Putoline, DOT 5 silicone brake fluid. 500cc

500cc bottle. A silicone based brake fluid. It offers a very high dry boiling point that exceeds 260°C; is non-aggressive and safe for paint; plastics surfaces; clothing and such. DOT 5 silicone will not absorb water like regular brake fluids do. DOT 5 silicone is not very foam resistant and therefore not compatible with ABS or ASR systems. DOT 5 silicone cannot be mixed with other 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...
