Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during the repair.

2. Remove the Wheel

Use a socket set to loosen the lug nuts while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Sub-step 1: Remove the caliper bolts using a socket wrench and slide the caliper off the rotor.
Sub-step 2: Take out the old brake pads from the caliper bracket.
Sub-step 3: Inspect the caliper and bracket for wear and clean as necessary.
Sub-step 4: Install new brake pads, ensuring they are oriented correctly.
Sub-step 5: Apply brake grease to the backing of the pads to reduce noise.

4. Inspect and Replace Brake Rotors (if needed)

Sub-step 1: Check the rotor thickness using a micrometer; if below specifications, replace the rotor.
Sub-step 2: Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Sub-step 3: Install the new rotor, ensuring it is seated properly.
Sub-step 4: Torque the retaining screws to the manufacturer’s specifications.

5. Reassemble and Test

Reattach the caliper over the new pads and tighten the caliper bolts to the specified torque settings.
Reinstall the wheel and tighten the lug nuts in a star pattern.
Lower the vehicle and reconnect the battery.
