Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid accidental activation of the brake system.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Loosen the lug nuts on the affected wheel.
Lift the vehicle with the jack and secure it with jack stands.
Remove the lug nuts and the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, ratchet, brake pad spreader, torque wrench.
Remove the caliper bolts using the socket set.
Carefully slide the caliper off the rotor and support it without straining the brake line.
Inspect the caliper for proper movement and ensure it's not sticking.
Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and apply brake grease to the contact points.
Install the new brake pads, ensuring they are positioned correctly.
Reinstall the caliper over the new pads and secure it with the caliper bolts, torquing to manufacturer specifications.

4. Check and Replace Brake Rotor (if necessary)

If rotors are warped or worn, remove the rotor by unscrewing the retaining screws.
Replace with new rotors, ensuring they are properly aligned and secured.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
Reconnect the battery and pump the brake pedal to seat the pads.
