I have a '91 Briarwood 4WD with antilock brakes; the rear brake line rotted through and I'm looking to replace it. I've removed the hard line up to the flex line junction. The problem lies with the flex line from the hard line to the distributor block.....the flex line's fitting is so badly corroded I'd rather just replace the line, but I don't see a hex fitting at the distributor block. Does this mean the flex line and block are replaced as an assembly? Or am I missing something........?

 

I think that its so corroded that the hex is gone, I would take off the junction block and hose and match it up at the auto parts store. Good luck

 

This is the hose you need. It does come apart from the "T" as you can see. Clicky

 

Take a look the part that Blue linked. You will see that the flex line and junction are one piece. The block is held to the axle with vent bolt on the top of it.
