Brakes making a Squaking noise when it comes to a stop

Take to a different dealer for second option!

 

Are the brake rotors rusty? It is common for the Prius brake rotor discs to develop a thin layer of rust when they get wet and sit for a while. Then they can squeal when the brakes are applied.

SCH-I535

 

So the brakes squeal but they're not rusty. Hmmmm, you sure? Double check the rears. What miles you at? What's the parking brake condition? Does it come off totally and smoothly?

 

Nope. The Prius can brake much sooner than most! and the emergency brake function works a treat too. Had reason to use it on Sunday when a learner driver stopped suddenly. The two or three cars in front of me stopped and me looking in my mirror turned round to find 4 stationary cars. Slammed on the anchors, the emergency brake took over and I stopped faster than I've ever stopped. More worried about the cars behind me.

So yes, a Prius can stop.

If your car is making noises on braking and takes a while to stop then I personally wouldn't drive it until it's been checked out.

You still haven't said what miles you're at.

 

Sounds like a rusty disc/rotor.

I wonder if the inner pad is worn out and is scraping? Or maybe the inner disc is rusted up - more likely on the rears, esp if the car has been sat.

Some owners have managed to get way over 100,000 miles out of their brakes but it depends on how the car is driven. I replaced my pads at 30,000 miles but only because I drive like I stole it.

Your car may need pads replacing, you may have a rusty or warped disc/rotor.

Get a second opinion if you're not sure.

 

I have the similar problem,first it started out squeaking noise when break is depressed halfway at slower speeds.Now its very loud on reverse?

 

Welcome to the mad house

What's your mileage and whats the condition of your brake discs front and rear? Do they have any rust? Is the usual shiny part compromised in any way?

European Prius brakes are different to the US versions in that ours use softer material as apparently we prefer our brakes with more 'bite'. I had to replace my front pads at 30k miles and again at 60k. I also replaced my front discs and rear pads at that time.

So when you hear US members on here say they got 100k miles out of a set of pads, they probably did, but it's unlikely you will. They're not that expensive to replace over here either, though if you're considering DIYing it, you might want to check the correct procedure because of the computers (or something lol).

 

It is impossible to know whether you have a brake problem without physically inspecting the brakes. If you can't inspect them, then you have to find someone you trust to do it. The dealer has inspected them, but you don't trust them so it is either DIY or find another shop. If you don't DIY, look for another dealer or good independent shop that services brakes, not just replaces pads and rotors. By servicing brakes, I mean cleaning and lubricating the brake hardware, which is very important and likely what you need.

 

Is the noise driectly from the rotors or are you hearing the brake assist bellows. prius do ahve a noise under breaking the sound is more a a wooden pole going threw a rubber disk, squeak or much deeper tone, then it abrupts fast. Squeaking breaks are one thing, scraping is another.

 

mileage is 27000k I took it to the dealer today found out that front left disc is building rust.cleaning has been done no more noise

 

Did you get the recall done at the same time? If you did, you'll find that it uses the friction pads more and should be unlikely to rust up as bad as they did.

You'll be due a service shortly. Check the dealers are using the 0w20 oil which is expensive but gives much better economy/mpg's, especially at the top end.

 

I find that my sister's mazda 3 (2006) stopped way better than my 2013 prius. Probably because the Mazda has bigger rotors front and back. Looking at the rotors in the prius, they are puny...but at least larger than a Honda civic's...oh well..

The sister's mazda 3 squeaked when the car was backing up...and it was brand new back then. I think any car is not immune to problems.

 

Recal?i was not aware of it.can you explain Why they recaling for?i heard 0w20 is for winter but 5w30 is recommended for summer

 

Not in the UK it isn't. The 0w20 is fine for UK temps. I found the 5w30 caused hesitation in mainly town use as lots of small journeys and little engine use meant it never warmed the oil up enough. Maybe once the engine gets upto temperature like on motorway the 5w30 would be fine if you really wanted, but I prefer 0w20 as it gives the best economy. When I had 5w30 put in by mistake I couldn't average over 59 mpg - however hard I tried. Once 0w20 was put back in I could get 70+ mpg or more if driven VERY carefully.

The recall is for a major software update to do with regen braking. It appears inverters can blow under hard use (mine did last year at 70k miles) and the update reduces regen and some other issues. If you're not sure if your car has been done or not then check this link;
