Brake Calipers
1. Inspect the brake calipers for leaks, damage to seals, and piston corrosion or binding.
-
If the brake caliper is leaking or otherwise damaged, install a new brake caliper.
Brake Caliper Guide Pins

Brake Caliper Guide Pins
1. The guide pins should slide with a reasonable amount of hand force. If the brake pads show taper wear or the guide pins are difficult to move,
carry out the following steps.
-
Disassemble the brake caliper guide pins and inspect the guide pins and guide pin bores for wear, damage and corrosion. If bore is worn or
damaged, replace the damaged component.
-
Use a wire brush, rolled-up sandpaper or emery cloth to remove all corrosion and foreign material from the caliper guide pin bores. Clean any
remaining foreign material from the bores with brake parts cleaner and compressed air.
-
Assemble the caliper guide pins using new caliper seals, boots and guide pins. Use an ample amount of the specified grease to lubricate the
bores and guide pins.
-
Inspect the brake pads. For additional information, refer to Brake System Inspection.

Brake Flexible Hoses and Tubes
NOTICE: Never use copper tubing. It is subject to fatigue, cracking and corrosion, which may result in brake tube failure.
NOTE: Double-wall steel tubing is used throughout the brake hydraulic system. All brake tube fittings must be correctly double flared to provide strong,
leakproof connections. When bending tubing to fit the underbody or rear axle contours, be careful not to kink or crack the tube.
1. Inspect brake tubes for corrosion, cracks, leaks or any other signs of damage.
-
If a section of the brake tube is damaged, the entire section must be installed with a new tube of the same type, size, shape and length.
