Check the fluid level in the brake fluid reservoir (master cylinder). A slightly low level will set the light off as the fluid is being rushed backward during acceleration. When this fluid is rushed back, the level of fluid is probably dipping below the desired level therefore setting the light off.

I recently hit a deer on the front right side lost that lamp now my dash lights and tail lights are out other head light comes on and brake lights come on when i push the brake pedal i ve checked all...

you have blown the side light fuse when the headlight smashed ,somewhere the wires are bamaged or the side light bulb has broke and the filament feed wires have touched causing the fuse to blow ,also look under the bonnet next to battery their is a power distribution box next to batter ,check uses in here as well ,they are not markewt though so look for a red 10 amp or a blue 15 amp fuse

Electrical issue with 1992 pontiac sunbird. lately when i put my blinker on it is really, really slow (unless i am accelerating) my speedometer needle moves up and down slightly, then the anit-lock brake...

How much amperage is the alternator putting out? To check this, put a volt meter across the battery terminals. Boost car & let run. Remove booster cables & read the meter. It should read over 13.2 & if battery is weak or uncharged it should be as high as 14.5. You could have part of your diode trio burnt causing the alternator to only charge when reving high & current in low demand i.e. when lights radio, & other electrical equipment off. I think this is the problem. Good luck! Also you may have the trunk mercury switch malfunctioning & leaving the light on in the trunk thus draining the battery. Temporarily remove bulb & see if problem persists.

Brake light comes while braking with no apparent cause

The pulsating sounds like rotors warped from overheating. As far as light goes, may be float or sensor at master cylinder faulty & making light trip.

Brake light, battery light, antilock brake light coming on

this issue sounds like a grounding issue, teh main clue being everything gets dimmer. sometimes an additional ground is a faster repair than finding and resolving under dash issues.

This issue will likely NOT be battery or alternator.

Love the right rear tire clue, and it should not be related..

You have a serious vacuum leak affecting the engine and a brake proble, -The connection between them is the brake vacuum assist and the brake master cylinder. The brake master cylinder is the target componant. Change it out and other related problems should be resolved. Good Luck &be safe-Ned
