@Kostamojen You didn't bed the pads properly. I have the same pad, BP20. It doesn't squeal loud. I sometimes hear very quiet squeal when braking at slow speed. Drive your car when no one is out there and just brake the sh!t out of it right before it fades. Repeat and you'll be good to go. Or attend any HPDE in your area. That will bed in your brake pads for sure

I'm going to try to go for a drive tomorrow, and I have an autox next weekend. Actual track day would be maybe in July, but I'm driving down highway 1 the beginning of May so maybe then it will be broken in?

Kostamojen · 04-09-2016, 11:50 AM

Well, its pouring rain today... No bedding in for me today lol

Kostamojen · 04-10-2016, 10:17 PM

Question: Is anyone else running BP-20's with the DBA rotors?

frslee · 04-11-2016, 08:44 PM

Just came back from Trackdaze OpenTrack event at Summit Point Main Circuit. Front sport performance kit + BP20 pads performed very consistently. I'm at intermediate solo level, so I'm not "there" yet. Braking distance was improved a lot compared to stock calipers + Project mu hc800. It cools down faster, so it's ready for the next braking zone. It was kind of pity that I had regular summer tires, so I wasn't able to squeeze the maximum cornering today. Overall I had great experience with this kit. I look forward to experience more benefits from this setup few more times this year. Great kit Rafi!

Noise no, dust yes.......before I properly bedded them in they were very noisy at low speed.

So i spent some time late last night doing propper bedding in procedures per instructions. You can physically see a difference in the rotors:

The bad news is, it went away for awhile but after doing some normal commute driving the squeeling is back.

I have some BP10's that came in yesterday im going to install Friday and bleed the brakes a little too just to be sure everything is 100% and try again.

DocWalt · 04-13-2016, 07:27 PM

Yep, "normal" sane person driving will wear the bedded in pad off and make it squeak again.

You can see that you rubbed off the crosshatching, which is a great start. The BP10s should be a lot quieter right off the bat now.

Kostamojen · 04-14-2016, 10:45 PM

I put on the BP10's, and immediately they were SIGNIFICANTLY louder... I need to bed them in a bit more I presume, but right now I'm not happy.

ajc209 · 04-15-2016, 05:34 AM

Either you need to run a soft OEM like compound or except that with "normal" driving you'll get some squeak with hard compounds. Generally the higher temp you go the worse it get. You should heard my club racers!

Surely its an excuse to go for a hoon?

DocWalt · 04-15-2016, 09:35 AM

I bet the BP10s are enough of a compound change that they'll need bedded in again. Get them HOT.

frslee · 04-15-2016, 10:00 AM

@Kostamojen everytime you install new pads, new bedding procedure is required. Don't be Not-Happy! Just be patient and bed those suckers at late night and you'll be good to go. After I came back from track, my brakes are absolutely quiet. Hard braking does the wonders.
