The ABS pump runs every time I step on the brake, so I assume the accumulator needs to be changed. The manual I have for the car basically says take it to the dealer for ABS problems, but I would rather not pay that kind of price. I know where to get a rebuilt accumulator, but I need to know what else has to be done. I would guess that you relieve the pressure by stepping on the brake a bunch of times, but then what? Do I just unscrew it? Will it come out without removing the entire master cylinder? Do I need to bleed afterwards? What else am I missing?
