Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, brake fluid bleeder kit
Sub-steps:
1. Locate the brake fluid reservoir and remove the cap.
2. If the fluid is dark or contaminated, use a clean funnel to drain the old fluid.
3. Refill the reservoir with the manufacturer's recommended brake fluid type.

3. Bleed the Brake System

Tools Required: Brake fluid bleeder kit, clear tubing
Sub-steps:
1. Start at the wheel farthest from the master cylinder (usually the right rear).
2. Attach the clear tubing to the bleeder valve on the brake caliper.
3. Open the bleeder valve and have an assistant pump the brake pedal until no air bubbles appear in the tubing.
4. Close the bleeder valve and repeat for each wheel in the following order: right rear, left rear, right front, left front.
5. Ensure the brake fluid reservoir remains filled during the process to prevent air from entering.

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

Tools Required: Socket set, torque wrench, jack stands, brake cleaner
Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect the brake pads for thickness and replace if they are below the minimum thickness.
3. Check the brake rotors for scoring or warping; replace if necessary.
4. Install new brake pads and rotors, ensuring they are properly seated.
5. Torque the caliper bolts to manufacturer specifications.

5. Reassemble and Test

Tools Required: Torque wrench
Sub-steps:
1. Reinstall the wheel and torque the lug nuts to the manufacturer's specifications.
2. Lower the vehicle and pump the brake pedal to ensure a firm feel.
3. Test drive the vehicle at low speeds to check for proper braking response and firmness.
