I am going to change for winter tyres in a week or so, and i am going to pull all 4 rotors and clean the sensors thoroughly.
But i have discovered a trick to get the ABS working: when i start the car i press the brake pedal slightly at the exact same time as the e-brake light go out, and then i have working ABS! If i dont press the brake pedal the ABS light stays on.
Maybe i have some air left in the system? My ezibleeder cant take over 20 PSI pressure so maybe i have to get a brake bleeder that use more pressure to get the last air bubbles out? Or maybe i have to replace or make some adjustments on the rear proportioning valve?
Btw i have a 1989 model, and i have read here somewhere that pre 1990 models dont have a connection for scanning the brake system...
