All of a sudden down to the floor No leaks anywhere master wheel cylinders hoses fittings Any ideas would be helpful
I believe that's "brakes".......master cylinder piston/cup failure would be the most likely explanation, so long as the push rod hasn't fallen out of the cup.
That is what I thought it's a bitch to get at under the driver side floor no acess panel guess I'll yank it out and take it apart
Grammar police are here! Good job fixing the grammatical error boys, but how about helping FANG out. Even after the first "brakes" jab there was no rebuttal so give it a rest. FANG, I agree with Ricks Garage. Just get another one and save yourself some heartache.
On the Jeep wagon or ??? Check the master cylinder to see if it has enough fluid in it and go from there. The push rod could have come out of the piston or come off the lever but that probably isn't the case. Single or double master cylinder? Singles usually just leak fluid out the back when they fail but a double cylinder will bypass internally. You can usually figure out the bypassing if you can pump the pedal up and hold it and with a slight pressure on it it will gradually drop to the floor. I don't rebuild double master cylinders as I have never had good luck rebuilding them. If it is a single master cylinder on the other hand and you can hone it out good it will probably hold ok for a few thousand more miles. But in a lot of cases a new master cylinder doesn't cost all that much more than a rebuild kit. I'd look at the wheels again because my bet is that one of the wheel cylinders is leaking and you haven't spotted the fluid on the back side of the tire yet.
Yea. I had a galaxie a few years back that had brakes when I left the house and no brakes when I arrived 12 miles down the road. New master cylinder cured it.
