3502012 Brake Caliper Pin Bushing Ø 39mm

What does a brake caliper pin bushing do?

This brake caliper pin bushing serves as a critical component within the air disc brake caliper assembly. By providing a stable interface between the pin and the caliper body, it prevents excessive vibration and ensures the piston applies even pressure to the brake pads. It is manufactured from high-strength components to withstand the intense thermal and mechanical stresses found in heavy-duty braking environments.

Compatibility and fitment

This component is designed for specific SB6 and SB7 caliper series. Its precise Ø 39 mm diameter ensures an exact fit to maintain the necessary clearance for smooth sliding motion. It is compatible with various heavy commercial vehicle braking systems that utilize this specific pin dimension to prevent uneven pad wear.

Installation and maintenance

For optimal performance, technicians should inspect bushings during every brake service for signs of uneven wear or deformation. Proper lubrication with high-temperature grease is essential to maintain movement and prevent seizing. Always follow the vehicle manufacturer's service manual for specific installation clearance and torque requirements during replacement.

Troubleshooting and service

Regular maintenance of the pin and bushing assembly helps prevent brake drag and ensures consistent braking performance across the vehicle's service life.
