Lost brake fluid

Post by B.O.B. »

So brakes got a little spongee and looked at fluid on the big compartment is almost dry. I take it that the big one is for the front. Looked around and nothing is leaking. Any thoughts?

Fill it up, bleed and then see if you can find some-way of putting pressure on the pedal while you look. A scissor jack off the seat can work. Got to have a leak somewhere.

Could also be a slow leak from the rear drum cylinders.

Don't let the smoke out of your wiring. It's really hard to put back in.

My Master Cylinder leaks from the cap. When it does it drips onto the header/exaust and burns off instantly. Just a thought.

Yeah, I've had the same not that you mention it. The wire clip on top was a little loose, so I took a hammer and hit the wire between the two bowls to take the slack out and that stopped the leaking.

I fixed mine by putting a piece of rubber hose around the wire.
