If you have drums for the rear brakes then have the drums check for out of round. This occurs when the drums are hot and the hand brake is pulled on tight and the brakes cool down adopting the shape of the shoes.

SOURCE: 2002 GMC Sierra 1500 rear brakes

Hi joelalthomas, if they replaced your brakes and you never even made it home they had better warranty the work and as for the "it was a common problem on 2002-2004 trucks" well check for Chevy recalls as this is a safety issue that would have been corrected at no expense to the vehicle owner, do a little more research my friend and let me know what happens, I will check around a little as well in the meantime I would find a new garage.Do not pay any more as you said your brakes worked fine until they worked on it good luck to you As for your 4x4 did you look at the left side when you did the right side? and were they bled off properly? you can visually check to see if the calipers are functioning

More likely to be a rear end issue. If the brakes have been checked I would have your rear end checked. Could turn into a very dangerous situation.

My drivers side rear tire locked up while driving in my 84 Nissan Datsun pulsar NC what's wrong


'84 ...*lotsa* miles on it ....like 450K plus if you drive the "normal" 15K/year. First, and most likely, thing that comes to mind is the wheel bearing has seized. Since this is a front wheel drive car, there are sealed roller bearings for the rear wheel hubs. At 450K on the odometer there are *lots* of components that have reached or exceeded their normal service life. I would suspect the left rear sealed wheel bearing is one of them ...followed closely by the right rear wheel bearing. If it's the bearing? Get them both done.

Back tire locking up wondering if the emergency brake cable doing this


It could be the cable, but usually it's a bad brake caliper, if you have 4 wheel disc brakes. If you have rear drum brakes, the brake shoe retainers could be bent or shoes are adjusted too tight to the drum. Hope this helps :)

Drivers side rear brake locks up on severe braking, then releases and I have no brakes


If you are dealing with ABS brakes you probably have a bad wheel cylinder on that wheel and air in the line. Replace the wheel cylinder and bleed the system.

ABS brake module sounds like a motor running and won't stop unless battery is disconnected. what is fix?


I would pull the fuse for the ABS hydraulic pump and then put it back in and see what happens. Don't ever recall a pump running. Dealer may need to hook up scan tool for diagnostic fault codes, DTCs.



Principles of Operation
The ABS control module receives wheel speed readings from both front wheel speed sensors and the rear differential speed sensor, and processes this information to determine if an ABS event is necessary. The wheel speed sensor electrically senses each tooth of the ABS sensor indicators as it passes through the wheel speed sensor's magnetic field.
The ABS control module continuously monitors and compares the rotational speed of each wheel speed sensor indicator and, when it detects an impending wheel lock, modulates brake pressure to the appropriate brake caliper(s). This is accomplished by triggering the hydraulic control unit (HCU) to open and close the appropriate solenoid valves. Once the affected wheel returns to normal speed, the ABS control module returns the solenoid valves to their normal position, and normal (base) braking resumes.
The ABS control module is self-monitoring. When the ignition switch is turned to the RUN position, the ABS control module will do a preliminary electrical check, and at approximately 20 km/h (12 mph), the pump motor is turned on for approximately one-half second. Any malfunction of the ABS system will cause the ABS to shut off; normal power assisted braking, however, remains.
Inspection and Verification — Scan Tool Communications Check
  1. Verify the customer concern by carrying out the Drive Cycle Test.
  1. Visually inspect for obvious signs of mechanical and electrical damage.


Visual Inspection Chart Mechanical Electrical
  • Parking brake cable
  • Tire pressure
  • Tire size or mismatched tires
  • Blown fuse
  • Central junction box (CJB):
    • fuse 23 (10A)
  • Battery junction box
    • fuse 102 (50A)
  • Connectors or connections
  • Ground integrity
  • Harness routing
  • Wire chafing
  • Circuitry open/shorted

Anti-Lock Control The four-wheel anti-lock brake system (4WABS) consists of the following components:
  • Anti-lock brake control module (2C265)
  • Front anti-lock brake sensor (2C204)
  • Front anti-lock brake sensor indicator (2C182)
  • Hydraulic control unit (2C219)
  • Rear anti-lock brake sensor (2C190)
  • Rear anti-lock brake sensor indicator (2C189)
  • Yellow ABS warning indicator

Rear wheels not spinning. Front wheels spin when in 4 drive.


Hi First of all check the adjustment on the rear wheel thats sticking sometimes the brake pad comes away from the metal it is fixed to this maybe the case on your vehicle, the make & year of vehicle would help further but I a sure you got something to check now. Please leave me feedback, Malcolm Campbell.
