Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, torque wrench, safety goggles, gloves.
Safely park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Brake Pads and Rotors

Loosen and remove the wheel lug nuts using a lug wrench.
Lift the vehicle with a jack and secure it on jack stands.
Remove the wheel to access the brake assembly.
Visually inspect brake pads for thickness; replace if they are worn below 3mm.
Check brake rotors for wear; use a micrometer to measure thickness and compare it to manufacturer specifications. Replace if warped or below minimum thickness.

3. Replace Brake Pads or Rotors (if necessary)

If pads are worn, remove the caliper bolts using a socket set.
Slide the caliper off the rotor and support it with a bungee cord to avoid strain on the brake line.
Remove old brake pads and install new ones, ensuring they are oriented correctly.
For rotors, remove the retaining screws (if applicable) and pull the rotor off. Replace with a new rotor, tightening to the specified torque value (refer to vehicle manual for exact specs).
Reinstall the caliper and tighten bolts to the specified torque value.

4. Reassemble and Test

Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Reconnect the negative battery terminal.
Pump the brake pedal a few times to restore brake pressure before driving.
