Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, caliper gauge, brake cleaner, shop towels
Sub-steps:
1. Park the vehicle on a flat surface and turn off the ignition.
2. Engage the parking brake and place wheel chocks behind the rear tires.
3. Loosen the lug nuts slightly before lifting the vehicle.

2. Lift Vehicle

Sub-steps:
1. Use a jack to lift the front of the vehicle and secure it with jack stands.
2. Remove the front wheels using the lug wrench.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Locate the brake caliper and remove the bolts using a socket set.
2. Carefully slide the caliper off the rotor and support it without straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Measure the thickness of the old pads. If they are below 3mm, replace them.
5. Install new brake pads into the caliper bracket.
6. Compress the caliper piston using a caliper tool to fit over the new pads.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for grooves or uneven wear. If damaged, proceed to replace.
2. Remove the rotor by taking off the retaining screws and sliding it off the hub.
3. Clean the new rotor with brake cleaner to remove any protective oil.
4. Install the new rotor onto the hub and secure it with retaining screws.

5. Reassemble Brakes

Sub-steps:
1. Reposition the caliper over the new brake pads and align it with the bracket.
2. Tighten the caliper bolts to the manufacturer's specified torque (usually around 25-30 ft-lbs).
3. Repeat the process on the opposite side if needed.

6. Reinstall Wheels

Sub-steps:
1. Place the wheels back on and hand-tighten the lug nuts.
2. Lower the vehicle using the jack and remove jack stands.
3. Tighten the lug nuts in a crisscross pattern to the specified torque (usually around 76 ft-lbs).

7. Final Check

Sub-steps:
1. Pump the brake pedal several times to seat the pads against the rotors.
2. Check brake fluid level and top off if necessary.
