SOURCE: 1998 gmc sierra brake lights

did u check that they not burn?if not you should Check the wires going into the steering column if you don't have separate turn signal lights and brake lights because if they use the same bulb then the turn signal may be bad. If I remember correctly that particular car doesn't work this way, but I include it just in case.

The first problem that I see is.....

You got screwed, the rear brake shoes and the parking brake shoes and the same thing. The parking brake uses your back brake pads to set the brake.


Sorry man

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

SOURCE: how to adjust parking brake on a GMC Sierra 2500

The adjuster is just like on a car with drum brakes. It can be adjusted with the wheels still on the truck, but if yours is out enough that it doesn't work, an inspection is warranted. Axle seal failure is common and will soak the shoes.

Jacked both rear wheels off ground, and while slowly spinning wheel, tighten the star-wheel adjuster until you just hear and feel brake drums rubbing, then loosened slightly.
There's a plastic dust cover about 1/4" X 1" that you remove, and use a drum brake adjuster tool.

The driverside access hole is below axle, easily accessable. To tighten driver side rear parking brake, turn star-wheel adjuster down.


The passengerside access hole is found above axle, and difficult to see. Removed pass side wheel and used an inspection mirror.
To tighten passenger side rear parking brake, turn star-wheel adjuster up.

Good luck and hope this helps. Oh and the other thing to is that if you do smell axle fluid around the wheels and see oil leaking from the drum area. Then you have a axle wheel seal and or bearing gone bad too.

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 :)
