what a ride

[rebel33382]

Just got off of work this AM, went to back out the parking spot, brake pedal went right to the floor, wooa! Got the flashlight out, checked the master cylinder level, fine, checked for leaks around the inside of the tires, nothing. Played with the brake booster vacuum line, no problem (since I just sea foamed thru there 2 days ago) What the heck guys???? I had to pump the pedal to get it to stop. While I was moving along and I hit the pedal went right to the floor, had to pump it to get a "pedal" and to stop.

It sounds like one of two things.

1. you have an internal leak in the master cylinder, and it needs to be rebuilt, or replaced.

2. there is some kind of metering valve for the rear ABS system, I know that there is a link to a discription to how it works around here somewhere.

This isn't the thread I was thinking of, but it is the first I found.

Thanks
