I slammed the brakes on rolling back and forth. If I have to wash then drive then Volvo will be buying the car back after the 4th set of rotors and pads. I also dried the brakes with my blower below to make sure the rotors were dry.

If slow moving not enough kinetic energy stored to convert via friction to heat.

I would argue that the method being used it not working.

But you have been doing this for a while. Anything different this time than others that did not break
The car ?
1. Time until driven?
2. Temperature?

 

Was 3 days before I drove it, temps were a little cooler and we have a lot of rainy humid days. It is not the first time I have washed the car since getting the brakes done last time, this is 3rd wash since. If I have to worry about weather, humidity and making sure I drive the car after was then this car is junk. Oddly even under mild braking they seem to engage the brakes now as even when I was driving slowly and applied brakes the noise got worse so it seems they do at least make the pads drag a bit, maybe to trying to avoid these issues. Also the IHU is acting up again, might be the Spotify app, but I doubt it, once I start playing a song if I hit pause on the screen or the pause button the music will not stop. I am so conflicted, I really like the car when it is no issues, but if every other month I need to have issues fixed it is not worth it.

I already email Volvo and dealer reminding them this is attempt 2 at brakes and when I bring it in will mention the IHU/Software as another issue. I figure at this rate by end of year or a little after, wither the car is fixed of they will have bought it back. And no way I would get another one.

 

Here is clip right after I started driving this morning if you crank the volume up you will hear it while driving and then when braking.

Almost sounds like yo have a warped rotor maybe.

 

Yuck ….

that is not a good sound

 

Next time It goes to Volo on a flatbed maybe if Volvo keeps paying to flatbed my car they will get the hint. I wish I had waited for the dashcam to finish booting to hear the clunk. I will go through the cam footage tonight to see if it caught it.

 

Just talked to service manager, he will have loaner ready for me and have shop foreman handle the car and contact Volvo. I will also talk to Volvo as it looks like they will again have the car for a while. Was very clear to Volo in my email that as soon as the car meets lemon law requirements I will file for them to buy it back.

 

That is unusual and you don't hear many others with this problem. I haven't changed my ways from my previous cars and get car washed at auto car wash normally once per week then drive home normally about 2 miles and park in my garage. I only drive my car 3 or 4 days a week and not had any problems with brakes.

 

Maybe they need ceramic discs. No rust problems.

 

My suspicion is the pad material is not very strong and when the brakes seize the clunk is part of the pad breaking off and the grinding is that piece wedged in between the pads and the rotor. At some point if they do not reformulate these pads they will be buying my car back as I don't see this being the last time. I am even careful when cleaning the car not to get wheel cleaner or anything back into the pads. Total ridiculous that I have to worry that any time I wash the car I may create a break issue. I really was debating C40 to replace her T5, but I am a "One and Done" mind set for me with Volvo.

I would be more understanding, but every time is a debate with dealer about a loaner as well., "first come, first serve" and I was like you have had my car 3 times I am not going to keep renting or ubering around.

 

Oh my, so sorry to hear that..... to Seattle's point, Volvo needs to pinpoint the root cause, otherwise it's as good as suggesting that after every wash (assuming it seizes up), bring to Dealership to replace pads AND rotors while leaving the Car at Dealership for a week. Simply doesn't make sense -- there's a bigger issue here. For ANY car, we shouldn't have to drive it back and forth or ensure all wheels are dry before parking in the garage.
Since my own incident of the pads and rotor replacements in June, i've washed the Car several times....thankfully, have not experienced the same ordeal.

I hope they're able to shed some light at the Dealership given this is a repeated issue ! And costly to Volvo as well.
Let us know what the outcome is....

 

I am baffled as I have washed it twice before this latest time with no issues. I wash my car the same way every time. I always wash my P8 and her T5 at same time. Her T5 gets less use than mine and sits just as long, no issues there. I try to wash it 1-2 times a month. At this rate pads and rotors every other month will get very expensive and I will start having Volvo send a flatbed next time. If they are just going to put same pads and rotors on then I see me back again in a month or so.

And I agree I am not changing my habits to protect the brakes. I may start reaching out to a lemon law attorney to get some advice as I would think brakes are a safety function and I am not sure the law gives them as many attempts for safety related failures.

 

I am glad I at least glad I got the $750 gift cards, but honestly not worth all this hassle. I would prefer a trouble free car. No way I see this car going 6 years for me. Really wishing I had leased then I would beat the heck out of it and throw them the keys in 36 months.

 

I forgot about my security cameras. The below link is the video from 2 of my cameras. The camera in the basement garage doesn't have sound which is why I put the outside camera in the corner as it has sound and you can hear the massive sound of the pads being ripped from the rotors.

"Ripped" is a pretty strong word.

 

I would rather never hear any sort of ripping sound around Margo …

La la la places hands over his cars ears

 

Better than a crunching sound ;-)

 

La la la. No bad sounds for my car. Just a quiet purr ….

I hope they fix your car soon as you have had awful luck. It can only get better right?

 

Not sure. If this keeps happening they will be buying my car back soon. This is 17 days without it combined and brakes classify as a safety issue I would think where they get 1 attempt to fix them, and they have had 2.

 

Oddly I can't find many part numbers for much of the P8 online. When I look at the parts they replaced on my P8 it was:

31687441 - rotors, that come up as XC60 XC90 rotors online with 18 braking system
32287446 - pads, that come up as a wide range of Volvos

If I am looking up the gas 2021 XC40 online correct; that rotor appears to be either 31471476 or32300123 and the pads comes up as 32276933 (replaces 31471471) or 32276934 or 32276931 (replaces 31471408) 17 or 32300811 18 as well as a few more options, but never see the same number listed as for the P8.

At the end of the day my guess is the pads are the issue in that the material binds to the rotor. I wish there were decent third party ceramic pads to try, but I can't seem to find any. Trying to fond some third party ceramic pads to try.

 

OK, so EBC got back to me and they say their DP62246 is their version of Volvo pads 32287446. I have always like EBC brakes, was hoping they made the Red, but Green will do. Now to see if I can convince Volvo to try them and still warranty me.

 

Are they ceramic?

 

Says Kevlar, but I have an emall back to them asking if they have metallic content or are they just ceramic with kevlar. I used the Red Stuff on my Audi A6 and really liked them. They had good stopping power and lowered the dust from the Audi considerably. The green stuff should be fine for the rears as they don't do much braking.

 

Their answer back is they are "organic" and will not disclose the contents, seems odd, but my guess is they are not very metallic if any metal at all. Service manager is on vaction this week so will wait until he is back next week and see if he wants to discuss with Volvo to try them and see.

 

I assume organic means natural and the opposite of the toxic metal dust our normal breaks produce. One of the many reasons I like evs for the regenerative non metallic dust creating behavior.

hope they go well.

 

"organic brake pads are a real thing and are made from natural materials such as glass and rubber, often reinforced with synthetic Kevlar, that have been bonded together with high heat resistant compounds. These kind of brake pads are the most inexpensive option, they are much softer, quieter, but also wear much faster."

Also I found an interspersing thread on a Subaru forum where the answer was ceramic pads and the person upgraded to slotted rotors.

Gen 5 - Can brake pads fuse to the rotor due to rust?

Hey everyone, I have a 2016 Outback limited with 41k miles and it's my first breakdown. What do you think about this diagnosis from the dealership? Symptoms: After starting up and putting car into gear (drive or reverse) I can hear the car shifting and the RPMs drop once it is in gear as I...

Now I need to convince Volvo to try this and still support it under warranty.

 

Lawyer said the brake issue is not serious enough to qualify as a safety defect and thus I need to meet the 3 attempts or 30 days out of service.

 

Would this be considered your 2nd attempt ? Does all 3 attempts have to occur within a specified time period ?

 

This is attempt 2 for brakes, but I am thinking clock will be the trigger since I am at 19 days (2 for phantom keys, 12 for first brake repair, 5+ and counting for second brake attempt.) In GA after 3 attempts you need to send a demand notice and give them a final attempt, I believe at 30 days they no longer need to be given any more attempts. I figure at best I get the car back later this week or next week which will be around 24+ days. And if all they do is pads and rotors again I expect this to happen again in a month or so. If they fail again I assume even Volvo will not want to try any more as I think they are baffled now as well. I will suggest to them to try OEM pads that are organic or ceramic as long as they support the effort and not tell me I am on my own.

 

Dealer called, calipers are on order. I suggested they talk to Volvo about trying organic pads. There is no ETA on the calipers, but sound like a few days at best.

 

Good luck.
