Car pulls to right on braking

[mjorgensen]

The brake pedal feels completely normal, engages up top and stays very firm. I would say there is no air in the system. On the way home last night I must have gone from 60mph down to almost stopped (anti-lock engaged) about a dozen times. The left front just doesn't seem to want to bed properly. The rotor has black streaks, and makes a grinding sound.

From Brakeman web page: With any compound, if you observe black streaking on the rotors or poor performance, the pads were not properly bedded and need higher temperatures.

I should generate enough heat coming into turn 12 at CoTA this weekend!

You should NEVER let the ABS engage when bedding pads, they need to smoothly transfer pad compound to the rotor and rapidly locking and unlocking pads on the hot rotor will cause all kinds of problems.

Oh, now you tell me . Makes sense I guess. So, please tell me what the proper procedure is. Do I go 100 to zero but no ABS? JonB suggests there has to be air in the system and that's why the left front isn't applying enough force to properly bed.

I have no idea how there could possibly be any air in the system. It has been bled 3 times at this point, and the last two times showed zero air in the system when bleeding and nothing but clean fresh fluid. Did you go out and try to re bed them? I really think that front drivers pad isn't properly bedded yet .

Agree on all counts bro. Didn't get a chance today.

Maybe try something like this if you can't seem to get them to bed properly?

If there is uneven pad transfer on the rotors now it could be best to use a 3M sanding disc to clean off the surface of the rotors first or you can try the re-bedding again by doing;

"If rotors were previously bedded using a different manufacturer’s brake pads; then it is strongly recommended that the used discs (rotors) be reconditioned/turned and meet minimum specification requirements."

Here is some great advice to follow and Q&A;
