Big Brakes with OE Rotors and OE Brembo 4 piston calipers

This is an idea I had that maybe one of our vendors can pick up an run with. PRO Performance is already half way there with one of their exclusive kits.

You'll end up with 14.1732 inch (360 mm) diameter x 1.2519 inch (31.8 mm) thick rotor with a factory 5x5 (5x126.8 mm) bolt pattern. These rotors come on the Jeep Grand Cherokee with the HEMI. They are readily available from parts stores as well as aftermarket manufacturers with dimples and slots. Use the 2006- 2010 Grand Cherokee SRT8 rotors, these are NOT the SRT8 big brakes of the newest 2011+ Jeep...

(R1 Concept front and rear pictured)



You also get a Brembo produced 4 piston caliper that came on both Dodge/Chrysler vehicles as well as Mercedes-Benz.

Here is cross reference list from RockAuto.com

CHRYSLER 300 (2005 - 2014)
DODGE CHALLENGER (2008 - 2015)
DODGE CHARGER (2006 - 2014)
DODGE MAGNUM (2006 - 2008)
JEEP GRAND CHEROKEE (2006 - 2010)
MERCEDES-BENZ CL600 (2007 - 2014)
MERCEDES-BENZ S550 (2010 - 2013)
MERCEDES-BENZ S600 (2007 - 2013)




Here are the PRO Performance hubs that look to be billet aluminum.

So, do you need some kit parts to make these work? On my C20 to C10 drop spindle front conversion kit, I believe it requires the 1.25" rotors...

It needs a hub with the correct center bore and offset with some custom caliper brackets. It would need a vendor willing to make all the pieces fit. I think PRO Performance is almost there with their hybrid Corvette kit. A company called KORE3 also makes billet hubs that utilizes Corvette brakes. I'll send them a link to this and see if they're interested....

Now these are not for our truck applications, but I'll see if they're interested in coming up with something...

Re: Big Brakes with OE Rotors and OE Brembo 4 piston calipers

If you want to get silly, the 2011+ brakes have front rotors coming in at 380 mm or 14.9606 inches x 34 mm or 1.3385...



And the calipers are the 6 piston Brembo variety

Re: Big Brakes with OE Rotors and OE Brembo 4 piston calipers

I have minimal experience with serious brake upgrades on 4 wheeled vehicles, but have done some on motorcycles. On them, oem "brembo" parts (or similar) don't tend to be the same quality as aftermarket brembo. Not saying they're bad parts though.

I'd be surprised if the stock master works well with that too.

I agree on both, but definitely and upgrade from OE 80's technology and quality... and yes, a new master and adjustable proportioning valve would probably be in order...

I designed and built a big brake upgrade on my 72 K5 with a Dana 60 front axle. I used 2010 Dodge RAM 14" slip on rotors and 4 piston calipers. I did also swap in a rear disc axle and upgraded to hydroboost as well. I was lucky with the OE hub and made it all fit together. Haven't run the package yet but I have a version 2.0 that I'm thinking of that uses new hubs from Spintek with a different offset.

I can laser cut brackets. We can draw up the 2D parts and my son does 3D modeling and design work, so if we had a sketch of what is needed for a bracket, including dimensions, or a bracket we can reverse engineer, that part is easy.

As for hubs, I have a Niece that works at a local CNC shop who could get the hubs done, but again, we would need a dimensional drawing or a hub my son could reverse engineer.

I really need to do some research and figure out a good rear brake setup for my 14FF that'll retain ebrake, not use Caddy calipers that people seem to not like, and not cost outrageous amounts of money.

Re: Big Brakes with OE Rotors and OE Brembo 4 piston calipers

There are a ton of options out there, getting someone to cut up the brackets and sell them is another story. With caliper brackets and custom hubs this package would be as expensive as all the other big brake systems out there.

It depends on how bad people really want something vs. just wishing they might be able to possibly, someday, maybe get it. There will always be some Champagne Tastes on Beer Budgets, as well as daydreaming. This is what stops most capable vendors from actually producing anything that doesn't have a built in demand to justify their costs.

Bottom line... if people who really want this, come together and pool resources and skills to make it happen, it can happen. Outside of a vendor specializing in this type of work, and who has significant, built in, overhead costs to cover, no one person has 100% of what it takes to pull it off... but a group of people with skills and resources and limited or no overhead... can.

Re: Big Brakes with OE Rotors and OE Brembo 4 piston calipers

Has anyone gone any further with this. I am looking at doing something similar, but maybe just using the rotors and running a c5 type caliper. Are there any sources for just the hubs?

KORE3 made them before. I worked w/them years ago developing a C5 based big brake set-up that worked w/your spindles (you modded your own spindles). But, as stated in one of the previous posts, pricing impacts demand so I'm not sure if the set-up is a current inventory type of item.

www.michiganmetalworks.com

They make custom front suspension parts... Someone could get them to make a spindle replacement that uses the factory SRT8 jeep HUB, rotor AND caliper that mates to factory control arms or custom arms set up for bags....

Re: Big Brakes with OE Rotors and OE Brembo 4 piston calipers

Not that I have checked the fit but a 60s Cadillac front hub uses the same wheel bearings as a square. I have one here in the floor, the drum needs to be removed to try it though. Jay

Re: Big Brakes with OE Rotors and OE Brembo 4 piston calipers

I'm in the middle of doing a similar brake upgrade on my truck. CPP Modular spindles, CPP forged aluminum hubs, 2nd Gen CTS-V rotors and calipers, and custom caliper brackets. The parts are at a machine shop now to have caliper brackets made. We'll probably have a few extra sets of brakets made if anyone is interested. You'll need at least 18" wheels, and the hubs are 5x4.75 but othe patterns may be available.

Re: Big Brakes with OE Rotors and OE Brembo 4 piston calipers

I like the concept! Can you post a link of the CPP parts that you used?

AZ Pro Performance has a decent kit for the C10's now. I just wish there were other companies that made brackets to allow the use of calipers and such that a person already had. For instance I have C5, C6 and the "LS Series" Camaro brakes and such already so I just need brackets to bolt the calipers to aftermarket spindles.

Re: Big Brakes with OE Rotors and OE Brembo 4 piston calipers

The reason I thought of the SRT8 parts was the rotor is OE 5x5 bolt pattern. It would be nice to use the sealed bearing too...

http://www.littleshopmfg.com does a lot of custom parts. They may be willing to work with someone to design and build a kit.
