Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Loosen lug nuts on the wheel before lifting the vehicle.

2. Lift Vehicle and Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Raise the vehicle using the jack, then secure it with jack stands.
Remove the wheel to access the brake caliper.

3. Remove the Brake Caliper

Tools Required: Socket set
Unscrew the caliper mounting bolts and carefully slide the caliper off the brake rotor.
Support the caliper using a bungee cord or wire to avoid straining the brake line.

4. Inspect and Replace Components

Check the condition of the caliper piston and seals.
If the piston is corroded or the seals are damaged, replace the caliper.
Parts Required: New brake caliper (if needed), brake pads (if worn), brake fluid
Clean the mating surfaces of the caliper and rotor.

5. Reinstall the Caliper

Slide the new or serviced caliper back onto the rotor.
Torque the caliper mounting bolts to the manufacturer's specification (typically 25-30 ft-lbs).
Reattach the brake line to the caliper if it was removed.

6. Bleed the Brakes

Tools Required: Brake bleeder kit
Top off the brake fluid reservoir with the appropriate brake fluid.
Start bleeding the brakes from the farthest caliper to the closest, ensuring all air is removed from the brake lines.

7. Reassemble and Test

Put the wheel back on and torque the lug nuts to specification (typically 80-90 ft-lbs).
Lower the vehicle and perform a test drive to ensure proper brake function.
