Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, socket set, torque wrench, brake cleaner, and safety goggles.
Lift the vehicle with a jack and secure it on jack stands.
Remove the wheel to access the brakes.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and suspend it using a bungee cord (do not let it hang on the brake line).
3. Remove the old brake pads. Note their orientation for installation of new pads.
4. Inspect the caliper for signs of sticking; if it is stuck, proceed to clean or replace as necessary.
5. Install new brake pads, ensuring they are seated properly.
6. Reinstall the caliper and torque the bolts to manufacturer specifications (typically 20-25 ft-lbs).

3. Inspect and Replace Brake Rotors (if needed)

Sub-steps:
1. If rotors are warped, remove them by unscrewing the rotor retaining screws.
2. Clean the hub surface with brake cleaner.
3. Install new rotors, ensuring they are free from oil and debris.
4. Torque rotor retaining screws as specified.

4. Check and Replace Calipers (if needed)

Sub-steps:
1. If calipers are sticking, replace them by removing the brake line and caliper mounting bolts.
2. Install new calipers and bleed the brake system to remove any air.
3. Torque caliper mounting bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Pump the brake pedal to seat the new pads.
Test the brakes in a safe area to ensure proper function.
