Brake fluid canister

I have break fluid leaking out of the top of the canister. The gasket in the lid looks ok also is it normal for the lid to be able to slide around a little bit? The clamp is a little bent so it might not be as tight as it should. Brakes work fine, and its not a real bad leak. Any ideas cause im out lol.

Re: Brake fluid canister

Might not hurt to throw a new gasket on there.
I had a brand new master cylinder that had a leaky gasket. It looked fine, but apparently wasn't.

Re: Brake fluid canister

Yeah I figured it would be the gasket. I don't think im gonna replace the whole thing but like you say it probably will be a pita to find one. Thanks guys for the quick answers. Oh and do you know if they sell a whole new lid with a gasket?

Re: Brake fluid canister

My circa 1977 master cylinder never leaked. My brand new 2 weeks of use one does and ruined the paint on several things. Really hate repops.

As far as I know its not a repop. Autozone and orielly both show to have the gasket in store, so I guess I need to start making a parts list....

Re: Brake fluid canister

Pop the retaining wire off, bend it a bit and put it back on. It should be hard to slide into place.
Do you have the rubber anti-slosh gasket inside the cap or are you trying to seal metal to metal.

Re: Brake fluid canister

Re: Brake fluid canister

Bought the gasket. Wouldn't fit. Before I bought the truck it had been sitting for about a year so should I go ahead and just replace the MC?

Re: Brake fluid canister

You said it doesn't leak much and moves around easily!
Go buy a new cap. Comes complete with insert and new wire.
Here's a sample. Maybe not exactly like yours. But....

Re: Brake fluid canister

Found the exact same gasket at the scrap yard; it was in good shape so I bought that cap and wire doubled up on the gasket and it barely leaks. I will admit I accidentally put a little to much fluid in.

Did you just put the other gasket under your current gasket? Wondering because I still have my old MC cover with the gasket I could use.

Re: Brake fluid canister

The gaskets are bendix 222TI68. they just slip into the groove. I notuced pretty much all the MCs there would work with my repacement gasket. My MC is about a 1/4 in. longer and rounded at the top the the dorman one I posted earlier.
