Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear appropriate safety gear (gloves, safety glasses).

2. Check and Refill Brake Fluid

Locate the brake master cylinder reservoir.
If the fluid level is low, remove the cap and add the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Replace the cap securely after refilling.

3. Inspect and Replace Brake Pads

Remove the wheel to access the brake assembly using a socket set.
Inspect the brake pads for thickness; replace if they are worn down to 3mm or less.
To replace pads:
- Remove the caliper bolts and lift the caliper off the rotor.
- Replace the old pads with new ones, ensuring proper alignment.
- Reinstall the caliper and torque the bolts to the manufacturer's specifications.

4. Check Brake Lines and Components

Inspect all visible brake lines for cracks or leaks.
Tighten any loose connections and replace damaged lines as necessary.
Ensure that all fittings are secure and there are no signs of fluid leaks.

5. Test Brake Switch

Locate the brake switch at the top of the brake pedal.
Disconnect the switch connector and use a multimeter to check for continuity when the brake pedal is pressed.
Replace the switch if it fails the continuity test.
