EV cars brake fluid
Discussion
Not sure if the right part here.
But with the more EVs on the road, and the less "braking" due to motors or regen etc. Brake fluid is not getting used as much. So in theory more moisture built up.
And a service on a full EV is brake fluide n coolant and usual checks.
Has any manufactuar thought about a new fluid that is not hygroscopic. Its easy to add coolant but to do a brake fluid flush is a lot more involved.

Ev’s also rend to be heavier so more demanding on brakes.
We had an e power qashqai for the last month & the brakes front & rear are huge as I suppose they would need to be when repeatedly stopping 2 tons.
When a good chunk of the “braking” is done via regenerative braking?We had an e power qashqai for the last month & the brakes front & rear are huge as I suppose they would need to be when repeatedly stopping 2 tons.
Sorry
Looking back and reading 1st post i understand comments. And i am just asking question.
Maybe mentioning EVs changed the contex a bit.
It was just because going by stats they do less braking via pads n discs so to speak.
Does brake fluid on a car thats off road for 2 years have the same as one that being used 20k a year?

From what I gather in your post you seem to imply the heat generated under braking somehow evaporates any moisture contained in the fluid?
That's incorrect, thus the need to change fluid before the fluid becomes fully moisture absorbed and corrosion starts to occur in the system itself.

How many people do you think actually do that?
It's easy to check the fluid moisture level and I'd expect any decent mechanic to do it during a service, together with all the other usual checks. I have no comments about how many cars are serviced by people who aren't decent mechanics.Gassing Station | Suspension, Brakes & Tyres | Top of Page | What's New | My Stuff
