Solution

1. Preparation

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

2. Inspect and Replace Brake Fluid

Sub-steps:
- Open the hood and locate the brake master cylinder reservoir.
- Remove the cap and check the fluid level; if low, top it off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
- If the fluid is dark or contaminated, perform a complete brake fluid flush.
Tools Required: Brake fluid, funnel, turkey baster (for fluid removal).

3. Check for Leaks

Sub-steps:
- Inspect all brake lines, hoses, and connections for signs of leakage.
- If any leaks are found, replace the damaged lines or hoses.
Tools Required: Wrench set, brake line flaring tool (if needed).

4. Inspect Brake Components

Sub-steps:
- Remove the wheel to access the brake calipers and pads.
- Check the brake pads for thickness; replace if worn down to 3mm or less.
- Inspect the rotors for any signs of damage; resurface or replace if necessary.
Tools Required: Jack and jack stands, lug wrench, socket set.

5. Bleed the Brake System

Sub-steps:
- Start at the wheel farthest from the master cylinder (usually the right rear) and work towards the closest (left front).
- Connect a clear hose to the bleeder valve on each caliper, submerging the other end in a container with brake fluid.
- Have an assistant pump the brake pedal several times, then hold it down while you open the bleeder valve to release air.
- Repeat until no air bubbles are present in the fluid.
- Ensure to top off the brake fluid reservoir as needed during the process.
Tools Required: Brake bleeder kit or clear hose, container for fluid, wrench for bleeder valves.
