I replaced the rear pads on my car and now the brakes won't build pressure. Simply removed the caliper, put the new pads on, compressed the pison, put the calipers back on then bled the brakes all the way around. I figure it would have to be the brake master cylinder or the brake booster but I hear no type of leak coming from either to suggest that. Or should I not look into that too much? My friend and i went through an entire bottle of brake fluid bleeding the things and they still wont build pressure. The peddle got stiffer after the first brake (did the passenger rear then driver rear and then moved to the front in the same order) but then when I started my car the peddle went right to the floor loosy goosy. It would always go to the floor while bleeding them, but there was atleast some pressure there. I guess what I'm asking is if it could be anything other than the master cylinder or booster. I appreciate any insight because I'm at a loss.

You shouldn't have been able to just push the rear piston back in. It has to be twisted back in.

If you forced it, there may be an issue now...although I dont know how the F you could force that.

Check for leaks.

Also, you have to bleed with the car running. Try that.

 

pull the e brake up about 10-15 times and check brakes again, if you got no pressure still you [freak]ed up when bleeding

Yeah the piston turned as it went in. Really appreciate the help guys. Thanks a lot.
