first post in a long time...I need some help or suggestions with my Brembo BBK. When i first installed them, used from Ryan(Lexus84), they were working perfectly (quiet and could stop on a dime!) After a while, i had to install replacement pads from Brembo.

There's still plenty of meat left on the pads, i guess when i installled the pads, i didnt lube or grease it, i jus took out the old, and put in the new, dont deal. But through barely aggressive driving in the summer, the brakes will start to make that very high pitched sqeal when coming to a stop, so i took the pads out and greased and lubed the pad backing and bolts. But now in the winter, the brembos sqeak and sqeal jus bout everytime i drive the car. I cant find a pattern as to when the sqeak. I thought it was because the brakes were very hot during the summer, they would squeal, but now even in the winter, the squeak and squeal, at almost anything.


Also, anyone know any BBKs with front AND rear setups. I think stoptech's make em for the front and back, I was hoping for 6-piston up front and 4-piston in back, but im afriad that might be too much for this car and might throw off the brake balance. But does anyone know of any other manufacturer with both front and back? I called Brembo, a specialist told me the reason Brembo's dont make BBK for the back is because they couldnt find a sensitive system enough and the wheels would always lock up.

Any help would be great.

Rotors sound glazed. spray some brake cleaner all over the rotors to help break the pad deposits loose then go beat the crap out of your brakes. and i mean BEAT on them. do about 5-6 60-0 stops with the pedal to the floor as quickly as you can. then try 1-2 80-0 stops. That should break the glazing loose. We see it all the time at my work when people just do pad slaps. You are supposed to do a minimal rotor resurfacing if you change pads but many people neglect to do this. Drilled and slotted rotors CAN be turned by the way. You just have to work VERY slowly with the lathe. I've turned my slotted Brembo rotors twice myself and have no problems.

Tom, i wanna give your suggestion a try, that sounds like a relatively simples solution. However, im not sure that spraying brake cleaner on the on or around the calipers is such a good idea, being that the clearner can eat or damage the paint on the bbk calipers.

What is turning the rotors?

when you turn the rotors you use a brake lathe. Its a machine that has a shaft that comes out of it. you put the rotor on the shaft and tighten it down. Then you run the two cutting blades on each side of the rotor. You cut the surface of the rotor very little. Its used alot when your rotors are warped it will balance them out.

That wasn't a very good description but you get the idea. It can be down at any shop that does brakes.

what to do? apparently my discs are glazed. and i cant get adequet bite from the pads when the brakes are cold. I want to try Tom's suggestion and spray them with brake cleaner and beat on them, but I'm afraid the chemicals in the brake cleaner will ruin the paint on the calipers. Any suggestions?

just take them off and go get them turned at a shop. Like a tire shop that does brakes. Thats the best way and will cost you about $20

Your calipers should be powdercoated and brake cleaner should not harm this finish. If it were your backyard brake caliper DIY finish, this may be a concern. Since the brake cleaner will evaporate quickly, you can take both wheels off and try to remove the glazing while rotating the disc if you are concerned. A lathe is really going to be the most reasonable way to get rid of it.

Ill bring this back from acouple months ago..

When ever you swap out to new pads you need your rotors recut. So that your end result will be flat on flat contact. It doesnt make a big deal on your run of the mill brake set up. Yet big brakes are another story. As there is more contact surface to worry about. You dont need lube/Brake Quiet/ Or any other spray.

I went through this ordeal when i got my Evo. I was so used to slapping in pads on my Eclipse GSX that i didnt even think about this and it was asked non stop on the Evo forums when the car first came out. Everyone thought it was there pads as well as not using lube.

Just some FYI.. i found that the Project Mu pads were the best over all on ride as well DD & pocket price.

Even for the Upgraded Supra TT kit on the IS..
