Over 400K miles on original Prius Brakes?

    A while back I asked our parts deliver guy how he liked his Prius. He said he's put over 400k on it and loves it. I asked him if he had to change the batteries yet. He said not only has he not changed the batteries, he hasn't changed the brakes.

    Comments?

    That is really hard to believe 400K with out having to change the brakes.

    I asked the head mechanic at my dealer how long I should expect the brakes to last on my Prius. He said because of the regenerative braking, around 70k-80K miles. He then added this remark that the reason for the needed replacement was due to the rotors rusting because of age and the elements, not brake pad wear. So based on that philosophy I should get at least eight to nine years or more from the original pads on my Gen III

    How close is that dealer to the Gulf of Mexico?

    I had 100k on my pads when I traded in my Civic. It doesn't have regenerative brakes, and part of that time was pre-hypermiling so I used them more. I can believe 200k in a Prius, not sure about 400k.

    I am at 125k on my Gen III and at the last dealer oil change they said I had 90% of the brake pads left.

    I've seen write-ups at 100,000 with pad wear detected only with a gauge. No visible wear.

    Approaching 50,000, mine are like new. Use them just a little to keep the rust down.

    The pads on the Prius can last 1 million or more miles and here is how.

    If rust is not an issue like here in CA and you ALWAYS try and stay out of friction braking zone on your display. You would be purely using regen to slow down. The few times you may need friction pads would be for more sudden stops.

    In this way you can drive for the life of the car without changing pads.

    I rarely ever use friction pads with how I drive now.

    Also, I have seen a number of posts on priuschat with people reporting 200k & 300k+ on original pads and rotors.

    There's more to brake maintenance than just replacing spent pads. OTOH, I do think the Prius brakes lead a "sheltered life". Ours still look like you could eat off them, at a mere 32000~ km's.

    The fact that he is the head mechanic at a dealership throws up an immediate huge red flag.:eyebrow: At nearly 70K on my '07 Prius, the pads look nearly the same as they did when they were new...and there is no rust in sight. Sometime ago, Hobbit, who used to be a regular around here, told of a way to deal with the rust issue: Once a week or so, while at a relatively slow speed, put the car in N and gently apply the brakes. In N there is no regen braking so a light application of the friction brakes at the slow speed does an awesome job of cleaning of the rust. With now radio or blower motor running, you can easily tell when the rust is gone and let off the pedal before pads actually make contact.

    Only 70,000 to 80,000 miles? I have 184,000 miles on my Saturn (and 20 years this August), with original brakes, and over half the miles were before I started hypermiling! I'm expecting to never replace the Prius' brakes.

    So far, I've been averaging 150,000 miles on the front pads and 330,000 miles on the back pads of the Aerocivic. Brake pad longevity likely due to the use of hypermiling techniques, mostly rural driving, and the low weight of the vehicle.

    Amazing! How many miles do you have on that AeroCivic now basjoos?

    I went 294k in my 2005 prius before changing front pads. 270k for the rears. Prius totalled at 336k.

    Were you religiously staying in the regen zone and out of the friction breaking area for most of the 336k?

    It wouldn't be all that hard to stay in the regen zone. I've not driven a Prius C (saw one today in Elkhart, IN by the way:cool:), but in my '07, regen happens all the way down to 7 mph and a stop from that speed would be very easy on the friction brakes.

    I have a 2009 Prius. Can someone please explain what the "regen zone" is and how to monitor it?

    I'm not at all familiar with a Gen 2 car like your 2009 , neiman. I'm not even sure if my Gen 3 car shows where the regen-only zone ends and the mechanical braking begins. I want to know , also. I will need to study my manual. Maybe someone here with a Gen 2 car can chime in ?

    Usually at or near the leftmost edge of the HSI range.

    Thanks. I never get that far to the left. Or if I actually DO , I'm watching the road ahead so I don't plow into something ! Sometimes you have to use the brakes. And in the Chicago suburbs , expect the unexpected. You try to create some space in front of you for the inevitable 65-25 MPH that happens on our expressways. At least I try to minimize it to 55-35 MPH if I can. Accelerating to 55 MPH takes a lot of fuel , even in a Prius. It's not something you want to do over and over again.
