Talking Changed pads/rotors on 740i

Just want to thank the people on this forum. Reading your posts and links, I was able to change my rotors and pads with no surprises - they work too. It saved me about 700 bucks and was actually fun.

Some of my observations as a newbie that may help someone else someday:

1) Reading the threads on the rotor allen bolt stripping scared the hell out of me, so I sprayed it with PB as soon as I got the wheel off. When it came time to remove the rotor: very easy.

2) The upper caliper bolt is very close to the brake line making it a pain to get a ratchet in there. Get a 2.5-5" extension and its no problem.

3) The bolts on the caliper retaining bracket (I'm unsure if this is what it is called) are on very, very tight. I had to rig an extension bar to my ratchet to loosen them. Have a breaker bar handy.

4) I didn't use the sensor that I bought.

Some questions:

1) I did not use anti-squeak. The guys at bavauto said it was unnecessary. I was always wondering though, how does applying a substance to the back of the pads, which are not involved in producing friction during the braking process, supposed to stop squeaking on the other side?

2) I called bavauto to asl about bedding the pads and the guy told me not to worry, just drive normally. I went to www.pagidusa.com and they have a "Brake Pad bedding Procedure" they recommend you follow.

Thanks again.

Oh yeah, what do you guys do with the old rotors?

Bear is an unknown quantity at this point
Anti-Squeal Lube

The anti-squeal lube keeps the back of the pads (if vibrating when braking) from metal to metal contact that can give the squealing sound, it has nothing to do with the friction side.
