Solution

1. Preparation

Gather tools and parts required for the brake replacement.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel

Tools Required: Socket set, torque wrench
Loosen lug nuts slightly before lifting the vehicle.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Remove Brake Caliper

Tools Required: Socket set, brake caliper tool
Locate the caliper bolts and remove them using the socket.
Carefully slide the caliper off the rotor. Support it with a wire or bungee cord to avoid hanging on the brake line.
Remove the old brake pads from the caliper bracket.

4. Inspect and Replace Components

Inspect the rotor for any damage; replace if necessary.
Install new brake pads into the caliper bracket.
If rotors are being replaced, remove old rotors and install new ones according to the manufacturer's specifications.

5. Reinstall Brake Caliper

Slide the caliper back over the new pads and rotor.
Reinstall caliper bolts and torque them to manufacturer specifications.

6. Reassemble Wheel

Place the wheel back onto the hub and hand-tighten lug nuts.
Lower the vehicle and then torque lug nuts to the specified torque value.
Reconnect the negative battery terminal.

7. Final Checks

Pump the brake pedal several times to seat the new pads.
Check brake fluid level and top off if necessary.
