1. Bleed Screw - Remove


2. Piston - Remove
1.
Adjust the brake caliper piston compressor (A) so that the clearance between the plate (B) of the brake caliper piston compressor and each of the outer and inner pistons is 10 mm (0.39 in) or so.
2.
Hold the brake caliper piston compressor so that equal force is applied by the plate to the two outer pistons and two inner pistons and the clearance between the plate and each of the inner and outer pistons is equal.
3.
Blow out the pistons (A) with compressed air gradually, and remove the pistons from the caliper body.
NOTE: Blow out the four pistons until they come in contact with the plate of the brake caliper piston compressor.
4.
Repeat steps 1 to 3 several times until all the pistons are completely removed.
NOTE: Do not put your hand into the caliper body because the pistons will come out forcibly from the caliper body.

1.
Lift the piston boots (A) with the tip of a screwdriver or a similar tool.
