Does anyone have any experience with this setup.
Mopar 11.25" Rear Disc Brake Kit
View attachment 1715679427
Why do you need such big rear brakes? I have Dr Diff's small rear econo kit brakes, from a 2005 Mustang Cobra I believe, and they match perfectly (front to rear bias) with the 11 3/4" Police Taxi fronts I got from him. No need for any adjustable proportioning valve at all.
Internal drum parking brakes have been my nemesis since the dawn of rear disc brakes.
Why is that?
Not sure... might be the same reason I need 500HP, just sayin..
What are you using up front to match these big rear brakes? Maybe 13" with Viper Calipers or something massive like that?
All the Mopars I have ever owned tend to lock up the rears way before the fronts break loose. I've had to use smaller rear wheel cylinders on the rears to "calm" them down before switching to small rear discs like Dr Diff's Econo rear brake kit in combination with the Mopar Police Taxi front brakes with Firm Feel pads. That combination is nearly perfectly balanced on both My A-Body and E-Body. No additional proportioning valve needed.

Fronts are currently 11.75 Mopar big brake rotors off of a Cordoba, pin type calipers, and a Mopar performance manual dual reservoir master cylinder. Car was an original power disc brake car up front with rear drums, so I am still on the stock metering block.
On Drum in Hat vs integrated into caliper - the drum in hat system has superior hill holding torque due to the wedging action and physical size of the shoes vs the small brake pads.
355,000 miles on my 2007 Ram 1500 with the design you mentioned.They seize up, rust up then Heat up rotor which takes out pads, rotor and sometimes caliper. Also destroys shoes. Then you get a giant groove and cant get rotor off because shoes are caught. Turns a simple job into a nightmare.
A simple brake job turns into replacing the shoes everytime you change pads and rotors. Gets expensive on the 2500 rams
If i used it regularly. Who does that? Maybe it would last.
One other advantage to the drum in hat EB is that the calipers can be a fixed rather than floating calipers without having to use an additional mechanical caliper for the emergency brake. Not something I see anyone doing, but something I wanted to do someday and so it was a deciding factor for me.
I have had far more problems with calipers that have a built in e-brake setup than the drum in hat style. Just seems like I spend an inordinate amount of time trying to get the piston back into the caliper when I do a brake job. Pretty sure most shops don't even entertain the idea of using the existing calipers and always replace them when doing rear brakes on cars with calipers with the e-brake built in.
