Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely parked.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts slightly while the vehicle is still on the ground.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.
Tools Required: Jack, jack stands, lug wrench

3. Inspect Brake Components

Sub-steps:
1. Visually inspect the brake pads; they should have a minimum thickness of 3mm.
2. Check rotors for grooves or scoring; they should be smooth and free of cracks.
3. Inspect calipers for proper function and any signs of sticking.
Tools Required: Flashlight, feeler gauge (if necessary)

4. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
1. Remove the caliper by unscrewing the caliper bolts using a socket.
2. Carefully slide the caliper off the rotor and secure it with a bungee cord to avoid straining the brake line.
3. Remove the old brake pads. If replacing rotors, unscrew the rotor retaining screws and slide off the rotor.
4. Install new rotors (if applicable), ensuring they are torqued to factory specifications.
5. Install new brake pads, making sure they are seated properly.
6. Reattach the caliper and torque the bolts to manufacturer specifications.
Tools Required: Socket set, torque wrench, bungee cord, brake cleaner

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from jack stands and then fully tighten the lug nuts in a crisscross pattern.
3. Reconnect the negative battery terminal.
4. Pump the brake pedal several times to ensure proper brake function.
Safety Warnings: Ensure vehicle is securely elevated and stable while working.
