so after i did my sas swap and lc rotor mod and did the suspension in the rear i go to try and bleed my brakes and seems like its not getting enough pressure. I've bled everything front and rear and the lspv and yet seems like the only part of the system that is working is the rear brakes. If i keep pumping about 10 or so pumps and hold it feels like i have a brake peddle. Once i release and let it sit for about 45 seconds its like there's nothing there. I've bled it completely through nice clean fluid coming out of every bleeder. The master cylinder was working perfectly fine before. Would the back brakes work if the master is toasted? any suggestions or tech would be much appreciated.

make sure the brakes are adjusted
the lspv bracket on the diff needs to be raised.

I unbolted it and raised it all the way up and zip tied it up for maximum brakes with no difference

haha thats what i did on my 85 4 runner.

did you put in an extended brake hose? I always had spongy brakes when i had extended rubber hoses after lifting my truck. that went away when i put steel braided hoses in.

is the back brakes stock? or swapped to calipers?

Ss brake lines for extentions up front and stock drums in the rear
