AU1 Master cylinder upgrade

[terryk]

HI All

I have fitted BA XR8 front brakes on the front and territory rear brake assembly they are great with the exception of the brake pedal feel due to the piston size increase in the calipers therefore requiring additional fluid from the master cylinder to move the piston the same amount. When I checked the PBR book the AU master cylinder is smaller than the BA, AU-PBR part# is B224-067 22.22mm/28.57mm verses BA PBR part# is B227-109 23.83mm/31.75mm. But the BA unit is slightly different.

After all that my question is what is the best way to go, can the AU unit be resized or can the BA unit do the job with a T for the pressure sw or something else??

Cheers
Terry
