Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect and Refill Brake Fluid

Sub-steps:
1. Open the hood and locate the brake master cylinder reservoir.
2. Check the brake fluid level; if low, top it off with the recommended brake fluid type (usually DOT 3 or DOT 4).
3. If the fluid is dirty or has debris, plan to flush the brake system.

3. Inspect Brake Lines and Hoses

Sub-steps:
1. Visually inspect all brake lines and hoses for any signs of leaks or damage.
2. If leaks are found, replace the damaged lines or hoses.
3. Use a wrench to tighten any loose connections.

4. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
1. Lift the vehicle and secure it with jack stands.
2. Remove the wheel to access the brake assembly.
3. Remove the caliper bolts and lift the caliper off the rotor. Support it to avoid straining the brake line.
4. Remove the old brake pads and inspect the rotor for wear; replace if the thickness is below specifications.
5. Install new brake pads and reassemble the caliper.
6. Torque caliper bolts to manufacturer specifications (usually around 20-25 lb-ft).

5. Bleed the Brake System

Sub-steps:
1. Start with the brake farthest from the master cylinder (typically the right rear).
2. Use a brake bleeder kit or a hose attached to the bleeder valve and submerge the other end in a container with brake fluid.
3. Have an assistant pump the brake pedal several times and hold it down.
4. Open the bleeder valve to allow fluid to flow out, then close it before your assistant releases the brake.
5. Repeat until no air bubbles are visible in the fluid.
6. Repeat on other brake lines in the correct order: right rear, left rear, right front, left front.
