Brake master cylinder/booster?!!

Ok maybe I am a little slow, but hear me out. It should be fairly obvious if my 79 cj7 had a power booster for the brakes, correct? It should be right in front of me when I open the hood. So my question is, do some 79 cj7's come WITHOUT the booster and only a master cylinder? If so, what is involved with changing the master cylinder out with a new one? Mine is leaking.

Yes, they had manual and power brakes.

Very simple:

Break the brake line fittings loose and then snug them so they don't leak.

Un-clip the actuating rod from the brake lever inside the jeep.

Unbolt the master cylinder from the firewall.

Unbolt the brake lines and pull it off, have a catch pan handy because it will lose the fluid when you take the lines off.

And welcome to the forum

Ok, so upon further investigation. The lid for the master cylinder is leaking. It is brand new and was put on when I bought it a couple of months ago. Does anyone know of a nice no-expensive to fix a leaky lid?

New gasket or another new lid with a new gasket. Both are cheap.

This is how NAXJA Midwest Chapter elected officials like to treat their resident users and former multi-year supporters.

I dont know how people live with a jeep with a brake booster. I would be dead by now because of how many times I have been on a hill and my jeep has died and I had to slowly roll back down with only brakes and some gears. With a brake booster installed, I would of had hardly any brakes....


Simply put, I love standard brakes.

Boosted brakes still work fine with the engine off. They just feel like manual brakes.
