    I have 60Kmi on the 2010, and was told by the dealer that I was down to 4 mils of pad. Hard to believe, since almost all of my braking is done via regen. What has the experience of others been? Is this a dealer looking for work or are the pads wearing a lot faster then seems reasonable? Thanks

    My 2011 has 73,000 miles.

    At the 70,000 mile mark, I personally inspected the brakes and measured 5mm on the front pads, and 7mm on the rear pads.

    The front pads start at 11mm, and need replacement by 2-3mm. At this rate, I will need new front pads and rotors by 90-100k.

    Obviously it depends on how hard you brake, how often and speed. But when I went in for my 35K mile maintenance and was talking to the agent, she said at the rate I was going, I'd exceed 100K miles before having to replace the brake pads and maybe even 150K miles. We'll see.

    I recall a taxi driver said his brakes had to be replaced around the 60K mile mark.

    when we sold our '04 with 95,ooo miles last year, the mechanic said the front pads would need replacing soon, but not neccesarily right away.

    Anyone know if changing brakes is an easy DIY? Any different than non-hybrid vehicles?

    ^ Just from what I've been reading, if you just jump in there's a fair chance you'll end up with warning lights on the dash after pad replacement. There's also a chance the system will try to pressurize while you've got a pad off, pushing out a piston. In particular if you open the driver's door.

    There are things that can be done to get a DIY'r through a pad replacement, and a few hardy souls are doing their own I think. Personally I might leave this to the dealership, even though I've done brakes on previous vehicles.

    To the OP, why don't you pull a wheel and visually verify pad thickness? Don't unbolt anything on the caliper, just use a strong light, look through the inspection hole in caliper where you can see both pad edges. If the thickness is as they say, get them on it, what else can you do? It's not a second mortgage, lol.

    I had front pads replaced at 30k miles and front discs at 60k miles. Just replaced the rear pads at 80k (rear discs ok).

    It all depends on your driving. Very heavy start stop and you replace them at 30k miles. A nice steady 100 mile commute and you may never need to replace them upto 150k.

    I've had my Prius for a few months...34k on it now. I've done a lot of brake work on other cars and my experience has been that, while the pads and rotors may be ok still, the whole business needs to be taken apart, cleaned, lubricated, and put back together. Is any of this a consideration on Prius brake systems?

    Sure, it's a conventional brake system. While it may see less use, the same principles apply.

    If you are not very familiar with the non-friction brake systems you will cause an expensive trip to the dealership, even though you think you have limited yourself to the friction brakes.

    Either become VERY informed of the quite complex braking system(s) of the Prius, or limit yourself to pads and rotors.

    Our 2010 needed front pads replaced at 62,000 miles even with very careful braking using regen, to the max. I guess the gen 3 do not have the pad lifetimes of the gen 2 reported here.

    I have 75k miles on my 2010 and when I had my tires rotated recently the brake pads were almost 7mm. They might make it to 150k miles at this rate.

    I'm sure mine were never the same after the recall in 2010. Prior to that there was barely any wear.

    I think they decreased the brake life after the software change in the 2010 recall. Mine certainly had a different feel and my scan gauge indicated that the friction brakes would come on faster than before.

    Just came back from the dealer with the following brake wear report. At 87k, front pad has 30% left and read pad has 40% left. Of course, they also advise to do something while your car is on the bay. They said I should machine the front rotors if I don't replace the pads and rotors now. The estimate that the current set will last till about 96k. Total or the pads and rotors, plus tax, will be close to $1000. I told them since I have only another 10k to go before new components are put in, why should i waste $200 now to surface the front rotors. I may as well invest in a whole new set of components now or wait another 6 months. My own estimate is, according to the service history and my driving habit, the brake will last another 10-20k until the 100k mark.

    It appears the European gen3 has softer brakes than the US versions. Apparently we like sharper brakes with more 'bite' and thus they do wear quicker. Our roads are generally more congested overall than in America and you'll rarely be able to drive any distance without having to brake or ram them on when some muppet pulls out on you.

    My car is just shy of 80,000 miles of which 64,000 were taxi work. I replaced my pads roughly every 30,000 miles and the front discs (with the pads) at 60,000. Yes they were worn - down to 1mm.

    I just had to replace the pads on the rear at 77,000 miles and the discs were ok but I can see them needing replacement before the rear pads wear out next time.

    Our local Toyota dealer replaces brakes on a fixed price basis, which is about £100 front or rear pads inc vat. You might be able to get them cheaper but with the Prius braking system being 'weird' and many UK garages unfamiliar with the car, you might be best staying with Toyota.

    I have 138K on my 2006....

    ...Envoy. ;)

    Why would you have to change your pads out at 60k? Do you deliver the morning paper?
    First....make sure you HAVE to.
    If you've replaced pads before on another vehicle, then you'll know how to check for yourself to see if it's required now. Taking it to the dealer to see if the pads need replacing can be somewhat like throwing your wallet down on the counter afterwards and saying:
    "Well OK, but only charge me what you think I should pay...."

    Goofy (2010 G3) has 55K miles on his brakes, and there's still a lot of pad left on the front.....and I drive it like I stole it.
    If it were MY car instead of a company supplied vehicle, I'd probably swap the pads out myself, after verifying the procedure, and after proving to myself that the pads were worn down enough to justify replacement.
    IIRC, this is done frequently on the G2's by removing the Aux battery or pulling a fuse to prevent the brakes from cycling - and at 60K you shouldn't have to worry about fluid yet.
    If you have to have it done for you, have the dealer or independant mechanic tell you why, and give you a firm quote up front for the labor.
    I cannot and do not believe that this is a dealer-only job.

    JMHO.

    Good Luck!

    *Edit* When I say K, I mean thousands of statute miles which is not to be confused with nautical miles (NM) or those pesky little kilometers (k). :)

    Just to comment on the above: the "K's" are likely Kilometers (Canadian post).

    Yes, K is kilometer. Thanks for clarifying it.
