Oddly it has been it has only been 4 months this week.

 

[SeattleCat]

Feels longer. Which is odd as most things these last few years feel like they were yesterday when they were a long time ago.

 

[He Keith]

Trust me this feels like forever, but I only have 1925 miles on the car in those 4 months.

Because a picture is worth a thousand words... This is July, September and so far October. I received the car May 31. This is the days at the dealership. What is starting to annoy me is the car has been there going on 6 days and last communications was 5 days ago. I have prepped the "demand for repurchase form supplied by state for lemon law claim and will call the dealer today for an update. As much as I love the car I am worn out. 31 of 126 days the car has been at the dealer. IHU I would hope the October update may resolve, but the brakes are the baffling repair that I believe has Volvo stumped. They just refuse to try the Powerstop ceramic truck pads (designed for towing) that I purchased to see if that fixes the issue. One Audi dealer has me on a list for a Q4 and I will put a deposit with a second dealer.

Because a picture is worth in my case 32 cents here are all 4 of my wheels and brakes showing their in good old Seattle.

 

[He Keith]

Darn man, how are they that clean. Mine are never that clean, mine always have some oxidation look to them. This looks brand new.

 

[SeattleCat]

Ikr. And I have driven down to ca with them along the sea. Driven in sand. ..

I do spray that wheel stuff right in there when I wash the car. After that they are even shinier.

 

[He Keith]

Hmm, maybe I need to spray stuff in the pads/rotors and see if that helps. But don't you drive right after washing? Been trying to talk to dealer to see how their test went where they wet the brakes and parked it over the weekend.

 

[SeattleCat]

I do drive after washing as I have to go to car wash.
mans yeah they rust before I have even finished washing the car so they get 3-4 40mph P brakes on the way home. Which is getting a little old

 

[He Keith]

That is insane. No way I am doing that every wash. I suspect they will be buying mine back. Sad as I like the car and even my second choice Q4 is not likely to be as fun or good to drive.

I have had my P8 3 months and 2,000 miles. Only once (posted here 18 days ago) did my rear brakes seize after a rain -- no fun. Since then I've tried to replicate the situation after driving in the rain and letting it sit -- but to no avail. No seizing. A mystery so far.

Wet the pads/rotors up and park it overnight or 1 day and I bet they seize.

 

[SeattleCat]

Might be also a function of the acidity of the rain and what was in the road on which the puddles you went through were on.

I recon it would Take a 1 minute drive to clean breaks after wash.

Full power to 40 P brake. Repeat 3 times go home. Your drive might be big enough.

Warning. One does look “special” doing it.
I am waiting to be pulled over by the police one day.

a temporary 30 sec regen suspension mode would be so much better.

 

[He Keith]

For me I just take county tap water spray a bit on the pads/rotors, park it and bingo, 13-14 hours later a cluck, let it sit longer and a louder clunk and risk of more pad breaking free or possibly lodging between pads/rotors causing on going grinding.

 

[Vatorney3]

The wheels/rotors/pads were quite wet from driving in rain -- enough to leave small puddle on the garage floor (like before when they seized). Although I have washed the wheels and sprayed the rotors/pads as I normally do with a wash, I've not directly forced water into them at point blank range. I'll try that next time, which will be soon.

I wonder if your County tap water is significantly different (chemically) than rain water or my wellwater.

 

[He Keith]

Dealer is in different water district and I believe he produced it. The brakes don't get as wet while driving in the rain as when you wash the car usually. Driving wipes them clean pretty quickly. I would like to see someone try it and report back, just knowing it will lead to a dealer visit afterward to get the pads/rotors replaced.

I pulled my car out of garage on Saturday after noon, vacuumed, cleaned the inside and decided to wash. Washed the car. Put car in garage and did not drive it again till Monday. No issues whatsoever. I didn't put any cleaner on the tires or wheels just soapy water and sprayed them off.

@He Keith I am curious if your washing routine plays a role here. I’m in Atlanta too but have only had one moderate “clunk” experience with no permanent damage, and that was after sitting for quite a few days. I wash in a drive-thru and park outside, and do nothing special like the high-speed P-brake trick.

As am experiment last week I simply took a spray bottle with water in it, wet up both rear rotors and pads, rolled car back in garage and 14 hours later clunk. Not sure why I have it so often. Also while you had a clunk I would bet if you had dealer pull your pads some pieces are missing now. My first time was a minor clunk and when I brought it in for IHU they pulled pads and noticed damage and did the pads/rotors. Most clunks will not result in grinding, but will likely pull some pad material off. The time I let it sit 4 days it pulled enough big chunks that got stuck in there that the brakes were grinding while driving.

I think that is the concern, many people hear a minor clunk and don't think anything about it, but if they pulled the pads there would be damage. How much brake material needs to be missing to compromise the brakes in an emergency stop?

And again my washing routine has not changed in 29 years and around 2 dozen cars. My County water is actually pretty darn good, not heavily minerals or such.
