Especialy dual type. Mount it in a vise & put a little fluid in it. Hold your fingers ovrer the holes like chheck valves. & pump the master cyl. with short strokes. When you get fluid to both out lets you are good to go. They say money can't buy happiness. It can buy old Chevy trucks though. Same thing. 1972 Chevy c10 Cheyenne SuperIn the Gallery Forum | | | | | Joined: Oct 2011 Posts: 118 Wrench Fetcher | | Wrench Fetcher Joined: Oct 2011 Posts: 118 | i guess it won't take that long, thanks for info wrenchbender | | | | | Joined: Nov 2011 Posts: 24 New Guy | | New Guy Joined: Nov 2011 Posts: 24 | Here is the way I do it. When you get a new or rebuilt MC usually they will include a bleeder kit made of plastic fittings and short peices of plastic tube. They screw into the MC and run the lines back into the bowls, fill with fluid and pump slowly until all bubbles are gone. that way you are sure the MC is full. I have a few hard line made up to do the same thing. Saves a lot of time and brake fluid. | | |
