Brake Caliper Anchor Plates

1.

Inspect the brake caliper anchor plates for damage, wear or corrosion. Clean with a wire brush as necessary.
- If the brake caliper anchor plate is damaged or worn, install a new brake caliper anchor plate. For additional information, REFER to Front Disc Brake for front brake caliper anchor plates or REFER to Rear Disc Brake for rear brake caliper anchor plates.

Brake Caliper Guide Pins

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.
1. 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.
2. 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.
3. Assemble the caliper seals, boots and guide pins. Use an ample amount of the specified grease to lubricate the bores and guide pins.
4. Inspect the brake pads. Refer to Brake System Inspection .

Brake Flexible Hose

NOTE: 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.

Inspect brake tubes for corrosion, cracks, leaks or any other signs of damage.
1. If a section of the brake tube is damaged, replace the entire section with a new tube of the same type, size, shape and length.
2. When installing the hydraulic brake tubing, hoses or connectors, tighten all connections to specifications. After installation, bleed the brake system. Refer to Brake System Bleeding .
Inspect the brake flexible hoses for cracks, leaks and swelling during brake application or any other signs of damage.
1. Install a new brake flexible hose if the hose shows signs of softening, cracking or other damage. REFER to Section 206-03, Brake Flexible Hose for the front brake flexible hose or REFER to Section 206-04, Brake Flexible Hose for the rear brake flexible hose.

Brake Master Cylinder

NOTE: During normal operation of the brake master cylinder, the fluid level in the brake master cylinder reservoir falls during brake application and rises during release. The returning brake fluid creates a slight turbulence in the master cylinder reservoir. This is a normal condition and indicates that the compensator ports are not clogged. Clogged compensator ports may cause the brakes to hang up or not fully release. The net fluid level (such as after brake application and release) will remain unchanged. Fluid level will decrease with pad wear.

NOTE: A trace of brake fluid will exist on the booster shell below the master cylinder mounting flange. This results from the normal lubricating action of the master cylinder bore and seal.

Inspect the brake master cylinder for fluid leaks.
1. Install a new master cylinder or brake fluid reservoir if signs of excessive leaking are present. REFER to BRAKE MASTER CYLINDER .
2. To check for correct brake master cylinder operation, Refer to Brake System .

Brake Booster

Inspect the brake booster for excessive corrosion or damage. Inspect the vacuum hoses for leaks and kinks.
1. Install a new brake booster if signs of excessive corrosion or damage is found. REFER to BRAKE BOOSTER .
2. Repair or replace vacuum hoses as necessary.
3. To check for correct brake booster operation, Refer to Brake System .
