Feel free to move this if need be, Wasn't sure where to post this so here goes:

Here's the deal. I want to flush my brakes on my 250 and my suburban. With ABS brakes I was told the best way is to gravity flush them. Slower I know but no chance of compressing air into the fluid. My question is, would it be harmful to leave the engines running while I do this? IF it flows faster, I have never done this before, my only concern would be making sure the reservoir remained filled correct? Any one else done this before?

Also whats the best brake fluid to use?

This is my first diesel, (got it in March 09), so just starting school so to speak.

Once the bleeder is open, the pedal pumps pretty easy, even when you got a hose stuck into a can of fluid. Speaking of which, that's how I do it. Take an empty container, partially fill it with brake fluid, then take a piece of small diameter hose, insert one end on the bleeder and the other in the container. Be sure the end in the container stays submerged. Check the owners manual for the type of fluid to be used. Some use DOT3, some DOT4, and some DOT5. You don't want to stick a #4 fluid into a #3 system if it has ABS, can damage the module. So check the owners manual for the proper type.
