Hello, I have a problem with ABS and brakes in my Buick Regal 2dr Ltd. When I started engine, sometimes everything is ok. But sometimes after about 1 minute, antilock light is flashing and sometimes after a couple of minuts is still lighting. When i stop the engine and start it again everything is ok. When antilock light is flashing ABS works when still lighting not. I see that ANTILOCK light flashing after a longer break If I drive for some minutes and restart the car this light stopflashing... and won´t begin flashing more during that trip even if I do more breaks. And sometimes, after big traffic drive BRAKES light is still lighting but brakes works good. I hear that the pump is still working when the BRAKES light is lighting.
Any suggestions where is the problem? I live in Poland and haven`t any dealer. BTW. Does anyone have the owners manual for 1990 Buick Regal in PDF format?
Thank for all advices Christopher "krzysiek (at) dl (dot) pl"
