Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the wheel is still on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor; support it with a bungee cord or rope to avoid strain on brake lines.
Remove the old brake pads from the caliper bracket.
Inspect the brake pad backing for damage or wear indicators.
Clean the caliper bracket with brake cleaner, ensuring no debris remains.
Install new brake pads in the bracket, ensuring they are oriented correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Examine the rotors for grooves or warping; replace if necessary.
If replacing, remove the rotor by removing the retaining screws or caliper bracket if applicable.
Install new rotors, ensuring they are properly seated and secured.

5. Reassemble Components

Reattach the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque settings (usually around 25-35 ft-lbs).
Reinstall the wheel, hand-tighten the lug nuts, and lower the vehicle.
Once the vehicle is on the ground, torque the lug nuts to the specified value (typically 100-150 ft-lbs depending on the model).

6. Final Checks

Reconnect the battery.
Pump the brake pedal a few times to ensure proper seating of the brake pads.
Check brake fluid levels and top off if necessary.
