Clicking noise from brakes when reversing. Recording attached

I don't know if you remember, but I had that leaking radiator/hose tread several weeks ago. Here. Anyways, that was fixed with a simple worm gear clamp (when the dealership quoted me over 500$ to fix it).

One other thing which was concerning me which the dealership didn't help with was my brakes. They did a "multi point inspection" and one of "points" were the brakes where they test the brakes and also remove the wheel to check the wear left in the brakes. I pointed out the the service guy that my brakes make a clicking noise when i reverse but he said the technician didnt find anything wrong with the brakes. So I told him to hop into the car so i can make him hear it, but because the dealership was next to the highway, there was too much noise and he couldn't hear anything.

So can you guys please play the mp3 which are in the zip and tell me what you think. As i understand the friction brakes only come into play during slow driving and reverse. The brakingis absolutely fine when i go forward, just when i reverse.

In the Mp3's i was slighly pressing the brakes so it squeeks then i pressed the brakes harder and it makes that cliking/poping noise.

Thanks a lot for the help, and please let me know if you have any further questions.

 

the strange thing is that this noise is coming from both front wheels, so im not sure if somethingis stuck in there. what do you guys think?

 

it only clicks when i apply the brakes and when im reversing. When i reverse without pressing the breaks, there is no noise at all.

 

As I stated above, the noise is coming from the front brakes.

 

If i get a chance this weekend, I will go through HObits brake cleaning tutorial and see if there are any obvious visual problems. Do you guys have any tips on which parts to pay particular attention to?

Thanks

 

Hello. Sorry for the late reply. When the opened everything up... nothing. There were no pebbles, no visibly loose part etc. The thing that confuses me is that there is no noise when i am going forward, only when I reverse slowly and apply the breaks.

When I press the breaks very lightly, then there is no clicking, only the normal squeaking from the breaks.

I was wondering one thing. When I put the car on park after driving it (even when the parking surface is flat and not inclined), the car rolls back slightly and then I guess it bounces back so it rocks a little slowly (this happens when I dont press the parking breaks). Is that normal for the Prius you guys/gals drive? I was wondering if that could have played a roll in the noise I hear, as in, maybe one time I was parking on a slope and the car rocked rolled back slighly and maybe put a lot of pressure on the part which stops it from rolling more and thus causing this noise problem (maybe by a part being broken/damanged).

 

Hello Tigran

Unfortunately, I have not yet found a solution, but I really haven't looked either. I am currently unemployed and have been holding it off until I get a steady income. I have kind of gotten used to it in that whenever I am reversing out of a parking spot, I apply it very softly and steadily and It usually makes less noise this way. Sometimes I even flip my car into "neutral" half way through my reverse so it is easier to break softly.

My click comes from both front wheel I think. As someone suggested when i originally posted, I removed the wheel and tried to see if I could find some pebble or such inside the brakes, but I didn't find anything, and frankly, I think its something mechanical (sounds like metal).

My understanding is that only the transitional brakes are used when you reverse, so that will explain why its still makes that noise when you reverse at a faster speed.

Anyways, I would really want this problem solved, so if you are able to come up with any solutions, please let me know as well. Thanks
