I have no back brakes on my 71 dart.non brake booster car.I got one of those brake vacuum bleeder kits.still couldnt no fluid to come out of bleeder.tried havin someone pump the brake pedal still nothing.the brake pedal is very stiff i have a new brake master cylinder on and lines.what could it be?

did you bleed the master before install? is it a disc or drum brake car? there are different masters for them one has a larger piston and one is smaller on manual brakes the diference will affect pedal feel. i have also have blocked lines and distribution blocks before.

First thing is are you getting pressure out of both master cylinder ports? If you are then work your way from there back to the rear brakes to see where the stoppage is. If not be sure the rod from the pedal to the MC is adjusted right. Has this always been a manual brake car?

I had a shop put in while it was gettin painted,redid lines to.car was always a manual brake car.disc in front and drum in rear.

Seems if the shop put it in then they should make it work correctly.

Definitely right on that,they didn't.though they just needed to bleed.seems to be more than that now.

Like I said start at the master cylinder and work your way back.

sounds like the safety shuttle is tripped.

replace the rear center hose attached to the rear end

Before you replace anything I would crack fittings and see if you have flow. Either work from teh MC back or from the rear brakes forward, you will need a helper to work the pedal.

his first post eluded to cracking the fittings, unless i didnt read correctly.

My car has seemingly had this same issue. For my car, it was the rubber hose that fed the rear axle that had collapsed internally and needed replaced.

When I bought my 69 cuda I replaced the master cylinder, wheel cylinders (swapped the 7 1/4 rear for a 8 3/4). I bleed the front just fine, but could not get the back bleed. I tried the hand pumps, someone pumping the pedal etc. It ended up being the hose that connects to the rear.

I cracked the bleeders open and nothing from each one.brake pedal is so dam stiff u could hardly pump it.

If your talkin about the black rubber one,its been replaced.

New doesn't always mean that it's good.

As has been stated, start at the back and crack the lines loose and work your way forward to a point that you get fluid coming out.

It's either a blockage or a brake valve problem.

the bleeders are at the end of the line. You have the connection where the hose connects tot eh body hard line. crack it there and see if you get anything. If not, the hard line connects tot eh combination valve, crack the fitting there and see if you get anything. The combination valve is fed from the M/C, crack the fitting there and see if you get anything.

the problem will lay between the first leaking connection and the last one that didn't leak. If nothing comes out of the M/C that is your issue.

Get a helper and start bleeding brake lines.Start at the master and work from there.When you stop getting fluid flow,you found the problem.

As said; grab a helper to work the pedal & you starting at the MC.

If you don't have a helper I have found these and a little catch can to be perfect for doing it alone.
