So periodically the brake light would flicker on and off. I thought nothing of it because I just did all of the brakes. Well, the other day I was in the car in stop and go traffic. I was stopped with my foot on the brake when the brake light came on and before I knew it the car started going forward. I did my best to avoid the car in front of me and ended up hitting a parked car on my right side. Low impact but caused a fair amount of damage to the parked car and messed up my front end (marker light, headlight, bumper filler etc). I had the car towed to my mechanic. He thought it was a rotted brake line because he could see fluid on the line under the driver side but when he got the car on the lift he saw that the brake lines were in mint condition and not rusted at all. He thinks that some thing happened with the powermaster unit that caused the fluid to come out of the top of the reservoir. The brake fluid is pretty dirty also. Does anyone have any idea what could have happened. What I should replace? Where I can get parts???? I have also heard of the vacuum brake conversion. Is this a good idea? Any advice would be appreciated.
