Oliver OC-96 brakes question

[Doug424]

I just bought an OC-96 and the brakes are dead. I see the parts all look like standard automotive master and wheel cylinders. Does anyone know what truck parts might interchange with these?

[Robert Barbour]

I would take the parts you need to a heavy truck parts supplier and they should be able to match them.  The brake shoes can be relined. The wheel cylinders and master cylinder can usually be tacked by casting numbers.
