O.K. guys i just bought a 88 dakota and it has a brake line leak just behind the drivers door there is a junction block i guess you would call it, it actually looks like a little master cylinder. it has a return spring and a lever and a plunger, does anybody know what this is? and where can i get one. Also where is the most reasonable place to get front wheel hub and bearing assembly.

 

Try autozone for the bearing...I'm not sure what the other part is...do you have a pic you can post?

 

I figured it out the thing is called a ride height sensing proportioning valve it adjusts rear brake pressure on how your truck is loaded. well it is gone now plugged the line off and ran a new brake line to the rear and it"s gone. Bigowe
