Bleeding Brakes

I got my jeep running this weekend [img]/wwwthreads_images/icons/tongue.gif[/img] and had some issues with the brakes. The jeep has a new master cylinder and all new lines. I bled all the lines but the brakes still aren't what they need to be. (I didnt bench bleed the master cylinder cause there was no fluid in the lines to begin with.) Is there something I'm missing or do I need to go thru a couple more bottles of brake fluid? TIA

Re: Bleeding Brakes

1) I'd pull and bench bleed the master first. Due to the angle that the master is bolted to the dash it may not allow all the air to escape through the intake hole or the lines. Get two old brake lines and connect them to the master and then bend them so the other end goes into the fluid resivor. That way your recirulating the fluid without wasting it. I also tilt the master in al different directions, you will be amazed at all the air bubbles you will see.
2) Do you still have the proportioning valve in your Jeep? If so some of the books will tell you to use a factory tool to hold the proportioning valve a certain way when installing new lines/fluid.

Try ...

Try removing the brake fluid sender that is part of the brake proportional valve, then bleed the brakes again. That worked wonders on my '75 CJ5.

You might want to pickup a vacum bleeder ($30). These things work great, just dont drain the Master Cylinder dry. It's very easy to do.

The cheap way is to gravity bleed, just open all of the bleeder screws and let it go for 30 min. Just dont drain the Master Cylinder dry.

Good Luck
