Brake pedal went to floor, now works fine???

[FWP]

Only did it once, on top of some 4' rocks Thought I broke a brake line, got out and looked, found nothing wrong. Got back in, started it up, and the brakes worked fine the rest of the trail, and they still work now.

What do you guys think? Anybody have this happen? Maybe a piece of something got hung up in the seal of the master cylinder

Booster could be going out.

Booster could be going out.

I've always heard that a failing booster would manifest itself as a HARD pedal, as it wasn't offering any, well, boost, as opposed to a soft one.

Seems more like a leaky master or, as FWP said, crap in the master, which can't be good.

Maybe an air bubble snuck in a bleeder screw or a fitting -- or maybe the master burped a little air 'cuz you were at a crazy angle?

Mine went out , TWICE

When mine went bad , it went to the floor first , then it was kinda hard after it was down there .

You get so good at getting the pedal unattached when ya do it often . I must have an imprint of my drivers seat and my carpet on my back

Snort. Just don't leave bits of broken fuses on the floor, as they embed themselves in your elbow

Hey, do you have any idea *why* yours failed? I had a leaky master and I'm wondering if brake fluid made its way INTO the booster, and if that's bad.

My first one was unknown vintage , came on the truck . Second one was an Autozone job that went .

So far 3 years on the current one , same M/Cyl . So doubt it was a leak in my case . I haven't even done my back brakes in forever and she stops fine everyday since .
