    8.8" Rear with brake calipers on the back side instead of facing the front of the car

    I got this rear from a site on eBay. (Every thing has been replaced with new.) I noticed from my pictures from the build school and from the manual that the calipers are facing the front of the car just opposite of what I have.

    I am wondering if there will be a clearance problem after the body is placed on the frame. Dose anybody else have the calipers this way?

    Also looking at this picture 100_2144.JPG notice that what came with the axle has the brake line routing to the front around the shock. That is all good by me. But now I have to find the proper hardware to connect to the 3/16" brake line as it is already has the banjo joint occupied. What was connected to that line was a 3/16" line which connected both calipers to a center fitting with a flex hose mounter over the differential. That had a banjo fitting on the end of the flex hose. Any suggestions of what fittings and brake lines I would need to connect to my brake line?

    Thanks in advance

    The issue is with the reach of the emergency brake cables that come with some kits. Not sure what your circumstances are but with my 2009 kit we had to mount them in reverse, forward, so the e brake cables could route properly. This is just a recommendation but I would also ensure that the tubes were welded to the third member. The spot welds alone are prone to fail resulting in a twisted tube that can be catastrophic.

    Second the recommendation on welding the axle tubes to the cast housing but be advised, there is a correct method for doing this and then there are other methods that may or may not prove successful. Not very many welders have experience welding cast steel to carbon steel and I've seen all sorts of methods and processes used. I made my living welding and have a great deal of experience welding cast iron and cast steel. If you go this route, find a shop that has experience with cast steel, uses the TIG process and 99% nickle filler. If you click on my build album, among the first photos I posted there is the process for welding the axle tubes to the housing.

    As for the location of your calipers, I prefer mounting them toward the middle of the car if all things are equal as this reduces polar moment. But as a racer I'm anal about weight -- less is better and where it's placed makes a difference. For a street car, not so much. As wrp mentioned, the brake cables (length and routing) may pose a challenge and you may have to trim the fender well for clearance. Nothing too serious. One piece of advice using banjo fittings (hate these things) is be careful using them with flex hose. They really need a hose support to keep the flexing from trying to rotate the banjo fitting and loosening it.

    I ordered mine online like you. Perhaps from the same vendor. The calipers are mounted to the rear like yours and I haven't found a reason to change them. It did take a little research for fittings but most things do on these cars. especially when you deviate from the norm. IMG_0616.jpgIMG_0630.JPGIMG_0642.jpgIMG_0878.JPGIMG_0920.JPG

    Looks like the same as mine. From the "T" fitting on the axle to the frame, what flex cable and what fitting on the frame did you use?
    Did you have the body on the frame after installing the axle?

    Thanks

    Could you guys possibly run Ford Ranger/Explorer rear brakes instead?
    The rotors are larger (11.21") and the parking brake cables are way easier to route.
    Also, the parking brake is a shoe style that is inside a Top-Hat style rotor.
    I went that route because I wanted the larger rear brakes without going to higher end parts.
    Both calipers are located in front of the axle.

    I already have the calipers and I just figured out what I need to make them work like HVACMAN did. I should have the parts tomorrow. About the e-brake, That will not be a problem either. I'll make something like this =|-------o to extend the length of what I have or switch to electric e-brakes brakes.

    When I get the parts tomorrow I'll give you all a better description.

    I will see if I can find the receipt. It's been two years. It probably came from Summit or Amazon. If I remember correctly, I installed the bracket and tee on the frame. Piped the steel lines to it. Then measured from tee to tee with the axle at full droop.

    These axles have the 94-04 Cobra 11.65 brakes. No need to upgrade.

    My son is a Master Mechanic and he looked at my situation with the rear brakes and also looking at the pictures you provided. He came up with a Napa part # 36765. It looks exactly like you have and will work fine. That # is for a late GM pick up truck.

    To mate this to the 3/16" brake line you need an adapter from Napa G49505-0403.

    I get a chance to put another GM part on my car!

    So I got my 8.8 from an '07 GT. Looking at swapping the brackets L/R to move the calipers to the front of the housing... Do the axles have to come out to remove the brackets, or can the brackets just rotate around and bolt back in place?

    Two questions.
    1) where did you find the bracket for the differential center hose?
    2) How did route the brake line to rear flex hose?

    i was planning on taking my brake line across the rear frame just above and behind the differential. I found flex hose with all 3/8 Inverted Flare Fittings, but no bracket since its not vehicle specific. All the ford rear brake hoses i find with brakets have a banjo fitting at the other end of the hose.

    Thanks in advance.

    This is a non issue.

    My calipers mount on the back of the axle as well. I used these brake cables and they routed perfectly. The only thing I had to do was go get an E clip to attach them to the housing.

    The brake line with t fitting is ac delco 18J2064

    All the parts came from Amazon and Summit. I just looked until I found what I thought would work. IMG_0918.JPGIMG_0919.JPGIMG_0920.JPGThe hard lines were on the axle when I received it.
