just purchased a '72 Eldorado and going thru process of changing fluids/filters. What is the easiest/safest method of changing brake fluid? Should I remove reservior from master cylinder and bleed remaining fluid from each wheel?

I usually get all the fluid out of the master cyl. with rags or a suction gun, just don't hit the pedal of course. Wipe out all the sludge and refill it. Then all you need to do is bleed each wheel 'till clean fluid comes out. If nobody is around to help, just leave the cover off and let it run by gravity, just keep an eye on it so it doesn't run dry.

barge master: are you removing the master cylinder to empty brake fluid or are you just disconnecting the metal brake lines from the reservior? how exactly can i remove all the existing brake fluid. this fluid is grossly contaminated and i want to make sure all is removed before replacing with new fluid.

You don't need to remove the master cyl. or the lines from it. Get a cheapo turkey baster to remove all the fluid. All the reaining fluid is going to come out at the wheel bleeders.

The turkey baster is a great idea, but even soaking it up with rags will work. Then just wipe the inside clean, fill and flow.

yeah the turkey baster sounds like an effective and inexpensive method of emptying the reservior...when your bleeding the brake lines at each wheel do you guys use the method of placing a small piece of tubing between the wheel and a clear bottle filled with new brake fluid? if so, will there be a noticable difference between the old brake fluid and the new fluid that will be flowing out after the old fluid? Or if I leave a very small amount of old fluid in the reservior and top off with new fluid, will the old fluid just gradually mix with the majority new fluid? thanks for your input
