If you try bleeding the master, you MAY see that very little fluid is coming out around the fittings. But, it's harder to tell than when you're using a regular bleeder.

What did the original fluid look like?

Real nasty?

The original fluid wasn't that bad. Haven't tried to bleed the mc yet. Does anyone know if it has anti lock brakes?

Only you. We need a pic of the Master to tell from here.

It has a level sensor on the rear axle that restricts flow when there isn't a load. I popped mine off (the rod that is) and lifted it up to bleed. When that wasn't enough (I had a broken line in the back that I replaced) I loosened the return line under the pressure differential valve (under the brake booster/master) and got LOTS of air from there. When I went to 33" tires (33/9.50/15) i removed the return line (plugged it with a cap on the PD valve by the master cylinder and bypassed the load level valve in the rear) The drawback to this is the level sensor is an anti-skid device so you have to be careful in the rain. With better front brakes (off a ZJ) and an upgraded master/booster ('96 XJ) I can stop at 55 mph while pulling a 3500 lb load while having a motor/trans in the back of the truck for "ballast".

Comanches didn't get factory ABS. Just the rear anti-skid valve.

Just put a new master cylinder on it and still nothing. Almost like its worse then before. Bled everything. Still air in the lines. Checked all my connections and lines. No leaks.
