The red brake warning light on. Park brake not causing problem. Fluid level sensor not causing problem. Is there a brake proportioning valve that would cause the light to illuminate? If so, where is it? It is an electrical problem, so I already covered the light with electrical tape, but if I decide to spend another minute or two on the issue, I want to know where to look.
SOURCE: did brake job on 1992 chevy pickup, how do I release proportional valve?
some times you get an air bubble and you just cant get it to pass. you can work very hard and still not get it to bleed. snapon sells a bleeder system that sell for around $500 but i can tell you how to build one for under $20. if interested. but your answere is to back bleed the system from the farthest away wheel first. and then your peddel will come back.
SOURCE: The abs and emergency warning light comes on and
the red brake warning light will usually indicate low brake pressure,abs light can come on also,check fluid level,does brake pedal become soft and spongy?if so it can be the brakes master cylinder,if fluid level is low,can be a damaged brake line,inspect brake system,
SOURCE: Where can I find a brake proportioning valve for my 97 S-10?
When people tell me they hate there ABS, alot of people who pull trailer do. I tell them just to pull the fuse this will stop them completely. Yeah theres a light ont he dash but that can alos be delt with by removing the bulb for it. But int he long run just pulling the fuse is quick and Free.
SOURCE: How do you reset the proportioning valve on an
computer does that, or you have to have enough brake fluid preasure also, check for leaking lines (brake lines). make sure fluid is full.abs system has dump valves , if there was a problem abs light would be on. but abs might lite if not enough preasure hope this helps.
SOURCE: My service traction system warning light is on.
Most traction systems have sensors at each wheel. These detect wheel spin (can be a loose connection, broken wire, dirty sensor) The ABS won't work for the same reason but your brakes will work fine without ABS. (as long as brake fluid is full) The expansion bottle should have some coolant in it as well as the radiator. My experience is the bottle has a low level sensor that can get dirty ( If it was full) But you seem to be losing coolant? Is the lid on tight? Do you ever see coolant on the ground or in the engine bay? Sorry that's a mystery from here. Hopefully it is not disappearing in your engine. That would be a bad head gasket!
