Electric vs petrol cars

[SexBomb]

Brake fluid is hygroscopic, needs to be replaced every 2 years. Cabin air filter same, ditto HEPA filter, A/C desiccant bag, etc just because they have an electric motor doesn't mean no maintenance.

Doesn't matter, brakes need servicing even if brake pads don't need replacing. FWIW the BYD is probably the worst EV for one pedal driving.

EV's are only quieter than ICEV's when accelerating and even then up to around 60 kph, much over that the tyre, road and wind noise drowns out the ICE anyway. Try it with a noise meter, I won $100 off a Tesla owner when his Model Y was 3db louder at 90 kph than one of my twin turbos.

Change over to a silicone-based brake fluid, 10+ year fluid change intervals.

Ouch, silicone brake fluids no thanks, tried that. Soft spongy brake pedal due to silicone having a poor bulk modulus, which means it compresses up to 3 times more than glycol-ether fluid when pressurised.

I've a Honda HUR216 and EGO.
I've not used the Honda since buying the EGO.
Torque is KING when it comes to spinning shit, you know, like the blades under your mower?

You mean getting things spinning? Torque is pretty much irrelevant once it’s moving.

If you would drive a car that hasn’t had its brakes serviced in 10 years, you should have your license revoked for the safety of all other road users.

Which brand did you try?
I didn't have that issue, and it saw high heat cycles with my use.

What keeps things spinning when encountering load?

There's a difference between negligence, as insinuated; and regular checking of rotors, pads, and fluid levels.

Do ambulance use EV?
Imagine being in a life threatening situation and the battery dies?

Being an Emergency Service Vehicle, they would have a small Engine in the vehicle as a backup

Motul, Penrite, Bellray, Willwood, OTK, Castrol, Bendix, Putoline, pretty much every brand that we could find over the 6 months of testing. There is no escaping the science, silicone just has a poorer bulk modulus than glycol-ether. It also provides less lubrication so we noticed excessive caliper piston and bore wear even after less than 12 hours of hard use.

Would you send an EV fire truck into a blazing fire?

 

[Memberberries]

Face facts.
An EV fire truck, in a zone with fire, is a disaster waiting to happen!

So… servicing?

With vehicles, torque helps at any speed. Best off the mark, but more torque means more speed when accelerating even at high speeds for quick overtaking.

Hybrids are different though as hybrids tend to only give torque off the mark. But EVs pull torque at high speeds. But I don't think their high speed torque is as good as an ICE.

I owe you and others an apology.
My recollection was dot 5 silicone, when it is dot 6 equivalent ether/ester-based brake fluid, with a 10-year service life.

Would you send an EV fire truck into a blazing fire?

Carrying crew, water, supplies, and the like to a staging area?
Yes.
Carrying the crew and water to fight the actual fire?
Hell no!

With the waiting times in hospitals, the ambulance would have plenty of time to charge at the hospital!

 

[SexBomb]

So… servicing?

So we can agree that it is not negligent/dangerous to not replace a fluid if used according to the manufacturer's specifications?

But batteries when charged wrong will give incorrect percentages.

After 5 years you cannot trust battery power!
I can't anyway.

I agree, and would expect the service life of the vehicles would allow for such.
Yet, knowing the incompetence of the public service sector…
