A stock emergency brake, on a Chevrolet truck, can be released by manually disengaging the emergency brake. This can be accomplished by loosening the tension nut on the brake.
Run the truck backwards to about 10 Mph, hit you brakes very hard. This will adjust your brakes in general.
if you want to adjust the emergency brake tension on a 1985 chevy scottsdale 10, you would have to get under the truck and take a look at your brakes. it may be that you would have to also look under the hood or ask a mechanic frien for assistance.
The only way you can completely turn off the headlights is to push in the emergency brake slightly, then start the truck and leave the emergency brake on the slightest setting, and the running lights will stay off. Obviously the brakes will be slightly engaged, but you can adjust the emergency brake so the first click doesn't engage the brakes.
The 1990 K1500 pickup truck parking brake is equipped with a adjustment bolt. Turn the adjustment bolt in or out to adjust the parking brake.
If the truck has disk brakes in the back then you have to adjust the emergency brake cable underneath the vehicle by loosening the outer lock nut then tightening the adjuster nut and then you re-tighten the outer lock nut down to the adjuster nut.
The adjustment is on the cable running along the outside of the left frame rail, it is located about even with the door. There is a threaded rod that you screw in or out to adjust it. You will have to spray it WD40 or someting like that to get it to turn if it has never been adjusted before.
Sometime the brake shoes will rust or freeze to the drum. TAke it to a garage.
You don't adjust the clutch brake itself - that gets replaced. If you're trying to adjust the clutch itself, see the related question "how do you adjust a clutch on a Class 7 or 8 truck"... I've spelled it out there already
I'm thinking about what you said, and I release probably you don't have emergency brake on, it could be something broken on the rear brake hardware, So you have to pull your tires off and check the brake springs and check emergency brake cables under the truck,
if its on a car or truck (brake caliper) it is how the emergency brake works, usually on the rear, it has a cable that turns the cylinder inside the caliper
