    It was time for a brake job on my 67 coronet.
    It needed pretty much everything 10" drums, cylinders, hoses , shoes the works.
    I had read in mopar action Erinburgs article on the Scarebird brackets and parts list for a disc swap. So away I went. The brackets and hardware from scarebird along with parts list and instructions came in at $113 with shipping.
    My local bill at my automotive for calipers , shoes, and hoses was $120.
    A set of Ford/lincoln 10.5 rotors by raybestos off ebay was $41 So all in for $274.00
    This is a manual not power set up sized to work with the manual master. I went with the 10.5 set up so I could retain my steel 14" wheels.
    My master cyl. is in good shape so no change there.
    With this setup you reuse your original hubs. My bearings and races were good and just needed trip through the parts washer and a repack. I had a pair of seals for the hubs.
    I've had it out just around the block a couple times because of weather no real hyw. Test but the around town and pedal feel is great.
    If needed I may have to install a proportion valve in the rear line but I will wait until spring and get some testing on a wet road ect. 20220108_131053.jpg

      Thanks! Nice write up. So which rotors exactly are these?

      I could probably do 10 of these in a row, everyone is always asking.

        I’m waiting for the Scarebird rear disc kit to arrive in the mail any day now. Can’t wait to get it.

          91 lincoln mark V11.
          The fit on the hub is tight , I did a little clearance on the hub hole with my die grinder and knurled bit, couple swipes around and she slipped right on.
          Scarebird warns about the tight fit in the instruction sheet.

            So you are using a drum brake m/c? Not enough capacity for Calipers when the pads wear down...

              ^^^^ This. Make sure you have the larger front reservoir on the master for discs.

                    Rear reservoir goes to the front brakes, front goes to the rear brakes.

                      Interpretation is key @Red63440 as maybe my Canuck speak confused you. Yes the larger reservoir is on the rear of the master, but the larger "front" reservoir, meaning for the front brakes.

                        I thought that the Celebrity was only made until 1990?

                          I spent some time (unsuccessfully) tying to see what other calipers there might be that would bolt up to the Scare bird brackets. I would use that kit except I don't want a signal piston caliper.

                          Thanks for the info. A disc brake conversion is in my future. I have a brand new master I bought for a large single piston caliper set up.

                          I see they offer another set up that uses Cordoba 11 3/4 rotors and the same calipers, for almost twice the money. How much difference would the larger rotor make with the same calipers and pads?

                            This one?
                            https://scarebird.com/index.php?route=product/product&path=64&product_id=158

                            If so, was that die grinder exercise because of this?
                            "We include the brackets, banjo bolts, cotter pins and hose locks. The rotors will require the center hole to be opened up on a lathe approximately 0.030". We can sell rotors ready fit for a modest fee: click here"

                            Yes Ed, looks like the same brackets I ordered.
                            I do not think it needed .030 more but I am sure different hubs and rotors are a bit different.
                            I only had to make a couple rounds inside with the bit and they slipped right on.
