Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake rotor puller (if necessary).
Remove the wheel using the socket set.
Inspect the brake rotor for warping using a dial indicator or visual inspection.
If warped, remove the brake caliper (remove caliper bolts) and hang it using a bungee cord.
Remove the brake rotor (may require tapping with a hammer if stuck).
Install new or resurfaced rotors, ensuring they are torqued to the manufacturer’s specifications.

3. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Check the thickness of the brake pads; replace if below the minimum thickness.
Apply brake grease to the back of the new pads to reduce noise.
Install the new brake pads into the caliper bracket.

4. Reassemble and Test

Reinstall the brake caliper over the new pads and torque the caliper bolts.
Reattach the wheel and torque the lug nuts in a star pattern.
Reconnect the battery.
Pump the brake pedal to ensure the pads are seated properly before driving.
