part number P10050 (PBR)

This is off the same aged falcons and have a 1" bore
you can also use the same aged Commodore cylinder as they also have a 1" bore (P10037 is the part number from memory....but will have to confirm that for you)


Just need to get the thread adaptors to suit as the falcons use imperial threads and the commodore use a 12mm primary port (sigma uses 10mm)


Just be careful with the proportioning of the brakes as there is alot more front brake bias in both these cylinders

thanks mate do u think they should be right with goin 4 pot calipers on the front with 324mm rotor?

depends on the piston size........4 pistons might be a bit much for the cylinder (unless you adapt an even bigger master......which could be done on later model falcon and commodres as they all run similar bodies and internals)

remember....your going from the cylinder designed for pushing 2 cylinders....not 8......




Where abouts are you located??????
if your nearby...i may be able to (personally) help you with the brakes as i used to work for PBR and gathered HEAPS of information from them
