Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.
Engage the parking brake for safety.

2. Raise the Vehicle

Loosen the lug nuts on the wheel of the affected brake.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel using the lug wrench.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using the socket set.
Carefully slide the caliper off the rotor and support it (do not hang it by the brake line).
Remove the old brake pads from the caliper bracket.
- Tools Required: Piston tool or C-clamp to compress caliper piston if replacing pads.
Inspect the condition of the new pads and ensure they are suitable for your model.
Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or warping.
If replacement is needed, remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install the new rotor, ensuring it’s properly seated against the hub.
- Torque Specification: Refer to specific torque values for rotor mounting screws in the service manual.

5. Reassemble the Brake Components

Reinstall the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque.
Reattach the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle

Carefully lower the vehicle back to the ground using the jack.
Tighten the lug nuts in a crisscross pattern to the specified torque.

7. Test the Brakes

Before driving, pump the brake pedal a few times to ensure proper pad seating.
Check the brake fluid level and add if necessary.
