Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a stable surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during the replacement.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Lift the vehicle using the jack and secure with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Remove Brake Caliper

Tools Required: Socket set, torque wrench
Sub-steps:
1. Locate the caliper mounting bolts and remove them.
2. Carefully slide the caliper off the rotor without stretching the brake line.
3. Support the caliper using a bungee cord or similar device to avoid stress on the brake line.

4. Replace Brake Pads

Tools Required: Piston tool (or C-clamp)
Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Use a piston tool or C-clamp to compress the caliper piston back into the caliper housing.
3. Install new brake pads into the caliper bracket, ensuring they are securely positioned.

5. Reassemble Components

Sub-steps:
1. Reattach the brake caliper over the new pads and secure it with the mounting bolts, tightening them to the manufacturer's torque specifications.
2. Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Sub-steps:
1. Lower the vehicle to the ground and fully tighten the lug nuts in a crisscross pattern.
2. Reconnect the battery and check the brake fluid level, topping off if necessary.
3. Pump the brake pedal a few times to ensure proper engagement.
