    No need to jump off the deep end here.
    Driving is a continuous improvement kind of a skill, there is an optimal way to do everything.

    If you are having repeated issues with this in the same application (this truck towing said trailer) perhaps a bit of change of technique is called for. A need to learn more does not automatically make someone "shitty" at anything.

    Half in fun and half serious: Any drivers other than yourself?
    Wives and youngsters tend to be hard on brakes I have observed... Like cruise control 3/4 the way up the off ramp at 70 and planting the brake pedal hard.
    If you find the friction surface of brake pads cracked (from excessive heat) usually it is a ladies or a kids car it seems. Just observation, no :crapstorm:intended.

    Well adjusted trailer brakes & controller should eliminate most excessive wear when towing.

    For aftermarket pads I have always had good service from Wagner, using the Severe Duty line on my heavier vehicles.
    OEM Toyota parts are fine quality too and generally fairly priced.

    I bought some ac delco brake parts for my el camino, absolute garbage. One of the new rotors was so badly warped it couldn't be cut straight. The supposedly new calipers were rebuilt at least 3 times. My suggestion is to not use ac delco anything.

    It's just my wife and I and she rarely drives our Tacoma, so I'm to blame for any unnecessary brake wear. My commute to work is just shy of 80 kms each way and over 90% highway driving. I sit in the slow lane doing the speed limit and let everyone pass me and merge in front of me and try not to follow traffic too closely. I don't have to drive in every day and over the last 2 years I wasn't able to work for a few stretches that lasted a couple months, so the truck hasn't been driven nearly as much as it normally would.

    Appreciate all of the feedback folks!

    I really just wanted to know if Toyota's OEM brakes were known to wear unevenly.

    Thinking we might just stick with our local Toyota dealership for another brake job. We have lifetime warranty on the pads. We've been satisfied with their service for over 15 years. We're having the trailer brakes checked and bearings done next week. I'll reset the brake controller gain once we get the trailer back. Then, I'll try and improve my driving skills and see how long the latest set of brakes last.

    Don’t take it personal. Every time this topic comes up, there’s always people that place the blame solely on the driver.

    The fact is, it is almost always drive conditions. What most have not realized is your concerns happened after towing.
    This isn’t all that uncommon.

    Anytime you are towing you use more brake and the heat builds. Couple that poorly adjusted rear brakes (we have drums and they need periodic adjustment) and you rely more on the front brakes.

    Then when the fronts get hot, and you come to a complete stop. You are cooking the rotor in one spot. The spot directly under the pad. I try to stop “early” and give myself some room to “creep” when I’ve been on the brakes hard. That way I’m not roasting the rotor in one spot while stopped.

    The brake on the Tacoma are just adequate for truck itself. Put and weight behind the truck and they get sketchy quick.

    As for OEM being known to “warp” or poor quality. No, they are not known for it. Actually the stock rotors are really good for what they are. Pads are nothing fancy.

    Again, don’t let people get to you man.
    Brake problems can happen, and sometimes it is beyond our control. All we can do take a few extra precautions to cut down the chances of brake “failure”. Engine braking(dropping a gear or gears) and more stopping distance helps a lot.

    Like I said in a previous post. Don’t be afraid to get the engine help you brake.
    My engine sees the 3,000+ RPM pretty regularly when towing.

    @Mattedfred I had a similar situation on my ‘06 a few years ago. Bought some Brembo blanks an pads at Canadian Tire. 20k kms later, same problem. I now have Brembo blanks and OEM pads. 45k kms and still braking smooth. The Brembo blanks go on sale often, check for them.

    Hey, thanks for the post. What are Brembo blanks?

    Sorry, blank rotors, no slots.

    I put brembo drilled rotors and repco pads on my supra. They worked very good, really too good, I'd find myself accidentally stopping a couple car lengths too soon. The issues were the first cold stop was sketchy so I'd have to get a little warmed up, second stop was fine. Then the pads didn't last too long. But that could have been me going woohoo, look how good I can stop.

    I've driven a 5 ton truck for work for years, used to. It taught me how to manage brake heat. Now I'm in a crappy ford transit van carrying too much weight with crappy brakes. Again having to manage the amount of heat my brakes generate. Some guys I work with don't know how so they're getting brakes 3 times a year. I've been about a year on the same brakes.

    What I do is brake for 5-10 seconds, a quick release and start braking again, when I can. Lift when I know I'll need to stop soon. The harder you press the pedal, the more heat you're generating. If it's a panic stop you gotta do what you gotta do. The creep technique tnshooter mentioned is good too.

    Another thing that could cause rotors to warp is water. Driving through a deep puddle or washing it when they're hot.

    I do this too, as for whether it actually helps?
    I don’t know for sure. But it can’t hurt.

    I do know heat soaking a single spot on the rotors (hot pads/rotors and stopped) can definitely cause issues.

    I guess it doesn’t hurt that my father has been a OTR Truck Driver for about 25 years.
    I learned to drive like I was driving a big truck.

    Don't overlook a sticking caliper causing the rotor to get too hot. Is the pad wear even all around?

    What's everyone been averaging for front brake rotor life?

    I have never needed to replace the rotors. I just do it when I do pads because “why not?”

    Pads have been averaging about 70-75k miles. That is when I change my rotors.

    Still on OEM factory shoes with 151k on them. They are getting “thin”, but still have some life in them.

    Because of my job, I talk to a few shop owners, and from random conversation, noticed many use Centric brake parts (rotors/pads). Note they have a cheap line which I don't remember the name of, but NOT that one. Many have stated Centric seems to be the most consistent quality wise, with fewer bring-backs, so that's what I've been using for years now.
