Solution

1. Preparation

Gather tools: socket set, torque wrench, jack, jack stands, brake pad spreader, and a brake cleaner.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Disconnect the battery to prevent accidental electrical shorts.

2. Lift the Vehicle

Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Remove the Brake Caliper

Use the socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the brake rotor and support it using a bungee cord or rope to avoid stress on the brake line.

4. Replace the Brake Pads

Remove the old brake pads from the caliper bracket by sliding them out.
Clean the caliper bracket and inspect for wear or damage.
Insert the new brake pads into the caliper bracket, ensuring they are properly aligned.
Use the brake pad spreader to push back the caliper piston to accommodate the new pads.

5. Reinstall the Brake Caliper

Carefully position the caliper over the new brake pads.
Reinstall and torque the caliper mounting bolts to the manufacturer’s specifications (typically around 25-30 Nm).

6. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Reconnect the battery and pump the brake pedal a few times to ensure proper pad seating.
Test drive the vehicle to confirm proper brake function.
