Disc brake, dropped uprights, and new master cylinder install. Tech Artical

[Plymouthy Adams]

no I am running power R&P steering..the gears could make a bit of difference in the actual turn radius with regard to the original worm gear..Does your uprights have the built in steering stop so to guage how close you are to the original max turn as set by the adjuster on the spindle..This would be the best idicator as to how close you are back to normal...of course equal distance makes for good driving characteristics..lots of cars will turn better in one direction than the other from the factory..known fact..

Hey guys sorry for no updates for a while. I have been working on my latest purchase..... a 63 econoline van. A local guy has owned this for a while now and i have been bugging him for atleast 8 years to sell it to me. Well last weekend he finally did. Will get back on the plymouth soon.

my 1940 dodge currently has the fat man rack and pinion,(caviler) and a master power disc brake set up,,the brake set up was on the car when i bought it,,it uses chevelle 11 inch rotors and big GM calipars,, the coils have been cut to lower the stance,,,

i am wanting to go with the fat man dropped uprights,,and just learned of the EATON coil springs made for this swap,,,altho i dont like haveing the GM bolt pattern up front,,i dont want to have to convert to some one elses disc conversion at this point,,,unless i find some good stock spindles,,

any one know if the master power disc conversion will interfier with the dropped up rights and eaton coils ???

That's a cool van. I've wanted a '60's van for a while. That's wild, with windows on one side and solid panel on the other. Is that common?

Thanks... No not really. Its called a Display Van. Use mostly by telephone and utility companines. Yea is pretty funky. Got the steering box apart right now looking for another. Mine is shot.

I wanted to say, the post by Tank and everyone else was a much needed breath of new life into my 41 plymouth project. Thanks for the pictures.

Any chance of getting an update on your project Tank?? I sent my spindles out to BrakeTech in Charlotte, and they should be back this week. After many attempts of trying to talk to sombody at Plydo, I threw the towel in and called fatman. after fatman takes my credit card info, ect then he tells me they dont have the uprights in stock. I would love to see how your project is progressing...

I got my uprights... Maybe there was a comunication issue at Fatman, but they were supposed to ship them out wed, instead, I got them wed... I am happy. But I was hoping for an update from Tank, and pictures to... It seems the caliper are forward, instead of behind???

[james curl]

If the disc brake adapter mounts to the outside of the spindle as the original brake backing plate did then you should not have the problem of the steering arms hitting the end of the lower A frame before reaching full travel. Whose brake adapter are you using? It is not old daddys because his mounts to the inside side of the spindle?

ok,, glad you got your parts,,,what are you working on???

[Mustang6147]

my 41 Plymouth. I read this article the day I joined this forum. I had my Plymouth in the back garage stored. This post, and these threads, and Tankwilson, and a few others who I dont even know motivated me to the point, that I had it tore down, and parts sent out by 4pm.

Now I am in the home stretch or reassemebly. I found some rotted parts, and the hotrod gods in the sky were smiling down, I found all the parts, and ordered everythiong that eve.

I have belonged to other forums, and when somebody takls about there car discipline is issued for thread hijacking... I never understood the concepts of multiple same topic threads, this forum doesnt appear to be that. I would post pictures if I can, or it is OK to do...

This $$ was earmarked for drage racing this year, and some updated chassis work on my mustang. Looks like that aint happnen. My girl is very happy I am doing this update though.

I will try to attach 2 pics

I simply bought the stock springs. The drop uprights should get a nice raked look to it.

I put the tires on to see how it would look. It seems cool. I did not have to counter sink the bolts in the steering arms though, as FatMan stated. I did trim the arms down, but now I wonder if I had to do that also...

[fstfish66]

wondering why you didnt have to counter sink the steerring arms ??? what are you running for front brakes?? are you lowering the rear of the car also ?? and what steering are you useing??

I am using FatMan dropped uprights. I sent the spindles out to Brake Tech Solutions in Charlotte. I trimmed down the meat on the steering arms, I may not have even had to do that. ??? I called FatMan to see if I was missing something, and they said no. But they never tried there kit with the brakes I am using. I had to bend down the right side arm (straight one) But the reason FatMan gave to me for putting both tie rod ends in from the bottom, is the reason why I want to leave them alone??? I am thinking there thoughts were on a steering system using an idler arm. I have a bone stock front end. I have 11 inch rotors, calipers mounted toward the rear 5on 4-3/4 bolt pattern.

[james curl]

Whose brake adapter and kit are you using? Does the adapter fit on the wheel side of the spindle? You have to modify the steering arms when your adapter fits on the back side of the spindle as it moves the arms 3/8" in toward the dropped uprights and the long bolt will hit the dropped upright before full travel can be achieved.

I hate to repost everything... But in a nut shell. Brake Tech Solutions brakes conversion kit. The only mod to the steering arms are I took some meat off the rear bolt. No counter sinking... I dought I had to take anything off the rear bolt. I bent the right side arm down... That is it. This was super easy thus far, but I am having master cylinder issues, trying to get the dual MC converted. I need a bracket. Does anyone know who makes one, without spending the mortgage on an ECI setup???

[Mustang6147]

Here is a clearance picture...

[james curl]

I am sorry that I asked but I did not realize that Brake Tech Solutions made the brake conversion kit. You stated that you had taken your spindles there, it could have been to thread the mounting holes or for machine work on the spindle itself. I have never seen any ads from them that I know of so did not know that they made an adapter kit.

[Mustang6147]

This thread by Tank, and reading everybodies input was a breath of much needed new life in my ongoing project. Brake tech solutions does alot with muscle car upgrades, and has quite the facility. Pat the tech guy was very helpful, and kept me up to date with progress. I stumbled on them, and got lucky.

I need to figure out which direction I am going with a Master Cylinder now...

If I fab a bracket for a regular Master Cylinder, will the throw , or peddle free play not allow it to work properly?

[james curl]

You will need to extend the actuating arm to get more travel at the mastercylinder. It appears that the dual mastercylinders have a longer stroke than the single one does. I mad a mastercylinder mounting bracket for my 48 P 15 and installed a Chevell disc drum mastercylinder and it always required a quick pump to get the pedal higher so that I felt comfortable with it. I bought the ECI kit and am disappointed in the way that the extension is handled. It moves the brake pedal inboard by 1/2".
