Dan, Air bubbles will get into any brake fluid if you pressurize it while air is in the line. The trick is to gently push the fluid with the air pockets out through the bleed holes. Most people have learned to bleed brakes by pumping up the pedal until it's hard before opening a bleed valve. That causes any air that's in the line to mix with the fluid. (much like shaking a can of soda) When the fluid is mixed like that you will never get all the air out. The best method is: 1. Open bleed valve 2. Gently push pedal to floor 3. close bleed valve 4. Let pedal return to normal position. Repeat this process until clear fluid is seen coming out of bleed valve. After the master cylinder is bled, you should bleed the wheel cylinders starting with the one farthest away from the master and work towards it. 1. Right Rear 2. Left Rear 3. Right Front 4.

I have replaced all lines, wheel cylinders, master cylinder, and any other brake part possible, on my '65 300L (w/ Imp 440 - required content). I am now going to hook everything up, use DOT 5, bench bleed the MC, and bleed the brakes. A note on the web-site suggests that DOT 5 has a tendency to get air bubbles. A suggestion is to heat the fluid up prior to using to eliminate the air bubbles. Here's the question: I'll assume I don't want to boil it - just a nice simmer? ... for 15 minutes? ... 30 minutes? ... until it reaches a certain temp? If someone can offer insight, I would greatly appreciate it.
