At the time I was referred to a local municipality that was using it in all their vehicles. Police, fire, other emergency vehicles, maintainence and construction type vehicles, & everthing that had brakes. At that point their service department supervisor stated they had been using DOT 5 for over 5 years, and had virtually no problems. That was quite a testamonial to me, and so I started to use it whenever brake repairs were necessary. Other friends followed suit or had already started using it. This product is especially beneficial to people living in high humidity areas, or areas where temperature changes create moisture or dampness conditions. Except for occassional stop light switch failures, I have never had or heard of any other problems related to using Silicone brake fluid. It is however, absolutely necessary if converting to this fluid to do it right. You must first bleed the entire system with denatured alcohol (available at a drug store or paint store), then take apart all brake cylinders and master cylinder and clean with the denatured alcohol. There is no residue from the alcohol since it will evaporate. Once you reassemble the system (use new cylinder kits), you will probably never have to replace the rubber parts again, and will should never have pitted cylinders again. I can only add if someone says to you that DOT5 Silicone brake fluid shouldn't be used, that person probably stills prefers to read by candlelight! Bill Borton |
