Hi folks,
I am working on my TJ, and I have the stock brakes (front and rear disks, pads and calipers, master cylinder etc all new) perfectly tuned.
However, the stopping power with my 31s is OK not more than that, I assume that this is how TJs came out of factory. I am asking myself how that thing was supposed to stop, let's say with TJR on it's 30.5 inch tires with let's say towing anything.
Now, I am installing the Yukon 07 kit with manual hubs, which came with its own rotors. These are special rotors that match the manual hubs.
I am thinking about upgrading brakes, w/o braking the bank.
I would appreciate your opinion on what is a proper brake upgrade for 31s (I run 10.5 width goodrichs on 15 inch wheels) for relatively loaded TJ (hardtop, rear tire carrier bumper, 4.0 engine and front winch with bumper).
The options that I see:
1. Keep the brake rotors that came with Yukon 07 kit and my rear auto zone rotor and BMB (Black Magic ones) pads to it. Cheapest option, but I question the quality of the rotors from both Yukon 07 kit and from Autozone. My concern is that better pads with questionable rotors will not work fine, due to rotors overheating or something.
2. Get proper quality rotors for rear (I can buy them from BMB or somewhere else, as they are standard form), add to them BMB pads, then somehow obtain proper disk rotors for Yukon 07 kit that can work with both manual hubs (seems like I will need them to be widened as the hole is not standard due to different hub) and BMB pads - this should make sure that I am not pairing weak disks with strong pads. This seems to be a mid price option.
3. Go to dual caliper 15inch Big Brake Kit. This is a challenge because somehow it needs to be figured out how to pair the brake upgrade kit with manual hubs kit. It will be an improvement over previous option, but what I am asking myself is whether I am not overkilling this. I don't do anything crazy in the rocks, and my TJ is for traveling to national parks, more like an overlanding thing. If I would do 33s and higher, I would not think twice before switching to Big Brake kit, but on 31s it seems to me a little overkill.


Looking for an advice here.
 
I think BMB pads all around would be more than enough for your 31s and would be the cheapest/simplest option. I have no input on the quality of your current rotors.

You don't need the big brake kit. The pads will be fine and if you would like a spare set of the Yukon rotors, we have a few that we send out for the cost of shipping. If you do wind up with larger tires at some point where you need the bigger brakes, you send us some parts from the hub kit and we make it all play nice together. The only additional charge for that is whatever the machine shop charges to open up the rotor center bore to fit the back of the bearing hub.

Thanks a lot.
