Solution

1. Preparation

Gather tools and parts needed for the brake replacement.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle depending on which brakes are being replaced.
Secure the vehicle with jack stands to ensure stability.

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts from the wheel.
Take off the wheel to access the brake components.

4. Remove Brake Caliper

Using a socket set, remove the bolts securing the brake caliper to the caliper bracket.
Carefully slide the caliper off the brake rotor. Avoid stressing the brake line; support the caliper with a bungee cord or rope.

5. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Compare the thickness of the old pads with new pads to confirm replacement.
Install new brake pads into the caliper bracket.

6. Inspect and Replace Rotor (if needed)

If the rotors are worn or damaged, remove the rotor by unscrewing any retaining screws and sliding it off the wheel hub.
Install a new rotor and torque any retaining screws to manufacturer specifications.

7. Reassemble Components

Slide the caliper back over the new brake pads.
Reinstall the caliper bolts and torque them to manufacturer specifications.

8. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and tighten the lug nuts to the appropriate torque specification.

9. Test Brakes

Pump the brake pedal several times to seat the pads before driving.
Check for any leakage around the caliper and ensure proper function of the brakes.
