Solution

1. Preparation

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

2. Remove Wheel

Using a jack, lift the vehicle and secure it with jack stands.
Remove the lug nuts using 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 secure it to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper for any signs of damage or sticking.
Install new brake pads, ensuring they are properly seated.

4. Inspect and Replace Rotors (if necessary)

Check the rotor surface for grooves or warping.
If replacement is needed, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install the new rotor and torque the screws to the manufacturer’s specification (typically around 70-90 ft-lbs, but check specific specs).

5. Reassemble Components

Reattach the caliper over the new pads and rotor.
Tighten the caliper bolts to the specified torque (usually 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and remove the jack stands.
Tighten the lug nuts to the specified torque (usually 80-100 ft-lbs).
Reconnect the battery terminal.
Pump the brake pedal a few times to ensure proper pad seating.
