Installing Piston On Caliper
4. Install the piston assembly in the bore using Piston Ring Compressor Tool J-22629 or J-22639 as shown in the illustration. Use care not to damage
the seal lip as piston is pressed past the edge of the bore.
Inserting RTV Sealant Into Boot Groove
5. The boot groove on the piston is the groove closest to the concave end of the piston. Insert a bead of silastic sealant GM 1052366 or equivalent
into the boot groove in the piston and assemble the boot in the groove. The fold in the boot must face toward the end of the piston with the seal on
it.
6. Depress the pistons and check that they slide smoothly into the bore until the end of. the piston is flush with the end of the bore. If not, recheck
piston assembly and location of the piston spring and the seal.
Installing Boot Seal In Caliper
7. Position Boot Seal Installer Tool J-22628 or J-22638, over the piston and seat the steel boot retaining ring evenly in the counterbore as shown in
the illustration. The boot retaining ring must be flush or below the machined face of the caliper. Any distortion of uneven seating could allow
contaminating and corrosive elements to enter the bore.
