26Caliper Piston Removal
Remove the internal caliper o-ring from the outboard caliper half.
Place one of the caliper halves, piston side down, on a soft rubber
mat or a small section of inner tube on a flat surface.
Insert a rubber-tipped blow gun chuck nozzle into the banjo port.
CAUTION - EYE HAZARD
Wear safety glasses.
The caliper pistons may dislodge rapidly from the caliper, which
can lead to bodily injury or damage to the parts. Point the caliper
pistons toward a rubber surface before forcing air into the caliper.
While firmly pushing against the caliper half and chuck nozzle,
squeeze the air chuck to force air into the banjo port and dislodge
the pistons from the caliper.
Place a rag over the caliper to contain any fluid that may spray.
Continue to force air into the caliper until both pistons dislodge.
Do not remove one piston if the other is still seated.
Remove the pistons from the caliper.
Repeat this process for the other caliper half.
Use a pick to remove the piston seals from inside each caliper
body half. Install new seals inside each caliper body half.
NOTICE
Do not scratch the seal gland with a pick. It could result in a slow
fluid leak when the brake is applied.
