Master cylinder repair kit (late 1951 onwards).

Master cylinder repair kit (late 1951 onwards).

For later ACs (late 1951 onwards) with the all hydraulic braking system.

For master cylinder with 3/4" bore diameter.

Kit includes seals, rubber boot, copper washer, spring, shim washer and circlip.

I recommend that red rubber grease be applied inside the rubber dust boot, after assembly of the cylinder. It helps to keep out water and dust. The plunger should only be lubricated with clean brake fluid.
