Bought a clutch and brake master cylinder rebuild kit for my 1961 Beach Car.

I probably ordered something wrong as the piston, seals and spring are very different to the original. They piston fits exactly though.



Can I use this kit or should I order a new one?

If I have to order a new one ,what should I ask for?

Thank you.

the modern rebuild kit for the older cylinders includes a replacement plunger to convert the old 1 ring, 1 cup type rubber seals to the modern 2 ring type.

it will fit and work fine.

Also, the brake master cylinder should have the three-legged white nylon, non-return valve. This goes in the cylinder first, so sits at the bottom of the cylinder (top -when it's fitted in the car)
