FJ40 brakes.

It goes in from bottom then comes out the top

Update. Figured out I have a leaky wheel cylinder. Brand new from Lordco and it's leaking no exchange... not sure if that's my problem for no brakes but good start I guess? Anyone got a new left rear left cylinder? Lordco is out of stock on them.

Still zero luck with my brakes. I was looking online and people were saying pull out the residual valve since it has front disc conversion. Residual Valve Removal - Land Cruiser Tech from IH8MUD.com May give this a try

Update: for anyone that cares. I have figured out this braking mystery. After going through like 2 different sets of wheel cylinders and 3 masters. They kept blowing out. What I did. Bench bleed the master, set up rear adjustments and I still had to pump the brakes up 3 times for a pedal. Then what I did after which I could not find anything on it about is crack that bolt that's on the side of the master with a buddy holding down the pedal while I did it and then now I have brakes. I bled the brakes front and rear separately for 15 mins each with our pressure bleeder at work with no success. It's just that stupid little valving system that's on the master was the problem.

What are the odds that three masters have the same problem with the residual valve?

I thought the bolt on the side was a stop for the piston?

Who knows :/ Just as soon as I bled that I suddenly had brakes nothing at all before

That reminds me.... I need to bleed my brakes..

It sounds like those brakes have been a major pain in the rear (understatement and a half)... I rebuilt my drum brakes once, swapped the front to discs, and then swapped the rear axle, and then later the rears to discs. Having gone to 4 wheel discs, I'd not do it any other way. Soooo much simpler, almost no maintenance, and 10 times the braking power now that I've got an 80 master and booster.

If they are working, run them till they don't... but if they need to be redone again, I'd ditch them.
