1967 Flavia Coupe - Brake Slave Cylinder

[Angle Grinder]

1967 Flavia Coupe 1.8

I've been getting my Slave Cylinder rebuilt and we've hit a problem and require a replacement piston for the part shown in the attached picture?

Can anyone sell me this part or even sell me a complete slave cylinder that is in need of a rebuild?

When rebuilding the cylinder we were working with a workshop manual and it suggested that the seal for the rear braking system piston sould be the same as the one for the front piston (seal 7 in the kit). My machine shop chum worked to the manual and machined the piston to take the seal supplied in the kit, but this has resulted in the rear brakes coming on with a sharpness that causes them to lock up at a touch of the pedal.

So I need an original piston to allow us to rebuild the brakes in the same manner as they came apart. Yeah, I know, don't ask. He's a nice guy and thought he was doing me a favour! Roll Eyes

P.S. I need to get the car back together before the 5th July as a friend wants to use it as a wedding car!!!  Undecided
