Hi Guys

First Peter excellent overhaul, restoration, or preventive maintenance program, definitely setting the Jeep up for another 50 years.

It would be interesting to check the hardness of NOS 1940s brake washers vs New 2020s washers. I suspect that the percentage of recycled copper is making the washers harder to the point where they no longer deform to seal well. At the same time has any one notice that new manufacturer brake cylinders the circular groves the washer are to fit against and deform to seal are not as sharp.

Jumping to old fix for washer and cylinders that doesn't seal. Clean a copper washer then heat and apply solder wipe off excess. I have even use this trick when only had a used washer to finish a brake job.

The suggestion to grab true NOS washers whenever you chance on them is a good one.

Cheers Phil
