Solution

1. Preparation

Gather tools and materials. Ensure the vehicle is parked on a level surface.
Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, torque wrench, new brake pads, new rotors (if necessary), brake fluid.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel using a lug wrench.

3. Remove Brake Components

Remove the caliper bolts using a socket set.
Carefully lift the caliper off the rotor and support it without stretching the brake line.
Remove the old brake pads from the caliper bracket.

4. Inspect and Replace Parts

Inspect the rotor for wear; if warped or damaged, replace it.
Clean the caliper bracket and rotor with brake cleaner.
Install new brake pads into the caliper bracket. Ensure they are positioned correctly.
If replacing rotors, remove the old rotor and install the new one, ensuring it is properly seated.

5. Reassemble Braking System

Reattach the caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer’s specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically around 75-80 ft-lbs).
Pump the brake pedal several times to ensure proper pad seating and brake fluid pressure.
