Free brake pedal travel/minor,major adjustments?

[Fernando Mendes]

My 1952 B3-B truck is leaking in the boot in the floor garage,when it is stopped,after I drove it.I was thinking it was possible the free pedal travel and turned counterclockwise the piston push rod.It minimizes the leaking a days,but now it is leaking again.What can I check now?

Sounds like its time to replace the master cylinder unless you have recently replace the hydraulic parts of the brake system. With these single master cylinder its safer to replace the defective part.
