Post No Brakes???.....AHHHHH

Yesterday I took my truck out for the last ride of the year. I was sitting at a stop sign about 1000 feet from my house, waiting for an oncoming car to pass, when suddenly brake pedal to the floor…I mean and instant drop, floored it thru the intersection and just made it. I haven’t gone looking for the culprit yet, what do you think it could be. There isn’t any fluid on my drive way, and no obvious leaks that I could see. I’m fairly knowledgeable in braking systems; I’ve just never had this happen. I installed a new brake booster about the beginning of summer. Gimmie some ideas….

A peddle dropping to the floor is either a fluid leak or a bad cup seal in the master cylinder. The point that your peddle droped is probably when she failed. Remove your rear drums if you have rear brakes, you may not have lost enough fluid yet to see the leak without removing them. Check front calipers and hoses and all lines. Pull off vacuum line to booster to see if she's sucked fluid into the booster. If you've thoroughly checked out everything and no leaks anywhere you probably have a bad master cylinder, they can go bad but not leak externally.

I would blame your master cylinder. Take it a part and you will probably find a trashed rubber cup.

Hey guys went hunting for the problem today…and would you know it the pin coming out of the brake booster came apart from the booster. Like the pin that pushes into the master cylinder, like I said before, I just got a new booster at the beginning of summer, must have been a bad re-man. Napa is going to hear about this, big time…. <img src="graemlins/spank.gif" border="0" alt="[spank]" />

Sounds like a thrilling last ride, at least you have a memorable ride to go out on!
