Does your ABS M/C pump come on and off?

It's possible that that over time the pump will cycle more often as the seals lose their integrity and lose pressure over time. But that is just a thought.

Guys
The last post is exactly what I have noticed in all the SC430s I have owned.
I have owned 4 SCs and they range from 27K to 75K in miles.
With some SC now getting up there in age, I wondered if the failure will start
happening more frequently under higher mileage 430’s.
It appears most total failures are happening over 100Ks. Are you hearing this constsnt
buzzing from your MC? How many mileage does your SC have? Wondered if Lexus will
ever fix the MC ? This part with part and labor is about 3-4K now
