I just want to know if it will work for my application. I have a '71 RoadRunner with manual drum brakes. I'm putting spindles from a '76 A-body with 11.75 rotors and adapters from a R body. I'm not sure if my original master cylinder will work, if not, is this a good choice? My brakes will remain manual. Thanks, Jim

That master cylinder should work as will several others. Provided its for a RWD disk brake equipped mopar car with manual brakes made from '73-on it should work well. The old standby could always be one for a '73-'74 Charger/Road Runner with manual brakes. '70 Duster 470hp 340/T56 Magnum/8 3/4 3.23 Sure-Grip

I have one of Eberg masters on my 65 Coronet and it originally had four bolts holding the master to the firewall, so I needed an adaptor. Youll need a new proportioning valve when you go to disc brakes, as 4 wheel drums doesnt use one. Adjustable prop. valves are inexpensive. I used to care but....... things have changed

Its a heck of alot lighter even with the adaptor. Youll need the adaptor. Getting one from Dr. Diff would be a good option as well. I dont recall if Ebergs "kit" has everything.

You might try your current one since it is still good, just stick a drill bit deep into the brass seat on the side of the MC closest to the firewall & you'll feel the springy residual pressure valve if there's one in there & remove it if there is. The fluid capacity is less but we are on top of this as opposed to the general motoring public who do not check fluid levels as often as we do. Then you'll know & might save yourself some money & if you then want to change to an aluminum one it must have the recess for the manual brake pushrod & rubber retainer, just make sure you get the bore size thats right for YOUR combination THE FIRST TIME & the adapter plate & you're all set. live every 24 hour block of time like it's your last day on earth

OLD318 super stock O Joined: Feb 2004 Posts: 936	If your doing the A-Body disc brake conversion I would not recommend a 1 and 1/32 inch bore master cylinder. I would go with a 1 inch bore or a 15/16" bore (Both bores are available in front disc/rear drum master cylinders from Bendix) Why? The smaller the bore, the higher the output pressure to the calipers. Your front disc brake calipers will require 1000 psi in order to function properly.. Getting that type of pressure from a 1 1/32" bore master cylinder will require a VERY HEAVY FOOT... more than most people are used to or expect. What happends when the pressure is less than 1000 psi at the calipers? Well, the brakes just won't seem to grab as well... your expecting the car to slow down and stop and it won't, you'll have to press your foot harder to get it to do what you want it to do... meaning stop! There is an excellent writeup of this subject on Master Power Brakes website.. I think it is in the FAQ section on master cylinders... Before grabbing spindles from 1 car and E'bergs master cylinder.. I would recommend you read up on this first... Random parts thrown togethe

Do you mean 1 1/8"? They do require a heavy foot. I'm running one on my Duster and will be changing to a smaller bore. The common bore sizes found for replacement a-body master cylinders (Referencing NAPA) are: 15/16" - Power disc/drum 1 1/32" - Manual disc/drums 1 1/8" - (Common on trucks, including manual) The interesting thing is, MP brakes says larger bore MC's are for power brakes, whereas Mopar seems to be opposite.

Some were concerned that it is possible for the push rod to fall out of the master cylinder if the brake pedal is bumped or pulled back too far, (this means no brakes) I guess it actually has happend to some people. Ehrenberg's suggested fix was to silicone the push rod into the master cylinder.

'73-'76 manual brake A-bodies originally used 1 1/32" bore masters. Contact info

I just bought the car back so I am going to add a spacer & "Dogfather" on here was kind enough to sell me a set of semimetallic pads that I will try . live every 24 hour block of time like it's your last day on earth

Someone said you needed a additional prop valve,I used the one in my car,and never added the adjustable one.It stops fine,even at 116 Mph at the track. I'll also bet good money that R.E. never said to use silicone to hold the pushrod in the master cylinder.Using silicone spray to get the rubber retainer seated fully,that I would believe.

In other words the piston in the back was for a power brake setup rather than a manual brake one. this summer I am going to(on the bench ) use some RTV & let it set up & see whats up with this. It does sound hokey(& unsafe ) but I've always(& still do) greatly respected Ebergs knowhow so I am going to cut to the chase & see for myself live every 24 hour block of time like it's your last day on earth

Dot 3 and Dot 5 really arent compatabile, and seals can get "saturated" with dot 3. Should dot 5 be introduced to a dot 3 saturated system, leaks and failures may occur. The equipment I work on uses exclusively Dot 5. Some other techs have put Dot 3 in by mistake. Sometimes thees problem other times, there isnt. Usually I find problem show up from cross contamination a good deal of time later. Flushing a Dot 3 system with alcohol (not the drinkable kind) can produce a clean enough system to run Dot 5. I am in going to run Dot 5 in my 65. All my brake stuff is new. Also going to run it in my hydraulic clutch setup. Doc. I used to care but....... things have changed

Usually I find problem show up from cross contamination a good deal of time later. Flushing a Dot 3 system with alcohol (not the drinkable kind) can produce a clean enough system to run Dot 5. I am in going to run Dot 5 in my 65. All my brake stuff is new. Also going to run it in my hydraulic clutch setup. Doc. Ya, that is what I am going to do... but the price of DOT 5 is CRAZY - like $1 an oz (the best price is at autozone of all places). I have flushed everything out and most of the system is new (front rear lines, M/C, etc) the calipers and wheel cyls are old, but I flushed them with Isopropal & rehoned them and lubed the seals in DOT5. I also blew air through all the old stuff, put Iso in and blew it out as well. Now on the other car I put Rick's M/C on it does sweat all over the place; I could not figure out where, I guess it is the caps. Need to keep an eye on that.

None worked no mater what I did, including months( a few hours at a time) of bleeding, including power bleeding etc...I thought I was the only one with weeping caps! I went to the junk yard and some used ones that worked a bit better. I still dont have decent brakes after putting the iron back on the Duster! I even bought a brake resevoir and added it and still little brakes. Its a gamble every time I hit the road! Kim

If you use the older style rear cylinders you can have problems with getting the system bled. E-Burg wrote about it in Mopar Action a few times. I had a real problem with soft pedal feel in my 74 Swinger that I had installed an aluminum master, untill I installed the rear wheel cylinders out of a late 70s pickup. very solid pedal from that day on and no more rear wheel lock up.
