Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brake pads are being replaced.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Use a socket set to remove the lug nuts from the wheel.
Take off the wheel and set it aside.

4. Remove the Brake Caliper

Locate the caliper mounting bolts and remove them using a socket wrench.
Carefully slide the caliper off the rotor and support it with a bungee cord or rope to avoid straining the brake line.

5. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Compare new pads to old pads to ensure correct size and fit.
Apply brake grease to the back of the new pads to reduce noise.
Install the new pads into the caliper bracket.

6. Reassemble the Brake Components

Compress the caliper piston using a C-clamp or brake caliper tool to fit over the new pads.
Reattach the caliper over the new pads and secure it with the mounting bolts, tightening them to the manufacturer’s specified torque.

7. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specified value.

8. Final Checks

Reconnect the battery.
Pump the brake pedal a few times to seat the new pads.
Check brake fluid level and top off if necessary.
