disc brake problem

[patsublett]

I put new pads on the front, they drag so bad that my car gets hot if I drive too far. If I put a "C" clamp on them and push the piston in, there is plenty of clearence. Any suggestions? I don't know if I should keep driving or if there is something wrong.

There is definately something wrong. Did you clean up and grease the slides where the two halves of the caliper slide by each other? I've seen brakes hang up if that isn't done.

Replace the flexible hoses if all else is OK. they plug up inside. When you put pressure on it goes through, but when released, they hold pads tight.

Take the calipers back off. Remove the bolts from the calipers. Clean and and lubricate the bolts. (The silicone lube is available at your auto parts store.) Make sure that the calipers slide freely on the bolts. Reinstall everything and you should be good to go.

I agree with Dave, change the flexible hoses. Check to see if both sides are getting hot. If only one side, then change that sides hose. I had a Chrysler New Yorker where the hose looked good, but the insides were shot and would not allow the fluid to go back, thus keeping enough pressure on the pads to slightly apply the brakes at all times and create a lot of heat. Changed the hose and the problem was solved. This also caused that sides pads to wear much quicker than the other side.

I would bet that the calipers are hanging up either on the slides or more than likely the pucks in the caliper.

The bolts on my pickup had to be cleaned plus the mount holes were filled with rust and had to be cleaned with a tap.Pulling the dirty bolts out thru threaded holes filled them with rust.Neighbor just paid 700.00 on a sticky disc problem.Hope you can fix it yourself..I think disc brakes are trash,they seem to heat the rotors full time.Reduced lining area, fully exposed to road salt and sand.Fancy wheels covered with pad dust are impossible to keep clean.

a quick way to check the hoses to see if they are bad, have someone press the brake pedal down and then release it, then crack the bleeder open on the caliper, if it squirts a little fluid out, change the lines for sure.

The square-cut o-ring may have debris built up behind it causing the piston to not retract on it's own. Remove the entire brake assembly and carefully remove the pistons, clean out the groove, replace the o-ring, lubricate all moving parts with brake lube, re-install, bleed the system, and see if that solves the problem.
