Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Wear safety goggles and gloves for protection.

2. Inspect and Top Off Brake Fluid

Locate the master cylinder reservoir under the hood.
Check the fluid level; if low, add the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Inspect for any signs of contamination (e.g., discoloration) and replace if necessary.

3. Check for Brake Leaks

Visually inspect all brake lines, hoses, calipers, and the master cylinder for signs of leakage.
If leaks are found, replace damaged components and recheck fluid levels.

4. Inspect Brake Pads and Rotors

Remove the wheel to access brake components.
Check brake pads for thickness (should be above 3mm) and look for uneven wear.
Inspect rotors for scoring or warping; replace if necessary.

5. Test Brake Booster

With the engine off, pump the brake pedal several times to release vacuum.
Hold the brake pedal down and start the engine; the pedal should drop slightly indicating proper booster function.
If the pedal does not drop, the brake booster may need replacement.

6. Bleed the Brake System

If air is suspected in the brake lines, bleed the brakes using the following steps:
1. Start at the wheel farthest from the master cylinder (typically the rear passenger side).
2. Attach a clear hose to the bleeder valve and submerge the other end in a container with brake fluid.
3. Open the bleeder valve and have an assistant pump the brake pedal until fluid flows without bubbles, then close the valve.
4. Repeat for each wheel in order (rear passenger, rear driver, front passenger, front driver).
