Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Secure the vehicle with wheel chocks.

2. Remove Wheel Assembly

Use a jack to lift the vehicle and support it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspect Rotors: Measure rotor thickness and check for warping.
Replace Rotors (if warped):
1. Remove the brake caliper using a socket set and hang it safely.
2. Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
3. Install the new rotor, ensuring it is properly seated.
4. Reattach the brake caliper and torque to factory specifications.

4. Inspect and Replace Brake Pads

Inspect Brake Pads: Check for uneven wear or thinning.
Replace Pads (if worn):
1. Remove the caliper bracket if necessary.
2. Slide out the old brake pads and replace them with new ones.
3. Use brake grease on the backing of the pads to reduce noise.
4. Reassemble the caliper bracket and caliper.

5. Wheel Alignment and Balance

After reassembling the brake components, take the vehicle to a professional for wheel alignment and balancing to ensure proper handling.
