my red brake light is now coming on.my dic says:ANTI-LOCK DISABLED, TRACTION CONTROL DISABLED then about 3-5 seconds later the dic will display:ANTI-LOCK OK, TRACTION CONTROL OK, SYSTEMS OK but the red brake light is still on.i have not lost any braking functions. i have tested the abs with the light on and it still works.i will have to check the pads today to see if they need replacing and are causing the red brake light.i will also try to run the diagnosis from allantesource.if anyone has any ideas i'm open.
It has nothing to do with pad wear. It is probably the vacuum pump or relay to it. Run the allantesource diagnostics to verify. And by the way, what year is your car. Its not listed in your signature?
i have eliminated the accumulator after running the diagnostics from allantesource.from what i am told it could now be the internal seals on the abs unit or low brake pads. my next step is to have the pads checked and replaced with a flush.
The only way I can think of that pad wear would cause the red light is low fluid in the master cylinder. I assume you've verified fluid level and that the float in the master is ok? Also have you confirmed the park brake pedal fully depresses the brake warning switch when released?
yes,i checked all that out.i also spoken with tom and we eliminated the accumulator.he says it can be the internal seals in the master cyclinder gone bad or low brake pads.i am leaning towards the latter because i thought i heard ever so slightly the feelers rubbing so as soon as i can get my car to clearwater i will have it looked at. if i need parts( other than pads) i will purchase from allantesource exclusively.( remember the light only comes on when i step on the brakes.if i don't use the brakes it will never come on.)
i could not take the pain of seeing the beast chained up so today i took her for a 15 minute tour!!!.it was all in city stop and go traffic.the only time i saw the red brake light lite up was when i cranked her up ( which it went out a couple of seconds later).during the whole trip which was about 10 miles the brake light didn't come on once.i am still going to have the pads changed and a good flush done and see what happens.
I repeat, the pads have no electrical connection to a red warning light. If the pads were thin, the fluid would be low in the master cylinder thereby turning on the red light. Thats the only connection between a red light and thin pads. If I recall, the level in the master is checked after depressing the pedal 20 to 25 times to depleat the accumulator. Also, thanks for the signature update.
