In this clip we're going to talk about the proper service procedure to inspect, remove, and replace your steel brake lines and bleed the braking system on a Ford Explorer. In this step we're going to talk about the proper way to reinstall our custom brake lines. We'll talk about the routing methods and the procedure for tightening and torquing our fittings. I'm going to custom bend and fit my new brake line to the driver side rear wheel cylinder. Your going to want to follow the contour of the old lines as closely as possible and reinstall the line into the factory connections and retainers on the axle. What I'm going to do first is screw the fitting into the wheel cylinder, here, and then rout along the axle line up to a clip here, then down around, and up into the brake hose. you want to be careful when your bending brake lines. Just do to location you can't use a tubing bender. You can't kink brake line, if you kink it the line is damaged, destroyed, and will have to be replaced. What you want to do is make very gradual, slow, and easy bends working along with your thumb; just like so. What I'm going to do now is start it into my wheel cylinder. It's a good idea to just leave it finger tight an tighten all your connections at one time. Go ahead and run it down as far as I can with my fingers, just like so. I'm going to take and put those gradual bends into my line and follow the axle keeping it up and away from anything that may damage it along the road. Clip it into my clip there. You want to follow the axle as close as possible, paying attention like I said, specifically not to kink the brake line. Alright, go ahead and screw my fitting in into the brake hose. There you go. Make sure my hose is following the axle as closely as possible and is up out of the way and that it's not going to rub on your shocks or any other body parts. Go ahead pop this vent hose back on. Now I'm read to tighten down the fittings and hammer down my retainer clip. Alright I'm using just a regular wrench here. Since all my fittings are new a line wrench is not necessary. The number one cause of damage to hydraulic fittings is over tightening so you want to take care not to strip them out or damage them in the installation process. Right there is good. I'm going to go ahead and move up to my wheel cylinder line and tighten hat down as well. The same process lefty loosey, righty tighty kind of bull. Alright I'm going to use my hammer to tap the factory retaining clip back down onto my brake line and like I said you're going to want to use the factory connectors and retainers any time humanly possible. Give it a wiggle, make sure it's there. That is the proper way to hammer down your retaining clip and reinstall your new brake line.
