13/16 Primary Seal Change

Our common 13/16" primary master cylinder seal is no longer available and the replacement is not interchangeable, this will result in AP Racing not being able to supply the repair kit CP2623-93RK any longer.

New Seal Information.
The new seal is narrower than the old requiring a new piston. Some customers may choose to buy new master cylinders which in future will be built with the new seal and new piston with geometry to suit.
