  • 13" Cobra brake project back on track

    Well, I finally got my tax refund, and I sold a 97 Camaro axle I have had
    in the garage for a few years, so I made the order last night. Hopefully
    they will be here next week sometime. This is what I got for $626 bucks
    including tax/shipping:

    I decided to go with the all aluminum Mach 1 calipers, they are identical to
    the Cobra, but have no markings (price includes pads). Set : $179



    Since I am giving the whole GT front setup to my dad, I needed two new
    brake lines, these are as cheap as stock rubber. They are stainless steel
    braided hoses with teflon inners, and have the correct bolts. Set : $60



    For use with the "Cobra" calipers, I needed 13" rotors, I decided to get the
    most impressive looking, so there would be no doubt that these are some
    awesome brakes. Here is the latest technology/style, zinc plated & cross
    drilled with slots. The zinc plating keeps the surfaces that the pads do not
    touch from getting all rusty looking. Set : $170



    The reason I got this GT brake setup for free was that the rotors were a
    bit scored, which includes the rear rotors. Wanted rotors that matched on
    the rear, I went with the same design/style rear rotors (zinc). Set : $125



    Plan is to go out to a rarely used stretch of road this weekend & mark off
    a section for some 60-0 stops with the GT setup before I upgrade. That
    will give me some numbers I can post. I dont expect it to be much, if any,
    better then the factory setup when it was new, if memory serves an Avanti
    stopped in 139 feet from 60 back in 63?? Anyone have those results? The
    main improvement the GT brakes would have is repeatability. Not sure
    what to expect from the Cobra brakes, I figure that without anti-lock, it is
    going to have a point where the tires will just lock up. I am curious of how
    it turns out, but this is still less $ then if I bought even the cheaper Turner
    front & rear disc kits. It also fills my 17" wheels, which is what I wanted. I
    also found a local CNC machinst that wants to make brackets, his bid was
    the best so far, but he hasnt replied back to my Email - keep yah posted!

      Thanks Dan ... I would like to CLARIFY before I get ripped for the
      comment on the Turner brakes. I MEANT "cheaper" as in less cost, the
      front and rear setup that I was going to get from Steeltech was a tad
      more money then the Turner front and rear disc setup. It WASNT a pot
      shot at Turner - just FYI (gotta be REAL careful on here).

            Thanks.. I am going to TRY and turn over a new leaf, I am a Taurus
            so dont expect perfect results from me, the brakes should be fine.

              From the pictures you show, DON'T STOP NOW!!! (no pun intended) This looks great! My previous post still applies. I've started saving my money. 2 months ago you said this would be a good addition to my Challenger. I'm leaning your way!

                Well I guess the proof IS in the pudding, but its not that I didnt WANT
                to keep moving on the project. I just dont have excess money stuffed
                in a matress.

                If you think that the calipers look neato, wait till you see them on
                the 13 inch drilled and slotted rotors. hehe. Here is a teaser on
                an early Mustang.



                I decided against the red caliper since I didnt really want to have an
                emblem or "Cobra" printed on it. The Mach 1 calipers are identical,
                except plain black. This will also match the rear calipers which are
                also plain black. Between the start of this project, and my order the
                site that I bought from (Stangsuspension.com) started making the rear
                matching drilled/slotted rotors for the GT rear disc brakes. So that
                means it will match all around.

                  The rotors came friday night, a welcome surprise. I havent checked the
                  hub clearance with the set of unmodified hubs yet, too many other things
                  in 'normal' life get in the way. But I took some pics this evening.

                  Judging from THESE pictures .. can anyone guess what ELSE I bought this
                  past week? Friday night to be exact. The hint is its not IN the pictures.

                  Front rotors :





                  Rear rotor :



                  Front and rear rotor :



                  PBR Caliper on front rotor :





                  A little comparison between the factory rotor and the Cobra rotor :






                  Opening the boxes made me say "oooooooo , aaaaaahhhh" kinda like you
                  hear when people are watching fireworks. With the zinc plating, they dont
                  have that gooey grease on them to keep the rust off like the Autozone GT
                  Mustang rotors I bought.

                    Tom,
                    Those look great! Can't wait to see them on the car and see how your 0-60-60-0 stats are.

                      Tonight when I got home from work, I finally brought the two front drums
                      into the garage and pressed the hubs out. I cleaned one of the hubs up a
                      bit and then the moment of truth - will it fit inside the Cobra rotor without
                      any modifications?! The answer?? YES!!! :P :wink:

                      Here are the pictures to prove it ...

                      Stock hub, just removed from drum :





                      Sittin on the edge of the Cobra disc, thank goodness that ugly rusty thing
                      is covered up by the sexy Cobra rotor!





                      You can see ... NOT modified



                      SUCCESS!!! The assumption was correct ... wheeeeeeew!



                      Dead on from above :



                      Little off to the side :



                      Fits perfect ... couldnt ask for more!



                      Closeup to show the rusty untouched surface, plenty of room!



                      Thats a big load off my mind. Now to order the longer wheel studs, drill
                      my holes for the inference fit for the knurls. Then to dril the holes in the
                      rotor to the next SAE size from the stock metric. There is an option here,
                      you could have each stud turned to fit the rotor, but I would rather drill
                      the rotor holes a little larger, it goes MUCH quicker! :wink:

                        Brakes look great especially as the calipers are "Made in Australia" Good ole aussie technology. Good luck with them.

                            They are considered to be the best factory available calipers, being
                            used on the Cobra, Mach 1, Mustang GT, Corvette, Camaro, Firebird,
                            and the GTO (you know it as the Monaro).

                            Thanks Dan! I do REALLY appreciate your input on each post, its quite
                            helpful to get the positive feedback. I am SO glad that my assumption
                            paid off, since I didnt have the Cobra rotors I had to make the simple
                            conclusion that if the 60's Ford hubs fit inside with no modifications
                            then it stands to reason that since Stude used the same bolt pattern
                            their hubs would be similar sized, and would also fit. Logic.[8D]

                              so these are actually easier to use than the rotors you originally used? Or you turned down the hubs in the rear? In either case, looks awesome. What are the smallest diameter wheels that you can fit over the calipers?
