Cleaning and Inspection

If a visual inspection does not adequately determine the condition of the lining, a physical check will be necessary. To check the amount of lining wear, remove the wheel and tire assemblies, and the calipers.

Remove the rear disc brake pads.

The combined brake pad and lining material thickness should be measured at the thinnest part of the assembly.

When a set of brake pads are worn to a total thickness of approximately 3.0 mm they should be replaced.

Replace both brake pad assemblies (inboard and outboard). It is necessary that both rear wheel sets be replaced whenever brake pad assemblies on either side are replaced.

If the brake pad assemblies do not require replacement, reinstall the assemblies making sure each is returned to the original position.

CALIPER INSPECTION
Check for brake fluid leaks in and around boot area and inboard lining, and for any ruptures, brittleness or damage to the piston dust boot. If the boot is damaged, or a fluid leak is visible, disassemble caliper assembly and install a new seal and boot, and piston if scored.

Check the guide pin dust boots to determine if they are in good condition. Replace if they are damaged, dry, or found to be brittle.
