R.O.R. You're welcome for a good laugh! I looked in the Bentley and sure enough, couldn't find any mention of a clutch slave cylinder. That's awesome! One less thing to go wrong.
As for the brake fluid flush every year it can only help prolong the life of the MC and SC. Brake fluid atrracts moisture. Moisture promotes rust. I
im aware that brake fluid attracts moisture. i live on the oregon coast, one of the wettest places on the planet. i dont replace my brake fluid every year. not even close. maybe every 5 years. it gets tested every year or two to check the moisture content.. but thats it.
im telling you that you are wasting your money by changing the brake fluid that often.
and another thing, water does make things rust, but it needs one other key ingredient for any damage to occur, OXYGEN. and if the system is full, theres no oxygen in it.
usually any damage to the brake system is from air in the lines, or from sitting with no brake fluid in the system.. if its kept up, and kept clean, then there is no reason to flush your brake fluid every year, besides to lighten your wallet, and waste your time..
air in the lines sometimes allows small rust pockets to form, and if the car sat for a long time with no brake fluid, then the first time you go and pump the pedal, it allows you a chance to push the pedal soo far that it tears the seal on the rusty bore of the brake MC..
if thats not enough reason as to why you shouldnt change it soo often, then carry on, replace it as often as you like, waste your own money. no big deal..
