Kelsey Hayes

I finally built up enough courage to tackle the Kelsey Hayes brake booster today.

It stripped down very easily and was in good condition apart from some scoring on the central shaft. Fortunately this was easily fixed with some gentle linishing in the lathe.

The rest of the assembly was easy given that I'm used to servicing scuba equipment.

For good measure I painted the brake and clutch cylinders with caliper paint as well.
