    CJ have a swivel bracket that doen't come with the booster. I could not find one. I used an SJ Booster and had to trim the hood frame to make it fit.

    I am swapping a YJ tub on my CJ and I will use the YJ booster.

      All right...here's a good opportunity to ask my brake booster questions.

      I have heard that YJ brakes (rotors, drums and such) have plenty (1) of stopping power but the standard booster does not put out enough pressure.

      One alternative is to use a bigger booster from http://mpbrakes.com/

      The other is to use hydraulic pressure from the PS pump. I don't know who makes this gear.

      So waddya' think

      1. OK not plenty....but adequate to stop 35s

            alot of the guys running autos out at JV swear by the vanco stuff. I've heard no complaints.

              Find a 1/2 ton Chevy truck with the hydraboost system you can cannibalize parts from it to adapt to the wrangler system. The Vanco system is basically this prepackaged, with all the correct fittings. I seem to remember if you find a v6 equipped truck, all you'll need to do is adapt the booster to the firewall, lengthen to control rod to the brake pedal and make up a custom hose assembly to the p/s pump. Itís also a good time to upgrade the pump and reservoir to a larger capacity one, and maybe add a filter/cooler to the system. Hope this helps.

                  4 wheel Power Disk brakes

                  What master cyclinder works with a YJ boster in a CJ with four wheel disks?

                  Drivers side plumbing exits would be best but not requred.

                    I just put the Vanco setup on and love it. It is obvious to me that it's going to eat brake pads/shoes since the last time I looked my rears had a good 3/16-1/4" of shoe, and after a couple rides without the hydro boost and a couple rides with it they are down to 1/8". I guess some of that wear could be from my "testing" involving slamming on the brakes many times up and down my street. The Jeep stops faster than my stock Liberty, albeit somewhat scary when doing so... It is amazing. I no longer have to stand on the pedal to get the brake force I need, and I think my right calf and thigh is slowly getting smaller. The Vanco setup has all the correct fittings and goes together in a snap. You could also piece this together from a number of vehicles which came equipped with hydraulic brakes, but for the cost of the junkyard parts versus having new stuff, I'll take the stuff that's not going to leave me stranded.

                      What did it cost you? How do you like the AGR setup? How much was it? Do you have the SB1 or SB2 box?

                      I would need special kits for my bastardized Jeep, XJ 4.0, YJ tub, YJ steering, CJ steering box…
