    Those threaded holes may be have one and a half turns of a tap there's no meat there You can blow them out very easily That's why I use them just to put a little tension on the plate spray the Aerokroil In those holes while you have the bolts out then put the bolts back in add a little tension let it run down in between the business job the hub side to side a little bit as in trying to turn it. Had a little more tension a few more taps and usually by then it's starting to come off but yeah you can blow those holes out very quickly if you're not careful.

    @CARSFAN4 (OP) is in Los Angeles, definitely not the salt-belt. Would be good if he could post some pics, see what the rotors look like. Checking them requires a micrometer, and a dial indicator with magnetic base, as long as we're talking tools. Both those items are fairly cheap, maybe $100 USD in total?

    Still, he is doing a tilting-at-windmills diagnosis.

    I haven't had issues with stripping the threaded holes, myself. Maybe more likely in some aftermarket rotor made of papier-mâché?

    But I'm cheating ... I tend to inspect my brakes every time I rotate the tires, so my rotors usually flop right off.

    Hi we have a 2014 Prius c and were having some braking issues like noise squeaking and when it rains and we come to a stop it will grip and come to an abrupt stop no matter how gently we press the pedal. We researched and everything we found said that these are regenerative brakes and will likely last the life of the car. Did you actually see wear on your brake pads, rotors or calipers? If so I would like to know because then we likely need our car put on a lift to check out the depth of wear. My son did hours of research regarding the brake pads because my instinct with cars is that the brakes always need to be done when buying a used car. Thank you for any information you can share on your experience.
    Sincerely Carolyn

    There's a yes part and a no part. Yes, the brakes can last a really really long time if everything stays good. On the other hand, there are little things that can happen (like the 'fitting kit' clips where the pad ears slide getting rusty, or slide pins getting sticky, or a nick or tear in one of the rubber boots there to keep salt water out so stuff doesn't rust), and those little things can cause the brakes to wear right out while you're not looking because you expect them to last really really long.

    In the warranty and maintenance guide there is a routine quick inspection of the brakes at pretty much every service, and a more thorough one every few years. I do my own inspecting, and many times the result is just "yup, ok" and put everything back with no need for any new parts, and every now and then I'll put it back together with just new fitting kits (< $20), or anything else that looked ready at the time.

    Keep up with the inspections and the little things, and you really can go in the ballpark of a couple hundred thousand miles without needing any bigger stuff for the brakes. But overlook the regular inspections, and big stuff can come up faster than you expect.

    (One reason I do my own inspecting is that if you have a shop do it, there's pretty much always an incentive for the shop to say "oh, looks like you need this 'n' this 'n' this.)

    I have a 2014 Toyota Prius C and everything that I have read about these brakes is the first thing to go bad is the caliper bolts which then cause a chain reaction to the pads then the rotor. I encourage you to check out your calipers and calipers bolts to be sure they are moving freely and not sticking. I have read quite of few reply's in this forum. I hope this helps. Have an awesome day on purpose.
