Re: DIY Disc Brake Conversion
Usually not, the inner part of the wheel has to have a different profile to clear the calipers, I found that out on mine, 59 wheels would not work with 74 front hubs and calipers.

Re: DIY Disc Brake Conversion
Does anyone have any updates for the disc brakes? I'm thinking about getting the brackets that Mike got from ebay. I need to get moving on my truck in order to meet my May goal of being on the road.
Also, has anyone found the kingpins with the needle bearings for the 3/4 ton truck? I have found them for the 1/2 ton but not the 3/4. Anyone else find the tapered roller bearings for the wheels for a "reasonable" price? Nate |

You don't have to convert to taper wheel bearings. The ball bearing is rated correctly for your truck and the disc addition doesn't change that. As long as they are in good shape leave them. We have been selling 3/4 and one tom kits for a while now. |
Re: DIY Disc Brake Conversion
I have seen kits with the needle bearings in place of the copper sleeves that go into the axle. At least that's how it am interpreting it. I have read that the ball bearings are not good or will not work with the disc brakes and are the ball bearings ok for "today's" highway speeds?

The real issue is making sure the bearing is adjusted properly on a disc, its much more critical that on a drum brake. Angular contact bearing, which are the ball type on the spindle now, are characterized as capable of much higher RPM. Taper roller ( modern spindle) have more thrust radial load capacity, (not radial tire load), and are stiffer that angular contact. that means they can use a smaller bearing and get the same load capacity. With that said he angular contact ball is capable of 100% load in radial or thrust postilions or a combination of 100% Would a angular ball bear be good for road race where there is a lot of thrust load, no. Taper would be better. |
Re: DIY Disc Brake Conversion
Dave,
Thanks for all of the information. It will save me quite a bit of money sticking with the ball bearings. |
Re: DIY Disc Brake Conversion
This may save allot of time or aggravation: I have a 1/2 ton, so I don't need this, but I'm aware many with 3/4 ton would like discs.

Re: DIY Disc Brake Conversion
Anyone have updates for this mod?
I have a question for anyone that can answer: I am fitting my axle under my truck. I put the hub back onto the spindle and tightened the castle nut. I have tons on play in the hub and it will not sit on the spindle properly. What could be making it sloppy? Could the back plate have been holding it on more snug? Thanks Nate |

Re: DIY Disc Brake Conversion
I know this is an old thread but we now have a rear kit in the works soon to be available for 47-59 HO52 HO72 that has slide on drums. We have the test parts in, we will have to tweak them for the final version but it did allow us to do proof of concept. It will work on HO52 HO72 with slide on drums. It allows you to unbolt a rear brake assembly from a 2003 up to about 2010 2500HD and bolt it onto your stock rear end. It keeps the 2003 disc brake, parking brake and rotor without changing rear wheel track. You use your stock hub.
Here are a few pictures. Rear disc swap Rear Disc swap It will be about 3- 4 weeks before its ready. But it is on the top of the work list for us. We do have a front kit and booster kit available now at www.hollisterroad.com |
Re: DIY Disc Brake Conversion
so from what i have read so far there are NO bolt on items i can purchase to do a front disc brake conversion on my 51 3100 6 lug? I see alot of customization (don't have tools to fab up items) but i am looking for something bolt on. Can anyone point me in the right direction? I would like to do a new brake master cylinder as well and i'm sure a proportional brake valve

Re: DIY Disc Brake Conversion

Re: DIY Disc Brake Conversion
Yes i know CCP. PoL. And others. My buddy has a 51 Ford and literally he bought brackets from a gentleman online which came with a full list of parts of what calipers to buy, what rotors to buy, what brake hoses to buy, what master cylinder to buy, with part numbers. It made it simple and very inexpensive. But I have not come up with anything for this.

There are plenty of 6 lug kits out there, as stated earlier in my thread, this conversation is for making an 8 lug conversion which now seems to have a vendor that makes a kit. I attached a photo of what I searched..... |
