Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Use a jack and jack stands to lift the vehicle safely.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Torque wrench
Brake cleaner
Torque specifications chart

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and suspend it with a bungee cord to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper for any damage and replace if necessary.
Install new brake pads, ensuring they are properly seated.
Compress the caliper pistons using a brake caliper tool to allow space for the new pads.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or below the minimum thickness, remove them by unscrewing the retaining screws (if equipped) and pulling the rotor off.
Clean the hub surface with brake cleaner.
Install new rotors, ensuring they are aligned properly.

5. Reassemble and Torque

Reattach the caliper over the new brake pads.
Tighten the caliper bolts to the manufacturer's specified torque (typically around 25-35 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Finalize

Lower the vehicle back to the ground and torque the lug nuts to the specified torque (typically around 100-120 Nm).
Pump the brake pedal a few times to seat the pads against the rotors.
