Brake Master Upgrade

[Kaido_RR]

Hi,

I think its about time i upgrade my brake master cylinder, Im running AP Racing CP5200 calipers on the front. running std r33 gts-t (non-abs) master. I was thinking about upgradeing to the R32 GTR VSPEC 2 master but im not happy to pay over $500 from nissan for a stock item.

I have been looking on the AP website and they sell alot of masters, i was wondering if anyone would be able to put me in the right direction on what would be best for my application and what i would need to make it fit?

CP2623 - A compact flanged mounted Master Cylinder suitable for all brake and clutch applications especially where the space is restricted. Short travel to cut-off is standard, extra short cut-off also available. 10 bore sizes from 14.0mm to 25.4mm. Hydraulic threads are Imperial.

CP6465 - A new concept in Master Cylinder design. This cylinder operates on the Pull rather than Push principle of other cylinders. It has a built in trunnion mounted needle roller bearings for direct mounting to balance the bar. The ultimate in master cylinder efficiency. Metric threads.

CP6093 - A Master Cylinder suitable for most brake and clutch applications where space restrictions are not a primary consideration. the longer available stroke makes it particularly suitable for some clutch installations. Long thread potion allows the push rod length cut to suit. 8 bore sizes from 15.9mm - 25.4mm. Supersedes CP2293 Master Cylinder family.

CP5854 - A new high efficiency single circuit, short push type Master Cylinder. Fixed through a trunnion system running in needle roller bearings and with a one piston/push rod it offers a significant improvement in efficiency over traditional Master Cylinder designs. Full range of 10 bore sizes. Imperial threads.

CP5855 - A new high efficiency single circuit, short push type Master Cylinder. Fixed through a spherical bearing and with a one piece piston/push rod it offers a significant improvement in efficiency over traditional Master Cylinder designs. Full range of 10 bore sizes. Imperial threads.
