Bleeding the brakes question

I am at the point of bleeding my Dana 60 brakes and am running into a litle trouble. When I removed my original axles I let my brake reservior drain down. Now I know you need to purge the system, but is it necessary to remove the Master cylinder to bleed it? I remember about "bench bleeding", but can I do it while it is connected to the system? I am also using a tool to hold in the proportioning valve thing. I can't see where it matters, but I is doing that anyway. It seems as though there is still air somewhere as my pedal goes almost to the floor. What am I doing wrong with the brakes? Thanks for the help, Ricky...seeya...

Disconnect the lines to the axles, and bench bleed it while it's on the jeep. Then reconnect the lines and bleed the brakes like normal. If you're still have problems, let me know, I have some "tips and techniques" that have worked for me throughout the years, never failed.

Re: Bleeding the brakes question

Hey Ricky.

The best thing to do is disconnect the lines from the master cylinder and run rubber hoses from the holes on the side, up and into the resevoirs. Fill the master cylinder with fluid. Then press the pedal (very s-l-o-w-l-y) to the floor. Do this until no more bubbles appear in fluid as you press the pedal. Reconnect the brake lines and then bleed the system. If you have already filled the lines with fluid, you may want to drive it a short while/distance. And then re-bleed the system.

I've held onto a couple of the plastic fittings that they give you when you buy a master cylinder just for this occasion. If you have any connections at your local parts store, you can probably open a box and swipe you a set of fittings/hoses. They're nothing special, but they really help.

Hope this helps.

I beleive they sell a kit with the plastic connectors and two hoses that curl around into the MC for real cheap.

Re: Bleeding the brakes question

for one thing leave the valve for the front and back brakes alone,that way no air will be able to travel from the front to the back or even the even though your resvior went dry you should still be able to bleed the brakes from each wheel but it will take a little longer.and as you are doing this don't let the resvior go both fronts first then the backs,you may have to repeat this because of the amount of air in the system . good luck Gary

Re: Bleeding the brakes question

Ricky It seems you have been given some good advice on the "bench bleed" technique in the Jeep. After you have reattached the brake lines to the master cylinder make sure the brake fluid is topped off. Then go to the right rear brake and start your bleed there and work left rear right front and then left front. This works the lines from farthest to shortest and is the way it should be done to eliminate air from the system you may have to do this a few times to get it all out. Make sure to check the fluid after each 3 strokes to keep enough fluid in the master cylinder. This is the best way short of a pressure bleeder to get the air out.
