Solution

1. Preparation

Gather necessary tools and parts before starting.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Brake cleaner
Torque wrench
OBD-II scanner (if needed)
Screwdriver or brake tool (if necessary)

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is still on the ground.
Jack up 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

Remove the caliper bolts using the appropriate socket.
Carefully slide the caliper off the rotor and support it without disconnecting the brake line.
Inspect the brake pads for wear; replace if they are below the manufacturer's minimum thickness.
If replacing, remove the old pads and install new pads, ensuring they are properly aligned.

4. Inspect and Replace Brake Rotors

Check the rotor for signs of damage or excessive wear.
If replacing, remove the rotor by removing any retaining screws or clips.
Install the new rotor, ensuring it is seated correctly. Torque to manufacturer's specifications.

5. Reassemble Brakes

Reattach the brake caliper and torque the caliper bolts to the manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and fully tighten the lug nuts in a star pattern.

6. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal several times to ensure proper brake pad seating.
Test drive the vehicle at low speed to ensure proper braking function.
