Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for added safety.

2. Remove Wheel

Use a jack to lift the vehicle and support it on jack stands.
Remove the wheel lug nuts with a socket and ratchet.
Take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper bolts using a socket.
Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and inspect for any corrosion.
Install new brake pads into the caliper bracket ensuring they are seated properly.

4. Inspect and Replace Rotors (if necessary)

Check the thickness of the rotors with a micrometer; if below the manufacturer's specification, they need replacement.
Remove the caliper bracket bolts and take off the caliper bracket.
Remove the old rotor from the hub (if it is stuck, tap gently with a hammer).
Install the new rotor onto the hub, ensuring it sits flush.

5. Reassemble Components

Reattach the caliper bracket and torque the bolts to the manufacturer’s specifications (usually around 25-30 ft-lbs).
Slide the caliper back over the new brake pads and secure it with the caliper bolts.
Reinstall the wheel and torque lug nuts to the specified torque (typically 80-100 ft-lbs).

6. Final Checks

Pump the brake pedal several times to seat the pads against the rotors.
Reconnect the battery and check brake fluid levels, topping off if necessary.
