Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and securely lift it with jack stands.
Disconnect the battery to ensure safety while working on the braking system.

2. Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake cleaner, rotor puller (if necessary).
Remove the wheel and tire.
Unbolt the caliper and suspend it without stressing the brake line.
Remove the old rotor by unbolting it from the hub assembly.
Clean the new rotor with brake cleaner to remove oil or residue before installation.
Install the new rotor onto the hub and torque bolts to the manufacturer's specifications (typically 80-100 ft-lbs).

3. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Apply brake grease to the backing of the new pads to prevent noise.
Install the new brake pads into the caliper bracket.
Reinstall the caliper over the new pads and tighten bolts to specifications (typically 20-30 ft-lbs).

4. Reassemble and Test

Reinstall the wheel and tire, tightening lug nuts to the specified torque (usually 100-150 ft-lbs).
Reconnect the battery and lower the vehicle.
Pump the brake pedal to seat the new pads before driving.
