What does ASE say about brake flushing?
Advertising Supplement taken from USA Today April 17,2002 – ASE’s Guide to Auto Maintenance Protect Your Auto Investment Probably the most ignored fluid in your car, and the most important, is brake fluid. Sludge will build up over a period of time and may block the valves inside the anti-lock brake (ABS) units and result in costly repairs or replacement. IN addition, this sludge may cause the calipers and wheel cylinders to leak, also resulting in repairs or replacement. SO the best thing you can do is to have the brake fluid flushed and refilled periodically, although the manufacturer recommendations vary as to how often.
