    ANY HELP WOULD BE APPRECIATED! my 03 limited V8 4 runner
    is down right now due to what appears to be an ABS braking problem.

    a lexus mechanic used a scan tool the codes come back to the Brake actuator and accumulator pump ( cant drive as the brake pedal is rock hard )

    has anyone fixed this problem ??

    what was the cause?

    I'm told a new complete unit with Master cylinder and acc/pump is around 2700.00

    a new accum. pump alone is 1600.

    and a used from ebay between 500-700

    Hello, I am having this exact issue, where you able to resolve the problem? I believe its the brake booster portion that is faulty. I will attempt to locate one at the junkyard today, like you said every piece in the ABS/Brake booster assembly is very expensive.

    I know there is a special tool needed to bleed this system once anything is replaced and the lines are exposed to air.
