Can I go to a regular garage to change brake pads and rotors

unlikely your pads need replacement. ignore the dealer and try to find an honest mechanic. (is that an oxymoron?)
you don't want the pistons to pop out, make sure themech is aware that the brakes are electric.

 

You've been conned - unless, as @Tideland Prius mentioned, you have been driving on the track or extreme mountain driving. At 44,000km I asked about mine - they said they was so little wear that they didn't bother measuring them. TAXIs and UBERs count on at least 100,000 MILES (160,930km).

The thing with mechanics - and worse, the desk guy in service - they see a Petrol Audi, Vauxhaul, BMW etc coming in with 50,000km and think *profit - brake job*. No way with a PRIUS.

 

prius brakes are hydraulically operated, but there is an electric pump that keeps the system under pressure.

for instance, when you open the drivers door, the buzzing you hear is the pump running.

if you were to remove the pads and open the door, the pistons would pop out, creating more work than necessary.
you want an intelligent mechanic who is willing to follow toyota directions, or has past prius experience.

 

no, that's the gist of it. if he is a good mech, he will follow the service manual instructions.

still, i'm not convinced there is anything wrong with your brakes, i hope the mech you found will tell you that, or show you why they need replacement. it is extremely unusual, and toyota has built a sound device into the pads that let you know when they need replacement.

 

Rear brake caliper piston orientation. The brakes must be reassembled with the piston oriented like an "X". Kinda technical, but it's a bit unusual, and if you get it wrong it will bite you. more info in attached.

Also, to play it safe: I would recommend they disconnect the 12 volt neg cable before starting, and reconnect it only when completely reassembled. And test drive the vehicle before using the parking brake, get the rear brakes well seated.

 

mendel, is it the same on gen 4?

 

That diagram says "2016 - 2019 MY Prius [11/2015 - ]"

 

Yeah, in what I cadged:


And at the top of some pages:

 

I still reckon - you won't have to worry about it for many years. The mechanic has tried to rip you off.

 

Just for the record: Toyota says to worry about it every 3 year or 30,000 miles in the States, regardless of pad thickness. Do a pad/shim removal and clean up, caliper pin lube and so on.

 

Maybe - but that wasn't the question - he asked " change front pads and rotors".

Routine servicing would do the caliper pin lubing etc.

 

I'd "suggest" to the dealer that he insert his quote where the sun doesn't shine.

Pads wear out eventually, but without knowing how much pad thickness remains you can't make an informed decision. The pads have wear indicators (squealers) that make a screeching noise when the pads are at minimum thickness. Since you aren't hearing that, they aren't at minimum thickness. If the dealer had told you "your pads are half worn, you might consider servicing them in the near future", that's at least some useful information. Basically, this from your dealer should be enough to convince you not to trust them with any aspect of maintenance. I would be very surprised if your pads are worn out at 30K km. Most Prius owners get in the neighborhood of 100,000 miles on a set of front pads, and generally the rotors are fine at that point.

I'm surprised the dealer didn't quote you on muffler bearings or new Johnson rods as well.

Any competent shop can do pads and rotors. Very basic work, no electronics or fanciness required. On a very few cars, they have an electronic pad indicator on the pads, but any shop can handle that as well. Pads and rotors are one of the most common DIY maintenance items after oil changes.

 

That's an American-spec screw.....

They're metric.
It's "Blinker Fluid" change and 710 cap alignment.
