W250 D70 rear disc brake swap install - DIY4X.com

Not bad on price at all, and a 1 day install time isn't bad either. I'm not worried about tools, I have just about anything I'll ever need to fix a space shuttle in the service truck and almost as much at home.
Keep us informed how they work and if any problems develop.

I wonder how adaptable this is for us dually guys. Other than wheel studs being bigger, everything I believe is the same? Maybe just drilling out the rotor more?

When I was looking into it for my d350, everybody seemed to say that they wouldnt clear 16" drw wheels.

A quick call to them to verify it will work wouldn't hurt also.

Alright, I'll keep that in mind, my brakes work awesome now, but looks like a nice upgrade down the road.

I didn't see any mention of a different proportion valve for the brakes, did you have to change that, or notice where a different one is needed?

On pavement, I havent had a problem yet - even un-loaded, but I'll have to verify after driving down a dirt or gravel road, and see if the rear end trys to pass the front on hard brake application.

On my setup the rear discs are pretty grabby. After not driving my pickup for about 5 months I came into a corner on a gravel road a little too fast. I stabbed the brakes and next thing I knew, I was facing back the way I came from. About crapped myself once I realized what had happened.

Has anyone came up with a good parking brake set up after their disc brake swap?

What about a Mico lock like used on heavy equipment?

[PToombs]

The Mico is a great thing, I've seen them on equipment for years. Just 1 problem, if it leaks off, there goes the truck. It's supposed to be a temporary use brake, like you set it while you're digging, not actually for a parking brake.

I thought they ran off battery power? Leaving one set would run your battery dead after a while.

I believe the Mico is a mechanical lock, but with a warning signal for when it loses pressure. So the only way it would drain the battery is if it sat with no pressure for a long time.

That might be a newer style, or a different brand. I seem to remember something that used a solenoid to hold the fluid, but I know for sure that most of the Micos were mechanical. Throw the lever and it closes a valve. I have 1 here in the garage I was going to use to hold the front brakes for when I was loading the trailer. I haven't put it in because I haul stuff so rarely that's not worth the time to put it in.

Just to let you all know, I called diy4x about this very thing. He said they were not designed for the dodge duallys but that some of his customers have used them on the dodges. So I ordered a set. I also ordered the calipers and rotors he recommended, as well as the lines used in this thread. To answer everyone's question about thr duallys, my short answer is NO it will not work. But I plan to make it work because I refuse to have drums on the back of my truck. I will ne sure and post up everything that needed to be done to make it work. I am already 2 days in and haven't even finished with the first side. I do know for sure that the 16" wheels will not clear the calipers with this bracket. Grinding will be in their future. I'll keep everyone posted on progress.

While my initial impression of this modification was that it worked, I didn't fully get the benefit until I deleted the RAWL / ABS actuator.

Also note that with a working rear brake circuit, it is definitely in the plans to add a proportioning valve, as the rear brakes stop far sooner than the front now.

I'm still happy with the disc's though.
