Brake fluid change?
Does anyone here actually follow Ford's recommendation to replace brake fluid every 2 years in an F53 chassis? For decades I've been using synthetic fluid and changing every 4 years. At that interval,...

HOW does moisture get to a Brake system?????? Just removing the reservoir to check fluid level is NOT going to introduce moisture(humidity) to contaminate the system. The OEM recommendations (IMO) are CYA for them. A Motorhome would be a 10 year flush and replacement. Automobile--Never. How many people out there have had an actual first hand knowledge of a Brake Failure problem/accident that was determined to be a failure to flush their Brake fluid? In 50 years of driving and 40 years in the RV service, I have never heard of such a problem on Motorhomes or Auto's. Doug
newer vehicle reservoir is more moisture resistant than those of the 1960's, but by no means are imune to water introduction. Water molecules are very small, smaller than oxygen, Nitrogen and most other gases. As a result water can and does penetrate many plastics and through reservoir caps.
As for failures on vehicles I've worked on, (but not maintained by me) back when rear brakes were drums, water in the fluid was often the cause of rear wheel cylinder failures which was pretty common on higher mileage vehicles that hadn't had brakes flushed. On mine, never had a rear wheel cylinder failure, but I flushed lines every year.
