Title: Gemini Brake Booster Post by: Burnsy on June 06, 2004, 08:22:26 AM Can anyone fill me in on Gemini brake boosters, I am looking at one for my EK but anyones infor from their FE-FC conversion would be a great help. Questions that spring to mind are:
Are the gemini units dual circuit? If so, what size rear slaves do I need? Can I bolt a gemini booster and master straight up for Torri disks or do I need a different master? Mike Title: Re: Gemini Brake Booster Post by: Burnsy on June 06, 2004, 08:33:49 AM Just another thought, does anybody know what size EK rear slaves are and are they the same as the front? I seem to recall reading somewhere that the FB and EK cylinders where a different size to FE and FC's?

I've seen this conversion done to a EH Holden. He used a Gemini Booster and Dual circuit master cylinder connected to Torana front discs with 9/16 rear wheel cylinders. FE-EK front wheel cylinders are 1 3/16'' FE-EK rear wheel cylinders are 1 1/16'' FE-FC rear brake cylinders are not interchangeable with FB-EK as they have a different brake pipe size. Hope this helps, Regards ACE 8) Title: Re: Gemini Brake Booster Post by: Digger on June 07, 2004, 09:07:04 AM Burnsy,
When using the Gemini booster it is best to run a F##d XB master cylinder I think they are a 1" bore. Hope it helps, Steve. Title: Re: Gemini Brake Booster Post by: Sarge on June 07, 2004, 10:05:07 AM Burnsy,
I am running Commodore disc brakes both front and rear. I am using TE Gemini booster and master cylinder. Just made my own brake line's to suit. Hope this is of some help to you. Regards Sarge Title: Re: Gemini Brake Booster Post by: Burnsy on June 08, 2004, 09:18:20 AM Can anyone tell me the diameter of the gemini booster, my EK is Auto and it doesnt have much room between the master cylinder and the bonnet hinge - only 65mm to the centre of the cylinder to be precise :-/, may have to go back to the VH40 option.
Why is it better to use a one inch Fxxx master cylinder if Sarge is able to run front and rear disks off a gemini master, why change it? After all who likes to contaminate their Holden if they don't have too!!! Title: Re: Gemini Brake Booster Post by: Effie C on June 08, 2004, 09:36:06 AM V6 conversions use the crummydore booster in FE FC'sand the gemini booster in FB EK's. Check out their site as it contains some info.
