So, i put new pads and rotors on my rear, and my front pads/rotors are fine. After doing the work i noticed less stopping power, confused i bled all the lines. Didn't solve my issue. I can't even lock up the brakes to get ABS to kick in...any suggestions? Bad master cylinder?

 

I know you said you bled the brakes but you might still have an air bubble in the line (easy solution), you could have loosened the brake lines when you pulled the brakes apart (remote possiblity and pain to fix), or you could have a bad master cylinder like you said already. But I dont see why your M.C. would work fine before the work and suddenly break after. I would check all your brakes lines again, and re-bleed the lines before pulling the M.C.

Good luck,
Matthew

 

Well, one thing that helps me is I work at NAPA, so i get a discount of cost +5%...a new MC costs me about $30 lol. But like i said before, i only messed with the rear rotors and pads....so my front was fine...but i bled them anyways with a line...i am just so confused what is going on...lol.
