Quick brakes question

The line for the larger reservoir connects to the front, top port on the proportioning valve, correct?

WHAT you lost me a propreportionvalvrlydohicky!

J/K I hate brakes though.

Hopefully you are running the normal pro valve. Which has 4 holes one in front to go to front brakes. One in the rear to go to the rear brakes and two on top or bottom, I don't know how yours are mounted, both these goes to your MC the big one you speak of. I will fin a pick on line or take one tomorrow I have a cj with tub off atm.

Here is the stock style, has a great photo with labels on each fitting. They seem to be different sizes going to the MC so one is 1/2 and the other is 7/16 prob so we don't put it in the wrong hole.

The larger reservoir feeds the front (edit) brakes. In theory the fittings are different sized so you can't put them on backward.

Don't forget to bench bleed that master first or your next post will be about a really soft spongy brake pedal that no amount of bleeding will fix. The reservoir has to be level to do this, so it either has to be off the Jeep or you need to jack the rear up to level the reservoir. If it on a tilt, it will stay airlocked.

The larger reservoir actually should feed the front disc brakes.

You are correct, it is the front one that feeds the backs.

Disc brakes were an option in 1977. We don't know if this Jeep has them.

If the Jeep has disc brakes the metering valve has to be held open during the bleeding. The metering valve is on the opposite end from the rear brake outlet and has a dust cover on it.

SOME people say if you bleed the FRONT brakes first, then the rear brakes and THEN the front brakes AGAIN, you can get around this.
