I've experienced water in my brake system, my first hint was that the
brakes were acting unevenly.
If fact scary, when I braked I would be in another lane.
The next hint was that the fluid in the reservoir was black.

I flushed the system, yet found that the rear cylinders were damaged and
the next year found that the calipers were damaged.
I then replaced everything, calipers, cylinders, hoses, fluid etc

The right rear cylinder on my 67 BJ8 has a small leak and I am
going to replace it. When I removed it, I noticed several small
whitish/clear =E2=80=9Cbeads=E2=80=9D on and around the unit.<br><br>
As I drained the fluid, I noticed, at the beginning, the fluid had
rust in it. As it continued to flow, the liquid turned clear with
the viscosity of water. Thereafter, it looked like clean fluid.<br><br>
1. Does the fluid show any additional issues I should look
into?<br>
2. What do the small beads represent?<br><br>
I will flush the system before I refill the reservoir, bleed the
brakes and get back on the road.<br><br>
Thank you in advance!!<br><br>
