Solution

1. Preparation

Gather tools: socket set, torque wrench, brake cleaner, and safety glasses.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Lift the vehicle using a jack and secure it with jack stands.

2. Remove Wheel

Use the socket set to loosen and remove the lug nuts.
Carefully take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Sub-step 1: Visually inspect the brake pads for thickness. If they are below 3mm, replacement is necessary.
Sub-step 2: Remove the caliper bolts using the socket set.
Sub-step 3: Carefully slide the caliper off the brake pads without damaging brake lines.
Sub-step 4: Remove the old brake pads from the bracket.
Sub-step 5: Clean the caliper and bracket with brake cleaner to remove dust and debris.
Sub-step 6: Install new brake pads, ensuring they are aligned properly.
Sub-step 7: Reattach the caliper and torque the bolts to the manufacturer’s specifications (typically around 25-35 Nm).

4. Inspect and Replace Brake Rotors (if necessary)

Sub-step 1: Check the rotors for any scoring or warping.
Sub-step 2: If replacement is needed, remove the rotor by unscrewing the retaining screws (if equipped).
Sub-step 3: Install the new rotor in the reverse order of removal.
Sub-step 4: Clean the rotor surface with brake cleaner before installation.

5. Reassemble and Test

Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (typically 100-120 Nm).
Lower the vehicle and test the brakes by applying pressure to ensure proper function.
