Solution

1. Preparation

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

2. Remove Wheel

Use a jack to lift the vehicle and securely place it on jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor and hang it with a bungee cord to avoid straining the brake line.
Remove the old brake pads. Check the backing plates for wear.
Install new brake pads, ensuring they are aligned correctly with the caliper.

4. Inspect and Replace Brake Rotors (if necessary)

Check for rotor thickness using a micrometer; if below specification, replace.
Remove rotor retaining screws (if applicable) and slide the rotor off the hub.
Clean the hub surface and install the new rotor, ensuring it is flush against the hub.

5. Reassemble Components

Reattach the caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer specifications (usually around 20-30 ft-lbs, check specific values for your model).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle from jack stands and remove the jack.
Reconnect the negative battery terminal.
Test the brakes by pressing the pedal several times to ensure proper seating of the pads.
