Hydraulic clutch master for GTD. Part number?

[Eric Johnson]

My hydraulic clutch master cylinder is shot. It's a Girling unit with "70" inscribed on it. Where can I get a replacement?

Thanks!

Hi Eric

There are plenty of suppliers in England such as Merlin Motorsport, Raceparts & Europa but if you want to source one in the States try a Land Rover agent. The "70" refers to .70". I think the Land Rover uses a .75" which would do at a pinch.
I think they were also fitted to a lot of older British road and racecars so you may find a source there.

Eric, if this is a fairly standard GTD the 0.7 diameter will not give enough throw on the 28mm dia slave, all GTDs originally ran 0.75 inch cylinders, and we up size those to larger bore if the throw is insufficient to get clutch clearances. FRANK

Cheapest source I found when building mine was

Professional Motorsport Parts, Spares & Rally Equipment from Rally Design

Eric,
The easiest U.S. source is probably Pegasus Racing. Girling cylinders with integral reservoirs are $115 and remote reservoirs ones $90. The recommendation for a .75" cylinder is smart. Order online at pegasusautoracing.com
