brake fluid capacity?
I've checked my repair manuals, owner's manual, the Net and do not find anything.
Is the brake fluid system capacity a secret?
Has anyone replaced their brake fluid and know how much was needed to fill the system back up?
Thank you

You fill the master cylinder, and then start bleeding. Make sure that with each press of the brake pedal, you don't run out of fluid in the ms or you have to bleed all over from scratch. Once you have finished bleeding all four corners, you just top up the ms to the full level.
As for how much fluid to purchase. Not sure. Buy a few pints, and you can return what you don't open.

depends if you have the hydroboost system or vacuum booster as they have different size reservoirs.
if you have the hydroboost system you will need 2liters. suck out the old fluid from the reservoir then add new fluid....this will take close to 1liter. I would use the 2nd liter to bleed the system at each bleeder screw. If your brake lining and rotors are all new; top the system up to the full mark. if the linings and rotors have wear, top up to a slightly lower level.

Brake bleeder valve wrench size?
I checked the size of the bleeder valve "nut" before starting work and find that it is 10 mm with a gauge but a 10 mm wrench is not tight on it. 10 mm is not close to any english standard wrench size I am familiar with.
I certainly wouldn't want to round off the nut if they are on tight.
Has anyone bleed their breaks and know what size the bleeder valve "nut" is supposed to be?

Damaged Brake Bleed Valves ... Brake Fluid color
After the fact:
A 10mm wrench was the least of my problems.
Working my way around the van - pass. rear, driver rear, pass. front ... I find both the front bleed valves are gnarled and seized.
Weeks of intermittent application of PBBlaster and patience with vice grip pliers, a blow torch and some heat protection on the flexible brake line got them off.
----------------------
NOW -
I have run two quarts of brake fluid through the lines and it is still coming out tinted.
The fluid that was in the lines was the color of black tea. Given how bad the front bleed valves were chewed up I would like to assume the brake fluid was changed at 30k ... and can accept that that may be wishful thinking.
I suspect not only contaminated fluid but corrosion of the lines.
Does anyone have experience with flushing brakes that can tell me tinted is as close to clean as it gets ...
OR
that since the fluid was so dirty it is recommended to flush the lines again in some number of months or miles?
