Brake Fluid Change - 2016 Hyundai Sonata.

Changing the brake fluid on your 2016 Hyundai Sonata is a key maintenance task that ensures the longevity and effectiveness of your braking system. Over time, brake fluid can absorb moisture, leading to a decrease in braking performance and potential damage to the system's components. Let’s walk through the steps of performing this task, and I’ll include some key information such as tools needed, torque specs, and costs.

Tools and Supplies Required:

• DOT 3 or DOT 4 Brake Fluid (for the 2016 Hyundai Sonata)
• Wrench set (size 10mm for bleeder valves)
• Brake bleeder kit (optional but recommended)
• Jack and jack stands
• Tire iron or impact wrench for wheel removal
• Gloves and safety goggles
• Drip pan
• Clean rags or towels
• Turkey baster (optional for fluid removal from reservoir)

Cost Breakdown:

• Brake fluid: About $7–$15 for a quart (you’ll need approximately 1–2 quarts).
• Labor cost (if taken to a shop): Between $80–$120.

If you DIY, your total cost should be under $30.

Step-by-Step Guide:

1. PreparationStart by parking the car on a level surface. Turn off the engine and ensure the car is cool. Engage the parking brake. Then, use a jack to lift the car and secure it with jack stands.
2. Remove the WheelsUse a tire iron or impact wrench to remove the lug nuts and take off the wheels to access the brake calipers and bleeder valves.
3. Drain Old FluidOpen the brake fluid reservoir located under the hood and use a turkey baster to remove as much old fluid as possible. Be careful to avoid spilling brake fluid, as it is corrosive to paint.
4. Bleed the BrakesStarting from the wheel farthest from the brake master cylinder (usually the rear passenger side), loosen the bleeder valve using a 10mm wrench. Attach a bleeder kit or a clear tube to the valve, ensuring the other end leads into a container. Have a helper pump the brake pedal slowly while you open the valve, allowing the old fluid to drain. Close the valve before the pedal is released to prevent air from entering the system.
5. Add Fresh Brake FluidContinuously monitor the brake fluid level in the master cylinder and add fresh brake fluid as needed. Do not let the reservoir run dry during the bleeding process, as this will introduce air into the system.
6. Repeat for All WheelsRepeat the bleeding process for the remaining wheels (typically, the sequence is rear passenger, rear driver, front passenger, and front driver). Ensure each line has fresh fluid flowing through it before moving to the next wheel.
7. Final Check and ReassemblyOnce all wheels have been bled, check the brake fluid level and top it off if necessary. Reinstall the wheels and lower the car off the jack stands. Tighten the lug nuts to the manufacturer’s specifications (usually 80-100 lb-ft for most cars, but verify your Sonata's specific torque requirements).
8. Test DriveAfter completing the brake fluid change, perform a short test drive to ensure the brakes are functioning properly. You should feel a firm brake pedal and smooth braking performance. If the pedal feels spongy or soft, there may still be air in the system, and re-bleeding will be necessary.

FAQs

1. How often should brake fluid be changed in a 2016 Hyundai Sonata?It’s recommended to change the brake fluid every 30,000 miles or every 2 years, depending on your driving conditions.

2. Can I use DOT 3 brake fluid instead of DOT 4?Yes, Hyundai recommends either DOT 3 or DOT 4 brake fluid for the 2016 Sonata, but DOT 4 has a higher boiling point and is often preferred in hotter climates or for more demanding driving.

3. What are the signs that my brake fluid needs to be changed?A spongy or soft brake pedal, longer braking distances, and a dark or dirty fluid appearance are indicators that your brake fluid should be replaced.

4. How much brake fluid is required for a complete fluid change?Typically, 1-2 quarts are enough for a full brake fluid replacement, but it’s always good to have extra on hand.

Performing a brake fluid change on your 2016 Hyundai Sonata is a cost-effective and straightforward way to ensure your braking system is functioning optimally. By doing it yourself, you’ll save both time and money while enhancing the overall safety of your vehicle.
