screeching with non oem pads are usually caused by not using "Brake Anti-Squeal Paste" with the new pads. Ive done it 3x times, and they were noisy each time.

Yes, I've done many brake jobs. I used the brake grease that came with the Hawk pads. I drove it a little today and did some fast stops. Much less noise, so I hope it will go away. The noise I'm getting now goes away when I press on the brake, so hopefully it will go away once broken in. Haven't driven the car that much but the Hawk pads seem to work very well and I don't see any dust compared to OEM BMW pads.

Noise is almost gone after 100 miles+ driving. I might put it on the lift this weekend and take a closer look if it persists.

I'm here to..
.....praise PF-08 pads. Yeah, they are noisy unless stone cold or hot, and they are dusty. But do they stop! I spent March 30/31 at Virginia International Raceway (VIR) with the Tarheel Chapter of the BMWCCA. My instructor, Randy Perry, had me hitting (an I mean SLAMMING) the brakes at marker 2 at turn 13! (Here's the track layout: http://virnow.com/wp-content/uploads...rse_2018km.jpg) These pads on the factory rotors NEVER faded, NEVER failed! I was able to out-brake every other car, including a couple of vettes, in my class. The pulsing/juddering noted earlier in the thread is gone. I attribute that to not fully and completely bedding in the pads. Yes, the fluid was flushed prior to the weekend with Motul RBF600.
If you want track pads that are fine (if you don't mind the noise) for your DD, then PF-08 pads are your best bet. |

pad swap - same location or rotate?
Last year I swapped in street+/light-track pads for the summer, and went back to the OEM pads for the winter. I took pains to mark the pads so they went back in the exact same location.
This year I'll be doing full track pads for track weekends, street+ pads for the rest of the summer, and back to OEM in the fall with the winter tires. Lots of pad swapping. The question is, as I do all of this pad swapping, should I be concerned about putting the pads back in the same spot? Should the Left Outer always be the Left Outer? Or, should the pads be rotated around like tires? Inside to outside, left to right, some other way? Or does it just not matter at all? My initial thought is that the pads might take a set to the brake rotor, matching any grooving in the disc. But my rotors are generally smooth, and the pads all look identical when I pull them out. I'm starting to think keeping them in the same spot is just OCD. This also assumes that there is no significant vertical or horizontal taper in the pads, no significant grooving, and the wear is generally even across an axle set. So, same spot? Conscious rotation? Or just shuffle them around randomly? |

PFC 08 on sale at Apex Performance
After digesting this thread, I'm going with the PFC 08's for track days this year. I found them on sale at Apex Performance; $260 for fronts. The Apex site is not the best but got the pads with free shipping in 2 days.

Make sure you bed the pads in properly. While the rear brakes provide only about 35% of the braking I recommend you buy pads for the rear, also.

I'm on Ferodo DS25000 pads and they are doing MUCH better for me than the Hawk HPS from last season (those worked well on street, but noisy and they gave it up on track). After a 3-day HPDE they are well-bedded, and almost no noise (and this is w/o any backing grease); very good cold braking, only possible complaint would be a little grabby. I'd read a couple of posts complaining about poor braking while cold, but these have been great for me down to about 35 degrees. It was so cold and wet that I don't think I can comment on dust, but that isn't really a factor for me.

I dropped my car off yesterday at Fall Line Motorsports in Buffalo Grove, IL for the M Performance LSD installation (woohoo!) and a brake fluid flush with Motul RBF660 that I supplied them. Before I left, I remembered to ask about brake pads too, and after some discussion and customer references they gave me, I ended up emptying my wallet for some Pagid RSL29 endurance pads. $630 after taxes! That is not including the labor @ $175 an hour. I could have saved a $100 or so going with some Hawk pads, but figured what the hell... I won't have the time to take on the work myself and I have a 2-day HPDE coming up in less than 2 weeks. Still need to find the time to change engine oil by myself and hopefully install some wheel studs that I bought a while back as well. What is the verdict on the Pagid yellow RSL29 from those who have experience with them? The boys at Fall Line Motorsports swore by them and after walking for a mile in their MEGA warehouse filled with race cars and like 6 semi truck trailers, I figured those guys are about as serious as it gets when it comes to track prep. Kind of took their word for it. I was told they are a medium friction pad that won't trigger ABS easily and will work great with my PSS tires, but will still handle track abuse with ease and give me all the benefits of a serious endurance track pad while being easy on the rotors. I was warned about squeal and dust, but oh well. I bought the car to enjoy on track and really don't drive it much on the street anyhow. I didn't ask them how long I can expect them to last in terms of # of track events, however. What is considered "average" for replacement intervals on these endurance pads like RSL29, PF08, PF11, etc.? Just hoping I didn't spend $630+ on brake pads that will only last me 1 or 2 events. If I can get at least 3-4 events worth of worry-free, consistent braking, then perhaps it will end up being worth the investment. I'll be sure to come back and share my thoughts and experiences after the weekend of May 18/19th!

Uh oh! I was told they should still stop okay on the street. One of the guys said the Porsche GT3 uses these as OEM pads??? Not sure if that's true, but if so, I can't imagine Porsche would supply them on what is technically still a street car if they were dangerous to use. Would love to hear about some 1st hand experiences out there!

The only reason the yellows won't last you a long time is if you're especially hard on your brakes. You can burn anything up if you abuse it sufficiently. I don't know what your experience level is at the track, but drivers that are hard on their brakes are generally spending more time on their brakes. Even though they're going faster (assuming equal cars), advanced students and instructors tend to complete their speed reduction pretty quickly by braking harder for a shorter length of time. Expect to feel your ABS. Something to remember is that the purpose of braking at the track is to reduce the car's speed only enough to enable it to turn-in to the corner at the edge of traction. Pros get paid because they can do that consistently; the rest of us over-slow to one degree or another.

We just did front and rear brake pads on a Porsche GT3 and the Porsche genuine pads are Pagid, but they are not the Yellows. |

Any markings on the OEM Pagid GT3 pads that might indicate what they actually are? Just wondering if they could be the same compound as yellows, but without the yellow color as to not interfere with Pagid's (or Porsche's) marketing efforts.

Just did my first HPDE of the season on EBC yellows. Worked well for that. I've had them on for a few months, so they've been broken in. No fade and good bite, but still noisy as hell in stop & go traffic. Enough dust to make any wheel look like shit after a week or 2.

No, didn't see any specific markings. The characteristics of the pads are more street pad like than yellows as well.

They're ok for street driving cold. And yeah, they squeal. But, it's a track pad, anything in that category is noisy. Quote:
As dradernh mentioned, this is mostly about driving style, and you can definitely be quite fast without overheating them. I've been trying some Hawk DTC-60s while I set up better brake cooling, and the first impression is they don't seem to crumble as much. Also, quite a bit more initial bite. But it's hard to tell from just a single set. Oh, and I also had someone with a GT4 notice my box of spares at the track, and mention his car came with pagid yellows stock. As HP Autosport mentioned, maybe confused about another pagid pad. |
