HELP BRake Problems!!!!!!

[eryk]

ok so i replaced my ball joints and then i got back in the truck to test drive it and my pedal went to the floor brakes still worked but i had to slam it to the floor and it took a good 3 seconds to stop. I replaced a possible seized caliper, the master cylinder (i bench bled it first to get all the air out), i checked all the lines to see if there was a whole or some sort of leak but nothing. So then i adjusted my rear brakes and still the same thing. The abs and brake light is not on either. Does anyone have any idea on what this could be? im really at a loss

Can you pump them up until the pedal is firm?

If you can, then you either have air in your lines yet or your rear brakes are still in need of adjustment.
Since you have ABS, it is really difficult to get air out of the ABS unit. I recommend cracking your bleeders at all four corners and letting fluid drain for a few minutes while keeping the resevior full. Then bleed the brakes starting with the left rear and working your way forward.
Your rear shoes should just touch the drums, then be backed off a quarter turn.

i just tried it and nothing the pedal still goes to the floor, could it be the brake booster itself?

No...you have have a defective master cylinder. It's bleeding off internally
