    Background : I'm upgrading Tonka to 11" brakes with a dual master cylinder. I'm considering using SS lines.


    Observation: Suppliers sell a number of different CJ5 SS brake line kits based on model year, specifically for the years 67-68, 69-71, 72-73, 74-75. Nothing for pre-67 :(.

    Option: Along with the brakes (from a '76 DJ5) I also got a little four port doohickey that may be either

    A)- a proportioning valve
    or
    B)-just a handy place to mount the brake light switches.

    Oxymoron: I want to retain the stock look/routing.

    Question 1: Which year kit should I order that will work with the dual MC, optionally with the doohickey, & keep the same (or close to the same) routing, including how the hoses mount at the ends of the front axle ?

    Question 2: Anyone know of an online source documenting the various brake line configurations for the years in question ??

    Querstion 3: Does anyone know if there are wheel cylinders that will fit the 11" backing plates that have smaller diameter pistons, i.e. 15/16 vs. 1" so as too eliminate the need for the front/rear proportioning valve ?


    Thanks :),

    1) wagner lists 2 different dual MC's, one of them has a flip top and might require push rod be made shorter. The other is listed as a dual rear wheel, has the bolt down top and uses the :v6: style pedal (no longer made. :( ) I used the dual wheel one with herm's bracket. to use the :hurrican: pedal one needs to make a bushing to expand the stud to the larger :v6: hole.

    3) I used the same 1 1/8" wheel cylinders front/rear. figure I can aways add a valve if it's needed on the rear line later.

    Howard,
    Don't have specific answers for ?'s - just wondering why you're looking at SS tubing and why you can't use the existing lines as patterns to bend your own? NAPA sells a good bender that will do 3/16, 1/4, 5/16 and 3/8 (think it was $7-$8).
    Excellent opportunity to broaden your knowledge and hone your skills at bending tube (stress management therapy). R) R) R)
    Piratejack.net has good brake info as well. I bought a metering valve and residual pressure valves from them.

    As always - good luck!

    :voice of experience on: if you buy stainless lines and you have to change one of the ends, get out your sailor's dictionary because you will need every word in it. :voice of experience off:

    if I had it to do again I would save the money and buy mild steel lines, if I get enough rust to go through one of the lines, the rest of the jeep will be toast as well. $0.02

    Yeah, I think that's right - the SS lines may last forever, but the steel lines will last 30-50 years or so. That's probably long enough for most owners.

    Dan, I could go into a cost/benifit analysis breakdown or I could quote an engineering study on the superior properties of 302 stainless over regular tubing.

    I could simply state that I want to do this once & never have to worry about it again.

    I could ... Oh, what the hell, the real reason is-

































    I like Bright Shiny Things :cry:





    There, I've said it.

    My Father liked bright Shiny Things.

    His Father before Him liked Bright Shiny Things, as did his Father's Father before that.


    I'm not proud of it, but there it is.

    Don't some states (PA?) require stainless lines in order to pass inspection?

    Sure - just add CP in front of the PN's and tell the parts guy someone from Texas swore that they were right. R) R) R)

    Rear brake hose Wagner F80028 (BH80028 )
    Brake shoes NJA BS228
    Hardware kit Wagner F87352S or Autozone H7137
    Speedbleeder HELP rack #12701 3/8 x 24 - 1.19 long

    That's all unless you need front disc brake PN's for 79-86 CJ or stock MC and stoplight switch. :)
