There is a leak in the abs accumulator that causes my breaks to pulse and a alarm to sound, which is a loud whining noise. I have had my rotors and break pads replaces but that did not resolve the issue, my mechanic thinks is it the accumulator, which cost 1800 dollars just for the part. I have researched and seen hundreds of complaints about this part online. I can't afford to pay 2k for a repair at this time and I am afraid to drive my car but I have no choice due to my work and need to commute.
