Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Safety: Ensure the vehicle is in gear (manual) or in "Park" (automatic).

2. Remove Wheel

Use a socket set to loosen lug nuts slightly before lifting the car.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads

Check thickness: Measure the pad thickness; replace if below manufacturer specifications (usually 3mm or less).
Replace: Remove the caliper bolts using a socket set, slide the caliper off, and replace the pads.

Brake Rotors

Inspect for warping: Use a dial indicator to measure rotor runout; replace if warping exceeds manufacturer specifications (typically over 0.002 inches).
Resurface or Replace: If rotors are within specs but have surface imperfections, have them resurfaced. If too worn or damaged, replace with new rotors.

4. Reassemble Components

Reinstall the caliper over the new pads.
Torque caliper bolts to the manufacturer's specifications (typically 25-35 ft-lbs).
Reinstall the wheel and hand-tighten lug nuts.

5. Lower Vehicle and Finalize

Lower the vehicle off the jack stands and remove the jack.
Torque the lug nuts to the manufacturer's specifications (usually 80-100 ft-lbs).
Pump the brake pedal to ensure proper seating of the pads against the rotors.
