Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, C-clamp or brake caliper tool, socket set, torque wrench.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts of the wheel on the affected side.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake caliper.

3. Inspect and Remove Caliper

Sub-steps:
- Remove the caliper mounting bolts using a socket wrench.
- Carefully slide the caliper off the brake rotor.
- Support the caliper with a bungee cord or wire to avoid straining the brake line.
Safety Warning: Do not let the caliper hang by the brake line.

4. Repair or Replace Components

If the caliper is seized:
- Use a C-clamp to compress the caliper piston and attempt to free it. If unsuccessful, replace the caliper.
If the brake pads are unevenly worn:
- Replace the brake pads on both sides to maintain even braking.
Inspect the caliper for any visible damage or leaks, and replace if necessary.

5. Reassemble

Slide the caliper back over the brake rotor and reinstall the mounting bolts.
Torque the bolts to the manufacturer’s specifications (typically around 20-30 ft-lbs, but verify with specifications).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern.

6. Final Check

Press the brake pedal several times to ensure the caliper piston is seated properly.
Check the brake fluid level in the master cylinder and top off if necessary.
