Performance brake pads and squeaky noise
 

Had my Brembo BBK installed today with CSG performance pads. I was told and warned these pads will produce squeaky noise when braking. I’m definitely hearing it each time just prior to car comes to a complete stop. It is a loud high pitch sound. Will the noise be subdued over time or just something I have to live with?

Look up how to bed your brakes and go have some fun. This should cure your issues.

I have no idea regarding the pads you are using but some brake pads, that is track/race pads, always squeak/squeal when driven on the street. The good wife, and to a lesser extent myself, hate driving around town with XP10s fitted. The very loud squeal doesn't let up and they never get hot enough on the street for the noise to go away.

Same issue with Project Mu 800+. Excellent pads for track days, but usually quite squeaky on the street.
I just tolerate it, since not sure if it's a good idea to swap in the stock pads between usage and my car is already loud anyway.

I like these posts.

The oven is hot and it will burn you!

Hey I stuck my hand in the oven and it burned me?

1) Properly bedded pads, including track pads, in most cases are quiet
2) During normal daily driving on public roads it's hard to get enough heat into specialized brakes/pads, especially if driving during legal limits, so most often case with track pads is that even if you quieten them down during track days, during light braking of daily driving bedded layer (from heated up pads material transferred onto brake rotors) will soon wear off and you are back with squeal, which no, won't subdue by time. You may try to re-bed brakes, but after few days squeal will be back. Even harder to get enough heat for bedding during DD with aftermarket BBKs, that have larger heat capacity and cool off quicker/more, so sometimes with BBK it makes sense to move step down in pads more to street for same noise/performance as stockers.
3) best possible scenario is to have two set of pads and change them depending on use prior/post track day. Right tool for right job.
4) if change is not feasible, choose your priorities, quiet brakes during daily driving or high temp range/consistency/better friction of track pads performance, or some hybrid pads in-between (but which might be not ideal DD pads nor be up to job on track)
5) you've been properly warned about possible issues by CSG, so nobody to fault but yourself that you ignored warning, even if in reality your priorities of noise vs performance might be different. see (3.) & (4.)

I like your wheels op

I'm not a track pad expert, but won't those pads have poor performance until they are hot? Like on track hot?

Not blaming anyone here. Just want to make sure the loud high pitch sound is normal. My previous car was IS350 F Sport which also came with performance pads stock, that would squeak too but not this loud.

So in short, the noise won’t go way with time, it’ll only go away when I push the car hard on track days?

Most probably. And even after track day, squeel may soon come back.

See last sentence of (2.). For more powerful and heavier cars that may have been a bit underbraked stock, sometimes even higher rated pads may work fine. Twins are relatively light, and even stock brakes are somewhat adequate. On top of that you upgraded to BBK. That very probably is why on IS350 performance pads may have been quiter (that is if pads on it are comparable to ones you bought from CSG, instead of being just some hybrid pads with "performance" only in name for marketing reasons). I recall post of CSG Mike that wrote about his experiences on eg. S2000, where it was easier to bed brakes even with higher rated pads then on twins.

So. Reread (3.) & (4.) and decide what matters to you most and do pad choice according to that. I can even advise to ask CSG guys as good advisors to which pads may fit _your_ needs best. Tell them what tires you are running on, what BBK you have, for what purpose you need pads for, track or daily, and they can advise what may work better for you and what might bring issues (such as yours, with squealing) and what you shouldn't buy. They have told me not to get some stuff i was under impression that i may need, they are not into this just to make sale no matter what.

What pad are you running?

You need to bed them in, they will be much quieter afterwards. I am on XP10's all the way around and they only make noise at low speeds but it is not too bad. Much better then the PMU HC800+ I used to have, those things were always loud.

Brembo TS20 is included with the CSG Brembo GT kits at no additional charge.

The TS20 is a OE grade mixed duty pad, similar to a Endless MX72 or Ferodo DS2500, and is designed to work well 0C-600C

Noise will always be present, but subsides significantly with proper bedding, and shim/grease.

What made you buy the "performance pads"?

Do you even need them for the driving you are doing?

Need the Right tool for the right job.
