Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical issues.

Tools Required:

Jack and jack stands
Lug wrench
Brake line wrench
Torque wrench
Screwdrivers
Clean rags

2. Remove the Wheel

Loosen the lug nuts on the wheel where the caliper is located.
Use the jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove the Caliper

Locate and remove the caliper mounting bolts using the socket set.
Carefully slide the caliper off the rotor. Do not let it hang by the brake line; use a bungee cord to hang it from the suspension.
Detach the brake line from the caliper using the brake line wrench. Have a container ready to catch any leaking brake fluid.

4. Inspect and Replace Seals

Inspect the caliper piston and seals for wear or damage. If seals are damaged, replace them.
If the caliper is severely corroded or damaged, consider replacing the entire caliper.
Clean the caliper surface and ensure no debris is present.

5. Reassemble

If seals were replaced, lubricate them with brake fluid before reassembly.
Reattach the brake line to the new or repaired caliper and tighten the fitting to the manufacturer's specifications.
Slide the caliper back onto the rotor and secure it with the mounting bolts. Use the torque wrench to tighten to the specified torque (usually around 20-30 ft-lbs, check specifications).

6. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and then use the torque wrench to tighten the lug nuts to the specified torque (typically 75-85 ft-lbs).

7. Test the Brake System

Reconnect the negative battery terminal.
Press the brake pedal several times to build brake pressure.
Check for any leaks around the caliper and brake line.
Test drive the vehicle at low speeds to ensure proper braking function.
