Brake Pad Virgin - BMW Forum

I replaced the front brake pads and the sensor today. The car even stops.

How do I know that there isn't air in the line or something like that, in other words, how do I know I did it right?

Unless you opened the bleeder and let air draw back in, you are ok.

Just as a tip: You should never pry back the piston on an ABS car with out first opening the bleeder, doing so pushes old funky fluid into the ABS unit and often leads to it's early demise.

Hi sorry I’ve been away for the summer, but I’ve started racing single seatrs (not BMWs.)
Technically you should never push any brake piston back without opening the bleed nipple. This put back pressure on the master cylinder. I’ve never known it to cause a problem on BM’s but it does hurt other make. As long as you close the nipple as before the fluid stop running out you have to bleed the brake.

No ABS on my `84 325e. It seems good.

I am having problems getting the rear guide pins out though. I tried using a 1/4" hex and I think its a little small. Maybe a 3/8" or a 7mm??
