1 liter bottle. Silicon based. Non aggressive for painted surfaces; plastics. DOT 5 is non-hygroscopic and will therefore not absorb water. Not compatible with anti-lock brakes. Developed for use in stock and aftermarket H-D V-Twin models. With characteristics that can be trusted to give the ultimate performance for your bike in all circumstances. Proudly engineered and manufactured in The Netherlands. Note: Do not mix with DOT 3 & 4 brake fluids.Tech tip: If you want to use DOT 5 may be easier to decide if it''s right for you with some added knowledge about this type of brake fluid. DOT 5 silicone is non-aggressive for painted surfaces; plastics and has anti-corrosive characteristics; is non-hygroscopic and will therefore not absorb water. Great characteristics for vehicles that are not used much. However; when water accumulates in the brake system over time; and it is not absorbed by the brake fluid; in theory it could create pockets of water which could boil in extreme circumstances. This could result in vapor lock and total brake failure. Since DOT 5 silicone does not absorb water the accumulated water may not fully be removed from the brake system when the brake fluid is changed. DOT 5 silicone may never be mixed with DOT 3 or 4 brake fluids. It is also not compatible with ABS (Anti-lock Brake System) or ASR (Anti Slip Regulation) since it will foam easier. Note that the H-D Motor Company has used DOT 5 up to around 2006; about the time when ABS was introduced... OE
