Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to prevent movement.
Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, socket set.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Components

Brake Pads:
- Use a socket wrench to remove the caliper bolts.
- Carefully slide the caliper off the rotor and support it with a bungee cord or rope (do not let it hang on the brake line).
- Remove the old brake pads from the caliper bracket.
Brake Rotor:
- If replacing, remove the rotor by removing any retaining screws or tapping it gently with a hammer if it’s seized.

4. Inspect and Replace Components

Check the condition of the brake pads and rotors. Replace if worn beyond specifications (pads should be at least 1/4 inch thick; rotors should be smooth and within manufacturer specifications).
Clean the caliper bracket and rotor mounting surface with brake cleaner to remove any debris.
If applicable, replace brake hardware (shims, clips) to ensure proper fit and function.

5. Reassemble Brake Components

Install new brake pads into the caliper bracket.
If necessary, compress the caliper piston using a C-clamp to allow for the new pads.
Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications (typically around 25-30 ft-lbs).

6. Reinstall Wheel

Place the wheel back onto the hub.
Hand-tighten lug nuts, then lower the vehicle and torque the lug nuts to manufacturer specifications (usually 76-80 ft-lbs).
