Re: Installed adjustable prop. valve....same thing

Sounds like one I had today - front disc brakes, drums rear.
Not much pressure to the front - rear was fine.
Already had new hoses, new calipers, pads, everything,
he even blew the lines out.
He trailered it to me.
He'd been bleeding it till he was blue in the face.

Sometimes air gets trapped in the M/C. Bleeding at the wheels
doesn't get it out because it's not developing enough pressure
to force it out.
Try bench bleeding the M/C - even if you already did, try it
again.
You don't have to take it out - put a fitting in the M/C
outlet so you can put a hose on it, preferably a clear hose
so you can see the bubbles. Run the other end of the short
hose back into the resavoir. Pump it slowly, watch the fluid
get sucked back from the resavoir into the cylinder.
It "primes" the cylinder so it can produce enough pressure
to bleed the system properly.

Parts houses have "kits" for bench bleeding, makes it easy.

Thanks for the input guys! I'll give ALL of those things a try on Saturday, and I'll let you know how it turns out!

Re: Installed adjustable prop. valve....FIXED!!

It's FIXED!!

I went through everything you guys suggested, and I still had the rear locking up. I bought a MC from a waggie/cherokee/jtruck 74-78 models with manual brakes. This MC has a larger piston 1 1/8 compared to a stock CJ which is 1.

The obvious difference in the two is....the CJ has dual resovoirs with rear brakes getting their feed from the front (smaller) part of the MC and the front getting theirs from the rear (larger) portion of the MC. Now, the above mention waggie MC has two of the same size bowls and the lines are reversed. I believe the lines being reversed was the key here.

Either way...THANKS GUYS!!

Merry Christmas

Alec
PS. Now I have to tell my wife that I wasted $50 on an adjustable prop. valve that I didn't need....anyone need a slightly used prop valve? $45

If that's the way yours was hooked up, it's backwards. That was causing your problems. I bet you didn't need another master cylinder either.

Re: Installed adjustable prop. valve....FIXED!!

I always thought the smaller reservoir(front) fed the rear brakes and the larger one(rear) fed the front. is this wrong?

No, that is correct.
