Early Morris Minors ('48-'62) and Bugeye Sprites (1958-1961) used single piston rear wheel cylinders. These are noted externally by having the brake adjuster through the wheel rather than on the backplate. There is one per wheel but we recommend replacing them in pairs.

These cylinders have 7/8" bores, the later type RBK106's (Morris Minors only) have 3/4" bores - they are basically interchangeable as long as both are replaced at a time.

Morris Minors and all drum brake equipped Sprites have what are known as dual leading shoe brakes on the front, this means that there is an individual wheel cylinder for the leading edge of each shoe. The two cylinders for the right front wheel (FBK105) are the same and the two for the left (FBK106) are mirrors of the right. These fit the fronts of Morris Minors from 1954-71.

Two (2) are required for the right front.
