Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues while working.

2. Remove Wheel

Loosen lug nuts using a socket set.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake caliper.

3. Remove Brake Caliper

Remove the caliper bolts using a socket wrench (typically 13mm or 15mm).
Carefully slide the caliper off the rotor. Support it with a bungee cord to avoid stress on the brake line.
If the caliper is stuck, gently tap it with a rubber mallet to free it.

4. Inspect and Replace Components

Check the condition of the brake pads and replace them if worn down.
Inspect the caliper piston for damage or corrosion; replace the caliper if necessary.
If fluid leakage is present, replace the caliper seal or the entire caliper assembly.

5. Reassemble

Reverse the disassembly steps: position the caliper back over the rotor and secure it with the caliper bolts. Torque the bolts to the manufacturer's specifications (typically 25-35 ft-lbs).
Reinstall the wheel and tighten the lug nuts to the specified torque (usually 75-100 ft-lbs).

6. Final Checks

Reconnect the battery.
Bleed the brake system if caliper replacement was performed to remove air from the brake lines.
Test the brake system for proper function before driving.
