brake probs, big-O says! - Pirate4x4.Com : 4x4 and Off-Road Forum

okay so i just installed crown performance ext ss lines in front and back. the front ones made me a bit weary, they didnt have the little notch to line up the line with the bolt that has the little holes in it, no what im sayin??

so any who i bleed the brakes with some friends and i was pretty confident on how i did it (first time) made sure there were no bubbles, all that good stuff. any ways after i mounted the tires, the brakes pretty much went all the way to the floor, like they still had air or somthing, toook it to big-0 cuz i was plannin on getting my new tires mounted, stepped up to 33"x12.50", (also just installed tc uca's and ivd ext coils) so i asked them to bleed the brakes and swap out tires, went back and they told me tires wont fit and brakes dont work!!!
well i new the tires wouldnt fit all the way, i need spacers, adjust coils and trim fenders, they mounted them anyways, but they told me the master cylinder is leakin from the bottom! i dont know how, my truck sat for 2 months after i busted the suspension and had to save for new, but the brakes worked like champs before that. So i kept an eye on it and i havent seen shit leaking out!! but the brakes are still very soft, not safe to drive!

so my questions:
-could the new brake lines have something to do with this?
-the reservoir is mounted to that grey piece but i can see a small amount of fluid in the O ring in there??? maybe leak?
no fluid has drained from reservoir!?
-I noticed there wasnt any sign of drainage at the BPV in the rear and yet there were signs of drainage at all other bleeder valves, maybe they just didnt bleed that one and it could cause it to be soft, cus the brakes are better then they were when i did it. not by much though.

well i hope someone can give me a clue on what to do with this, i finally got my truck almost ready to drive after 2 months!

aslo its an 2002 taco, no abs, 4x4 trd

oh and the guys there broke my shell rear door shocks THEY WERE BRAND NEW! they told me they would replace it though.... and they didnt charge me for the brake bleed!

Likely air stuck at the lspv, bleed it.

If the paint is missing on the booster, under the master cylinder, then the master is shot too.

any way to bleed the abs contoller? its a high point in the system and could hold some air?

Try it in this order:

Rear passenger
rear driver
porpotinoal valve in rear
passenger front
driver front

just remember to check fluid after each bleed.. Try it in that order a few times and if it's the same you need to try to bleed master cylinder then repeat..
