Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery for safety.

2. Remove the Wheel

Use a jack to lift the vehicle and securely place it on jack stands.
Remove the wheel lug nuts with a socket wrench.
Take off the wheel to access the brake components.

3. Remove the Brake Caliper

Use a socket wrench to remove the caliper mounting bolts.
Carefully slide the caliper off the brake rotor.
Support the caliper using a bungee cord or a rope to avoid stress on the brake line.

4. Inspect and Clean the Caliper

Check the caliper piston for corrosion or dirt buildup.
Use brake cleaner to clean the caliper, piston, and slides.
Inspect the caliper slides and boots for wear or damage; replace if necessary.

5. Lubricate the Caliper Slides

Apply a high-temperature brake grease to the caliper slide pins and bushings.
Ensure that the grease is evenly distributed without over-applying.

6. Reassemble the Brake Components

Slide the caliper back onto the rotor and align it with the mounting bracket.
Reinstall the caliper mounting bolts and tighten to the manufacturer’s specified torque (usually around 25-30 Nm).
Reattach the wheel and hand-tighten the lug nuts.

7. Final Checks

Lower the vehicle and remove the jack stands.
Reconnect the battery.
Pump the brake pedal a few times to seat the caliper properly.
