Solution

1. Preparation

Tools Required: Socket set, brake fluid, cleaning cloths, OBD-II scanner, brake pad gauge.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues while working on the braking system.

2. Inspect Brake Fluid

Locate the brake fluid reservoir under the hood.
Check the fluid level; if it is below the minimum mark, top it off with the manufacturer's recommended brake fluid type.
Inspect for any leaks around the reservoir and brake lines.

3. Replace Brake Pads (if worn)

Tools Required: Socket set, torque wrench, jack stands, lug wrench.
Loosen the lug nuts on the wheel, raise the vehicle using a jack, and secure it with jack stands.
Remove the wheel and inspect the brake pads using a brake pad gauge.
If pads are worn down (below 3mm), remove the caliper bolts and slide the caliper off.
Replace old pads with new ones, ensuring they are installed correctly.
Reinstall the caliper and torque the bolts to the manufacturer's specifications.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are warped or excessively worn, remove the caliper as described above.
Remove the rotor retaining screws, if applicable, and slide the rotor off the hub.
Install a new rotor, ensuring it is seated properly.
Reinstall the caliper.

5. Final Checks

Refill the brake fluid reservoir to the appropriate level if it was low.
Reconnect the battery.
Check the brake pedal feel; it should be firm and responsive.
