Late Series 2A brake problem

Hi does anyone have any ideas?
Got a later Series 2A SWB (single circuit). The rear nearside bakes keep seizing on, almost like the fluid is not returning back.
Changed both the master cylinder and wheel cylinder twice, changed the rear flex and renewed the copper rake line from the T piece to the nearside rear.
Getting frustrated now!
Any thoughts appreciated.

If its only that one wheel then you must have a mechanical issue.

Collapsing flexi pipe?

That was my initial thought - but OP says he changed the flexi.
T piece could be blocked on that side - I guess.

Doh….forgot it’s the rears… only 1flexi.

Have you used the old shoes?
You put the springs back on the correct way?

have you got a bit of play in the master cylinder rod to allow fluid to return?
(But weird as it would/should affect other brakes)

That wheel is furthest from master cylinder...when you say seizing on is that under braking? and how does it release itself...have you checked other side to see if both are adjusted correctly...jack up rear jam pedal down and check adjustment...also take hub off and see if shoes are adjusted correctly to the back plates if they are squint they will grab...
