Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Use wheel chocks to prevent vehicle movement.

Tools Required:

Jack and jack stands
Lug wrench
Brake cleaner
Torque wrench
Socket set
Caliper tool (if replacing pads)
Multimeter (for electrical checks)

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle with the jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Visually inspect the brake pads, calipers, and rotors for uneven wear or damage.
Check the caliper slides for proper movement; clean and lubricate if necessary.
Measure rotor thickness and check for warping using a dial indicator.

4. Replace Brake Pads (if necessary)

Remove the caliper by unscrewing the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and support it with a bungee cord or hang it securely.
Remove the old brake pads from the caliper bracket.
Insert new brake pads into the caliper bracket, ensuring they are seated properly.
Use a caliper tool to compress the caliper piston if required for clearance.

5. Reassemble and Install Wheel

Reattach the caliper over the new brake pads and secure it with the caliper bolts; torque to manufacturer specifications.
Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and tighten the lug nuts to the specified torque.

6. Test

Pump the brake pedal to ensure proper pad seating and caliper function.
Check for any leaks around the caliper and lines.
