    Brake Light blinking... Why?

    Well today I got my wheel bearing changed in the front. So I am driving my car back like after 20 seconds my brake light starts blinking. Anyone know why would that be on? Oh and I also feel the car shaking a little bit. I can only feel it when I am driving.

    if the abs light goes on also then its the abs module. if not, only the brake light than it could be the brake pads going? or a speed sensor? also, may want to check the brake fluid. idk im sure someone has the right answer for you. I know somewhere in the manual it says what it is, I was looking at it one time and saw something like that.

    Yea the ABS light is on. But the brake light was never blinking. Just started right after my front wheel bearing were changed.

    Check your brake fluids, if its low it could be your pads or its just low on fluid. If not then it could be the speed sensors. But most likely its the ABS module. does it also beep three times when the lights come on?

    If the sensor was damaged during the install or is not plugged in, it is possible to get the solid ABS light and the blinking BRAKE light. I'd take it back and ask them to fix it.

    unless they didnt plug in the sensors right or something is fucked up with them its 99% chance its the ABS module =D $2,000 fix from the stealership. There is a member on this board who rebuilds them for $50 and I heard hes good at what he does. Good luck, Im going through the same thing as you are, but my ABS module is fucked beyond repair, so Im just gonna have to pull the ABS and BRAKE light cuz its driving me nuts

    brake fluid. make sure it's level and full. If it is then possible ABS. Low brake fluid will flash the brake symbol and beep 3 times
