Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, caliper tool, torque wrench.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the battery to avoid any electrical shorts.

2. Raise the Vehicle

Use the jack to lift the front or rear of the vehicle (depending on which brakes are affected).
Secure the vehicle with jack stands to prevent it from falling.
Remove the wheel using the lug wrench.

3. Inspect and Remove Brake Components

Inspect Brake Pads: Remove the caliper bolts and slide the caliper off the rotor. Check the pads for thickness; replace if less than 3mm.
Check Rotor Condition: Remove the rotor by unscrewing any retaining screws. Inspect for grooves or warping. Replace if needed.

4. Replace Brake Pads and Rotors

Install New Brake Pads: If necessary, compress the caliper piston using a caliper tool. Install new brake pads, ensuring they fit snugly and are properly aligned.
Fit New Rotors: If rotors were replaced, install them onto the hub, ensuring they are seated properly.

5. Reassemble Brake System

Reattach the caliper over the new pads and rotor, tightening the caliper bolts to the manufacturer's specified torque (usually around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

6. Final Checks

Reconnect the battery and check the brake fluid level, topping up if necessary.
Test the brake pedal for firmness before driving.
