Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lift the vehicle using jack stands.
Disconnect the battery to prevent any electrical issues during repair.

2. Inspect and Repair Brake Lines

Sub-steps:
1. Remove the wheel to access brake components.
2. Inspect the brake lines for any signs of wear or leaks.
3. If leaks are found, replace the affected brake lines with new ones.
Tools Required: Brake line wrench, socket set.

3. Bleed the Brake System

Sub-steps:
1. Refill the master cylinder with fresh brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
2. Start bleeding the brakes at the furthest wheel from the master cylinder (usually the right rear).
3. Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valve.
4. Repeat for each wheel in the correct order (right rear, left rear, right front, left front).
Tools Required: Brake bleeder kit, clear tubing, brake fluid.

4. Inspect and Replace Brake Pads/Rotors (if necessary)

Sub-steps:
1. If brake pads are worn beyond the manufacturer’s specifications, remove the caliper and replace the pads.
2. Inspect rotors for warping or excessive wear; replace if necessary.
3. Reassemble the components ensuring all bolts are torqued to specifications.
Tools Required: Torque wrench, socket set.
