Pads and rotors - yes. Fluid - probably not. Usually changing fluid every 2 years is a good idea. Both to keep brakes performance and prevent rusting due to water slowly making it’s way into the system.
- coryrc 3y agoI've never changed every two years on any vehicle.
- fragmede 3y agoThat's a useless data point without knowing how much you drive. a taxicab or police vehicle racks up hundreds of thousands of miles per year, and thus needs fluids far more often than every two years.
- mantas 3y agoDriving style, mileage and climate. Nice and dry climate is one thing, wet snowy & slushy roads for months every year is another thing.
- cyberax 3y agoTesla recommends checking the fluid level once every 4 years. Brakes on Teslas normally are not used much, so the fluid doesn't get heated.
- tristor 3y agoBrake fluid is not flushed due to heat cycling, that is what bleed maintenance is for. Flushing every 2 years is because brake fluid is hygroscopic (absorbs water), and even brake systems are not perfectly sealed. Water in the fluid reduces its effectiveness and can cause rusting in the brake lines, leading to failure. EVERY vehicle should have brake fluid flushed every 2 years. That Tesla recommends 4 years is straight out incompetent.
- fragmede 3y agoOn a system as critical as the brakes, I highly doubt they yolo just guessed and said, eh, just make it 4 years, that sounds good. I find it far more believable they did extensive testing of the brake system, which they build, and thus know just how much water is and isn't getting into the system, and what a good fluid replacement interval is. Or maybe everyone that works there is an incompetent monkey and they never test anything, ever. It's probably that, definitely. That's also why we see so many stories in the news about 5 year old Tesla's brakes failing. Given that we all know how long full self driving has been promised, I'm sure we'll get those news stories any day now.
- tristor 3y agoLike anything in safety critical engineering there are margins of safety. Seal failures in the top end of the brake system can cause water ingress without immediate impact on the braking system but will eventually cause hard lines to rust through, causing sudden and catastrophic failure of the braking system. The hydraulic portion of the braking system in a Tesla is not significantly different than any other passenger car, so yes, it’s utterly incompetent to recommend twice the maintenance interval.
- mantas 3y agoMaybe Tesla is just hyper-focused on Silicon Valley? I could see brakes fluid lasting that long in such a nice climate. In Northern Europe where lower part of the car is in salty water bath for 6 months a year… Checking brake fluid LEVEL every 4 years feels like looking for a trouble.
- m463 3y agoMy manual says: Fluid Replacement Intervals Do not change or top up the Battery coolant or brake fluid. Tesla service technicians replace fluids at the regularly scheduled service intervals: • Brake Fluid. Every 2 years or 25,000 miles (40,000 km), whichever comes first. • Battery coolant. Every 8 years or 100,000 miles (160,000 km), whichever comes first.
