    The dealership told me I need new front pads and rotors. I've got no problem with the pads but I question the rotors. What is the minimum thickness that would trigger replacement, assuming there are no vibrations or shimmies?

    Due to Regen of brakes, the issue is often lack of use, not wear. I had a Prius fail inspection for bad brakes recently. My solution was to take it to a country road and stop from 70 several times in neutral so the Regen was off . It passed -

    Nowadays, it's usually best to replace both pads and rotors at the same time. It used to be that the rotors were thick enough to be resurfaced 1-3 times before needing to be replaced. But today, automakers have thinned the rotors enough that it isn't really possible to do that reliably. After resurfacing, a rotor might fail spec or just barely meet it. And if it just barely meets minimum spec, it also means it will be below spec long before the next pad job. Plus, there aren't that many places that bother to do rotor resurfacing anymore; almost certainly no dealers. Besides the other stuff, the labor to resurface a set of old rotors amounts to the same cost as a set of new ones.

    BTW, a pad slap(changing pads without replacing or resurfacing the rotors) is not good practice. Over time, sand and other particles get between the pad and rotor and wear grooves into the rotor. When you put on a new pad, you now have a flat surface against a grooved one. All of those grooves reduce the contact area and lower braking ability. That's why making the old rotors flat again or getting new ones is important. You want maximum contact area to give maximum braking.



    Although I have to ask how many miles you've put on in three years? I just took my 2023 Limited in for it's three year service(I do my own maintenance, so I like to take it in once a year for a thorough inspection - not the "free" multipoint ones where the techs barely look at it because they're being paid peanuts for it if at all). After 36k miles, I still have 7mm all the way around. At that rate, I should have around another 20k miles left. I even wonder if they accurately measured them because I think another dealership had them at 9-10mm less than 5k miles ago. In any case, most hybrids should get at least 5-8 years/50k-80k miles(often much more) from their pads depending on usage. Replacing at three years seems odd unless you do a ton of hard stopping. If a dealership told me I needed new pads at anything less than 50k, I'd probably demand they prove it to me with a ruler that the pads are under 2mm.

    3mm = time to start planning (or change them now if about to go on a long trip)
    2mm = you're pushing it close (change them now if convenient)
    1mm = DO IT NOW

    BTW, here's the parts list for an LE AWD with prices. A basic brake job is not that hard. Get a quote from the dealer to see how much they want and compare it to the prices I give for parts. You may decide to do it yourself, or at least buy the parts yourself and have a non-dealership shop do the work for you.

    I'm giving four prices for every part. The first price is full MSRP. This is what your dealership will likely charge for the part. The second price is from dealerships I've found that have the lowest typical price for the exact same part. The third price is the current price from those dealerships because of a 15% off Memorial Day sale that's going on until Tues or Weds. The final price is a 25% off sale that happens on Black Friday nationwide as well as occasionally throughout the year at Southeast Toyota dealerships(AL, FL, GA, NC, SC).

    Front:
    $107.26 - $74.15 - $63.03 - $55.62 - 04465-16130 - Pads
    $104.28 - $72.09 - $61.28 - $54.07 - 43512-33150 - Rotor (need 2)
    $ 46.39 -- $32.07 - $27.26 - $24.06 - 04945-33300 - Shims (can reuse old ones if they're in great condition)
    $ 28.76 -- $19.88 - $16.90 - $14.91 - 04947-47030 - Clips (can reuse old ones if they're in great condition)

    So a front kit could cost you as little as $163.76 if you waited for a 25% off sale and only got the pads and rotors. If I had to buy today, I'd go $229.75 and get the pads, rotors, shims, and clips using the current 15% off sale.


    Rear:
    $79.27 - $55.07 - $46.81 - $41.31 - 04466-42080 - Pads
    $98.45 - $68.07 - $57.86 - $51.06 - 42431-78010 - Rotor (need 2)
    $46.89 - $32.42 - $27.56 - $24.32 - 04946-02120 - Shims (can reuse old ones if they're in great condition)
    $28.76 - $19.88 - $16.90 - $14.91 - 04947-47030 - Clips (can reuse old ones if they're in great condition)


    These parts are only guaranteed to be accurate for the AWD Prius and the Prius Prime/PHV. The FWD Prius uses some different parts and I don't have those part numbers handy. I'll search for them if anybody wants them.

    For regular sales, I typically use these two dealerships:
    autoparts.premierautoplex.com (Premier Toyota - North Platte, NE)
    autoparts.lewistoyota.com (Lewis Toyota - Topeka, KS)

    Those are the ones closest to me that also have the max discounts. You might be able to find ones closer to you that give the same discounts. But try not to choose one from your home state so you don't have to pay sales tax. (Unless you want to.)

    For Southeast Toyota dealerships, I've made this preliminary list of dealerships that seem to have the same discounts as the two above. I haven't bought from any of them yet, so I can't speak for their service. They're mostly Florida dealerships because I set my search radius at Miami so I would get only SET dealerships and not a mix of SET and regular ones. I stopped at 9 because I figured that would be enough of a list if I ever decide to buy from an SET.
