I have a couple questions about a 1966 H20E 3 wheeler with a Y112 engine.

1. On the floor board, right side, there is a T handle pull cable.
It is associated with the brake system.....
What does it do and how does it work??

2. The hydraulic filter cartridge is Hyster P/N 236090 and
the gasket is 236088.

Can anyone cross the Hyster numbers to a more common brand of replacement cartridge number?
Baldwin? Purolator? Fram?

Thank You!
