im having a hard time getting my rear brakes to work. I can jack the rear up. take the clutch out and the rear wheels will spin at idle even if i have the brakes pushed down as hard as i can. I though maybe the lspv was bad but i bypassed it with a piece of broke hose and still nothing. I have all new brakes and wheel cylenders. even adjusted the brakes all the way out and still nothing.

The weird thing is that when i open the rear bleeders the pedal dosn't go down. The front brakes work fine and when i open those bleeders the pedal goes down. what would make the front work and rear not.

 

I would start by running new lines from the rear brake cylinders to the MC.
My $.02

 

push on the brakes and open the bleeder on the lspv and see if you get anything
, if not check your line running front the master to that valve, maybe u got a kink thats not allowing fluid to pass through. if its good then your master has prob gone bad

 

well thats another weird thing. when i opened the bleeder on the lspv it would bleed out and let the pedal go down but now i have it bypassed strait to the rear brakes and i have a new ss line running down to the axle and 2 new solid lines running over to each new wheel cylender.

 

Let us know what you find out as I've been thinking lately that my rear brakes are gone as well.

 

it was the line running to the back. it would blead from the lspv but after i found out that i could stop it by pressing hard on the line i figured it was that. rear works great now. although the front started leaking out the caliper now. if its not one thing its another.
