Every 6-8 Weeks

• Release brakes.
• Check caliper movement. Measurement should be approximately 0.7mm.
• Inspect bellows and screw plugs for cracks, damage and proper seating and replace if necessary.

Every 26 Weeks

Step 1

BPW LIMITED RECOMMEND THIS INSPECTION IS CARRIED OUT EVERY 6 MONTHS OR EVERY PAD CHANGE

The lateral bearing play of the brake caliper guide pins can be checked using a dial gauge. Attach the dial gauge base to the axle beam and position the gauge facing the guide pin bearing on the lower edge of the cylinder mounting flange (see Figure 1).

Move the brake caliper from side to side radially from the centre of the axle (see Figure 2) and measure the total displacement. If the total amount measured on the gauge exceeds 1.5mm then the caliper guide pins and bushes must be replaced.

Step 2

• Release brakes.
• Remove brake pads.
• Check total slide movement ensuring pins have not seized.
• Inspect bellows and screw plugs for cracks, damage and proper seating and replace if necessary.
