Hi,
Tomorrow, I'll be replacing one of my rear brake callipers. After this I'll need to bleed the system but I was wondering if I can use old but unused fluid to fill up the reservoir with? The plastic bottle that that fluid has been in is about 2 years old and the bottle has been opened before.
Any objections?

Don't use it!
Brake fluid absorbs water, it will almost certainly be contaminated.
New fluid from a sealed container is required.

Re: Old hydraulic fluid?
That was a pain. The nut securing the hydraulic tube just would not turn! First I rounded it off with a number 11 spanner, then I tried it with self-gripping spanner and that just rounded it off some more. Had to go to Homebase and get that pipe grip thing to finally free the nut.
The grinding noise was actually a completely stripped brake pad on the back of the disc. As the calliper is completely seized, only the piston pushed pad was actually doing anything. The pad on the front of the disc hardly had any wear.
Anyway, all replaced, brakes bled - seems OK and no noise any more.
Didn't feel like tackling the rear top links. Access to awkward and I lost some of my tools somewhere
Will get a garage to do that.
