Solution

1. Preparation

Gather tools and parts before starting.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Wear safety glasses and gloves.

2. Check Brake Fluid Level

Open the hood and locate the master cylinder.
Remove the cap and check the fluid level; add DOT 3 or DOT 4 brake fluid if low.
Inspect for signs of contamination in the fluid.

3. Inspect for Leaks

Visually inspect all brake lines and hoses for any signs of leaks or corrosion.
If leaks are found, replace the damaged lines or hoses.
Tighten any loose fittings as required.

4. Examine Brake Components

Remove the wheels to access the brake calipers and rotors.
Inspect brake pads for thickness; replace if worn below specifications (typically 3mm).
Check the rotors for grooves or warping; machine or replace as necessary.

5. Test Brake Booster

With the engine off, press the brake pedal several times to deplete the brake booster vacuum.
Start the engine and check if the brake pedal feels firmer and returns to normal height.

6. Bleed the Brake System

If air is suspected in the brake lines, bleed the brakes using a two-person method or a brake bleeder tool.
Start with the wheel furthest from the master cylinder, typically the rear right corner, and work towards the closest.
Keep the master cylinder reservoir topped up during the process.
