Brake help

91 Festy brake fluid leaking and looks to be under reservoir. Filled up twice in week when brake lite on dash came on.

Thoughts?

Thanks

Master cylinder leaking out of the back. Bet the fuel filter has lost it paint.

Advanced Auto list two, one for $40, plus $15 core charge, which was supposed NOT come with a resevoir and an $85 one, which was supposed to have a resevoir.
Got the cheap one, because I have swapped resevoirs before, and have a better plan than last time to swap one over.
Picked up the part and it has a resevoir, plus sensor, plus bleed tubing and fittings!
Score!!!!!!!!!!!!!!!!!!!!!!!

Thanks! You are right, the fuel filter is about paintless. Is there much trouble to change the master cylinder out?

As long as you're two brake line fittings aren't frozen to the master you should be fine. You will have to bench bleed the new master cylinder and you will probably have to bleed all four wheels. Once you take the two lines off the master air will begin to work its way into the lines. Other than that there's only two nuts to undo, which you might want to replace with some stainless lock nuts just to make things easy in the future.

not quite, John and I swapped a MC into his festy a couple years back IN CAR. the trick is to gravity bleed the master with the line holes at a slightly upward angle before installation. as for the old unit, crack loose the brake lines (DO NOT REMOVE), then remove the master from the booster and rotate the whole unit so that the hard lines are at an upward angle before removing them from the master, this will keep any fluid from comming out and being replaced by air. then place the NEW unit on the hard lines before rotating the assembly back onto the booster. then with one of the hard lines locked down, have someone press on the brake pedal and bleed the other line, then swap lines when you stop seeing air. Do the same procedure to the other line and you're done.
