Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and ensure it is in "Park" mode.
Disconnect the battery for safety.

2. Check and Replace Brake Fluid

Sub-steps:
1. Locate the master cylinder reservoir.
2. If the fluid level is low, add the recommended brake fluid (DOT 3, DOT 4, or manufacturer specified).
3. If the fluid is contaminated (dark or dirty), proceed to flush the system.
Tools Required:
- Brake fluid
- Funnel
- Shop towels

3. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for thickness; replace if less than 3mm.
3. Check rotors for scoring or warping; replace if necessary.
4. Inspect brake calipers for leaks; replace if damaged.
5. Reassemble components and torque lug nuts to the manufacturer's specifications.
Tools Required:
- Socket set
- Torque wrench
- Brake cleaner

4. Bleed the Brake System

Sub-steps:
1. Connect a brake bleeder kit to the brake caliper.
2. Have an assistant pump the brake pedal and hold it down.
3. Open the bleeder valve to allow air and fluid to escape, then close it before the pedal is released.
4. Repeat until no air bubbles are visible in the fluid.
5. Check and top off the brake fluid reservoir.
Tools Required:
- Brake bleeder kit
- Wrench for bleeder valve
