Hello,
I have a problem with brakes in this great GM 1990 ABS brakes systems ;) Sometimes (always after night) when i push brake pedal the brake light (red) is lighting for about 3-4 seconds. ABS pump is works. The same thing is coming when i push the brake pedal 3 or
4 times (pumping). Where is the problem?? Accumulator or Pressure Sensor?? Or both?? In Poland (I live here so sorry for my English) is very expensive to find the problem. Master Cylinder is early new from USA. Anybody have this problem??Greetings Kylo Buick Regal Coupe 3.1 V6
