    This is what you said earlier on the other section on disc brake conversion. I am just surprised that MBM advises other products.
    What would be the pros and cons of each? Can you tell? Also what is the difference between 8" and 7" boosters (except an inch)
    None that I don't believe you, I just like to understand what I am doing.

    Hi Eric, first of all you do NOT want a 7Inch single diaphragm booster... The 8" Power Booster many of us used is this one. 8" 2 Stage Power Booster MBM PB8537 or PB8537C For Chromed version. For the Master Cylinder get a 1" Bore Corvette Style Dual Master Cylinder - MBM MC1321A or MC1321CH For chromed version... Or get the flat top version MC1321CHFT (Chromed Flat Top) because I had problems with those two locking clips hitting the inside of the hood when I closed it. If you use the MC1321A OR MC1321CH, You may have to put some washers on it to force it downward a bit to clear the hood. I will let others comment on the rest of those, if needs be...

    MBM is advising the following parts for a T Bird applicaiton, is any one has any experience with those parts, why use those or others? :
    Booster Pb7001 : http://mbmbrakes.com/universal-7-sin...phragm-booster
    Master Cylinder Mc1505 : http://mbmbrakes.com/universal-1-bor...leeder-screws/
    Booster bracket Bprp6570 : http://mbmbrakes.com/bprp6570-1965-1...oster-bracket/
    Pedal Extension Pre101 : http://mbmbrakes.com/universal-2-1-2...rod-extension/
    Pedal Rod Extension Pre5564 : http://mbmbrakes.com/universal-4-3-4...rod-extension/
    Pedal Rod Extension again Pre-107: http://mbmbrakes.com/universal-3-1-8...n-with-eyelet/
    Proportionning Valve Pv2k-2bm : http://mbmbrakes.com/gm-bottom-mount...-drum-brass-1/

    The proportional valve comes with the bracket to hold it on the booster.
    I still have to receive the booster bracket dimensions to check hood clearance.
    But again anyone advise is welcome.

    I used the published list in the members only section to gather the parts and tools I need and there is no word of the brackets. I am wondering what other parts are missing??

    The MBM booster does not come with any bracket as far as I know. You have to cut the bracket off your old booster if you have one and use that. In this case I recommend using the ABS booster combo or the one that TBird HQ sells. They come with the correct bracket.

    Thank you for the pictures. Not sure to understand though. Can I install the new booster on the factory bracket? Do I need a new bracket? None was listed on the list of parts or I may have missed it.
    Also what bracket did you used to hold the valve?
    My car has no air conditioning.

    Eric, here is what my chromed dual MC/Dual 8" Power Booster looked like installed. However, in my case, because I had AC on the car, I used an adjustable mounting bracket that made especially for me to clear the AC plenum box. Some of the others, without AC, or with AC, used different mounting brackets. Some used the ABS system, as I recall, because they are the only one I know of who provides a mounting bracket designed to clear that AC plenum box... They do NOT sell that mounting bracket separately...

    When I use the MC1321ACH booster, with the PB8537C booster, do they fit on each other without any adapter and did tHe booster fit the car's factory bracket without any adapter?
    Also can I get some pictures of this set up used on cars, I would like to have ideas of how they look as I am not sure if I get them chromed or black and aluminium...

    That leaves only - 3/8" Metal or Plastic Tee for the booster vacuum hose.
    You only need the tee if you are going to reuse the metal vacuum can inside the fender well. I don't see any need to reuse it. The booster's job is to hold enough vacuum in reserve. If you really want to reuse the vacuum can those tees are common parts that are found in any auto store even in your country. I would just eliminate the vacuum can as it's one more possible point of failure.

    That brake house mounting bracket, I think, was already there for the drum brakes. I think it is an SAE bracket.

    Eric, here are answers to two of the questions you asked, and a picture of the Brake Hose Mounting Clip.

    The Scarbird GXY 1958-1960 Tbird Mounting Brackets

    https://scarebird.com/index.php?rout...product_id=224

    Here is a couple of pix of the brake hose mounting clip. I am trying to find a source for them.

    A mechanic may well come to help me installing the parts but I need to have everything on the shelf for the big day.

    I sourced most of the big parts. Here are the small bits from the list that still need to be found :
    - Scarebird Mounting Brackets Can you give a part number from Scarebird?
    - Brake Hose Mounting Clip can probably be locally sourced. Can I get a picture?
    - 3/8" Metal or Plastic Tee for the booster vacuum hose. Can I get a picture?

    After I got these, I may be all set.

    Thank for your help.

    Please understand, there is no 'one-stop shop' or kit for retrofitting power disc brakes on a Squarebird. Many of our members have already gone through this process so we know it works. There are different ways using different parts. Some use the Granada spindles, calipers, pads, etc. Some use Scarebird spindle brackets with S-10 calipers and pads. I did one of each on my classic Fords and I have no preference. Cost is widely different because one system uses some boneyard parts but as far as performance, they are the same.

    The 'list' you refer to accommodates all the parts that either system uses. In short, it covers them all but it is only a list of parts, not an instruction sheet. No, we won't shorten the list for one specific system. The main idea is to supply a power disc brake system as inexpensively as possible because no kit is available for our members.

    Anyone doing a brake retrofit MUST know what he is doing. If you're the type who changes his oil but catches the garage on fire, this isn't for you. Hire a competent mechanic. Having said that, you may learn about these systems before ordering parts. Learn about things like, Bench Bleeding a Master Cylinder because most of us never see a 'dry' M/C. Most of us never adjusted a booster output shaft, etc.

    Those of us who already went through this are here to answer your questions which can save you a lot of money, frustration and time. If you have your own ideas, then that is up to you. All I can say is, I never heard anyone say they will go back to drum brakes. My classic Ford cars will put you through the windshield when I do a power stop with my power front disc brakes. - Dave

    I totally agree with you Dave. But I still need to have the right parts and tools at hand before I start or I won't be able to do much work in 4 hours if a nut is missing.
    Car comes from Arizona, I doubt they use much salt on their trails down there. But in any case it's not a big deal to draw new lines.
    But as I said, right now I am trying to source the parts and tools...
    Still waiting to hear from MBM and PirateJack...
