Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Lift the vehicle using a jack and securely support it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a suitable socket.
Carefully slide the caliper off the rotor and suspend it using a bungee cord or similar to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper bracket for debris and clean if necessary.
Install new brake pads, ensuring they are properly aligned.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for deep grooves or warping.
If replacement is needed, remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
Install new rotors, ensuring they are clean and free of any oil or grease.

5. Reassemble Components

Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications (usually around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.
Once the vehicle is on the ground, torque the lug nuts to the manufacturer’s specifications (typically around 76-86 ft-lbs).

6. Final Checks

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