Rear disc brakes are a wonderful upgrade for the reliability of your sprite. Not only do you have the added safety of more braking power but you will no longer have to change leaking wheel cylinders. I never want to change rear wheel cylinders or adjust the rear brakes again. Disk brakes fit the bill, with modern calipers that are bullet-proof and self-adjusting. That's why you see this kit pictured below on my own personal Sprite, "Gumby."
These kits are available for knock off and bolt on wheels. They are a direct bolt on kit that you can do at home but it requires intermediate skill level. Tech support is also available for your or for your shop.
BEWARE-There are less expensive rear disk kits out there... we've tested them all and ours works best... it has a working hand brake and will also accommodate stock sprite radius arms. Call if you want to learn more!
We have done many of these conversions in our shop and would be happy to pick-up your car to perform this conversion (and to fix any other details needed to optimize your Sprite)...
We also have a kit available for later Sprites and Midgets with semi-elliptical leaf springs. Call!
