    I am looking at another mav that has 4 wheel drum manual brakes. I have the complete disc/drum power set-up on my ditched '77 project. Will I have a ton of problems if I want to swap the manual brakes to power AND add the discs, or should I just add the discs and stick with the manual master cylinder with no power assist OR, can that even be done? Could use some direction guys, help me out.

    Its a pain to put the factory power set up in. PLus you cant run a manual tansmission. Most will agree, including me, its not really needed. However, There is a world of difference. The power set up is much nicer. I will probably add power brakes to my future car projects, but it will not be the factory set up. There are more compact solutions out there.

    Is changing from front drums to discs just a bolt on deal or will I have to change spindles?

    So, manual brakes with my power disc setup will work fine w/out the power assist? (as in spindles, calipers, rotors)

    yep! just gat yourself a new master cyl for a mav (uhhhhh 75 or up i think) and be sure to specify it has MANUAL brakes. all things done right, you can put yourself through the windshield without a lot of effort. my personal opinion is that the power set-up is just a novelty. :2cents:

    swap 4 wheel drum man to disc/drum power!

    Hi Bruce,

    Let me add comments from my real experience with manual brakes on my two Mavericks:

    I have a '73 with 4 wheel drum (non-power) and a '76 (to become my parts car) with front discs/rear drums (non-power).

    The brakes on the '76 with front discs are so much better than those on the '73 (all drums) that I have given up the idea that I need power brakes. The front discs on the '76 engage smoothly and firmly. The '76 also stops very straight with no fear of losing control - unlike the 4 drums '73 - in panic situations.

    As I have alluded to earlier, my plan was to find a Mav or Granada with power and front discs and do a swap onto my '73. Since finding this '76 with non-power discs, I am sure I will be very happy with non-power brakes.

    In addition to swapping from drum spindles to disc spindles, I am pretty sure you need to change out the master cylinder and the brake line distribution block (I know that's not the correct term, but the correct term is escaping me right now).

    I hope it works out for you!

    Regards,
    BaldEagleMav

    ok...here is my q for the brakes...

    i know where there is a mercury monarch with 5 lugs all around....front discs...i am sure that since that is about the same as the granada it iwll work...

    can i take their power brakes stuff and put it in my non powered car and not add the power in my car...but still use the power brakes stuff?

    i hope the question makes sense...i almost lost myself..

    thanks

    OK, you DID lose me, but I will try to answer to the best of my ability.

    Yes, a Mercury Monarch and Ford Granada are the same car.

    Yes, the discs & power stuff will bolt onto a Maverick/Comet.

    I am pretty sure the master cylinder (m/c) for a non-power system is different than for a power system, so you would need to use the m/c which is correct for what you want to do.

    I am also pretty sure that the pedal assembly (under the dash) for a power system is different than for a non-power system, so if you are going from non-power to power, there will be some minor fabrication required.

    I hope this adds clarity and not confusion.

    Regards,

    well let me try to explan better...

    1. my mav is 9inch drum all around..
    2. the monarch has friont disks..and the rear end i got from a granada is 10 drum rear
    3. monarch is power brakes
    4. i dont want powered brakes..


    can i put the power brakes stuff on my maverick and just not hook up the power and will the power brakes work with no power...or do i have to find non power brakes to put in my car... i know i need to change the m/c, and the one i have in there is a newer non power brakes m/c. i can change it out no biggy..

    just curious if i can take power brakes and make them non power brakes for my car...

    is it as simple as not putting on the power booster and no vauum lines... and getting a non power brakes m/c and hooking it up...?

    i am talking way to much,....sorry

    stmanser; you can put the rotors, calipers, tie rod ends, and all the hardware. When you get your new master cylinder, order one for a disc/drum car. As far as the rear, if you have an 8" rear end, get all the hardware from the donor car, and it should work with no problems. If you have a 7.5" rear, get the 8" from the donor car and put on the 5lug wheels. It is an easy swap, and well worth the effort in safety. Good luck!

    i have the 8inch rear end already...i think it is from a 78 granada....at least thats what the junkyard guy said...and the identitag on it says so as well.... but it has the vibration dampner on the bottom of it....thats what threw me off...

    i just have to fix it up....the brakes sounds pretty simply to change over and the monarch i am referring to has not moved in 1-2 years.....i have tried knocking on the door there and nobody ever answers....it is near a business that looks shut down.... i figured the car would be worth about $500 or so...but you never know....

    i suppose if i get the entire car, getting it home and stripped will be easy...the hard part will be disposing of the NON rolling chassis....LOL...

    Ok,

    I want to do a non-power disc/drum setup on the '71, you've convinced me.

    I will need the following to complete this swap?
    1. Discs, calipers, spindles from my '77 with power disc/drum
    2. A new master cylinder for a 74+ MANUAL brake car
    3. Possible modification to the brake pedal?

    Just want to clarify so I get all my parts together.
