I know Most probably never will do this service.
I'm just curious how often for those who perform this service - How often be it time or mileage?
I normally start with the Back/Passenger side & begin the flush - Then to the Back/Drivers side - Then to the Front/Passenger side - Then Drivers side. (I have my son - continually adding Fresh Brake Fluid into the reservoir) while my wife pumps the brake. (I watch the flow out of the caliper).
I have it in my service to do schedule - Suck out the Reservoir & refill every 25K miles & to perform the Full Flush service every 100K miles - with Castrol (synthetic) brake fluid.
I was just curious if I was the only one who performed this service on a regular basis.
I do understand that I might be the Odd Duck & have plans on keeping his 6.7L for more then 4-5 years - If I was only keeping her for a short time - I probably wouldn't even bother.
But since this is my last Truck Purchase - I'm servicing every system on a regular routine schedule.
