Brake Fluid Flush for 2023 Lucid Air Touring - Recommended Interval?

Vehicle: 2023 Lucid Air Touring

Hi Lucid owners,

I own a 2023 Lucid Air Touring, and with EVs relying heavily on regenerative braking, I'm curious about the maintenance schedule for the traditional hydraulic brake system. Specifically, when should I consider a brake fluid flush?

My previous ICE cars had a clear interval, but I'm wondering if it's different for an EV due to less frequent use of the friction brakes. What are the recommendations from Lucid, or what have others experienced?

Thanks for the insights!

ClearTheCode admin answer:

That's an excellent question, Mike, and one that often comes up for EV owners. While regenerative braking significantly reduces wear on friction brake components, the hydraulic brake fluid still requires periodic maintenance.

Recommended Interval: Lucid, like most manufacturers, typically recommends a brake fluid flush every 2-3 years or 30,000-45,000 miles, whichever comes first. Always consult your specific 2023 Lucid Air Touring owner's manual for the precise recommended service interval, as it can vary slightly.

Why it's Important for EVs:

  1. Moisture Absorption: Brake fluid is hygroscopic, meaning it absorbs moisture from the air over time. This moisture lowers the fluid's boiling point, which can lead to brake fade under heavy use. While friction brakes are used less often in EVs, they still need to perform optimally in emergency situations.
  2. Corrosion: Water in the brake fluid can also cause corrosion within the brake lines, calipers, and ABS/stability control module, leading to expensive repairs down the line.
  3. System Integrity: The brake fluid is crucial for the proper functioning of your vehicle's ABS (Anti-lock Braking System) and electronic stability control systems. Old, contaminated fluid can compromise their performance.

Causes of Degradation: Time and exposure to ambient humidity are the primary culprits. Driving conditions, such as high humidity environments, can accelerate this process.

When to See a Shop:

  • Scheduled Maintenance: Adhere to Lucid's recommended service schedule.
  • Brake Warning Light: If your brake warning light illuminates on the dashboard, have the system inspected immediately.
  • Spongy Pedal: A soft or spongy brake pedal can indicate air or excessive moisture in the system, requiring a flush.
  • Fluid Contamination: If the brake fluid in the reservoir appears dark or murky, it's a sign it needs to be replaced.

Even with advanced regenerative braking, maintaining your hydraulic brake fluid is a critical safety and longevity aspect of your Lucid Air.
