When disc brakes overheat there is usually one of three causes. The first is/are the rods or pins that the caliper slides back and forth on. These rods pull the caliper's outer pad into contact with the rotor. If these pins get sticky or corroded, they can cause pad overheating. The second problem is the caliper piston itself. They can develop rust ridge ring from exposure to ht elements and thus will not retract enough to break contact with the rotor. The third cause can be a collapsing brake hose. When the rubber hoses age, the can soften up inside. When applying the brakes, pressure will force the brake fluid to the caliper normally, but when the brakes are released, the hose can collapse, trapping the brake fluid in the caliper and not allowing the pad (s) to release. You need to disassemble and inspect the brake components to determine thew cause and take appropriate repair actions.

SOURCE: brake lock up

If you replaced the shoes (this would indicate you have rear drum brakes) you have to properly adjust the brakes. When you took them apart there would have been a part approx 2-3 inches in length with a star gear on it, you need to turn that star gear to make the adjuster shorter, when properly adjusted wheels should turn freely with a little bit of drag the shoes should just barely be contacting the drums.
If you replaced the pads (this would indicate you have rear disc brakes) were the sliders free and loose. The sliders are the metal tube the bolts run through to mount the caliper these work as adjuster as the pads wear down if these are frozen you are running your brakes as if your pads are still worn causing much friction with the new thicker pads. You can replace just the slides on the calipers but often it's easier to just replace the caliper and often not to much more expensive.

SOURCE: Front brakes lock up causing hot and smoking front brakes.

This sounds like the master cylinder isnt releasing pressure I would change master cylinder.

SOURCE: The right front brake drags and gets hot

When it drags, loosen the bleeder, if it releases, the hose is bad, if it does not release, the caliper is bad.

SOURCE: Replaced rear brake pads and

it is really common for the rear caliper slides to become stiff or frozen. The caliper should slide back and forth with little effort. If it doesn't than make sure the slides are free and lubricated.

If you had a difficult time installing the new pads into the bracket than that could also be the problem. The pads should fit into the bracket with little effort and feel loose once installed. If they don't than remove the shims and clean the rust from under them. Then reinstall the shims and see if the pads slide a little easier in the brackets.

Lastly make sure you didn't pinch or twist the rubber brake hoses.

Another thought is to remove the caliper from the bracket and try to spin the rotor/hub by hand. Maybe the e-brake shoes are causing the problem?

SOURCE: Just changed rear pads and

  • Well when you looked at the brake pads after your drive were the pads stuck to the rotor?
  • First thing to do is double check your pad and rotor installation.
  • Also check to make sure the right parts were installed.
  • When you pushed back the pistons on your calipers did they flow back nice and smooth? Did they wedge in and get stuck? This would make the pads drag.
  • If you used grease did you get some on the pad by accident? If this is the case it will burn off.

  • How is the car stopping for you? Properly? Do you hear any grinding while driving slow? While driving fast? Over heating rotors will turn a bluish stain. That is when it is really time to be worried.
  • If your brakes are not dragging then give some time for the pads to ware in.
  • If the piston is stuck forcing the pads against the rotor all the time then you need to replace the calipers.
  • Don't forget to bleed the lines afterword.

Regards, Tony

2002 Ford Excursion 7.3 4x4 rear brakes getting smoking hot. Noticed it on driver side first. Assumed the rotor was sticking, replaced it and the hose. Relaxed pads and found the pads on passenger side...

There are a number of issues that can cause overheating disc brakes. Disc brakes, when released, separate from the disc by the action of the rotor moving between them (since no rotor is perfectly true, there is a small about of wobble and it pushes the pads away from the rotor surface). Things that can cause this to go wrong are:

  1. Caliper pistons that have rust rings that cause sticking. This most often will happen right after or shortly after replacing old, work out pads with new ones. Because the caliper piston was extended out farther with the worn pads, its surface may get rusty. This rust can cause sticking when the piston is pushed back into the bore with the new, thicker pads.
  2. Caliper slide bolts will rust and get sticky, not allowing the caliper to release properly and re-center itself on the rotor. What you often see here is that one pad (inner or outer) is totally worn out and the other seems normal.
  3. Rusty brake lines/caliper internals can cause restrictions in the flow of brake fluid and hold pressure after the brake pedal is released.
It is highly recommended that whenever you change your brake pads, you replace the caliper slide bolts use a new brake hardware kit when reinstalling. The additional cost is almost always saved in longer brake pad life, and fewer complications.

Front brakes are smoking on drivers side and it starts to wobble

Your rubber brake line has capilaried, it blew out of the inner tube and stayed in the outer tube collapsing the inner tube and the brakes of course are stuck on. You have to replace the flex line, and bleed the brakes, quite common problem. Hope this helps.

Frt lft brake stuck and can I release it at the side of the road and get it home?

do you have a screwdriver? Take wheel off. Put screwdriver thru side of caliper between the inner brake pad and the rotor. Use a hammer or something to drive the blade in between and then gently pry the caliper piston back into the cylinder. OK?

My brakes are taking too long to make the car stop, i have to push my foot on the brakes hard for it to slow down, then my car started smoking in the back..what can cause this?

very scary, but first you would need to see how much brake fliud is in the resv. how low are the pads,but that probably wont be the problem. easy way to check is with the car in part and running, press down on the padel to see it will stay at one point when depressed. if it holds but slowly lowers it might be a sign of a leak at one or more brake lines or a bad master cylinder

Replaced rear rotors and pads on 1999 4wd silverado, they now get burning hot , greased pins ok, whats wrong ??

make sure the pads move very freely inside the caliper bridge rust can build up and bind pads causing excess friction. never hurts to double check the parts purchased are the correct application.

Your brake caliper may be partially seized or the pads are seized on the mounting bracket.
