I installed Carbotech XP8 front/rear, and I can't get rid of the freight train squeal...
I try bedding them on the street, but it didn't seem possible with the OEM tires to put enough pressure without locking the wheels.
I then did a track day. It was possible to bed the brake properly on track, and after that, the squealing was a lot less (seemed random, about 1 out of 4 brake press and weaker). But after 4 days of normal DD, the heavy squeal is back on each brake press whether light or hard press.
What do you think would help? I was thinking of bevelling the edges of the pads. Could that help? I could also try to put more brake grease (I used Permatex silicone-ceramic extreme, but didn't put a lot because I was afraid it would drip on the rotor with the track heat).
I could also remove the OEM backing plate/shim that I kept, but I was under the impression backing plates should help reduce noise, not create more.
Any other solution?
Those brake pads are awesome on the track, but unbearable on the street...
