alright, recently i got in a car accident and anhillated my brakes. unfortuatly i had to drive 2 hours home from the site. all i heard was squealing when i was rolling and grinding and my car shaking when braking. i got home and checked my pads and they were shot, im talking no pad, metal against metal [some chunks of pad here and there] so i replaced the pads and i still had no front brakes.

i went and picked up to calipers from autozone [i have no moeny so i got the cheapest] still no front brakes. i bleed the brake lines correctly and everything. i know i need new rotors but they wouldnt make this problem. anything im doing wrong? ive bleed the brakes, changed the calipers, got new pads, and added new brake fluid.

when i slam on my brakes it take forever to stop and if i hit them hard enough can hear my back tires squeal from the back brakes.

i have single piston fronts
and drum backs.

all info is apprectited

 

Possibly a master cylinder problem
