so, what can be done about the rear brake proportioning valve? it seems most people replace it with a "t" fitting, but that doesn't seem to address the issue. it must be there for a reason. can it be rebuilt? can it be replaced? how can one tell if it is working properly? what is the best way to bleed the little beggar?

i appreciate all the help and information. soon i'll be able to tackle the brake project, now that the holiday vortex is loosening its grip on my life. |

Found this on the bird board. Prop valve exploded and explained. Apparently it can be rebuilt and adjusted.
airsix is right, but much of the chronic mushiness in the brake circuit can be eliminated by completely bleeding the rear circuit ahead and behind the proportioning valve before bleeding the brakes. Like most brake tasks, it is more tedious than difficult. Just make sure the valve itself is completely free of entrapped bubbles. It helps a lot. |
