Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and securely raised on jack stands.
Disconnect the battery if electrical components will be accessed.

2. Remove Front Wheels

Use a lug wrench to loosen the wheel lug nuts.
Lift the front of the vehicle with a jack and secure it with jack stands.
Remove the lug nuts and take off the front wheels.

3. Inspect and Replace Brake Rotors

Inspect: Check the rotors for warping using a runout gauge. If warping exceeds specifications, proceed to replace.
Remove: Unbolt the caliper mounting bracket and carefully remove the caliper. Support it with a bungee cord—do not hang it by the brake line.
Remove the old rotor by unbolting from the hub.
Install: Place the new rotor onto the hub and secure it according to manufacturer specifications. Torque the bolts to the recommended value (usually around 60-80 ft-lbs).

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Install: Place new pads into the bracket, ensuring they are oriented correctly.
Compress the caliper piston using a brake caliper tool to allow new pads to fit over the rotor.

5. Reassemble Components

Reattach the caliper over the new brake pads and torque the caliper bolts to specification.
Reinstall the front wheels and torque the lug nuts in a crisscross pattern to the manufacturer's specification (typically around 90-110 ft-lbs).

6. Test Brakes

Reconnect the battery if it was disconnected.
Start the vehicle and pump the brake pedal to ensure proper engagement.
Test drive the vehicle at low speeds to verify the repair and ensure no vibrations occur.
