Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, lug wrench, brake cleaner, torque wrench, and a C-clamp.
Raise the vehicle using a jack and secure it on jack stands.
Remove the wheels using the lug wrench.

2. Inspect and Replace Brake Pads

Remove Calipers:
- Locate the caliper mounting bolts and remove them with a socket wrench.
- Carefully lift the caliper off the rotor without damaging the brake line.
Remove Old Pads:
- Take out the old brake pads from the caliper bracket.
- Note the orientation of the pads for proper installation of new ones.
Compress Caliper Piston:
- Use a C-clamp to gently compress the caliper piston back into the caliper housing.
- Ensure the brake fluid reservoir cap is removed to allow fluid to return.
Install New Pads:
- Place new brake pads into the caliper bracket, ensuring correct orientation.
- Reattach the caliper over the new pads and secure with mounting bolts. Torque to manufacturer specifications (typically around 20-25 ft-lbs).

3. Inspect and Replace Calipers (if necessary)

Check Caliper Function:
- Manually push the caliper piston out and retract to ensure it moves freely.
Replace Caliper:
- Remove the brake line from the old caliper using a flare nut wrench.
- Install the new caliper, ensuring it is properly aligned and secured. Torque the mounting bolts to specifications.
- Reconnect the brake line and bleed the brakes to remove any air.

4. Final Checks

Reinstall the wheels and lower the vehicle.
Torque the wheel lug nuts to the specified value (typically around 80-100 ft-lbs).
