Normal brake fluid is glycol based. Dot 4 is a higher performance standard and is VW recommended. Dot is silicone based is not compatible with DOT 3 or 4.

If so, and I have the old DOT 3 in my system, must I flush all that fluid out to get consistant synthetic-only fluid? Any can anyone tell me of a case where synthetic DOT 3 was NOT adequate for the job of stopping our small vans.... Larry Ga. PS. I'd like to stay with what I've already got in the system, synthetic DOT 3 and I have a hard time believing my little daily driver van needs a HP, hi-temp. brake fluid so tell me how I'm wrong? Any case studies where DOT 3 was not adequate.... |
