The emergency brake seems to tighten the rear brakes (this happened after the brakes were replaced with new ones) Now the brake lights stopped working (all 3 at the same time). The fuse is good and the switch was replaced and still no lights. Is there a relay I could try to replace? Any other suggestions?
Check for 12 volts at the light sockets, especially the one at the top. If it has a bad connection it will cause you to have no brake lights at all.. Good luck and I hope this helps you out. Doogie1948.

i wonder if you mean abs light i f so loosen and re tighten .often no contact makes the abs light come on .other wise release emergency brake perhaps the peddle got pushes a couple of clicks enough to make light come on but not enough to look like it is applied.try emergency brake first push then release with handle.you wouldnt beleive how many people this happenes to .
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.
this sounds like a brake issue and usually the emergency brake..lift rear of car to see if the wheels will turn if one does turn .remove tire and loosen brake bleeder screw to see if you can release brake pressure.after that tighten bleeder screw and remove brake drum.if the wheel has disc brakes you will need to remove emergency brake cable if it is too tight to remove you need a new one anyway so take a hack saw and cut the cable at the brake unit
The parking brake problem could have started the problem you are having in the coldest weather. Some may disagree but look carefully at the emergency cable parts. The cable is suppose to equalize the pressure to each wheel. Some of the rear brakes are made to automatically adjust the SERVICE brakes when you use the emergency brakes. Therefore if the emergency brakes are not automatically tightening the SERVICE brakes, you can get excessive play in the "star" wheel and the flat rod that spans both shoes.
This means that the brake cylinder pistons can travel
too far in the cylinder and are trying to bridge the gap. The hold-down pins and springs are loose too.
You can also have moisture in the rear brake lines and the "Brake warning light" is coming on because the proportioning valve is not returning to center in the lines. You should have a power bleed job with a cleaner run through the system and new fluid. That may fix the problem without checking the adjustment of the rear brakes.
if you need to tighten the cable under the vehicle you will find where the single cable from the front connects to the two rear to tighten set the emergency brake six to seven clicks and tighten nut until the brakes catch. if you need to adjust the actually brakes in the drum set the ebrake the same setting find the little rubber plug on the backing plate remove get a small flat head screw driver and flash light find the little gear inside use the screwdriver to turn will only go one way turn the gear until brakes grab and wheel can't be turned.
brake seem to tighten when applied? out of adjustment? rear disk or drum brakes? if disk it might be built into the caliper like mine and the calipers can go bad so they wont set or is drums shoes worn or out of adjustment?
