Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted using jack stands.
Wear safety glasses and gloves.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts from the wheel.
Remove the wheel to access the brake caliper.

3. Remove Caliper

Use a socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the brake rotor.
If needed, support the caliper using a bungee cord or wire to prevent stress on the brake line.

4. Inspect and Replace Components

Inspect the caliper for signs of damage or corrosion.
If the caliper is leaking, replace it with a new one.
Replace the brake pads if they show uneven wear or are worn down.
Check the caliper piston for smooth operation; replace if it does not move freely.

5. Reinstallation

Reinstall the caliper over the brake rotor and align it with the mounting bracket.
Tighten the caliper mounting bolts to the manufacturer’s specified torque (usually around 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Bleed the Brakes

Using a brake bleeder kit, bleed the brake lines to remove any air.
Start from the farthest wheel from the master cylinder and work towards the nearest.
