AP Racing master cylinders have been developed with the benefit of our unparalleled experience in racing brake and clutch technology to respond to the severe demands encountered under competition conditions. 

AP Racing offer four Cylinder familes for the Stock Car Market. Two High Efficiency and Two Standard types, these cylinders are also widely used in all major race formula's throughout the world.Important:

All master cylinders are individually shimmed during manufacture to give a shorter cut off and less lost travel than equivalent production cylinders.

Therefore push rods, pistons and other internal components should not be switched between individual master cylinders.
