    I doubt I'll upgrade to 17" rims. Then I'd need bigger tires which are heavier. Or shorter tires, which I don't want. Plus I'm more comfortable on the trail w/ steel. I've been going out on some sketchy roads.. Roads I maybe shouldn't in a heavy rig like mine.. But I could see sliding sideways off a loose rock and slamming into another rock and cracking aluminum rims... I'm not trying to take risks.. But keep coming across places where the road used to be a slope.. But is now a series of 15" high ledges, so I have to stack rocks to make ramps.

    Everything is a trade-off for these modified rigs.. I don't think there are any easy answers.

    Pics are of the average road I was on for my last trip.

    That is the electronic brake actuator found ATRAC equipped trucks (OR and Pro), it doesn't use a a traditional vacuum system with a booster like the Sequoia system. So no, the Sequoia upgrade will not work with that setup. You need a Tacoma with a vacuum boosted brake system for the Sequoia upgrade.

    Thanks for the info! Guess I have a 2009-21 SOS Sequoia upgrade kit available for purchase. New in box, just been hiding in storage for years. $250 shipped obo. Will probably make a few other posts on it in the proper forums

    my next question would be, with ATRAC being there, is there even any need for an upgrade when installing the rear disk conversion?

    Likely yes. Rear discs use more fluid volume than the stock drums. People report excessive pedal travel (due to needing to move more fluid) without upgrading the MC after going to rear discs. I think the right fix would be using the electronic actuator from an ATRAC equipped 4runner that has rear discs stock, but that would be pricey and I haven't seen anyone that has done it. The part is more expensive than the rear disc swap, and at that point I don't see it as being worth while.

    lol, dang....I may have a whole kit for sale then. It was more of a *want project than a *need, but would've been nice to have matching rear disc's since I've already done the front.

    The rear discs should work, but the brake feel and pedal travel will not be like stock, and not in a good way.

    Great thread Crash, as usual

    I've only read through the first couple pages, but im wondering if you have an opinion on a runner-up rotor that might be cheaper? My steering wheel is starting to get a little shaky when braking and I'm guessing its the rotors. I just started looking at rotors and i cant imagine spending over $200 for a brake job. I'm starting to do a little research and looking for some that may be cheaper but comparable.

    any opinions welcome.

    edit:

    so far summit is showing stoptech at $95

    why are these so much cheaper?

    i see now that they are the non cryo

    Fyi, not sure if this is covered but I have found on 4Runners and Tacoma's, the NAPA Premium line of rotors look to be OEM Advics Rotors. They have the same indented vain profile as OEM and quality, finish, and price appears in line with OEM as well. Good option for folks to maybe avoid shipping fees and support local stores.

    @crashnburn80, thanks a lot for the whole write-up, it was very informative and swayed me to spend money on cryo/TRD set up. I have no complaints about TRD pads braking performance, nor excessive dust ( there is more dust than with stock pads, but still not bad). Actually I'm pretty happy with it, and as much as I would like big brake kit with rear discs, I don't really see it in my future. That being said... I installed my brakes probably about 25K or so miles ago, and looks like they're getting close to be needed to be replaced. To be clear, most of that mileage is my daily driving within Metro NY traffic with a lot of braking. Aaand my Taco is rather heavy, and I'm sporting E rated 33s, so I think my pads are "allowed" to get used up like that.
    Anyways, finally to the point:
    @crashnburn80 and/or anyone who cares to chime in. Since I don't really have any issues with my rotors, no pulsation, and overall they seem to be the good shape, would changing pads only be a good idea? And if so, what steps if any should I take before I slap a new pads on? Would I need to do "break in" procedures as well?

    Thanks in advance, and if I missed the topic being mentioned previously, please point me in the right direction

    Most shops will not resurface a slotted rotor like the StopTech slotted rotors, so only changing the pads is really the only option. If the rotors are in good shape there is no issue with not changing them out or resurfacing them, so just installing new pads is ok.

    No special steps are required for just a pad change, you will need to perform the break in procedures again though. Failure to do so can result in deposits on the rotor, which will cause pulsing and require your rotors to be resurfaced or replaced. Remember to avoid keeping a hot pad on a stopped rotor during the break-in period. I alway use my parking brake to hold the truck at a stop if needed rather than leaving the brakes engaged during the break in period.

    Would it make sense to scuff the rotors with sand paper or random/orbital sander? (my FIL suggested that a while ago, and it just crossed my mind)

    Edit - - - after looking into it a little further, it doesn't really seem like a good idea

    Has anyone had experiences with installing stoptech calipers on a 3rd gen with crawl control and 16" oem 2020 trd pro rims?


    I want to keep my truck rims and tires but idk if the stoptech 16" 232 6 piston calipers will fit by what i am reading on here please someone clarify? Thx

    So, the TRD pads are on national backorder and I need to order something to change my brakes for a trip next week. I am thinking Hawk performance ceramic..or whatever else I can get fairly quickly. Any opinions?

    The TRD pads supposedly use the same compound as StopTech Sport pads. Having the TRDs and the StopTech Sport in BBK I can say the properties are remarkably similar, so I’d suggest the StopTech Sport pads.

    I went with PowerStop carbon-ceramic pads for their ratings…working great with the stop tech cryo slotted rotors

    Do these rotors etc work for both front and rear? I have 2016 SR5 Dbl Cab 4x4 LB. Thanks great post/info!
