Solution

1. Preparation

Gather tools and safety equipment.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Brake cleaner
Brake pad spreader
OBD-II scanner (if checking brake warning codes)

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor; support it with a bungee cord to avoid stress on the brake line.
Remove the old brake pads from the caliper brackets.
Inspect the new brake pads for any manufacturing defects.
Install new brake pads, ensuring they are seated properly in the caliper bracket.

4. Inspect and Replace Brake Rotors (if needed)

Check the rotor surface for grooves or warping.
If rotors are damaged, remove the rotor by unscrewing the retaining screws (if present) and sliding it off the hub.
Install new rotors, ensuring they are clean from any protective oils.
Torque rotor retaining screws to manufacturer specifications (if applicable).

5. Reassemble Braking System

Reinstall the caliper over the new brake pads.
Tighten caliper bolts to manufacturer specifications.
Reattach the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and fully tighten the lug nuts in a crisscross pattern using a torque wrench.
Reconnect the battery.
