I can change brakes, (pads) on american cars, but there is a sensor that needs to be replaced on beamers too? Can I do it with out bleeding them? Should I just bring it to a mechanic? CAN ANY OF YOU FELLOW BMW LOVERS PLEASE HELP!! ghead
Its so easy..theres only 2 nuts holding the calipers. I think 15 or 17. Just loosen them two and it'll fall out. My left brakes had the sensor,just be sure not to let the heavy caliper drop and yank the sensor off. the sensor can be removed very easily and put back on. etc. the rightside of my car didn't have a sensor just the left drivers... I didn't have to bleed nothing. I use a rubber part of the wrench or whatever I can use to push/pry the cylinder back in order to put new pads on and put onto the rotor....Sorry kinda confusing but I'm at work....The job took me about 25mins each side...very easy to do...saved $$$$
The sensor tells you when the brake pad is low. It is pretty meaningless since the pads are so easy to inspect anyway. Each wheel has one. The trick is to replace, rather lose, the very tiny spring clip that holds the sensor in place.
If the clip is gone, I don't know where you get one. My dealer said there was no part# for it. I just bought a '95 318i with 115,000 miles. The previous owner lost one of the clips at their brake pad replacement job.
Brakes are a breeze to replace. Just remember that before you compress the piston in to accomodate the new pads, open up the brake reservoir and remove some brake fluid or it will spill out depending on the level. Also, if you have ABS, as you are compressing the piston, open up the brake bleeder so you won't chance having even the smallest bit of contamination find its way into the the ABS pump system or you may find yourself with the ABS light on!
