Which 990 Spyder?

[Professor]

I have to disagree with the brakes part of your statement. On our Spyders the brake pedal directly mechanically connected to the master cylinder. Under normal braking conditions the brake fluid transfers the pressure created in the master cylinder directly to the calipers and brake pads. At no point in this path is it electrical. But this path can be interrupted for the purposes of the ABS function. The VCM can also apply the brake to each wheel independently even when the operator has not pressed the brake pedal.

:bowdown: Thanks for the correction, Billy. I appreciate the information. Hopefully the first part of my explanation is still reasonably helpful to some. :thumbup:

The throttle explanation was great. Including the brake system was where you went astray.

Now you got me wondering if brake by wire is legal. I will have to do some light reading of FMVSS. (Federal Motor Vehicle Safety Standard):yikes:

My 2012 has had zero problems. It was a basic RS SM5. Then the farkles began and now it is a quasi-cruiser to rival any two wheel cruiser. Love it!:doorag:
