Solution

1. Preparation

Gather necessary tools and replacement parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean cloth
Ensure the vehicle is off and the brakes are not engaged.
Remove the brake fluid reservoir cap.
Check the fluid level; if low, top off with the recommended brake fluid type (typically DOT 3 or DOT 4).
Clean the area around the reservoir before replacing the cap to prevent contamination.

3. Replace Worn Brake Pads and Rotors (if necessary)

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake pad spreader, and possibly a caliper tool.
Loosen the lug nuts on the wheel corresponding to the brake issue while the vehicle is still on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness; replace them if they are below the minimum recommended thickness (usually 3mm).
If rotors are scored or below the minimum thickness, replace them as well.
Remove the caliper bolts and slide the caliper off the rotor.
Replace the brake pads and/or rotors, ensuring to use the proper torque specs when reassembling.
Reattach the wheel and lower the vehicle.

4. Reset the Brake System

Tools Required: Diagnostic tool
Use a diagnostic tool to reset any fault codes related to the braking system.
Perform a brake system calibration if the tool supports this function.

5. Final Checks

Test the brake system by pressing the brake pedal several times to ensure it feels firm.
Check for leaks around the brake components.
Replace the wheel and torque the lug nuts to the manufacturer’s specifications.
