Solution

1. Preparation

Gather tools and parts needed for repairs.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to ensure safety while working on the electrical components.

2. Brake Fluid Check and Replacement

Sub-steps:
1. Inspect the brake fluid reservoir and confirm the fluid level.
2. If low, top up with the recommended brake fluid (DOT 3 or DOT 4).
3. If the fluid is contaminated, perform a brake fluid flush.
Tools Required: Brake fluid, funnel, turkey baster (if necessary for old fluid removal).

3. Brake Pad Inspection and Replacement

Sub-steps:
1. Remove the wheel to access the brake caliper.
2. Inspect the brake pads for wear; they should be at least 1/4 inch thick.
3. If worn, remove the caliper bolts and slide the caliper off the rotor.
4. Replace the brake pads with new ones, ensuring the correct orientation.
5. Reinstall the caliper and tighten bolts to the manufacturer’s torque specifications.
Tools Required: Socket set, torque wrench, brake pad spreader.
Safety Warning: Always wear safety glasses and gloves while handling brake components.

4. Rotor Inspection and Resurfacing/Replacement

Sub-steps:
1. Check the rotor surface for grooves or warping using a dial indicator.
2. If damaged, either resurface the rotors if within specifications or replace them with new ones.
3. Clean the rotor surface with brake cleaner before reinstallation.
Tools Required: Dial indicator, brake cleaner.

5. Brake Line Inspection and Repair

Sub-steps:
1. Visually inspect the brake lines for cracks, corrosion, or leaks.
2. If leaks are found, replace the damaged section of the brake line.
3. Ensure all connections are tight and secure.
Tools Required: Line wrench, replacement brake line.
