Disk brake questions.

First off I started this thread after reading potlucksamys (prolly screwed that up) post about his setup, and he said he didn’t want it to turn into something it wasn’t so out of a desire not to hijack his thread I thought I’d quote and then ask my questions in a new thread. I tried to find more info about this but didn’t.


I know OP found his solution, but I didn't see a few other options listed here. I've found a few places that supply these kits and they're usually very expensive, ie: $2k+/axle. However Boyce Equipment is offering kits at the lowest prices I've seen. I don't know about the quality though there are a few videos on YouTube that reference these kits from people seemingly unconnected to Boyce.

2.5 Ton Front Hub Mount Disc Brake Kit | boyce-equipment (boyceequipment.com)

2.5 Ton Rear Hub Mount Disc Brake Kit | boyce-equipment (boyceequipment.com)

Motor Trend did an article on the Boyce kits in 2019. There wasn't a lot of information, but there were lots of pictures.
I want to do this so badly. I have questions though.[/QUOTE]

Brakes have been something I never really excelled at and am trying to educate myself.

My first question is what would you do with the front brakes?

Next, with the advantage of disc brakes if you have them on both rear axles would you even need brakes on the front axle?

Finally I wonder if that kit comes with the seemingly hard to find brackets or if one would have to have them made.

I’m just sick of the wheel cylinder issues already. I ordered 4 more for the rear and am going to just replace all of them at the same time with the same part from the same shop. Then I’ll get rebuild kits for the ones I take off and that way I have them on hand until I can do those rear axles. Maybe there’ll be a little more consistency.

Front brakes do most of the braking in many situations. I don't think you could get by without them no matter what.
I was wondering because I have not seen any front disc brake conversion kits. Only for the two rear axles.

about 4-5 years ago there was someone who made a full disc brake M-35
and if memory serves me this person used the brakes off of a ford F-700 ?
no and I can’t remember how the hubs were, but it was a slick install.

That would be a lot less expensive I bet.

The deal on those kits is the bracketry to support the caliper, and machining the hub to allow a welded flange to mount the rotor on.

Any good machinist can build those parts to fit whatever caliper/rotor you find that will take the load OK.

I have a Ford F700, and the disc setups on it look just right for using on a deuce.

Jus sayin...but I don't have a 2.5 anymore. I need to do research for my 5-ton, tho.

Do you think the 700 parts would bolt up without too much modification?

A lot of the “monster” truck guys run the 2 1/2 axles ( along with the 5 ton)
and they run disc brakes. I would see about a little research in that area.
my background is aerospace and l am amazed that when there is a problem
most of the time a whole lot of engineering is wasted on reengineering the
the wheel. When the problem has already been solved by the sailboat,
heavy equipment, farming, aviation, hot rod,construction etc. community.
But usually no one ( or department) looks beyond there own area of
expertise.
