LC BJ74 rear breke issues/also is pulling to the left when braking

[Marv5]

Well long story short, the LC started to pull to the left when i press the brakes, so i decided to upgrade the caliper with the 4runner 3rd gen. I got the all done, wet for a test drive and still pulling, so i check the rear and found out they weren't working the had no pressure, well i put new cylinder wheel and shoes
then i tried to bleed the system and no hydraulic fluid is coming out of the rear brakes.
After that i check the LSPV bleeder and is got pretty good pressure i also rose the lever all the way up, but still not work .
Any ideas what should i do next, or have you run into this issue, any advise will be appreciate

I guess you are not leaking fluid.. You don't mention it.
I don't recall if the LSPV lever up or down increases or decreases rear pressure.
I would disconnect the hoses and lines starting at left rear wheel cylinder.
Work towards LSPV.
Look for fluid.

No leaks,

thanks for the info.

When I wanted to test my LSPV I disconnected the far end of the arm then strapped it fully down. I tested the brakes that way and then wired the arm fully up. There was a difference and I ended by extending its mounting bolt higher.

In theory a brake line could rust or swell to the point of blocking the fluid.

The LSPV would be "more level" without a lift, so when lifted, it flexes down and ideally should be spaced up for it to work properly.

Yeah, maybe a blocked/rusty brake line, or while bleeding it, some junk went down into a line and created a blockage.

Pull the main rear brake line and check for pressure there, then out at each wheel cylinder.

Hopefully , thats the case, i'll check on that as well.

Thanks
