Guys and gals, I posted this on Facebook in response to questions a member had on there about mixing SRF brake fluid with other brands and hoe to flush it. I also shared some information I got from a Ford friend regarding SRF fluid impact on the clutch system seals and how to add a simple remote reservoir to use Fords' DOT4 LV fluid in that system.
Here it is;
I advised Dan A. on some ways to switch over, and it doesn't have to be that painful. 2 liters of SRF will do it using a
GM clutch reservoir and a bottle of Ford DOT4 LV you can avoid any potential deterioration in the clutch system. S550 clutch feed hose actually plugs right onto the GM nipple. To flush system I vacuum out the reservoir fluid and replace the reservoir with an auto trans version, or you can plug and cap the stock clutch nipple, but be sure to use both a tapered plug and a cap made of Viton, clamped on with a hose clamp.
Refill with the SRF and bleed about 5 ounces out of each wheel (RR, LR, RF, LF) ensuring that it is topped off between each wheel to prevent air entering system. Top off and drive to engage ABS 3-5 times, if you have an IDS or Scanner that supports the Ford ABS test function you can do it on the jack stands. This should flush most of any remaining old fluid out of the ABS distribution block. Finally, bleed 2 ounces more per wheel and top off. After each event do a 2 ounce per wheel bleed and you should have a SRF complete system. I do this flush each February to prepare for the new season kickoff at VIR.
For the clutch it's easy, I mounted the GM reservoir to the brake reservoir by wrapping a long zip tie through the mounting bracket holes, securing it just under the molding seam of the brake reservoir. This allows the stock clutch feed hose to bend naturally to the location and pushes right onto the nipple. Just fill with Ford LV and pump the pedal a few times, shouldn't be any new air in that system. At each brake bleed, I vacuum out the clutch fluid, clean the reservoir of the little black clutch dust particles and refill with the LV fluid. Simple and keeps those contaminants out of the brake system.
