    Pulled the trigger on the Rotors, they should show up Saturday, I just want to confirm the TRD brake pads that fit the third gen are the PTR09-89111? Thank you again for a great thread, really looking forward to getting these put on!

    Go Hawks!
    You have to turn the rotors to remove the material. Unfortunately with the slotted rotors it is extremely difficult to find a shop willing to do so, as most all will only do solid rotors. If you cannot find a shop to turn them or a buddy with a lathe, it will require new rotors. Sucks I realize, which is why proper break in is so important. I'm a bit neurotic breaking in mine, where I stop with the parking brake at the last 1-2mph so the hot pads are never contacting the rotor in a stationary setting until a little while after the break in period is achieved.

    Correct, PTR09-89111 will fit 3rd Gen, even though Toyota's parts catalog says it doesn't. I updated a note in the OP next to the part number for clarification.

    Awesome thanks man! The thread has gotten pretty deep so I appreciate the answer so quick.

    How did this work out? Noticeable difference?
    Or should we assume the lack of update means you've slid off the road due to brake failure and crashed and died?

    Got the kit installed last night, fairly simple install. This thread, a couple of YouTube videos and two beers made it easy. I was able to do the 10 hard stop break in procedure for the pads. After letting them cool and giving them a good couple of tests, there is a noticeable difference in braking. Delivered to my door I paid $324 for everything, dealer quote for just new pads was $343, total no brainer.

    Thanks @crashnburn80 for such a great thread!

    Finally had chance to break in the TRD pads and find cell coverage. To recap for everyone, we installed stainless steel brake lines in the front with stop tech slotted rotors, and TRD brake pads. Total cost including installation for the rotors was about $500. I did install the brake pads themselves, first time for me. It was super easy.

    My overall impression is that breaking feel is a bit more firm and stopping distance has been improved slightly. However our primary goal is improving breaking reliability going down steep mountain passes with our extra heavy weight. I believe, that has been achieved. I would do this again.

    Heading out on our cross country drive from Oregon to South Carolina, then shipping the truck to England in five weeks to begin our RTW trip. Starting to get real!

    Hi, Thanks for the update!
    I just got back from 2 weeks in Colorado and Utah. Amazing time. Little Tacoma got me down some great trails I couldn't have accessed in a larger vehicle. Although it did struggle in the mountains at high altitude on the highways.. I had to almost floor it to maintain 40mph going downhill! heh.. No issues at lower altitudes, though.
    RTW trip? Wow!

    Sorry for bit of OT..
    I'll be getting new brakes before my next trip.. I did get more used to them over this trip.. But better is better.

    The small size is what I love about the Tacoma. We have now arrived driven from Oregon to North Carolina and yes, the high altitudes in Colorado tax the truck. I limit it to 3,500 RPM in fourth gear doing 46 mph at times. But it works. I did check the temperature of our front brakes after coming down steep Colorado and North Carolina passes and both times the wheels were just warm with zero brake fade, happy for that!

    I forget, do you have the manual transmission?

    I'd say you have three brake options besides making double sure your existing brakes are working normally. Option one is to spend about $500 and do what I did and put on stop tech rotors that are the same size as OEM and TRD brake pads, while at it I would do the stainless steel brake lines. Option 2 is what @RyanDCLB did and upgrade to a larger diameter rotor and TRD brake pads, I think that would cost about $2,000. Option three would be to install rear disc brakes I'm guessing that's about $2,000 as well.

    Good luck!

    It's automatic transmission. I am still able to down shift when going down hill, though. So far I haven't been on any really steep passes, so engine braking w/ occasional taps of the brakes gets me down hill.. At least while on regular roads. Off road (by that I mean forest/blm roads) are a different story.. Some of those are scary steep! I had to do a lot of road building last week in some canyons on BLM land.. The slopes were turning into cliffs.

    I will likely do what you did. I would go for larger rotors if they'll fit.. But I have aftermarket (cheap steel) 16" rims. I need to do some research about what will fit.

    Edit, heh, I asked if you post about your trips somewhere, but then noticed your signature..
    Back to cleaning the camper...

    Road building? Until I retired this spring I was a forester, which among many duties is laying out forest road, sorry I'm easily diverted.

    Yes, we're on Instagram at 2roguewanderers (mostly photos) and we also have a website at:. www.roguewanderers.com where we do writeups and photos.

    I just meant getting rocks and stacking them to make ramps to get past the badly eroded steep sections. I didn't go off the path or anything like that.

    All I can think about when I'm out is retiring from my computer related job and becoming a forester. Although I know realistically I'm not qualified. Maybe I can volunteer some day.

    There is only 1 BBK to fit 16” wheels and it is just marginally larger than stock. You really need 17s to get a worthwile upgrade. Also steelies are not doing you any favors in the braking dept, you want light weigh aluminum alloys for lower rotating mass paired with the lightest tires possible that meet your service criteria, which C-load is a great fit for many.

    Crash, I’ve gotten so curious about steel weight based on your preference for keeping it light. I have recently been gifted a 5th from a local SD guy. I’ll see if I can get the tire off to get a decent weight on it.

    I believe 2nd Gen steelies are in the low-mid 30s for weight. Something like 32-34lbs IIRC. Compared to the OEM 16” alloys at 23lbs.

    I saw 25 lbs somewhere but nothing trustworthy. I really would like to know how bad it is.

    Definitely not that light for steelies. That is aluminum alloy territory.

    @wicked1, if you're considering buying 17" rims just realize that at least some of the lightest rims like FN for example, have a load rating of only 2,000 lbs☹️. When loaded up with water, food, etc our rear axle is 4,200 lbs. I went with an American Racing wheel, AR 172 that has a weight capacity of 2,800 lbs and weighs 25 lbs

    The OEM 17” TRD Pro 4Runner SEMA wheels are also a good choice at 25lbs, depending on how large of a tire you are looking at running.
