Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to prevent movement during repairs.

2. Remove Front Wheels

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Lift the vehicle using the jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the front wheels.

3. Inspect and Replace Brake Components

Tools Required: Socket set, torque wrench, brake cleaner, and replacement parts (rotors and pads).
Sub-steps:
1. Remove the caliper by unbolting it from the bracket and hanging it with a bungee cord (do not let it dangle by the brake line).
2. Inspect the brake pads for wear and replace them if they are below the manufacturer’s specifications.
3. Remove the brake rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
4. Clean the hub surface with brake cleaner to prevent rotor distortion.
5. Install the new rotor and secure it with retaining screws.
6. Reinstall the caliper over the new pads and torque bolts to manufacturer specifications.

4. Wheel Alignment and Balancing

Tools Required: Alignment tools and balancing machine (if doing at home, visit a shop).
Sub-steps:
1. Check wheel alignment using an alignment machine.
2. Adjust camber, caster, or toe settings as needed according to specifications.
3. Balance the wheels using a balancing machine to ensure even weight distribution.

5. Reassemble and Test

Sub-steps:
1. Reinstall the front wheels and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
3. Perform a test drive to verify that the vibrations during braking have been resolved.
