Most people don't realize that "the other fluids" in their vehicles have a limited lifespan...it's not just the oil in the engine and gearboxes that needs periodic changing. Many have been experiencing ABS problems, and soon you are going to hear of ps pump failures. Auto stores sell dip strips to test the moisture (water) content in these fluids. They are cheap and easy to use. If it's been over two years, flush 'em and change 'em out. Cheap insurance Spent three quality hours yesterday....hooked up the Wynn's tranny scrubber, then put in new Mobil 1. Did a flush and fill on the brakes and the P/S. Man...we both feel better
