Solution

1. Preparation

Gather all necessary tools and parts.
Safety equipment: Gloves and safety goggles.
Disconnect the battery to avoid electrical shorts.

2. Check Brake Fluid Level

Locate the master cylinder reservoir.
Remove the cap and inspect the fluid level.
If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4, depending on the vehicle specifications).

3. Inspect Brake Pads and Rotors

Remove the wheel to access the brake assembly.
Visually inspect the brake pads for thickness; replace if less than 3mm.
Check the rotors for grooves or warping; if damaged, replace them.
Use a caliper tool to measure rotor thickness and ensure it meets manufacturer specifications.

4. Examine Brake Lines and Hoses

Visually inspect all brake lines and hoses for signs of wear or leaks.
If any leaks are found, replace the affected line or hose.

5. Test Brake Booster

With the engine off, press the brake pedal several times to deplete any vacuum.
Start the engine; the brake pedal should feel firmer after a few seconds.
If it remains soft, the brake booster may be faulty and should be replaced.

6. Replace Brake Warning Switch (if necessary)

Locate the brake warning switch, typically found near the master cylinder or on the brake pedal assembly.
Disconnect the electrical connector and remove the switch.
Install the new switch and reconnect the electrical connector.
