Could be many things, but I would check if self adjuster screw is frozen or rusted, self adjuster cable is broken, or emergency brake cables are frozen.
How do I adjust my emergency brakes on my 1999 ford expidition?
I'm going to bet they are drum style brakes. I have a 1999 Luminia, and they are drums on it.
Yes, of course you can adjust the rear drum brakes. They should be self adjusting. Every time you back up and apply the brakes they should adjust themselves. If that is not working, look for a small rubber plug on the back of the backing plate. Remove that plug and with a brake adjustment tool, you can adjust the brakes. Search Google for the proper procedure to adjust drum brakes.
Same as the Caravan...
Our 1999 Chevy Lumina car - 3.1L at 150k miles has been very reliable, to date replaced alternator, reg tune up items (belt, hoses, ect...) and brakes.
First make sure that service brakes are adjusted properly Adjustment is located under the vehicle at the junction of the cables Set brake to 3 clicks and tighten adjuster so vehicle is "held" at that point
Are the rear disc brakes or rear drum brakes? If they are disc brakes, ther is no adjustment. If they are drum brakes, you adjust them by backing up and hitting the brakes. Do it in an empty parking lot. If they are drum style brakes, simply put the van in reverse, and accelerate backwards about 10 feet, and jam on the brakes.. repeat a few times and the auto-adjusters will tension the shoes against the drum properly accounting for the pads thickness, or lack thereof. If they are disc brakes, you have no capability to adjust them without removing the wheels, the calipers, and "shimming" the pads so they are thicker inside the caliper. If your pads are to thick, then you have the wrong pads, and if they are to thin to shim out, and safely stay inside the caliper, then yours pads are worn and needing replacement.
Where do you find a knock sensor on 1999 Chevy lumina
Yes
Yes
Hopefully you mean a 1992 Lumina, and yes, most starters are standard.
not likely!! problem is probably adjusters stuck !!on rear brakes,if the adjusters were not stuck then whenever you back up they should adjust them selves.
