Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Lift the vehicle using a jack and support it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen lug nuts while the vehicle is on the ground.
Lift the vehicle and remove the lug nuts completely.
Take off the wheel to access the brake components.

3. Inspect Brake Components

Examine the brake pads and rotors for wear; replace if significantly worn.
Check the calipers for proper movement; clean and lubricate caliper slides if necessary.
Assess brake lines for leaks or damage.

4. Replace Brake Pads (if necessary)

Remove the caliper by unscrewing the caliper bolts using a socket set.
Slide the caliper off and support it without stressing the brake line.
Remove the old brake pads from the caliper bracket.
Compress the caliper piston using a C-clamp to allow space for new pads.
Install new brake pads in the caliper bracket.

5. Reassemble and Test

Reposition the caliper over the new pads and tighten the caliper bolts to manufacturer specifications (typically 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value (usually 80-100 ft-lbs).
Test the brakes by pressing the pedal a few times before driving.
