Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and securely raise it using jack stands.
Disconnect the battery for safety.

2. Inspect and Repair Brake Lines

Sub-steps:
1. Visually inspect the brake lines for signs of corrosion, leaks, or damage.
2. If leaks are found, replace the damaged section of the brake line using a flare tool to create proper fittings.
3. Bleed the brake system to remove air pockets using a brake bleeder kit.

3. Check and Replace Rear Brake Components

Sub-steps:
1. Remove the rear wheels to access the brake components.
2. Inspect the rear brake pads and rotors for wear; replace if thickness is below specifications.
3. If calipers are seized or leaking, replace the calipers with new units.
4. Reassemble all components and ensure all fasteners are torqued to manufacturer specifications.

4. Refill and Bleed Brake Fluid

Sub-steps:
1. Refill the master cylinder with fresh brake fluid (DOT 3 or DOT 4 as specified).
2. Bleed the rear brakes starting from the furthest caliper from the master cylinder, ensuring no air remains in the lines.
