Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to secure the vehicle.
Disconnect the battery (optional for safety).

2. Remove Wheel

Use a lug wrench to loosen the wheel lug nuts.
Lift the vehicle using a jack and secure it on jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-step 1: Remove the caliper by unscrewing the bolts using a socket set. Support it with a bungee cord or rope; do not let it hang by the brake line.
Sub-step 2: Remove the old brake pads from the caliper bracket. Note the orientation for reinstallation.
Sub-step 3: Clean the caliper bracket and rotor surface using brake cleaner to remove dust and debris.
Sub-step 4: Install new brake pads in the reverse order of removal, ensuring they are properly seated.

4. Lubricate Components

Sub-step 1: Apply brake grease to the back of the brake pads to reduce squeaking.
Sub-step 2: Lubricate the caliper slide pins and contact points with high-temperature brake grease.

5. Reassemble and Lower Vehicle

Reattach the caliper and tighten bolts to the manufacturer’s specified torque (usually around 25-30 Nm).
Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and fully tighten the lug nuts in a star pattern to ensure even pressure.
