Removal

WARNING: Do not use any fluid other than clean brake fluid meeting manufacturer's specification. Additionally, do not use brake fluid that has been previously drained. Following these instructions will help prevent system contamination, brake component damage and the risk of serious personal injury.

WARNING: Carefully read cautionary information on product label. For EMERGENCY MEDICAL INFORMATION seek medical advice. In the USA or Canada on Ford/Motorcraft products call: 1-800-959-3673. For additional information, consult the product Material Safety Data Sheet (MSDS) if available. Failure to follow these instructions may result in serious personal injury.

NOTICE: Do not spill brake fluid on painted or plastic surfaces or damage to the surface may occur. If brake fluid is spilled onto a painted or plastic surface, immediately wash the surface with water.

1. Check the brake fluid level in the brake master cylinder reservoir.
- If required, remove the fluid until the brake master cylinder reservoir is half full.

2. Remove the wheel and tire.

3. NOTICE: Do not pry in the caliper sight hole to retract the pistons, as this can damage the pistons and boots.

NOTICE: Do not allow the brake caliper to hang from the brake hose or damage to the hose can occur.

Remove the 2 brake caliper bolts and position the caliper aside.
- Support the caliper using mechanic's wire.

4. WARNING: Always install new brake shoes or pads at both ends of an axle to reduce the possibility of brakes pulling vehicle to one side. Failure to follow this instruction may result in uneven braking and serious personal injury.

Remove the 2 brake pads and the retraction clips.
- Discard the retraction clips.

5. Measure the brake disc thickness, machine if necessary.
- Install a new brake disc if it is not within specification. For additional information, refer to Brake Disc .
