I have an intermittent red brake warning light on my dash. Seems to occur most regularly when the outdoor temp. is cold. Light goes out after car is driven for awhile. No other problems noticed. Brake lights work okay. Brakes function good. Maybe a sensor problem?
Check Ebrake is down all the way or
brake fluid is low in master cyl
worst can be bad ground in the wiring harness
causing light to flicker
My 2000 accord brake indicator light comes on when cold. Fluid level seems good. The light will go out when car warms up. When I took the cover off the reservoir I noticed that the rubber gasket ring was stretched out and flat in one area. When the cover was installed with the gasket like this I'm not sure if it sealed completely. I went and found an o-ring that fit in the groove around the top of the cap better. Reinstalled cap and light does not come on. Will monitor to see if this fixed the problem. The original o-ring had a flat tapered design and I replaced it with one that had a round design. UPDATE: The next morning it was cool and the light had come back on. I unplugged the wires and removed the cap. I hooked up an ohmmeter to the two leads and moved the float up and down on the cover. The resistance value changed when the float got almost all the way to the top. (The value went to infinity) When I reinstalled the cap I put the meter on the two wires and it indicated that the reservoir was not full. I added a little bit of fluid and checked the resistance again. It indicated that the level was full. I hooked up the wires and the light went out on the dash. Will see what happens and will update either way. UPDATE 10/1/2015: Light has still not come back on. I guess the fluid level needs to be all the way to the top if the float sensor is really that sensitive.
Your emergency brake is a mechanical brake system that is indipendant of the regular hydrolic system. If the red brake light on the dash is on make sure it's the emerg. brake and not a problem with the fluid level or the calapers sticking. the best way to check the emerg. brake is to rase both rear wheels off the ground and spin them. If they spin, the emerg. brake is not locked up. If they don't spin, take the rear tires off and the brake drums. (you may have rear disk brakes.) check the springs to insure they are all hooked up properly. If there is no problem there, follow the parking brake cable to check for damage. The cable is like a brake cable on a bike, If the inner cable is binding inside the cable sleeve,the brake wont release. If you have rear disc, it's probly a bad calaper.The park brake cable is attached to the calapers. Rember if it wont run it's annoying but if it won't stop, it's deadly. DON"T experiment with brakes!!! If in doubt, take it to a pro.
