Dual Master Cylinder 7/8" (thru '62)

This is the best master we have found and what we use on all the cars that come through our shop.

This product has a 7/8 bores just like the stock master. We use this master on both disc and drum brake cars. Some people like to use a 3/4 bore master when changing to front disk brakes in a Bugeye, but we prefer 7/8 for both drum and disk, primarily because we find the 3/4 bore master makes the brake pedal too spongy. I have used a 7/8 master on Gumby with disc brakes since 1979, and prefer the quick and firm pedal action of that set up and I believe you will too. 

This is a great quality direct replacement for your old leaky / worn out dual master. We have had good longevity with this replacement and have field tested it on many Sprites.

Our reproduction master cylinders come with an aftermarket plastic reservoir cap as shown. If you wish to retain the factory-correct look of the metal fluid cap, you will have to re-use the cap from your old master cylinder, as they are no longer reproduced. Installation Note: When removing & installing the master cylinder, it is strongly recommended to use a crow foot wrench due to the tight clearances present on the line connections. It is very difficult to get a tight seat when using a traditional wrench.

Installer's Note: Check the length of your push rods before installing the new master cylinder!!! 2 different lengths of push rods were used depending on the size of the bore of the master and it's impossible to know who has installed what over the years. The correct push rod length for the 7/8" master is 4 1/8". If you find your car has shorter (about 3 11/16" or so) push rods installed, we offer the longer rods for sale here.
