Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid electrical issues during the repair.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel: Use a socket set to remove the lug nuts and take off the wheel.
2. Remove brake caliper: Use a socket wrench to remove the caliper mounting bolts. Suspend the caliper using a bungee cord to avoid stressing the brake line.
3. Remove brake rotor: If necessary, remove the rotor retaining screws and slide the rotor off the hub.
4. Inspect the rotor: Check for cracks, warping, or uneven surfaces.
5. Replace the rotor: If damaged, install a new rotor and torque the retaining screws to the manufacturer specifications (typically about 9-11 Nm).

3. Inspect and Replace Brake Pads

Sub-steps:
1. Inspect brake pads: Check for thickness and even wear. Replace if they are worn down or uneven.
2. Install new brake pads: Apply brake grease on the backing of the pads, then slide them into the caliper bracket.
3. Reinstall the brake caliper: Position the caliper over the new pads and torque the caliper bolts to the specifications (usually around 25-30 Nm).

4. Wheel Alignment and Balancing

Sub-steps:
1. Check tire balance: Take the vehicle to a tire shop for professional balancing.
2. Perform wheel alignment: Ensure all suspension components are tight and have a qualified technician align the wheels to manufacturer specifications.
