Hydraulic reservoir

[Harry Moon]

I used methyl hydrate to flush mine. I've been using silicone fluid for 40 years with never a problem but for the last few projects i use a pressure bleed system and fill the systems from the wheel cylinders or slaves. the pedals are hard right away and if replacing a brake sensor(too often grr) a quick push from the closest wheel cylinder clears any bubbles out of the system.the trick is not to create and bubble up the fluid.
