So my car sat for the last 2+ months until i got the rad fixed, car is running great. I noticed right away my abs and brake light came on and if i hold the brake pedal it's constantly running the pump and if i pump the brakes the brake and abs light will come on. So if it's the accumulator where do i find one? Would it be possible because the car sat for so long that something is frozen? I really don't want to have to go parts hunting nor do i want to spend 300+ or even worst spend almost 700 for a complete new unit.
