Upgrade brakes

I think it's common knowledge that the Commander brakes suck. I've had 2 of them now and they don't exactly inspire confidence. Heck, the magazines peg it at 140+ feet 60-0.

Anyway, I'm looking for a moderate upgrade to the stock brakes. Probably front and rear - pads, rotors and calipers.

Let me know any other ideas or opinions on this.

Thanks.

I have the same question here as well Bobula. Hopefully, we can get some feedback on what options are out there.

Brake Pads

The better the brake pad the shorter the life of the rotor as the more metalic particles in the pad the faster the rotors wear out.
I understand you wanting to stop faster but don't be shocked if you are replacing rotors more often.

The brakes on ours weren't that bad. I just had to replace pads and rotors at the front. One caliper hung and wore the inner pad down to the backing plate on the left side.

From the factory, these Jeeps got Akebono ceramic pads. If you replace them with those pads or similar, the brakes are as good or better than any truck of similar weight. Have you driven a Suburban or Yukon XL? Or an Expedition or Excursion?

I just replaced our pads (which were crappy aftermarket pads installed by the second owner, and we're the third owner) with Bendix CT3 pads. I also rebuilt the left front caliper myself (new seals, new pistons, new pins and boots, fresh grease in the pin bores). I'm happy with the brakes now, and the Bendix CT3's do seem to be an improvement over what we had.

There are a lot of aftermarket pads which don't perform as well as the stock pads. A high quality ceramic pad (Akebono, Bendix CT3 and Wagner ThermoQuiet all get good reviews) helps braking performance. I even considered Hawk LTS pads, which are probably a bit "grippier" and might stop a bit better, but with more dust and potentially more noise issues. I've used Hawk pads on other vehicles, including a set of LTS pads on a Suburban, and they do offer more braking for less pedal effort.

Flushing the fluid at least every two years is a good thing, too. That keeps the pedal firm.

I'm not a fan of drilled and/or slotted rotors. They wear pads very quickly, and they don't really offer much advantage if you're running good brake pads. If you're running cheap pads, you'd get better bang for your buck with good pads than with drilled and/or slotted rotors.

I just put all new drill/slot PowerSlot rotors on mine with ceramic pads. Braking power is pretty good.

How does the performance compare to stock?

I didn't drive it much prior to the change but they weren't bad as far as I could tell. However, the performance with the new brakes is quite impressive. Everything is new though.

Hey @Flex;

I'm curious, which kit did you order?

I ordered this brake upgrade kit which is waiting for me when I get back to the states;

Power Stop K2220-36 Front & Rear Z36 Truck and Tow Brake Kit;

I used that exact kit with the Z36 pads. I have used them before on a 1999 ram 2500 and a 1989 Mustang convertible. No complaints.

As to the drill/slots, they reduce heat and thus the possibility of warpage. They are also lighter than a solid rotor improving acceleration. I have been using them for many years on 6 different vehicles and have yet to notice any premature wear. I used ceramic pads. Perhaps if a cheap quality semi metallic pad is used, it may result in accelerated wear.

One thing to consider if going to slotted/drilled rotors is the chance of debris such as a small stone getting caught in them. If someone does a fair amount of off-roading, then if a stone gets hung up in the rotor, it will chew a pad up pretty quick as well as possibly starting a crack in the rotor
