on the emergency brake handle bracket you will see an adjustment nut on the end of the cable that comes from under the car attaching the cable to brake arm. you need to back the nut off till you have enough to take the rear wheels off to figure out what is causing the problem. common cause would be a cable is frozen with rust build up. release all cables from one and other to figure out which one is faulty.
The release handle is right above the parking brake pedal underneath the dashboard on left side.
If the cable is broken and parking/emergency brake is still ON, then they are rusted in place ! - Your emergency brake system needs urgent work.
AnswerOnce you put the car in "D" the brake will automatically release.If the brake does not release there is an emergency release, which is a small lever attached at the top of the parking brake pedal. Pull it up and the brake should release.
This is not a professional answer, but if it's anything like my 2001, the parking brake will release once you put the car into gear.
Underneath the dash on drivers side, just above the parking break release.
Put your foot on the brake, pu the car into drive and the parking break should disengage. if not, push on the parking break while holding the break in drive.
The parking brake on these vehicles are basically self-adjusting. Fully apply and release the hand parking brake lever 4-6 times to self-adjust.
There is no such thing as an "Emergency brake" in a vehicle. The PARKING BRAKE is the pedal to the far left against the edge of the driver's footwell. The handle above the pedal is the release.
Cables frozen and not releasing completely Parking brake not adjusted properly and dragging Service brakes not adjusted properly not allowing parking brake to release
check your cables first, if that's not the case you need to manually re-adjust your parking brakes
If it's all the way over on the left, it's the parking/emergency brake. You set and release the parking brake with this pedal. If it's right next to the brake, it's a clutch.
I don't know about Silverado trucks but all of the emergency (parking) brakes I'm familiar with use the brake cable to "pull" and hold the brake against the drum (or disk), so if the cable breaks you simply cannot apply the emergency brake. That is, it is automatically released if the the cable breaks.
