2013 Prius brake noises.

How many miles on her? Have you ever had the brake system serviced? If so, by who? Have you owned this car since it was new?

Noises from the car after shut down are probably normal. The Prius does make some odd sounds that the regular traditional non hybrid vehicle won't create.

If you can, please answer the above questions. The information you have provided is really insufficient to give any type of diagnosis. Remember that what you read online is mostly opinion and part of it facts. Please consider everything from all sources before taking any action. I do realize that this sounds abrupt and blunt, and I do apologize for that. With additional information, other's like myself will be able to help you better.

It would not surprise me if your brake system needs to be serviced. IE: Brake fluid changed, system bled properly using TechStream Software. Pads or shoes needing replacement as well as rotors possibly needing to be turned or replaced.

The Prius brake system is a good system, and generally lasts a long time. But in certain situations it has been found that the system needs to be serviced more often than normally. One thing that really seems to give a lot of Prius users problems is the glide pins in the disc brakes. Over time they do rust up which causes the pads to wear prematurely and damage the rotors. When that happens the brakes will be noisy and not work as well as they should. I am speaking from experience as I had to do work that is NOT normal on the previous 2009 Gen II Prius that I owned.

You might consider having Toyota change the brake fluid and bleed the system. It sounds like you have been staying on top of it from day one. Could be you just got a lemon. It happens sometimes. And of course, not all dealers (stealers) are alike. Some will do more than others. Have you tried a different dealer? I realize you may only have one to choose from.

Based on what you have said so far, I would suggest a fluid change and a thorough bleeding. If the system still makes noise after that, chances are it something (hate to say this) that is something you may have to live with. I am sure you know that the system is radically different from traditional brake systems. It could be any one of a number of things on the car that is acting up. And from what you have said, it has been going on basically since day one, but has gotten worse over time.

Maybe someone else can chime in on this that has more experience. Patrick Wong? Are you out there?

FWIW, there have been folks in the past talking about Gen II Prius brakes making barking noises when driven from high altitudes to low altitudes. Sometimes bleeding will help, sometimes not. I have yet to see a resolution there also.

I hope you can find the problem. I believe you are not the first to experience what you are describing.

I have had a same exact issue soon after it reached 20k miles. I could hear a brake chirping or groaning sound which Toyota kept saying "normal" for Prius model. Brake system got worse and it is building up some sort of pressure from the brake and release the pressure at some point. When it releases, brake will pulsate pretty bad. Since Toyota claims it is "normal" Prius behavior, I kept on driving it until ABS, BRAKE, TRACTION CONTROL warning indicators to lit up. Noise and pulsation is now gone but it takes twice much distance to stop the vehicle.
Toyota bled out the air and it fixed indicator issue but it was just a temporary fix which lasted for a day. During the second visit, I was told that the brake booster and master cylinder replacement is needed at $3,800.
By the way, my Prius is now out of warranty but it has been an ongoing issue while I had a warranty.
Now I am going through Toyota corporate and my case has been elevated to the customer relations manager.
I will post an update once I hear back from them.

 

all the best! since you reported it while under warranty, you should be covered.
