https://msdspds.castrol.com/bpglis/F...JAE-B8VK5T.pdf I’ve been using SRF for roughly 25 track days from June 2018 to last weekend. I’ve gotten the brakes hot enough to discolor the calipers (as many have), and to heat check the rotors. Pedal has never gone soft. I’ve done a full flush twice, and a couple bleeds in between. The fluid I’ve removed has been close enough to new in color that it has been difficult to identify the fresh fluid when flushing. First flush was at the start of the season, and second was when I rebuilt the front calipers due to slightly uneven pad wear on one side and cooked dust seals. I’m confident there’s no need to flush more often than 1x/year. Agree with others that it’s long life and consistent performance is worth the added cost, and probably comes out cheaper in the long run vs more frequent flushes with other fluids. |

All brake fluids on the market, except SRF, are hygroscopic (yes, hygro) and they absorb moisture. Wet boiling point is indication of boiling point at 3% moisture in fluid. However, SRF is hydrophobic (yes, hydro this time) which means it repels water. That is good. But, that means that you have to flush your brake system thoroughly as it will repel moisture from old fluid and create bubble. So, if using SRF, thorough flush is a must. Now, SRF will not perform any better than ATE TYP200, RBF, TRW Racing etc. when new. What will do due to wet boiling point is allow you less to flush less often, once a year maybe. But, IMO initial flush should use 4 bottles, and they are expensive. |
