Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and eyewear.

2. Remove Wheel

Tools Required: Lug wrench, jack, jack stands.
Sub-steps:
1. Loosen the lug nuts while the vehicle is on the ground.
2. Lift the vehicle with a jack and securely place jack stands.
3. Remove the lug nuts and take off the wheel.

3. Inspect and Remove Caliper

Tools Required: Socket set, torque wrench, brake caliper tool.
Sub-steps:
1. Inspect the caliper for signs of damage or leaks.
2. Remove the caliper mounting bolts using the socket.
3. Carefully slide the caliper off the rotor and suspend it using a wire or bungee cord to avoid strain on the brake line.

4. Examine Components

Tools Required: Caliper tool, brake cleaner, rags.
Sub-steps:
1. Check the caliper piston for corrosion or binding.
2. Clean the caliper and surrounding area with brake cleaner.
3. Inspect the rubber seals and dust boots for cracks or wear.

5. Repair or Replace

Tools Required: Replacement caliper or repair kit, brake fluid.
Sub-steps:
1. If the caliper is damaged, install a new caliper following manufacturer specifications.
2. If repairing, replace seals and lubricate the piston before reinstallation.
3. Reattach the caliper to the bracket and torque the mounting bolts to the manufacturer’s specifications (typically around 25-35 ft-lbs).

6. Reassemble and Test

Tools Required: Lug wrench, brake fluid.
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and fully tighten the lug nuts in a star pattern to manufacturer specifications.
3. Pump the brake pedal to ensure proper caliper function.
4. Check and top off brake fluid as necessary.
