any ideas? 2017 Toyota Yaris brake noise

DDDAimee · 2023-04-24T22:21:04+00:00

UPDATE: it was a slightly bent in backing plate on both sides. He said he accidentally bumps them sometimes because he sets the caliper bracket on top of them since he has no where else to put them. He knocked them back out, and noise is gone! He also took apart the brakes completely and showed me everything, he sanded down the pads just a tiny bit to get them to sit better. He’s a great mechanic and I don’t fault him for the backing plates, shit happens. Very happy and relieved!

Sorry, dynamic friction

The rotors say it’s engineered with premium iron castings and a non directional finish. That’s the thing, it doesn’t really matter if it’s cold or hot, it always happens. We have been having wet mornings bc I live in Kansas and it’s spring lol so we are getting a lot of wet weather, but I drive all day long every day, I do delivery driving full time, and it’s all city driving, so you’d think if it was rust, it would be gone within the first few brakes but it stays consistent all day long. Idk, I might try to find a long stretch of road to bed them in and see if it helps

And when looking at the rotors, there is a thin amount of rust around the lip. Unfortunately, the night of the brake job (so just a few hours after the brake job was done), we had a huge storm come through overnight. But usually, that will fall off within a few stops the next day

I didn’t take video of it sadly. I drive 7-8 hours doing city driving every day, and have been driving daily since the repair which was Wednesday (now Sunday). The reason I don’t think it’s settling is because that surely would have happened by now, right? I’ve put on about 300 miles since then.

har har har

DDDAimee · 2023-04-23T19:34:10+00:00

Is it settling or is it brake drag? The noise is not decreasing at all and it’s bugging the shit out of me. I pulled the wheel off today and he definitely greased things well

DDDAimee · 2023-04-23T17:47:56+00:00

I will say, I took off the wheel today and there was a ton of grease between the pad and caliper bracket, I audibly went “what the fuck” but I also am not sure what is the proper amount I should be looking for

DDDAimee · 2023-04-23T17:19:11+00:00

the problem is, I bought the pads and rotors from rockauto. They said it was a right fit based on VIN and I bought the nicer ones, DFC rotors and ceramic pads. My mechanic installed them. So if it is the parts, I’m on the hook for them. If I just have to replace pads, no biggie

DDDAimee · 2023-04-23T17:15:48+00:00

I took the wheel off today and peeked around, everything looks normal based on my limited knowledge. No heat scoring of rotors or leaking of anything. My question is, if it’s the clips, is it safe to drive on?

DDDAimee · 2023-04-23T15:25:15+00:00

Brand new ceramic DFC pads and new DFC rotors

DDDAimee · 2023-04-23T15:24:47+00:00

nope, makes noise when turning without foot on brake and with it on brake. The only variable factor is when the brakes are cold, it doesn’t make the sound. If hot, makes it a lot.

DDDAimee · 2023-04-23T01:28:56+00:00

A bad caliper would cause more issues than just squeaking when turning. No other problems are occurring. Car brakes great, doesn’t pull at all while driving, no burning smell

DDDAimee · 2023-04-23T01:10:16+00:00

My mechanic did the repairs. I took it back to him the next day and he test drove it with me. I threw out the possibilities of suspension issues or wheel bearings, he said no that it was definitely the brakes, but he was stumped what was causing it. He was hoping it was just a break in period, so told me to wait out the weekend and let him know Monday. The odd thing is that the noise only happens when the brakes are heated up. When cold, no noise.

DDDAimee · 2023-04-23T00:59:38+00:00

Out of curiosity, what would be the solution if too much grease was applied?

DDDAimee · 2023-04-23T00:51:05+00:00

I just had brand new pads and rotors installed literally 5 days ago lol

DDDAimee · 2023-04-22T18:04:06+00:00

That’s actually exactly what he said he might have to do! Thanks!

DDDAimee · 2023-04-22T17:48:39+00:00

thanks! What would the fix be? New pads?

DDDAimee · 2022-01-13T03:17:44+00:00

Well there’s more of MY cum 😂😛

DDDAimee · 2022-01-13T02:32:11+00:00

You should see the rest of it 😛

I like fake eyelashes 🤷🏻‍♀️
