Disc/Drum prop valve hook up? Pics?
So I got some discs and didn't have the right valve. So then I got a valve/bracket/lines for mounting it, but now it looks like the lines from the valve to the brakes are all wrong.
So do I need to get new lines for the front too? It looks like on in the front and one out the back where as my old setup was both lines out the bottom. Pics would be great. Thanks. |

Re: Disc/Drum prop valve hook up? Pics?
Dave, I have the same bracket and valve (1/2 ton) that's in dwaight72's pic. I hooked up my front line last night with a 1/4" to 3/16" brake line reducer fitting. I still have to hook up the rear line that goes on the back end of the valve. I'm going to see if I can get by with a 8" section of 1/4" brake line to connect my existing line to the back of the valve. I got my setup at a junkyard for $5.

Re: Disc/Drum prop valve hook up? Pics?
Thanks to you both. Looks like a short section and some reducers are in order. I hope to get everything plumbed this weekend, but I doubt I will get everything bled because I need to finish the rear bags.

Also the lines are different between 1/2 and 3/4 ton from M/C to prop valve
1/2 ton - front to front rear to rear 3/4 - ton front to rear rear to front
