Girling Caliper Rebuild Kit, 12SP (GD528), does 1 Caliper

The "small" Girling 12SP caliper can be identified by the 1 11/16" (1.69", 43mm) diameter pistons and two bolts holding the caliper sections together. (The larger 14LF had 1 7/8" pistons and four bolts.)

The EPDM seals are formulated to work with any DOT-rated brake fluid (not for use with hydraulic oil). Each rebuild kit contains piston seals and dust seals for one caliper.
