    I've had this same problem.  My right rear brake has been locking up and overheating (heating up the entire wheel surface too) and even smoking a fair amount.  I removed the caliper, and pushed the pistons back in and put the pads back in place and placed the caliper back in place.  It locked up less than 5 miles later.  So now I guess the most obvious thing is to replace that caliper.  I asked earlier at Auto Zone and they have it for $70, that's after I give them the old caliper, if not then they charge an additional core fee.

You think your caliper just froze up? those arnt very expensive usually, i would just take off the caliper and see how hard it is to press in i was looking at the wiring diagram for your vehical there is a front left front right and a rear wheel speed sensor. it looks like there is no way the abs could lock up one rear, and besides the abs is to stop the wheels from locking up not to actually lock them up, anyways im almost positive its either someone left your brake on and didnt notice which wouldnot explain only one wheel locking up, your brake cable is unajusted on that side which would make it do this all the time, or that your caliper was just freezing up on that side which is probably what it was, you should be able to notice the drag, i would replace caliper and call it a day. make sure your caliper slides are not locked up also, that would cause only one side of your pad to contact that roter and overheat it quicker, so these last two options are the only plausible solutions i can come up with, if you take that caliper off, try to move the slides that the piston have that the bolts go through to the caliper mounts. make sure those are free floating first, then i would think of replacing the caliper if it goes in unsmoothly. good luck brother any other problems or need any other help give me a shout, take care

Brakes went out,master cylinder is dry. filled the master cylinder pumped brakes and bled rear drivers side


    If there is a substantial fluid eruption, there are air bubbles still trapped in the system. You must repeat the bleeding procedure to remove that air. A modest disturbance in the fluid returning to the reservoir indicates a properly bled brakesystem.

What is DSTC


http://www.youtube.com/watch?v=G8mniiBdHik Here's a short clip that explains what it is.
And a text found online
DSTC
Dynamic Stability and Traction Control (DSTC) is an even more sophisticated stability system to improve active safety by also intervening and counteracting any tendency to skid.

If the car makes a sudden movement and loses its directional line, or enters a corner too fast and the rear end starts to turn the car inwards, DSTC gently returns it to the right line. This is done by applying the brakes on one or more wheels.

DSTC works through the ABS system, which has been further developed.

A number of yaw angle sensors monitor the rotational speed of all four wheels, the steering wheel angle and the directional behaviour of the car.

The DSTC processor receives the signals and compares the actual behaviour of the car with the desired behaviour. Any deviation from the norm, such as the rear wheels starting to break away, and the system intervenes and makes corrections, activating the brakes on the wheel that will bring the car back in line. If necessary, the system also reduces engine torque, like STC.

In a way, it would be true to say that DSTC is able to compensate for the driver's mistakes up to a certain point, as it counteracts and prevents skidding when the driver has already started to lose control.

The system is particularly effective if the driver has to brake hard and steer away at the same time, like the well-known elk test. The system counteracts any tendencies to skid and returns the car to its original course.

DSTC works through the ABS system which has been further developed to incorporate this system. In addition to more relief valves and a more powerful microprocessor, a brake reinforcement unit with electronic activation, sensors for side acceleration, yaw rate and steering wheel angle have been added.
Hope it helps.

1998 chevy express van 3500 front brakes and rear are new, front calipers are new but ABS light on dash is on, the front brakes smoke after a little while of driving. Thanks Joe


I'd first make sure the new pads are the correct size. Doesn't happen very often but maybe the parts person gave you the wrong size pads ( for the smoking problem). As for the ABS light, most newer cars will throw out codes if you wait too long to change them out, I would contact a chevy dealer or search online about reseting the code (light).

ABS AND BRAKE LIGHT 99 1500 RAM TRUCK JUST CAME ON WHAT COULD BE THE PROBLEM SEEMS TO BE BRAKING OK


Check brake fluid, also could be wheel speed sensor,try washing the wheels out real good and be sure to look behind wheel to see if any wires are hanging loose.
If not you need to have brake system checked

Rear ABS Light/Rear brakes drag sometimes


The only moving parts on brake's are caliper's and master cylinder.The rest are just pipe's. Dosent sound like the master cylinder as the two back brakes should lock not one. It still sounds like caliper's. Can you be sure they have changed them If it were mine I would get someone independent to check they have done the work they say they done.

First try rotating the tires to the rear. Does it go away? If you apply the brakes does it pull to the left? Could be a draging caliper or the slides may be hanging up.

Vehicle shakes


I doubt it. You'd have an ABS light on. All wheel are warm to scalding hot after even light driving. ABS systems do not apply brakes. They unapply them. They simply cut the fluid to one of the wheels / axle sets of brakes. (Newer stability control systems use the brakes) In your case. The ABS can deactivate either front wheel independantly, or the both the rear brakes together. You can take the wheel off & flip the pad & piston up to check it if you want, but I wouldn't think it was the brake dragging at the top of my list, no.
