Doin' the double flare boogie!

Well, the brake lines are all run. Now to add some brake fluid and test for leaks. Sure hope there aren't any because making double flares in brake lines is a pain in the backside! I still have to install the clamps in various spots and that means drilling a few holes. The bracket for mounting the proportioning valve is being held temporarily with vice grips. Once a couple holes are drilled, the bracket will be bolted to the frame. Keep in mind that since the master cylinder is mounted backwards, the back chamber feeds the front brakes and the front chamber feeds the back brakes. The blue and red cylindrical parts in the lines are the residual valves. A 10# valve is used in the rear and a 2# in the front. First pic is the driver's side front.


Next is the inside of the driver's side frame showing the T connecting both front brakes to the residual valve.


Here's the inside of the front cross member.  I chose to use a coupling in the passenger line.  Much easier than trying to form one continuous line from the T fitting to under both frame rails and across the cross member.


Next is the connections to the master cylinder.


This picture shows the lines as they contact the frame.  A vacuum pot was installed where the ring is showing on the frame and was held in place with two bolts.  Those bolts were very convenient for the line clamps.


Here's the driver's side rear showing the 10# residual valve and the proportioning valve. The brake line runs through the upper shock mount.



This last shot is the connection to the rear end.  Those brake lines were installed last year.  I simply rerouted the flex line (that black brake line running to the rear end) so it attaches to the rear of the T fitting rather that the front.  I needed to bend the tab that is welded to the rear end housing to create the proper angle.  You can also see the cleaned and painted gas tank.
