Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel

Tools Required: Lug wrench, jack, jack stands.
Loosen 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 completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench.
Remove the caliper bolts with the appropriate socket.
Carefully slide the caliper off the rotor and support it without straining the brake line.
Remove the old brake pads from the caliper bracket.
Inspect rotor condition; if warped or damaged, replace it.
Install new brake pads, ensuring they are seated properly in the caliper bracket.

4. Caliper and Brake System Check

Inspect the caliper for proper movement; clean and lubricate the caliper pins if sticking is observed.
Check for leaks in the brake lines and ensure the brake fluid level is adequate.
If calipers are faulty, replace them with new units.

5. Reassemble Components

Reattach the caliper over the new brake pads and torque the caliper bolts to the manufacturer specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually 100-120 ft-lbs).

6. Test Drive

Reconnect the negative battery terminal and pump the brake pedal a few times to seat the pads.
Conduct a test drive to ensure proper brake function and check for any abnormal noises or vibrations.
