I have a 73 Duster, front disk rear drum, that I bought with a line lock installed on the front discs just under the Master Cylinder.
When I first got the car, the line lock was disconnected, so of course I remedied that immeditatly. Now, if I press the brakes (hard), and engage the line lock, it will hold untill I start revving the engine, then it wants to creep forward. A couple of times I found that if I pumped the brake peddle, it would hold better.
Pumping is usually an indication of air in the lines, so I bled the front brakes, and still have the same issue. I can think of 3 root causes:
1. Air still in front lines
2. Line lock is not holding the locks, it is leaking slowly.
3. Air in the rear lines. I don't know if thios would cause the problem, but then again I'm not sure.
When I press the brakes hard, the rears will lock before the fronts, so that seems to negate root cause #3 above.
Thoughts?
