Solution

1. Preparation

Gather all tools and parts required.
Ensure the vehicle is on a level surface and secure with wheel chocks.
Disconnect the battery to prevent electrical issues.

Tools Required:

Floor jack and jack stands
Lug wrench
Torque wrench
Brake caliper tool
Micrometer

2. Remove Wheel

Loosen lug nuts slightly before lifting the vehicle.
Use the floor jack to elevate the vehicle and secure it with jack stands.
Fully remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect: Check for signs of uneven wear on brake pads and rotors.
Replace: If wear is uneven, remove the caliper bolts using the appropriate socket. Carefully slide the caliper off the rotor and support it to avoid strain on the brake line.
Remove the old brake pads by sliding them out from the caliper bracket.
Insert new brake pads ensuring they are oriented correctly and are compatible with the caliper.

4. Inspect and Repair Caliper

Inspect Caliper: Check for sticking pistons or damaged seals.
Repair/Replace: If the caliper is malfunctioning, rebuild it or replace it with a new unit as necessary. Ensure it moves freely.

5. Check and Adjust Suspension

Inspect suspension components such as control arms and bushings for wear.
If necessary, adjust or replace components to ensure proper alignment.

6. Reassemble and Test

Reattach the caliper and torque the caliper bolts to the manufacturer's specifications.
Reinstall the wheel and torque the lug nuts to the specified value.
Reconnect the battery.
