I have a 70 challenger. Cant get the driver side front brake to bleed properly. Stock drum brake set up. 5 year old m/cylinder and new wheel cylinders. Checked and cleaned bleeder valve. still only minimal fluid flows out and on test drive its obvious the bake still has air in it. Ive rebled the whole system again...same problem. No leaks at wheel cylinder or lines. Any help would be great...thanks

I would suggest checking the rubber line going from the frame to the wheel cylinder. I had one collapse on the inside and it would not let fluid pass. If the line is old that would be the first thing to change.

Welcome aboard. You are getting a good stream out of the pass side but way less on the dr side? If so take off the hard line at the hard line/hose junction on the pass side & recheck. If the hose is unobstructed. Otherwise bleed the M/C first then repeat on the corners RR LR RF LF. I like to put a block of wood under the pedal so it does not go past its' normal travel & easier for the helper to move the pedal down & hold it till you close the bleeder on each stroke. Holler how it goes.

Thanks for youre response, but I should have mentioned I disconected the rubber hose at the cylinder and the fluid seemed to flow out fine. I replaced all the wheel cylinders because I thought it would resolve the problem......

The problem is the air (they will pump up briefly) but wont bleed out? When bleeding you got good flow on all 4 corners (out the bleeders) except the 1 front side? Good flow at the end of the 1 neoprene hose with it unhooked from the wheel cyl? Either the wheel cyl is plugged (highly unlikely) or the bleeder screw is partly obstructed (possible but it is new). I feel like I am missing something. Since the wheel cyls were replaced here I'd think I'd (just me) rebleed the MC then rebleed the 4 corners. Even a dribble can get the air out (as in gravity bleeding).

I think you may be right about bleeding the m/c. The car sat for about 6 months before this. I drove it and noticed the problem. When I checked the m/c, the rear section was completely empty. Dont know where the fluid went. No signs of leaks, so I figured I would replace all the wheel cylinders since they where fairly old and bleed it out. But I think youre right the m/c should be bled. Probably has air and sending it to the closest wheel...

Is that a power brake car? Maybe the master leaked into booster?
