Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspection: Check the thickness of the brake pads. If they are below the manufacturer's minimum thickness, replacement is necessary.
Replacement:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the brake pads and hang it securely (do not let it dangle from the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads in the caliper bracket, ensuring proper orientation.
5. Compress the caliper piston using a brake caliper tool to allow space for the new pads.
6. Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer's specifications.

4. Inspect and Replace Brake Rotors (if necessary)

Inspection: Check rotors for any severe scoring or warping. If they exceed the thickness specifications or are damaged, replace them.
Replacement:
1. Remove the caliper bracket if it was not already removed.
2. Remove the rotor retaining screws, if equipped, and slide the rotor off the hub.
3. Install the new rotor, ensuring it sits flush against the hub.
4. Reattach the caliper bracket and torque to specifications.

5. Reassemble and Recheck

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
Reconnect the battery and test the brake system by pressing the pedal several times to ensure proper function.
