Metal shavings in brake fluid

[Mysterylectric]

So, I’m sending out calipers from a 100D for paint, and I noticed the brake fluid draining from the calipers is loaded with metal shavings. I don’t have an analysis yet, but the fluid will be sent to the lab to see what’s going on. Has anyone seen this before?

You're really not supposed to have them, but it's not a first. Could be anything from wearing pistons to something more catstrophic. There's not a whole lot of grinding parts in the system, so usually a good flush to make sure you're not running too much water in the lines solves it and keeps friction down.

did you see the shavings in all calipers or just one? if all, its probably not the pistons, more likely the abs controller. but regardless a good flush with the proper fluid should fix it!

Update: owner says the vehicle was in a pretty decent front end collision, and needed a new iBooster, ABS pump, and a few other components. I’m going to assume this is the cause of the contamination, likely due to improper flushing. A full flush has been done, and the fluid is clean and clear now.

Bit of fun news that.
