Brake rotor choice (help me decide)

Hey everyone, thanks for taking the time to read through and share your input! I am looking to replace the front rotors and pads on my 2020 Cherokee TH 2.0T (double piston I just checked, I called 3 dealers and they were all told me 1 piston...). I drive in the mountains every weekend as I live in Colorado - summer is hiking/light off-roading, winter is skiing (a LOT of snow driving). Based on this I am looking for something coated to protect my rotors from rusting like the previous ones did. Beneath are the 3 options I am leaning towards and was wondering if anyone had experience with any of the brands and could help me make a decision!


-------
raybestos E3 Raybestos 781768FZN - Element3 Fusion Coated Disc Brake Rotor
matching E3 pads
-------
R1 concept 2020 Jeep Cherokee Blank Brake Kits
kit includes pads
-------
Power Stop Z17 Evolution Plus GEOMET https://www.summitracing.com/parts/PWR-CRK6538
also includes pads

I appreciate all of your help here! Thanks again.
If you have additional tips or advice with the brakes I'll happily listen as well!

Powerstop here. They've worked great on my 2014 TH. Double check your piston config however. TH's should have the double piston. Do a search in this forum, you'll find lots of information on different pad and rotors that folks have used successfully. Definitely however confirm your pistons as the single piston pads, will not fit a 2 piston (and again, I haven't heard of ANY TH having single pistons)

Rusty rotors are not an issue. They only need to by shiny where they contact the pads.
The REAL problem is the wheel hubs, when they get rusty they crack the tone ring. Then the Cherokee goes into limp home mode.
I have talked to the Jeep dealer near my local ski resort and this is a known problem.
Let me know if you figure out how to GEOMET the hubs.
Since you have a TH I suspect you have 2 piston front calipers. Find your brake code, BRF is single piston, BRG is dual piston.
Personally I have really liked the stock brakes on my TH.
ESC and ABS and traction control and trailer sway control are all programmed to work with the braking characteristics of OEM parts.
If you put on aftermarket parts the programming is not changed to match the new components. May work, may not work, I don't want to be the one to find out.
If your are worried about the brake fluid change to Mopar DOT 4 which is used on SRT vehicles.
I don't know how engine/transmission braking works on a 2020 but it works great on my 2014.

I called my dealer to confirm and they said my 2.0T has a single piston, I’ll double check though. Rust is a concern for me as my original ones (about 44k mi) warped because the cooling fins between the rotor rusted so much air couldn’t pass through to cool them and they warped (honestly 10k miles ago). I’m not fully sure I follow regarding ABS/ESC, ABS is a reactive feature based on slip so the brakes shouldn’t have an impact, and ESC is similar but not for braking.

Everyone says powerstop, but there hasn't been much discussion about the differences between the versions.

I am on a super budget right now (New job growing pains) and it is unfortunately time for brakes. I need to put on something cheap. I don't need an upgrade, just brakes that work as good as oem, but budget friendly and hopefully able to last a while.

Any tips?

How come some dealers still don't know... that ALL... all-wheel-drive Cherokees have dual piston front calipers... Only FWDs have the single front pistons.

Your brake code is BRG, if anybody asks (which implies dual piston fronts). If you see a kit that says HD for heavy duty, those are BRG also (it's a marketing thing).

I bought EBC black slotted rotors. Have had them on for 2 years now and no issues yet. I have a post on here somewhere about it.

If you want ones that won't rust for a while I recommend either the OEM or any compatible ones that say "geomet" coated.

Actually I think I might be the odd man out going with OEM! lol
Coming up on 60k in the TH, and the brakes have always been
perfect. Wife is around 90k and her brakes are also fine. If I can
get almost 100k on OEM, then that sounds like the deal.

I thought there was something weird about the bleeding procedure
that had me put off about doing my own. Thought about getting it
to drive half ass to the dealer, (with all new parts) then having them
do a "brake system flush" that way they could calibrate the computer,
replace the fluid, check on the end line, for the rotary girder, etc... :cool:

Living in W PA we get TONS of road salt, plus calcium chloride “pre-treat” which is highly corrosive. I always use coated rotors. I have a 2007 Ford 500 Limited that I drove 100 mi a day for work, mostly expressway. I installed Powerstop cross-drilled, slotted rotors on it with their premium pads. Would stop on a dime from highway speeds and give a nickel change. Saved my buttons twice in tight situations. Without coated, as you said, the cooling slots plug up and fade your brakes. Stopping, to me, is even more important than going!

My ABS is working, so I guess the brakes really can't brake any harder than they already do. lol :cool:
Probably easier to go preloaded calipers... So is bleeding the brakes the same as an old AMC?
I can do that... lol

I got the powerstops not because everyone says so. I got them as wanted something good quality and price at the time. You could go to an Auto zone near you and get lifetime pads and I think a year warranty on rotors. that's what I used to get but at the time there were no stocked rotors at AZ.
 
#25 ·
Right... but which version of powerstop?
 
#26 ·
Z17 is their cheapest I think, sold as OEM replacement. I don't use them so I'll let others chime in. Seems they've gone up in price (entire Powerstop line) in the last few years.
With some fancy searching, I may have found a good deal on their front/rear Z17 kit, over at Rock Auto : $233.79 for 4 rotors and pads. This is for AWD Cherokees (BRG brakes). The kit code is CRK6541 :

If I searched this correctly, the Z17 line also shows a front kit with part# CRK7414 and rear kit CRK6542 (for AWD Cherokees).
If you buy those at Rock Auto, they come to roughly $239 total (for 4 corners), so just a few bucks more than their hidden complete kit (CRK6541).
