| I was wondering is pulsating under braking a sign of warped rotor? Or maybe bad rear drums. I'm hoping next weekend to overhaul my whole or a good part of my braking system. I'm talking rotors, pads, drums, shoes, brake lines and brake fluid. When I brake I can feel the car pulsate under braking(no it's not the ABS kicking in) I think the rotor are warped. Also it sounds like one of the disc brakes is dragging even after I let off the brake, could this be due to low fluid. I was wondering after the caliper squeezes the rotor and you let off the brake what makes the caliper release the rotor? Could the dragging be cuased by a bad seal in th caliper that isn't letting it move away far enough or could this be due to warping as well? Any info or insight would be great. I am going to paint eveything black too so I got the rebuild kit for the calipers. |

Someone can correct me if I'm wrong, since I've never rebuilt a caliper (I just replace them) - but I believe the brake fluid causes the piston(s) within the caliper to press the pads against the rotor.
When you let off the brakes, there is no more pressure and the piston(s) retract themselves.
And since you're rebuilding the entire system - did you remember the wheel cylinders for the rear, along with all the new springs and such? |

| Warped rotors will cause pedal shake. If your brakes are squealing its most likely because you need a pad change. |

| I'm not sure what the wheel cylinder is, also do you have to buy the spring separate from the shoes? As for the squealing there is none. The pad wore down to the metal bracket (the ones that hold the pad in the calipers), thats why I'm getting new rotors. I threw in some cheap pads to buy me time until I get new parts. |

If you take off the rear drums, you'll notice there's a bunch of springs in there (You'll also see the wheel cylinder - look in the Haynes manual for reference).
If you're doing a complete rebuild, as it sounds, it would be best to replace the springs as they are a wear part (Might never break on you - but if you're going all out, might as well replace them too). |
