Dry Master Cylinder - No Sign of Leak

[Bob Carriere]

All the M 37 Dodge I had usually lost most of the brake fluid over the Winter months..... every spring we filled and bleed the system..... never did find the leaks.

Just did my C15a....... flushed all the lines with fresh military surplus synthetic....... seesm the old stuff looses it purple color so it makes it easy to see the fresh fluid going out...... we used and extended reservoir with a tube throught the MC fill cap and used a manual suction device to pull out the old fluid...... than jacked all 4 wheels and adjusted the cams...... brake real good, hi and tight. The fluid had been in since the system was rebuilt over 5 years and due for a proper purging. Never had a leak....even after months in the sea container rarely needed to pump more than once.

Cheers
