Solution

1. Preparation

Tools Required: Socket set, wrench set, C-clamp, brake cleaner, torque wrench, new brake caliper, brake fluid.
Safety Warnings: Disconnect the battery before working on electrical systems. Ensure the vehicle is on a stable surface and secured with jack stands.

2. Remove the Wheel

Loosen the lug nuts on the affected wheel using a lug wrench.
Lift the vehicle using a jack and securely place it on jack stands.
Completely remove the lug nuts and take off the wheel.

3. Remove the Brake Caliper

Locate the caliper mounting bolts and remove them using a socket or wrench.
Carefully slide the caliper off the rotor. If it's stuck, use a rubber mallet to gently tap it free.
Support the caliper with a bungee cord or a piece of wire to avoid straining the brake line.

4. Inspect and Replace Components

If the caliper is seized, it is advisable to replace it. Inspect the brake pads and rotor for wear; replace if necessary.
Clean the caliper mounting bracket and rotor with brake cleaner to ensure a good fit for the new caliper.

5. Install New Brake Caliper

Position the new brake caliper over the rotor and align it with the mounting bracket.
Install and tighten the caliper mounting bolts to the manufacturer’s torque specifications (typically around 25-35 Nm).
Reconnect the brake line to the new caliper, ensuring it is secure and leak-free.

6. Reinstall Wheel and Final Checks

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque (usually around 100-120 Nm).
Refill the brake fluid reservoir if necessary and bleed the brakes to remove air from the system.
