I replaced the front brake pads and the next day the power brakes failed, I was only getting pressure to the front brakes and was unable to find troubleshooting info on this machine, I took a gamble and replaced this part and it fixed the thing. Now I have power brakes front and rear.
Parts of it worked but not out of the Box. Accumulator Ball was no good causing Red Failuare lights
to come on in dash . Replaced with orignail Ball off old unit. Working Fine now.
