Step-by-Step Procedure

----------------------

### 1. Preparation (5 minutes)

* **Safety First**: Ensure the vehicle is on a flat surface, engage the parking brake, and place wheel chocks behind the wheels.

### 2. Lifting the Vehicle (5 minutes)

* **Jack Up the Car**: Use the jack to lift the vehicle and secure it on jack stands.

- **Image**: Showing the jack lifting the car and the car secured on jack stands.

### 3. Wheel Removal (2 minutes per wheel, 10 minutes total)

* **Remove Wheels**: Use a lug wrench to remove the wheel bolts and take off the wheels.

### 4. Accessing Brake Pads (10 minutes per side, 20 minutes total)

* **Front Brakes**: Turn the steering wheel to access the calipers easily. Remove the caliper bolts and slide the caliper off the rotor.

* **Rear Brakes**: For electronic parking brakes, use an OBD scanner to release the parking brake. Then, remove the caliper bolts.

### 5. Removing Old Brake Pads (10 minutes per side, 20 minutes total)

* **Old Pads**: Remove the old brake pads from the caliper bracket.

* **Sensor**: Remove the speed sensor if damaged

* **Check Components**: Inspect the caliper, rotor, and brake lines for wear or damage.

### 6. Installing New Brake Pads (15 minutes per side, 30 minutes total)

* **Clean and Lubricate**: Clean the caliper and caliper bracket with brake cleaner. Apply anti-seize lubricant to the contact points where the pads rest.

* **Compress Piston**: Use a brake pad spreader or C-clamp to compress the caliper piston fully.

* **Install Sensor**: Install the speed sensor if required

* **Install Pads**: Place the new brake pads into the caliper bracket.

* **Image**: Clean caliper bracket and piston being compressed.

### 7. Reassembling the Brakes (10 minutes per side, 20 minutes total)

- **Reattach Caliper**: Reinstall the caliper over the new brake pads and secure with caliper bolts.

- **Image**: Caliper being reattached with new brake pads in place.

### 8. Reattaching Wheels (3 minutes per wheel, 15 minutes total)

* **Install Wheels**: Reattach the wheels and tighten the lug nuts by hand. Lower the vehicle and use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.

- **Image**: Wheel being reattached and tightened with a torque wrench.

### 9. Final Checks (10 minutes)

* **Brake Fluid**: Check and top up brake fluid if necessary.

* **Test Brakes**: Pump the brake pedal until it feels firm. Test drive the vehicle at low speeds to ensure proper brake function.

- **Image**: Brake fluid level being checked and the car being test-driven.

* Computer resetting if required

### Safety and Quality Assurance

* Always use genuine or high-quality aftermarket parts.

* Adhere strictly to torque specifications to avoid damage.

* Double-check all bolts and components before concluding the job.

* Ensure proper disposal of old brake pads and any other waste materials.

### Total Time Required

**2 hours and 30 minutes**

By following this SOP, you ensure a safe, effective, and professional brake pad change for any vehicles.
