Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Use wheel chocks to prevent rolling.

2. Remove Wheel

Use a lug wrench to loosen the wheel lug nuts.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Sub-step 1: Remove the caliper bolts using a socket set.
Sub-step 2: Carefully slide the caliper off the brake rotor.
Sub-step 3: Remove the old brake pads from the caliper bracket.
Sub-step 4: Inspect the caliper for any damage or fluid leaks.
Sub-step 5: Install new brake pads, ensuring they are properly aligned.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-step 1: Check rotor surface for grooves or warping using a straight edge.
Sub-step 2: If needed, remove the rotor by unscrewing the retaining screws.
Sub-step 3: Install new rotors and torque to manufacturer specifications (typically around 80-100 ft-lbs).

5. Reassemble Braking System

Sub-step 1: Reattach the caliper over the new brake pads.
Sub-step 2: Reinstall caliper bolts and torque them to manufacturer specifications.
Sub-step 3: Replace the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test Brakes

Remove jack stands and lower the vehicle.
Tighten the lug nuts in a star pattern to the specified torque.
Pump the brake pedal a few times to ensure proper engagement before test driving.
