Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the battery if working on electronic components.

2. Raise the Vehicle

Using a jack, lift the vehicle and secure it with jack stands.
Remove the wheels to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts with a socket set.
- Carefully slide the caliper off the rotor and hang it using a bungee cord to avoid straining the brake line.
- Remove the old brake pads and inspect for uneven wear.
Replace Brake Pads:
- Install new brake pads, ensuring they are oriented correctly.
- Use brake grease on the backing of the pads to reduce noise and improve movement.
- Reinstall the caliper over the new pads and tighten the caliper bolts to manufacturer specifications (typically around 25-35 Nm).

4. Check Caliper Functionality

Push the caliper piston back into the caliper housing using a C-clamp.
Ensure the caliper slides freely on its guide pins; lubricate if necessary.

5. Inspect Suspension and Alignment

Check for any worn or damaged suspension components, such as bushings or shocks.
If any components are damaged, replace them as necessary.
Align the wheels if misalignment is suspected.

6. Final Assembly

Reinstall the wheels and lower the vehicle.
Reconnect the battery if it was disconnected.
