Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, lug wrench, brake cleaner, and safety glasses.
Safety Warnings: Ensure the vehicle is on a level surface; engage the parking brake before lifting the vehicle.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Use a lug wrench to remove the wheel nuts.
Take off the wheel and inspect the brake assembly.

4. Inspect and Replace Brake Pads

Sub-steps:
1. Check brake pad thickness; if below the manufacturer’s specification, replace the pads.
2. Remove caliper bolts using a socket set.
3. Slide the caliper off the rotor and support it to avoid straining the brake line.
4. Remove the old brake pads from the caliper bracket.
5. Install new brake pads, ensuring they are aligned properly with the caliper bracket.

5. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for scoring or warping; replace if damaged.
2. Remove rotor retaining screws (if applicable) and slide the rotor off the hub.
3. Clean the hub surface with brake cleaner to ensure proper contact with the new rotor.
4. Install the new rotor and secure it with retaining screws.

6. Reassemble Braking System

Reattach the caliper over the new brake pads.
Tighten caliper bolts to manufacturer specifications (typically 25-35 ft-lbs).
Reinstall the wheel and tighten lug nuts in a star pattern to the specified torque (typically 90-100 ft-lbs).

7. Lower Vehicle and Test

Remove jack stands and lower the vehicle.
Pump the brake pedal to seat the brake pads before test driving.
