| I am restoring a 61 Chrysler New Yorker. I am converting to front disc brakes. I want to eliminate the stock oval brake booster and install a duel master cylinder mounted on a later year booster and not under the booster as it currently is. Has anyone done this and is willing to share what parts are required to do this. I am sure some sort of adapter will be required to mount the new booster. |

Location: Netherlands | I've recently converted my '62 NewYorker Wagon over to discs. Selfmade conversion with '73 Chrysler rotors.
But the car already had the KelseyHayes inline booster and master cylinder, so can't help you there I think. I do think you'll be better off with what they call a Dual-action booster, as used in the later models. Works better than the earlier models.
I've mounted a MC from a Voyager in place of the original one. Haven't driven the wagon much since the conversion yet so can't share how it works on the street.
On my '65 300 convertible I've also got a discbrake system and although the car brakes just fine and safe with it's stock KelseyHayes booster, it really could use a better 'bigger' booster at times when more firm stops are done.

Location: Slidell La. | Ive bee told that A body disc setups work on just about everything . Don t know anyone who has used this setup . On my 59 Plymouth , I used AAJ disc conversion , it uses their bracket , Chevy calipers , If I remember correctly , I think Aspen rotors , ajustable valve and I used 74 Dart m/c and booster . I bought the brackets lke for 200-250 , can t remember exactly and with the purchase of the brackets he gives you a parts list that you can buy locally , to save on shipping . I love my disc brakes . Good people to deal with , will take the time to answer your questions . Website is http://www.aajbrakes.com/
There are other opinions of the kit on this site , like I said , I love mine . It contains easy of the shelf parts shoud you be out of town and need to do a roadside repair. And last thing to mention , they are not high performance , they are regular duty disc.

Location: Victoria, BC, on Vancouver Island, Canada | Duane, the 1962 Chrysler uses a more modern type of in line booster and master cylinder. The 62 Chrysler firewall etc. is identical to the 61 Chrysler . I have seen a complete 1962 setup installed on a 1961 Chrysler. You would need to have the complete brake pedal linkage, booster, and bracket to do the conversion. Big-M Auto, a member of this site may be able to supply the setup. I put a set of disks on my former 1962 Chrysler 300 with a late model Mopar dual master cylinder which bolted right onto the booster. See the Photo at this link. http://forwardlook.net/forums/photos/show-album.asp?albumid=233&pho... This is an AAJ Brake conversion setup.
Having said that. I now have a 1960 Chrysler with a disk brake setup and have a dual reservoir master cyl. mounted under the booster. This is also an AAJ Brake kit but the Chrysler master cyls are too tall too mount under the booster. AAJ specs a mid 70s GM master cyl. of 1.25" bore for this job and makes a mounting adapter for it. See photo here http://forwardlook.net/forums/photos/show-album.asp?albumid=284&pho...

| I use 74 dart master cylinders on the conversions I do. Bolt right in. The later mopar spindles are an easy change and easy to get replacement parts for.
The adapter plates use spacers and bushings on other conversions. |

Location: Arvada, Colorado (NW Denver Metro Area) | Tucky man! I think it was you I bought the disc brake spindles off of (on Ebay) two years ago for my 59 plymouth. Just getting around to doing the conversion in a month or two after my shoulder heals up. I may have misplaced the sheet of paper where you said what calipers to buy.
Ebay name: katiejackQ
Hopefully it was you or I just babbled on a bit.... |

Location: Arvada, Colorado (NW Denver Metro Area) | Tuckyman (David) The 74 Dart M/C you use... Is it the Drum style or Disc brake style? Power or Manual? Inquiring minds want to know...or at least I do. That way I can ask for the specific one at an autoparts store or find one a salvage yard.
thanks! |

For the people changing spindles for a disc brake swap:
What spindles are you using and what do you have to do to them to get them to fit correctly?
im using 88 5th ave spindles.. i see lots of people here saying to buy pre made kits that use the stock spindle... but i just dont have the coin for all that...
2 spindle rotor calipers combo's from pull-a-part 40 each
turning rotors from junkyard that were luckly in spec 30
autozone parts (reman calipers, hoses, hardward, dust caps, seals, dart master cyl, etc) 120
right there im sitting at 230... all i have to do now is plumb the car and replace the rear brake hose
i know ill get bashed for using spindles that reqire some mods to the steering stops and tie rods.. and ill lose some turning circle.. but i think it beats throwing 250 or so at the orginal drum brakes
im actually doing the swap right now.. i have collected all the parts and i have one spindle on the car now
one added thing ive read on here that the m body swap will not fit 14 wheels.. that is INCORRECT.. my stock 14inch 1960 plymouth wheels fit on the 88 fifth ave no problem

Location: Blythewood, SC | What modifications did you have to do to the steering stops and the tie rods? Austin Swanger had some sort of kit on his car that destroyed the castor and turning radius. He never could get it to align. I think it used A body spindles. |

Location: WHEELING,WV.>>>HOME OF WWVA | this aspen spindle swap isn't rocket science ! the spindle , dressed out sets in as a direct bolt up . the only mods that need addressed , are the steering stop , a simple trim with a wafer wheel and 1/4 in off both the inner and outer tie rods and both ends of the adjusting sleeve to match the ends . when you try to bring the upper and lower ball joints into the spindle , you may have to take a few turns off the torsion bar for each side giving a little slack--------------------------------------------being i have two darts , i've deemed it time to cut back on expenses and this KIT is my way to go for now on big red . bertha already has a set of aaj's . do i trust the aspen spindles ? 110 % !----------------------------------------------------------------when walking into a situation like this , most people are sceptical and try to over think the issue ! ! !-----face value some times works well----------------------------------------------------------------later |

| dont use the 88 fifth ave calipers they use a funky brake hose that attaches on the bottom... 78 aspen attaches at the top giving you more slack and donest use the 90 degress fitting on the line side |

Location: South Easton & Cape Cod, MA | We bought a complete running '85 Dodge Diplomat for a donor for Jane's '57 6cyl. Savoy.
So far it has donated the LA 318 engine, frame motor mounts, trans mount, rear axel, wheels & tires.
Next up are the front disc brakes. Since the '57 tie rods have to be cut, how about using the tie rods from the Diplomat also? |

Couldn't get them to work. I used spindles off a '77 New Yorker, they were further apart, but not a far as the OEM spindles. |

Location: WHEELING,WV.>>>HOME OF WWVA | the diff between the oem spindles and the aspen is one inch , no matter how you figure it's still only one inch difference . if using the aspen setup take some tension off the both sides torsion bars . which will allow more narrowing of the distance between arms----------------------------------------------------later |
