Pagid RS29 brake pads: clunking noise when changing between drive and reverse.
I have installed Pagid RS29 pads yesterday. Went out to bed them in late at night. In general very happy with them so far, autobahn performance was good. Will see how they perform in the track over the weekend.
There is much less noise than I expected, very occasional and brief squeaks, I could actually live with this as a daily drive. (although I realize this might change after a track day) On thing that really bother me though: when I park, i.e. every time change rolling direction from D to R or the other way around, there is a very pronounced clunking sound from the brakes (I think both sides). It gives the impression of loose brake pads hitting the caliper as the brake rotor pulls them to the top/bottom. Anyone experiencing this? Maybe with other pads? I do understand these were developed with racing in mind and are meant to brake the car in the most efficient way from a forward movement, but shouldn't be too hard to replicate the OEM pad size for a tighter fit if that is the source of the problem. During installation, once the calipers were spread the Pagids went in really (can I say "too") easily. The OEMs were a much tighter fit. Off-topic: My OEM pads looked really ugly. They have a total of 10k km in them and 1 Track day. The outside liner was completely cooked/cracked and peeling off. I am wondering what BMW will say when they get to replace them under my extended service program. |

Normal, mine do the same.
While it is slightly annoying, I find this slap far less disturbing than the bad squeal some track pads display when driven on the street. The RS29 only peep once in a while.

Normal, although CarboTech's don't do this

Maybe, but I heard they squeal more than a garbage truck does though

Not true. Carbotech does state this but so do many other manufacturers. Bed them at the track and they work well. Drive home on cold rotors and they scrub off the transfer material and then the OEM pads work fine. Lots of us running them for the track and switching back to stock without any issues. I worried about this too but after talking to a couple of shops that are experts on this (and don't even sell Carbotech), decided this is often just standard disclaimer stuff.

Guys, the OEM pads annoy me, not enough initial bite. Are the RS29s a barely noticeable improvement or should I go ahead and purchase them for this reason? Car is on the track a few times per year but only interested if I can see an improvement in street driving. Also, I'm assuming these barely squeal? I have track pads on the other car that screech like a bus, don't need another car that does that.

As for RSL1, they are a different compound not compatible with OEM pads (for switching back and forth). Once you go to RSL1 there is no going back unless you change rotors. (maybe with some sophisticated machining, not sure that makes sense) Cant say much on their noise levels, I would assume they are worse. They are also a bit more expensive and probably have an even less street-friendly temperature profile. Taking into consideration all of the above I would stay away from them for mostly street driving. |

My RS29 don't squeal much at all. I have had them on the car since early may which includes 5 track days. I also DD the car and it's been pretty good so far, only an occasional peep. They do slap on forward to reverse brake application, but I can live with that slight annoyance.

The Carbotechs are so noisy it would be impossible but if I could put RS29 on and leave them in all summer, that would be ideal to avoid pad swaps.

The early PF08 that I used on my E92 squealed real bad, so I swapped them at every event. Eventually, they came with the retaining clips (early PF08 did not have the retaining clips on the pads) and they stopped squealing. I was also told the PF modified the pad compound, but I am not sure how accurate that is. After that, they became decently quiet and I no longer bothered swapping them between track days. So far so good with the RS29. I certainly appreciate the convenience of not having to swap the pads. I also find that track pads offer a better pedal feel for street use. If I plan a long road trip or a longer stint without tracking, I do swap back to OEM pads for reduced disc wear, less brake dust and quieter braking.

[QUOTE=gthal;18111470]Interesting. So you both leave the track pads in for the entire season? Do you put OEM back for winter?

This is really all you need to know about the clunking. The yellow one is the rs29 in the first pic, and the rs29 is on the left of the second pic as its a bit dark with the opposite side matching up fairly close.
I believe they are hitting the pins. I don't see any wear marks on the calipers themselves although I don't see any on the pins either so it could be somewhere else. |

To all of you that can actually keep the RS29's in full time, are any of you stuck like me under 40mph for weeks on end? I've had other cars with RS29, RS19, RS44 full time but when I lived in cities where I could actually get up to some speed and use them occasionally and I've been told that I brake harder than most would expect when people ride with me.
It seems like here they squeal much worse than I have ever experienced but I would be surprised if I ever got over 40mph for a tank of gas and its always a really slow stop that could nearly be accomplished by the revs only. |
