Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, C-clamp or brake caliper tool, brake cleaner, shop rags.
Lift the vehicle using the jack and secure it with jack stands.
Remove the wheel using a lug wrench.

2. Remove the Brake Caliper

Locate the brake caliper bolts and remove them using the socket set.
Carefully slide the caliper off the rotor. Support the caliper with a bungee cord or hang it to avoid stressing the brake line.

3. Remove Old Brake Pads

Slide the old brake pads out of the caliper bracket. Note the orientation for reinstallation.
Inspect the caliper brackets and clean them with brake cleaner and a shop rag.

4. Compress the Brake Caliper Piston

Use a C-clamp or brake caliper tool to compress the piston back into the caliper housing to make room for the new pads.
Ensure that the brake fluid reservoir cap is loosened to prevent pressure buildup.

5. Install New Brake Pads

Insert the new brake pads into the caliper bracket in the same orientation as the old ones.
Ensure they are seated properly against the rotor.

6. Reinstall the Brake Caliper

Slide the caliper back over the new brake pads and rotor.
Reinstall the caliper bolts and tighten to the manufacturer's specified torque (typically around 25-35 lb-ft).

7. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically around 100-120 lb-ft).
Pump the brake pedal a few times to ensure proper pad seating and brake pressure.
