Question? How did you end up cooking your brakes in the first place? Did you figure that out.......

^ +1. That would be helpful. Sorry to here you are having trouble.

Another question? When you finished installing new pads, new rotors, & wear sensors....
Why did you decide to bleed the brakes? Was it because the brake peadal was low & if so, this why maybe you had no pressure to rear brakes.......if your brake peadal did not come up after bleeding......that means the brake master cylinder is bad.......there is a piston inside the master cylinder with O-rings (seals) that push the brake fluid out to the front & rear brake calipers......when the seals go bad.......the fluid leaks past them & right back into the master cylinder resivoir & not to the brake calipers....can you explain exactly what you have done?

Not to hijack this poor guy's thread, but do you bleed the lines before you put in new pads and rotors? Is this a tough job, replacing rotors and pads on an e34, or can a mechanically inclined guy doo it in his garage within 1-2 hours. Pricewise, the parts are going to cost me 150 and my labor vs 495 at the bmw indy for my rear brakes. Advice?

+1 on the bad master cylinder idea.

Its a diy job if your a mechanically minded, I can do mine in less than an hour easily....there is no need to bleed the brakes for a rotor/disc or pad change.

[carguy13]

damn, an hour...that's good time.

i took me at least 2 hours to get my tires off...

well they were rusted on there so bad the rust would support the weight of the entire car...

[coolvegase34]

Thanks marti5 for the info. I have no rust or imperfections on my ride. The only problem with getting the tires off is they are machine tightened and I will be man-torquing them off.

while driving home saw smoke from rear pulled over and saw thatmy rear brake rotors were rather red hot and throwing out a little fire.able to squash flames and let cool.then embaressing towed home.have been trying to bleed but no good,blew outline many times by diconecting hard lines and using air compressor.get flow from one line to passenger side on the abs module,not sure what it is ,but all the lines go to it.so now i'm stuck on what to do.using bav auto bleeder but doesn't seem to push threw.need help, want my car back,tired of daughters ford escape.

The back brakes seem to be stuck as if constantly braking I think. What's the condition of the parking brake and its cable?
