Yep GM master.

It is really what works for you. I used the 73 k-frame and suspension with the large rotors on my 72. With the 73-up style swab bar there is plenty of room. I just have my local NAPA make what ever hoses I need.

It was this thing. Looked to be a pretty original un-messed with car. Was a 318 power disc car. I have a pic of the brakes before I removed them but it is trapped in a crashed hard drive. I used the brakes on my green 72 Dart.

I actually my 73 Scamp had rear mounted calipers. Sure looked to be original and don't know why anyone would have changed them on this car. May have been an early built car, I'd have to check the tag. All of my others 73-up had front mounted.

67-72 front mount would interfere with the sway bar.

I have. The brake width is determined by the backing plates, not the axles. 8.25, 8.75 and 9.25 all can use the same brakes.

My buddy just put them on his 72 Cuda road track car but it is still under construction. On my Dart I have 11.75 on the front with the MBM GM disc on the back using a 1.03" manual cylinder. Stops great for me. I don't care for the weight of either setup though.

I'm using the same GM calipers as the OP and had the same problem at first. For me it was a real fight getting the pistons on the calipers adjusted to the exact spot that they needed to be. Talking .003-.005". Once I did then the pedal firmed right up to where it should be.

These are the prototypes of the MBM rear disc. I helped them design the Mopar setup and they gave these to me.

I haven't decided yet. I've done a lot of Wilwoods and have a bunch of their crap in one of my semi trailers so I won't be going out and buying a setup. My friend is building a 72 Cuda road race car and just installed Cass's Viper setup. It's pretty slick. I'll check out the GT500 setup. I'm...

I have the 73-up factory fronts with the 11.75 rotors. MBM rear disc. Will probably be changing to Wilwoods and put this setup on another car. Flaming River 16.1 manual box. Setup for street and road track like yours.

I use later masters such as this one. This one is an 1-1/16" bore. Dr Diff sells a 15/16" bore. I just tee the front lines and an adjustable valve for the rears.

Autozone and all them carry them plus rebuild kits are only a few bucks.

Also Olds Tornado

Yup have them on the 72 Dart. These are actually the prototypes for MBM brakes. I help them fit these for Mopars.

Ya wow, 4 red X's. I wasn't trying to bash ya and thanks for answering my question. Pedal placement is important. I've used different adjustable rods and made or modified my own to get the pedal where I want it. Is your pedal too hard or soft?

Have manual 4 wheel disc on my Dart and love them. Have used manual disc on a few E body builds and loved them too. What don't you like about them?

:thumbsup:

MBM carries the 73-up A/E factory disc setup. 73-78 B spindles are 3/8" taller than the rest.

I'm running a complete 73 A body front suspension with 11.75 rotors and slide calipers. I would rather have the pin ones but I had the brackets sitting on my shelf. I used the shields again cause they were on the shelf. I'm using a master for an 80 Grand Fury 1.03 bore and also have GM rear...

I went to manual in several cars. Big cam with little vacuum is the main reason plus power is not really needed with good disc brakes. Cleaner look too.

Which kit? For factory drum brake spindles? If so what spindles do you have? For 9" or 10" drums? Any pictures of your setup?

Oh okay. that would have small drums. I'd use Wilwoods conversion that fit the 10"-11" drum spindles. You would need to change your spindles. MBM also has the 73-up A/E factory setup with spindles.

A 73 340 car should have factory disc. Whats on there now?

Yes but you'll need the 73-up A-body upper control arms with the big ball joints. B-body UCA's won't work.

If it has a good master then pull it. Push rods can be found, I have several. If it looks bad then just buy a new one.

Yep, grab everything from the spindles out. Master cylinder and port valve too.

11x3 rears only came on Impierials Had had several B/E bodies with 11x3 fronts and 11x2.5 rears including the 71 R/T that's in my shop now.

I have a few sets of 11x2.5 drums and plate with hardware. Get 60.00pr on the plates with hardware.

All manufactures of all makes used different masters with disc than drum. Not just Chrysler. Even cheap base line cars.
