I have a 1990 hyundai excel,how can i adjust the emergency brakes to hold more when i pull up the handle?

Over here we call it a parking brake - hardly any of our cars are autos.

Parking brakes usually connect to the rear disc brake calipers but some manufacturers use a small drum brake in the disc centre for parking purposes due to the complexity of the caliper with integral parking brake.

When adjusting a parking brake it is important in most designs for the cable to be adjusted only to remove any free play without moving the caliper levers from the backstops and then if the parking brake lever or pedal travel is excessive it must be because of wear or other faults. Sometimes that basic requirement must be taken with a pinch or two of "experienced" salt...

Ford have a self adjusting parking brake I have experience of. A spring within the system preloads the cable eliminating all slack in the cable so the cable moves the caliper levers from the first. The main problem with the system is the preload spring is sometimes strong enough to overcome the resistance of the caliper spring and cause a binding brake. No manual adjustment was provided.
In that case I find fabricating and fitting brackets to anchor additional return springs to the calipers is a must.

The brakelight fuse and the switch on the pedal is only for the brake lights. It should have no effect on the dash brake light. That light is to alert you that a problem exists in your braking system, not the brake lights. I think you will have to pull off the rear drums and investigate why they are locking up. Check for a leaking brake wheel cylinder that may have contaminated the brake shoes, causing them to grab and lock up. Are the shoes in good shape? Also, check the operation of the emergency brake. Maybe it is not releasing fully. The emergency brake can be adjusted on the cables somewhere underneath the truck, probably at the equalizer (where the cable for the emergency brake splits to both sides of the truck). The adjusting nut will have a lock nut tight against it to hold the adjustment. Loosen the lock nut, then turn the adjusting nut one way to loosen the cable, and the other way to tighten up the cable. You might want to loosen it up and see if that has any effect, and then tighten it once you have fixed the problem. The adjustment would be about right when the emergency brake handle or pedal locks up the rear brakes when it is depressed about halfway to nearly fully depressed.
Hope this helps you out, and good luck.

pull the emegency brake pedal back with your hand manually while holding the release handle and light should go off. the spring return on your emergency brake pedal may just need adjustment. try this 1st before you do anything else please, it may be a simple thing. hope this helps and thank you for choosing fixya.com

Adjustment is under the console.

check to see if broken if so replace also check rear brake life and try adjusting the cable tighter

This will require you to take the center console out for a better view and to more easily access and adjust the hand brake.

the book is correct it is under the hand brake itself and very easy to adjust once you get the console out of the way its held in by screws and you will have to take it totaly out.

you need two wrenches to adjust the parking brake and that's it.. remember to leave it in the down position when adjusting it and pull it up after about every 3 full turns turns just to check to see how tight you have it. you don't want to over tighten it
the emergency brake will be on all the time and wear out the brake pads. this sounds harder than it really is. the hardest part of the whole thing is getting the console out of the way once that is done you will be able to see how its done

Use a vise grips.

BELOW OR NEXT TO E BRAKE HANDLE NEED A 10 MM DEEP SOCKET,PULL UP HANDLE TAKE A FLASH LIGHT,ADJUSTER BOLT RUN NUT DOWN

look under the front of the rubber boot that covers the bottom of the park brake handle, u will see a nut on the end of the park brake cable, tighten it until u reach the proper adjustment.

either need to adjust the emergency brake cable or replace your rear pads
