86 buick brake problem

Having a brake problem on my 86 buick lesabre. My right rear brake seems to be getting very little fluid, to actually engage the brake.
I've replaced the master cylinder, brake cylinder, still no brake on that side only. I did bench bleed the m/c prior, have checked for leaks.
My only thought I think they are called individual proportioning valves that screw into the m/c for the back brakes. Possible one for that side went bad? Kind of at a lost what to check next. All the other brakes seemed to have bleed fine and working ok. Just the right side not working.

i have had this happen on a chevy truck on the front right... the rubber line had collapsed to that caliper and wouldnt let any fluid through.... it looked just fine and wasnt leaking but the line on the inside had collapsed not allowing any fluid through at all... so check your lines maybe a wrecker driver hooked it wrong and crushed the steal line it would half to be somewhere after where it tees to the left rear side not the master cylinder.... just check it out...

it is also the firthest from the master cylinder so it could still heve air in the lines from when you replaced the master cylinder... i would check the lines and make sure their not crushed or bad then bleed it some more... it could also have a peice of trash in the bleeder not allowing very much fluid out... so you migh check the bleeder... just something to think about ... hope this helps

Just so you know, that's probably a crossed system, not front/rear but RF&LR/LF&RR,

The m/c is a 4 port individual lines to each brake. I'll check the brake hose to that brake, thought did cross my mind it could have collapsed. Thanks

Normally when a hose collapses, it does so when the Brake pedal is released and doesn't let the pads/shoes return locking the Brake.
