Solution

1. Preparation

Gather necessary tools and parts.
Park vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure with jack stands to ensure safety while working.

3. Remove the Wheel

Using a socket set, remove the lug nuts and take off the wheel.
Inspect the brake assembly visually before proceeding.

4. Inspect and Replace Brake Rotors

Inspection: Check rotors for warping using a dial indicator; if warped beyond specification, replacement is necessary.
Removal: Remove caliper bolts with a socket, then slide the caliper off the rotor. Support the caliper with a bungee cord to avoid straining the brake line.
Replace: Remove the rotor by unscrewing the retaining screws, if applicable. Install new rotor, ensuring it is clean and free of grease.

5. Inspect and Replace Brake Pads

Inspection: Check thickness; if worn below manufacturer specifications, replace.
Removal: Remove the caliper bracket bolts and slide off the bracket. Replace pads by sliding them out of the caliper bracket.
Installation: Apply brake grease to the back of the new pads, install them into the bracket, and reassemble the caliper.

6. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands using the hydraulic jack.
Torque the lug nuts to the manufacturer's specification (typically 80-100 ft-lbs).
