help with brakes?
hey all new poster here hope someone can help me out. i have a 99 2500 4x4 5.9 gas . finished puting the front axle back together after hanging seals. took it for a test drive and lost brakesafter about 10mi pedal just went to the floor! cant find any fluid leeks and fluid level looks good. with the truck off i can push the pedal and get brakes (pedal gets hard can here the calipers moving) as soon as i start the truck goes right back to the floor. first thought was the booster or master but wheen i look on the web i see al sorts of pepole having problomes with abs controler and dont have a lot of money right now to throw parts at the probloem. THANKS

if you have a firm brake pedal when truck is not running,
and then completely lose the pedal when the truck is cranked, i'd suspect the booster.
this is a question- is there any way to prove it by disconnecting and bypassing the booster vac line ? you'd not have power assist brakes, so be careful.
