Powermaster problems...ran accumulator test from gnttype.org, it falls within specs, warning light turns off 5 seconds after system is depressurised, but my problem is that when i push the brake pedal, the brake light comes on for a split second, brake motor runs during that time, then shuts off as well as light. The car does not brake well during that split second. If I push the pedal really slow and light, brakes operate normally. However, under normal to heavy operation, i have the split second delay as well as light on for that split second. Could this be the accumulator even though it supposedly falls within specs?
