Distribution Block P/N?

[Raven]

The block was frozen. At first I couldn't even open it but afterwards I was unable to push out the plunger or what ever its called. Anyway I cleaning it up and it seemed to work ok. Bled the front disc brakes fine and the rear drum brakes without an issue. Drove around like that with no issues until the other day. btw the master cylinder is brand new and was bench bled properly. I figured the brakes maybe needed to be bled again. This time there was zero brake fluid going to the front discs on either side. The rear brakes seemed to be fine but the fronts were dead. 

 

I think the distribution block needs to be replaced. I'm having problems finding now for an MJ. Only one so far is from Napa and they want 100 USD for it. Does anyone know where I can find a new one for a decent price?

I would have said that it's impossible for the distribution block to not allow brake fluid to get to the front wheels. The passage goes straight through.

Limey... thanks 🙃

 

I'm going to look it up... I did go ahead and drop one of my old ones, just the bare block, into the ultrasonic cleaner. Then took that piston rod, or what ever it’s called, out of a clean late model XJ and installed it into the block. I’m going to set this aside for now.

Have you checked for pressure at the master cylinder outlet?

I have a good working block laying on the shelf if you need one

Cruiser54... it’s a new master cylinder. I properly bench bled it. I know new ones can go bad but I will know as soon as I have time to work on the MJ. 
 

ghet... thanks I will keep that mind. For now I have a second used block.
