Re: D60 Front Brake Upgrade
Nice tech... I am amazed that someone asked for your files though. I've been looking at those calipers for years.

Re: D60 Front Brake Upgrade
I got the brackets back from the powder coaters today. I'll take pics tomorrow. One of the holes on the knuckle was helicoiled and needs to be redone. I also want to replace the nuts that hold the spindle to the knuckle... I also picked up some new kingpin cap gaskets... If everything goes smoothly, I hope to have it assembled this weekend... And I'll have a 4" steering block to sell...

3. Put an H2 wheel on and measure that. Mine are almost a HALF inch thick at the flange. |
Re: D60 Front Brake Upgrade
Im building a D60 Axle almost from scratch as they dont produce what I am looking for. Like you, I don't like the brakes origionally used on the D60. So I like your thread and progress. My idea is similar to yours in that I was using the factory 2003 Chevy 2500HD brakes since they are already installed on my truck. Since reading this thread I liked the size difference of the Dodge rotor only for one reason. I installed a tone ring on my hubs similar to what Danatrac did. My Chevy rotors have more room than the D60 rotors but it was tight. The dodge Rotors will give plenty of room to mount the sensors. Anyway here is my thoughts/issues with the brackets. Im not sold on using 5/16 plate for the brackets. Even the 3/8 is somewhat iffy IMO. I havent ruled it out yet just a concern as Im driving this on the road as much as the dirt. Also I am having issues with the Lug bolts. I found a Dorman Bolt you may want to look into the 610-215. It looks good in that the rotor holes are very snug to the bolt. Probably the best we can find that is already produced. It may need a couple thousandths taken off the shoulder area but I will see. First I need a lug nut to ensure it will work in my wheel. Good luck with getting this finished.

If I need to upgrade the bracket material, there is an option. Solid Axle makes a new hub that has .33x further offset, so the brackets could be made out of 3/8" or probably 1/2". I just wasnt going to buy new hubs because mine were still usable. If I have issues down the road, I can always take it to the next level. As far as using 5/16 plate, my though was there isn't really any lateral force on the bracket, only rotational. The only other option woud be machining a bracket out of billet. It would be alot more expensive but you couldn't beat the cool factor.... |

Look at the flange the backing plate bolts to on a 14B. Or the backing plate itself. |

Re: D60 Front Brake Upgrade
Parts are looking great.
The shear strength of that 5/16" material with the total surface area you have for the brackets is pretty high. I doubt you will have any issues with it, but if needed you can put some gussets on it in critical areas and not have to build the whole bracket out of thicker material. |
Re: D60 Front Brake Upgrade
Just bringing this thread back to the top, as I am very interested in seeing how Rich makes out with all of this. I too feel that the 5/16" thick bracket would be adequate. If someone wanted to make that bracket stronger, but keep the same thickness, a bracket could be cut out of chromoly plate. Just my opinion.

Re: D60 Front Brake Upgrade
I too am very interested, I need to do a brake job and I would rather upgrade. I have a set of 17" rims ready and waiting. Working on rebuilding king pins right now. Also changing out the rusted metal brake lines the old rubber lines. If possible I would actually like to purchase a set of brackets. Might help with the testing since my truck is driven daily. Thanks.

Re: D60 Front Brake Upgrade
Ryanroo, I'm not saying you don't have a point, but most of what's said about chromoly being this or being that is myth (in my opinion) I wouldn't be afraid to use/weld chromoly at all.

Re: D60 Front Brake Upgrade
oh i agree. i am a professional welder though so i feel like its my responsibility to inform the public that improper technique could possibly cause issues. chances are slim, but in an area such as brakes, its not good to invite trouble. really CM is not hard to weld, nor does it weld different. in this application i would temper the part just to be sure i wasnt inviting cracks.

The biggest misconception with chome-moly is people thinking it is going to make a part deflect less vs. a mild steel part of the same dimensions which it will not. They both have the same modulus of elasticity so they both bend the same amount under load. The chrome-moly just has a higher ultimate strength so it will fail at a higher load than mild steel giving you more safety margin. Same goes for titanium. It flexes a lot but fails at a very high load. You have to design with the flexibility in mind. That is why sanctioning bodies allow thinner wall chrome-moly tubing in place of mild steel. They will both end up failing at the same load but the mild steel tubing being thicker is just heavier. It is the primary reason race teams use it. They can lose weight with it. Dragsters have found they can actually use the extra flex of their thinner wall chrome-moly tube chassis to absorb some of the shock off the line allowing them to put more power to the ground off the line. |

Re: D60 Front Brake Upgrade
I am going forward with my conversion project. I picked up a set of 2010 dodge 3500 calipers which crossover to the 2009 parts used from a local reycycler for $5 each which included the abutment and pads with 30k miles. Front u-joints are gone so 35 spline conversion might be on the list. I am planning trying the soild forged hubs (my truck was a dually so I need new hubs) and is powered by a 6BT cummins. I have so many things to repair, king pins, inner axle seals, axle u-joints, bearings. So its going to be quite a project running in parallel with the brake upgrade. Thanks for the great info.

Re: D60 Front Brake Upgrade
I havent updated in a while because I havent accomplish much... just collecting parts for the LQ9/4L80e swap. Its all connected, disc brakes, hydroboost, etc. so it will all be done in one teardown. I hope this will all start at the end of June and take 2 months MAX... we'll see. Once I know it works I'll figure out about cutting more brackets and at what cost...

The banjo bolt on the Dodge calipers are metric, but you can use the stock 3/8 (same as 10mm) banjo fitting, same as stock I believe. I'll probably be getting custom length braided brake lines from www.kore3.com when I get to that point, but I'm not sure yet how much longer they'll need to be.... |
Re: D60 Front Brake Upgrade
Any Updates? Killer tech and awesome build, i cant wait to try this out as well.

Re: D60 Front Brake Upgrade
Getting closer. A few seals and sone paint and I'm ready to assemble the axle...
