That was a point worth reinforcing Julian castor oil brake fluid (DOT 2) = obsolete synthetic brake fluid (DOT 3, 4, 4+) = good silicone brake fluid (DOT 5, 5.1) = bad for old cars (LMH+ should only be used if specifically recommended my the manufacturer, such as Citroen) Brake Fluid Specifications Dave On 2025-03-19 1:39 p.m., Julian Kift wrote:
I think folks may be getting confused between 'synthetic' and 'silicone' brake fluids, nothing wrong with synthetic and they are typically higher performing than non-synthetic, you however want to stay away from silicone (DoT 5), which is incompatible with earlier fluids and may older brake seals.
