Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Wear safety glasses and gloves for protection.

2. Inspect and Replace Brake Fluid

Locate the Brake Fluid Reservoir: Find the reservoir, typically located near the back of the engine bay.
Check Fluid Level: If the fluid is below the minimum line, proceed to the next step.
Remove Old Brake Fluid: Use a turkey baster or siphon to remove old fluid from the reservoir.
Add New Brake Fluid: Fill with the manufacturer-recommended brake fluid (DOT 4 or DOT 5.1, as specified in the owner's manual) up to the maximum line.
Seal the Reservoir: Ensure the cap is securely fastened after filling.

3. Replace Brake Pads (if worn)

Lift the Vehicle: Use a jack to raise the front or rear of the vehicle, depending on where brake pads need replacement.
Remove Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Remove Caliper: Unbolt the caliper using the appropriate socket size, and carefully hang it using a bungee cord (do not let it hang from the brake line).
Replace Brake Pads: Remove old pads and install new ones, ensuring they are correctly positioned.
Reattach Caliper: Bolt the caliper back into place, ensuring it is secured to the manufacturer’s torque specifications (typically around 25-30 Nm).
Reinstall Wheel: Put the wheel back on, hand-tighten the lug nuts, then lower the vehicle and torque the nuts to the recommended specifications (usually 90-110 Nm).

4. Check Brake Light Switch

Locate the Brake Light Switch: Typically found near the brake pedal.
Inspect Wiring: Ensure that the wiring is intact and connected properly.
Test the Switch: Use a multimeter to check for continuity when the brake pedal is pressed. Replace if faulty.
