rebuilt my front end and new front brake pads brake peddle did not pump up! replaced master cylinder but did not bench bleed. gravity bleed all 4 wheels 1/2 hr each and nothing so tried old school pump and bleed. peddle great until start it then cant get peddle at all !!! HELP

 

you can try bleeding at the master cylinder. bench bleeding does help alot if the master is full of air its hard to get pressure to push the air out. but pump the brake pedal a bunch of times, hold it down then have someone crack the lines at the master, repeat till you see no more air coming out then go back aorund and pump and bleed all 4 tires again starting with the back....its wierd like that some cars ill replace everything and itll be fine, other cars you spend hours bleeding

 

^ X2!

some get done in 10 minutes, other take the whole day!

do the bleeding in this order, RR, LR, RF, and then LF. you always start farthest from the master, working your way forward.

let us know how you make out.
