Well at the risk of being called crazy I flushed my brake and clutch today. They were done 5000 miles ago on a service plan at the dealer.
First the brake fluid was honey to a bit darker in color.
The clutch same color. When I took the lid off the clutch it was gray sludge city again. On the service I was called out to see it. It was not as bad, but the reservoir took a lot of q-tips and clean rags to become spotless. Even into the two valve holes was bad.
I would like to know what is wearing, or creates this sludge?
On the brakes, does flushing them as I did get to the ABS unit? I guess I should have found some gravel and made the ABS kick in a few times before the change? I do remember a jumper to massage it, and will get that made.
Anyway $4.00 for fluid, everything was run clean on each bleeder, I use a piece of tubing into a bottle on the 10 MM, and a mighty vac connector and hose for the 8 MM, but no might vac, just pump and hold, close the bleeder, I drop a strait edge razor blade into the two fronts to stop the gushers of brake fluid when pumping the front brake and clutch levers.
I use a baster to suck the fluid out of all three reservoirs, clean them well and fill with fresh fluid to start the flush.
Took me about 1.5 to 2.0 hours but was going slow as I wanted to make sure I introduced no air, and it was my first time doing it.
Anyway a picture(or two)is worth a thousand words............
note that you can see the casting in this one.....
And then I ran a quick 100 miles off to see if it all works, and it does
