Would appreciate some comments about an issue I had recently.
Took my 2014 Accord Hybrid into Firestone in May 2019 for new tires. They suggested that I really needed a brake fluid flush so I did it. Then in July 2019 (2 months later) I had to go to Honda service for another issue and they told me that the brake fluid really needed changing and the tech said it was brownish/copperish in color and should normally be clear(er). I kind of got on their case and explained we had this done two months earlier and of course didn't have it done.
Now last week we had to bring our car back to Firestone due to a tire repair/replacement (we have their road hazard). When the car was ready they listed on the services needed that the brake fluid needed changing. Their test showed 200 ppm and that was actually pretty bad.
I asked him a few questions about the reliability of the test (they use test strips and visual of fluid) and it sounded like the test was pretty "sound". When I explained to him that they did this in May and he looked it up then he started with some technical explanation basically explaining that it could have been so bad in May that it didn't all get flushed out, etc., etc..
Was he feeding me a line of bull??? Would appreciate any insight or thoughts in this since I'm not mechanically inclined.

Bull.

And honestly, it doesn't need to be flushed that often. It's ok if it's dirty.

It does need eventual maintenance but dirty will still work.

Or that possibility that it wasn't actually replaced the first time. Quick lube joints are famous for charging and not performing the task.

Follow up on the 2nd brake fluid flush...
The tech made a note to keep the before and after test strips, which they did.
The test strips he showed me were in the 200ppm range before and after it was on the low end (as expected).
He still held his ground and said it the reason why it was back up to 200 ppm 3 months after they did it was because it must have been really bad off, so bad that there was still stuff in the system after the flush.
That didn't make sense to me because I had the brake fluid system flushed about 30 months prior so I'm inclined to just stick with the scool of thought that they failed to do it the first time.
I didn't argue, it was free, I left and not sure if I'll want to trust that store again.
