x5 e70 brake problem...need help pls
I'm a new member & hello to all.
I need help please. I just replaced my '07 X5 front pads and warning sensor. I thought my work went well and everything should be ok (as I have done same thing +replace rotor on my e46). But after new pads have been installed...I noticed the pedal has a soft feel and very weak brake, and even worse, the pedal is slowly going all the way down the floor. I resorted to bleeding the front only (although I didn't think I needed to if just replacing pads), but did not fix the problem.
Any suggestions what I might have missed or done wrong? Fluid level stays the same, and I don't see any exterior leak. Although I don't know for sure, I'm not yet suspecting a master cylinder problem for now, as I had no other problems before replacing the front pads (the pedal was firm even with the old worn pads). I replaced the pads (using OEM parts) due only to the brake warning light coming on.
I really would appreciate much any help or input. Thanks so much in advance!
