Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Loosen the lug nuts slightly while the vehicle is on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake caliper.

3. Inspect Brake Caliper

Tools Required: Torque wrench, socket set.
Visually inspect the caliper for any signs of leaks or damage.
Check the condition of the brake pads and ensure they are evenly worn.
If the caliper is leaking, proceed to remove it for replacement.

4. Remove and Replace Caliper

Tools Required: Socket set, brake caliper tool, brake cleaner.
Remove the bolts securing the caliper to the bracket using a socket set.
Carefully slide the caliper off the brake rotor.
Disconnect the brake line from the caliper, using a wrench to avoid stripping the fitting.
Attach the new caliper and reconnect the brake line, ensuring it is tightened to manufacturer's specifications.
Reinstall the caliper onto the bracket and secure it with the bolts.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specification.
Reconnect the negative battery terminal.
Pump the brake pedal several times to ensure the caliper piston is seated.
