problems when there are a ton of people using ct pads. I like them because my rotor wear has been very friendly with multiple xp12 (only tried one set of xp10). After track day I throw on oem pads for street. I never bed neither pad.

135i caliper and e46 rotor is a unique setup. I know the 135i front calipers look beefy but they could barely halt a 135i that great (my wife's car), which is pretty much same weight or less than m3.

Pfc08 is one I've been eyeing and against the xp12 I would guess a little less initial bite but way longer lasting (endurance pad right) and killer on the rotors?

Thoughts?

The picture is unrelated to the pads in question as I understand the post.

They don't say Carbotech pads are a problem, they're responding to users who've had judder problems. Not like it's a big deal or anything, just use a different mfg's pad.

I don't care about rotor wear but the XP10 (pre-bedded by Carbotech) certainly are rotor friendly.

The 135i calipers work fine after upgrading the pistons, seals, and boots. It's been easy to get 1.2g braking deceleration with XP10 front and rear (stock rear calipers with solid guide pin bushings) and Toyo R1R tires. Brake fluid is Torque RT700.

How'd you like them over stock? Those gs are doable with stock setup too.

Couldn't get over 1g with stock, btw. That was with stock staggered tire setup on Pirelli P-Zero RFTs though.

The XP10s have a lot more bite and zero fade. Can also get deeper into the brake zones, easy to modulate when trail braking, clean release, etc. Pretty much what you'd expect. Really like them.

I do over 1g braking all day

Lol. I'm just saying I'm not sure it validated your 1.2g braking because of the parts that's all. As long as you're happy with your setup it's all good.

No worries. I have a Race Technologies DL1 Mk3 datalogger in the car mounted just above the SRS module in the console. It's been there for a long time so I have lots of data from several tracks where I can look at lateral and longitudinal g forces in detail, including peak values, friction circles, etc. So it's easy to compare tires versus braking force versus brake pads. The differences are small but clearly an increase with the XP10 pads and 135i front rotors compared to stock rotors and calipers on the same R1R tires.

Steer well clear of RB IMO.

Edit:
Sorry if the above sounds patronizing, I just remember my life flashing before my eyes before the hill drops away into Turn 1……...

Didn't sound patronizing, not to worry. I understand your concern, and the sphincter factor of losing brakes at the absolutely worst possible time on-track, btdt.

Like anything else, a failure analysis is really needed to put something like this in perspective. I watch over the details quite carefully and am paranoid about anything out of the ordinary. Should anything untoward crop up with the rotors they'll come off the car, I have two sets of other rotors to replace it with should it become necessary.

Actually it'll be interesting to see what the rotor and hat temps get to on the track, as well as the caliper temp. And maybe I should carry a spare rotor with me to the track, couldn't hurt. I do appreciate the heads up on your experience, it'd be helpful if others can join in with their experience as well.

PFC08's are easy on rotors and long lasting b/c they are an endurance pad.
