Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues while working on the brake system.

2. Brake Pad Replacement

Sub-steps:
1. Remove the wheel using a socket set.
2. Disconnect the brake caliper by removing the caliper bolts and hanging it securely without straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Apply brake grease to the backing of the new brake pads.
5. Install the new brake pads into the caliper bracket.
6. Reinstall the brake caliper and torque the caliper bolts to the manufacturer's specifications (typically around 20-25 ft-lbs).
7. Repeat for the other side if necessary.

3. Brake Fluid Replacement

Sub-steps:
1. Remove the brake fluid reservoir cap.
2. Use a turkey baster to remove old fluid from the reservoir.
3. Refill the reservoir with new brake fluid (DOT 3 or DOT 4 as specified).
4. Bleed the brakes using the two-person method or a brake bleeder kit to ensure no air is in the system.
5. Check the fluid level again and top off if necessary, then replace the cap securely.

4. Brake Line Inspection and Repair

Sub-steps:
1. Inspect all brake lines and hoses for signs of wear, corrosion, or leaks.
2. If damage is found, use a line wrench to disconnect the damaged section.
3. Replace with a new brake line, ensuring proper routing and securing.
4. Bleed the brake system again after replacing any lines to remove air.
