My 28 ford PU suffers from a brake problem that has been there day one. I have 30K miles on it and it brakes fine except for one situation. Full left turn, and the pedal goes to the floor. Oh yes, I have replace the master cylinder three times but finally figured out that it was always occurring with the full lock turn to the left. Last week, I swung around to park in a parking space on the other side of the road that was angled of course the opposite direction. Ended up knocking over a garbage can and jumping the curb. No damage done, but when I pressed that pedal to the floor, its always a panic situation.
Disc's on the front and drums on the rear. Dual master cylinder for disc / drum setup with 3 psi and 10 psi checks in the lines accordingly. Braking is very good. No power, manual brakes with a six to one lever setup.
No leaks in the system and reservoir was checked for fluid every time the problem happened. Always full to the top. Master cylinder located at frame level in the standard position.
Jack the front end up, rotate the wheel to full left lock and presto, you loose the pedal. Not so on a right lock turn. Never loose pedal during normal driving, only with a full left lock position. If you get close to left lock, you will start to loose the pedal but its right at the end of the wheel movement. DOT braided brake lines in front and no other flex lines in the system.
So both static (just sitting there) and rolling (1 mph) the problem will duplicate every single time.
Since I never have to fill the reservoir, fluid is not escaping the system. Something is swelling or expanding to take a good shot of fluid extra which leaves my pedal on the floor. 1" master cylinder.
the flex lines do not seem to be swelling or elongating.
Maybe someone has see this before. I searched the web and found comments on the flex lines causing the problem. One thing is for sure, the problem is repeatable every single time on a full left lock turn. Has never occurred in any other situation. Three mastercylinders later, the light bulb finally went off about the full left turn. Yea, it was every time it did it in the past. Logic said see if it will repeat static. Heck yes it will, every time.
I know its sounds impossible, but guys its doing it and its repeatable 100% of the time and only happens at full left lock turn.
give me some more ideas. For now, no full left turns, but that stinks.
