Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel Assembly

Tools Required: Jack, jack stands, lug wrench.
Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench, brake cleaner, new brake pads.
Remove the caliper bolts using a socket.
Carefully slide the caliper off the brake rotor.
Inspect the caliper slide pins for lubrication; replace or lubricate if necessary.
Remove the old brake pads and compare them with the new ones for wear.
Clean the caliper bracket with brake cleaner.
Install the new brake pads in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Rotor puller (if needed), torque wrench.
Check if the rotors are warped or corroded.
If replacement is needed, remove the rotor by taking off the retaining screws (if applicable).
Install the new rotor and torque it to the manufacturer specifications.

5. Reassemble Brake Assembly

Slide the caliper back onto the rotor and secure it with caliper bolts.
Tighten the caliper bolts to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle back to the ground.
Tighten the lug nuts in a crisscross pattern to the specified torque.
Reconnect the negative battery terminal.
Pump the brake pedal a few times to seat the brake pads.
