So about 3 months ago I changed my rotors, pads and replaced lines with ss ones. I also flushed with new Motul RBF600 fluid. Since then I have done 2 auto-x events and 1 track day. Yesterday I noticed that my car was not stopping that great and the pedal felt a little spongy. I checked my fluid and to my surprise it was cloudy and looked like it had specs in it (see pic). I believe this is a sign of water, how could the fluid of collected water in just 3 months? Any ideas? I have some ATE super blue on order to do a complete flush again.

 

Motul RBF is extremely hygroscopic (correction - all racing fluids except Castrol SRF are extremely hygroscopic). There are tales of open cans left sitting on the pit wall at hot and humid race tracks absorbing so much water that they overflow in the course of a few hours.

Yours doesn't look too bad, actually, given the weather you've had in that part of the world.

I'm a big fan of Castrol SRF. It's got the best wet performance of any of the racing fluids, and I get a full season out of one bleed/flush in the spring. I use titanium plates on the front brakes.

 

I just wasn't expecting the cloudiness after 3 months. But taking the hot weather maybe it's expected.
