I didn't properly bed in my brake pads. Now I have a bad vibration when I break hard. Checked rotors, no cracks ,they look good.
What is the best way to rebed them? I Was going to sand the pads
And Schottch Brite the rotors. Then rebed them.
Thanks. Tris

Can't speak to sanding, but this happened to me once when I had pad compounds that were not very compatible. After researching it I read that if you drive around and do some "cold" braking (normal street driving/braking) the friction will remove the uneven pad deposits that are causing the judder. I drove the car on some street trips and could feel it improving pretty quickly and in a short time the brakes had no vibration. When you reach that point I assume you could then try to re-bed your pads.

I occasionally get this (I drive my car to the track). I have found this goes away after one hard session, which will clear off the uneven deposits.

Sandpaper on both pads and rotors. Then clean them off with a can of brake clean.

I haved the same experience. The judder basically just goes away on its own after a bit.

I have had the same experience as Ben.

I would like to add that I cannot believe anyone would spend the time to take sandpaper to their discs. It is so boring and take forever compared to murdering the brakes 8-10 times. Brake pads are abrasive and will clean off the deposits. You don't need to get the Hawk blues or whatever JRitt @ Essex recommends to get the job done (though I am sure they work well).
Also, I never bed pads, other than stabbing the brakes 5-6 times to get the pads up to temp on my out lap. I'll give a medium heat cycle to discs, to avoid heat shock (cripples rotor life in my experience, particularly with the cheap blanks). NASCAR teams spend some bucks for that heat cycle on a brake dyno and I think they are on to something.

I had it really bad at LS. Felt like my car was coming apart. I have switched to other rotors (stock) and no more problem.

I can see uneven deposits on the rotors that vibrate.
