Dis-assembly/reassembly

1. Slacken the two fastening screws and remove the brake caliper with its pads.

NOTE: When refitting change the caliper fastening screws and tighten them to the specified torque.

31 ÷ 38 Nm
3.1 ÷ 3.9 kgm

WARNING: When refitting check that the rubber boots protecting the fastening pin threads are intact, if not, change them. When refitting the brake pad with the wear sensor, it must be fitted on the inner side of the disk (brake caliper piston side): also check that the relief on the outer part of the same pad is positioned to the rear of the direction of travel.

When refitting bleed the air from the brake system (see specific paragraph).

DIS-ASSEMBLY/REASSEMBLY

1. Disconnect the hose connection from the caliper.
2. Remove the relief screw.

15 ÷ 19 Nm
1.6 ÷ 1.9 kgm

4 ÷ 6 Nm
0.4 ÷ 0.6 kgm

1. Blow a jet of compressed air into the brake fluid inlet hole to bring the piston out.
2. Remove the piston (2A), seal (2B) and the protective boot (2C).

CHECKS AND INSPECTIONS

• The piston and caliper body must not reveal signs of abrasion or seizing; if they do, change the caliper complete with piston.
• Always change the protective boot and seal.
• Make sure that the relief screw is not clogged.
• Check the hose for swellings and cracks.
• Change the brake pads if the thickness of the friction material is below 1.5 mm.
• Check the brake caliper support bracket for cracks and distortion.

CHANGING THE FRONT BRAKE PADS

• Remove the front wheel.

1. Disconnect the electrical connection of the brake pad wear sensor.
2. Slacken the upper screw fastening the caliper body.

31 ÷ 38 Nm
3.1 ÷ 3.9 kgm
