On my 94 pickup we just replaced all the brake hardware and master and we got every put in. The only problem is we can't get all the air out of the lines, weve tried everything , hand vacum bleeder , hose from above the truck with funnle trying to push the air out of the lines we cant get it all out. we gotta get the truck outta my garage , help please!!!!!

 

Make sure that the rears are adjusted up appropriately. Out of adjustment rear brakes feel just like unbled brakes.

 

Are you bleeding the LPSV last? Did you bench bleed your master cylinder?

 

i just putt the truck in neutral and matted the brakes , the pedal gos all the way to the floor and just rolls!

 

Did you replace the calipers, and if so have you got them on the corrrect side of the truck. The bleed screws have to be at the top. And like dirtoyboy said the new master has to be bench bled first, it should have come with instructions on how to do this. And the lspv needs to be done after all the wheels.

Similar thread; may be of some help...

 

Confirm the LSPV (bleed it again). You will have about 10% braking power if everything is together properly and you do not bleed the LSPV last (or at all). I know this from experience.

Good luck! troubleshooting brakes is a bear.
