Brake system?

I'm waiting on my M3P. I wondered how the brake system works. Is it hydraulic like current ICE cars, or is it electronically regulated?

It's a normal brake system, uses brake fluid (so hydraulic) with a Bosch brake controller for ABS and stability control. For track use, many of us are upgrading the brake fluid to a higher temp one and also swapping brake pads to again be more tolerant of high temps. The stock parts are more about ride quality and low brake dust which isn't very fun on track

Regenerative braking happens via the motor, so the brakes aren't impacted at all by the regen braking (they just work less) but they still function like an ICE car. The regen braking is very similar to being in a low gear in a manual car and lifting off the throttle, the car naturally wants to slow itself down without touching the brakes at all.

Just remember to do a few hard brakes each week to keep the pads clean and limber especially if you live up north, this came from a tech at a Svc Ctr in regards to taking care of the brakes. True you will not use them as much but they still have to be tended to and not overlooked and again if up north an annual cleaning and lube the slots is recommended to keep corrosion from setting in and binding up the proper movement of the pads. Remember, corrosion will set in with little use of the pads and that means pitting, not good, which could lead to replacement, double not good, so exercise the brakes weekly and don't rely solely on the regen to do all the stopping.

And if you ever get to the point of needing to replace brake pads DIY.
