If your abs pump seems to be running after every few steps on the brake pedal or if your car has a hard brake pedal, more than likely your accumulator ball has failed.
There's a rubber bladder inside the ball that deteriorates over time more than from actual use.
If you still hear your abs pump running but still have a hard brake pedal or abs light comes on, most likely the accumulator ball is the culprit.
This is a brand new ball, not rebuilt

It's a little larger than the stock accumulator in a 1988 Thunderbird but it will fit and does work.
awesome from the delivery to the installation !! would definitely purchase parts again !!
I've looked for one of the for 5 months to repair the brakes on my 1990 McLaren ASC Turbo Grand Prix. It fit and work fine on it. I can drive the car again!!!!
