Teraflex big brake kit

Am looking to install this on my 2013 JKUR. Do I need the heavy duty master cylinder?

Teraflex representative input would be appreciative. Or some other tech.

I'm no tech, but this is the 2nd Jeep I've run the kit on. I run the factory master, no issues. Braking is much improved.

He might be talking the whole big brake kit and not just the bigger disc with factory caliper kit, it is recommended to run the master with the bigger calipers. But not mandatory.

I have both and it's enough to make 37's howl if you jump on the brakes in a hurry.

What size tires are you running?

With just front Black Magic brake pads, my JKUR with 35s brakes better and faster than it was when stock. That cost $125. Granted, my Jeep was pretty new so I did not need new front rotors. Just another option though I do like the idea of bigger rotors.

I wasn't sure how true replacing the brake lines would better braking. Well I broke a line and running 1 (somebody's trail spare) braided line on the left side. When braking I have a slight pull to the left. This is the side with the new line. Time will tell with new lInes going in soon.

HK ... Is there a special break In procedure with the BM pads ?

There is a break in process. I only did the first half of it and it still works great. Maybe I should complete it.

I went ahead and changed my brake lines as well. That lead to a firmer pedal feel, which is nice. If I need rotors, I'd get Centric- like i did last time. However, Black Magic carries those for just a few dollars more than some random store, so I got them from BM last time. Not needed if your rotors are pretty new though- the stock rotors work just as well.

EDIT- I have also read that adding the bigger Teraflex master results in softer pedal feel.

Not sure if I'd recommend slotted rotors either... They are some noisy bitches when they get dirty.

First of all CONGRAT'S on upgrading your brakes!!!!!
Most just go to larger tires, and wheels, that just add additional circumference and weight, and never even think about, how they have just de-graded their braking capability..........

OP, as to your question, I would call the supplier that I purchased the kit from, and ask them this very important question!

Since this is a safety item, you don't want to second guess, and or make the wrong decision........

Hmm, my last jeep had them and it got muddy, water, you name it, and I never noticed any increase in noise. Haven't taken the new one out yet but I'll try to pay better attention and see.
