So today my brother called me and sadi that his break caliper locked up.. He ended up replacing both calipers and new pads, After bleeding them like the usual process, he said that he then backed out of the barn and the pedal went all of the way to the floor. Even after a few pumps they start to work a little bit but still have to go all of the way to the floor. please help, he needs the truck asap. thanks

 

I would venture to say he still has air in the lines. Have someone pump the breaks while he bleeds 'em....

 

I would think that also but with the truck even not running the pedal still goes to the floor. He did think that but he had already re-bled them a second time.. thanks for the help man

 

Is he leaking fluid from the pistons on the caliper or the lines? Does he have reservoir full of fluid? I'm sure he has confirmed these things already but you never know.

 

yep he has confirmed all of theese. i am thinking maybe the master cylinder bad or the brake booster. hoping not but jsut looking for some other words of encouragement.. haha.

 

Well maybe someone will chime in who can shed some light on it.
