Debris in Brake Reservoir

[Roady68]

I had to hook my battery tender back up and decided to check fluids as weather will be breaking soon. As I looked into the reservoir for the master cylinder, I noticed a lot of black specks of debris. Anyone have an idea? Looks like I'll be taking back to the dealer once weather is decent.

Huh, I just checked mine, very quickly today and I didn't notice anything.... I'll have to double check.

Does it get tracked? I've seen that but only on old cars where the rubber hoses start breaking down...

Car has 1500 miles. I ordered it before they weren't going to be available anymore. But work assignment has me away so it never gets driven. Never tracked.

If it was my car and I found all the debris in the reservoir. I would suck out what is in the reservoir. Then flush and bleed the system.

if this was my car and its under warranty , don't take it out ,, bring it to the dealer so its documented and let them deal with it , you may have a more expensive issue on your hands . If it was out of warranty id change it out myself but you have a warranty so bring it back so its documented.

Once weather breaks, its off to the dealer.

What did the underside of the cap look like? Is that rubber from the seal?

Is the car a manual?

If so then I’m sure it’s because the clutch master cylinder and brake share the same reservoir. Clutch fluid gets dirty like that. That is one of the reasons some divorce the brake and clutch reservoirs. It keeps the brake reservoir clean. I divorced my systems and my clutch fluid looks the same while the brake is clean. It isn’t “bad” but clutch fluid change is done as routine maintenance every few frack days.

Dont want to hijack the thread but could you give some details on how you installed a separate clutch reservoir? I've been looking to do this on my '21

No problem! Pretty straight forward. Bought a brake reservoir from an auto car. The brake reservoirs come as an assembly with the master cylinder attached from ford. You can buy brand new or from a scrap yard. I bought 2 from Midway Mustang. Then you need a remote reservoir for the clutch. The popular one is the GM part for a 2008 GTO but is getting harder to find and cost more than necessary. I’ve seen others use Willwood options. Then you just need hose that can withstand brake fluid. Last is a mounting solution. Some have zip tied the remote reservoir to the brake reservoir but I wanted a hard mounted solution so a simple angle stock did the trick.

Also no need to replace the brake master cylinder. Just detach the reservoir from the master cylinder. When doing so, be mindful not to dry out or get air into the MC otherwise you’ll have to bleed it. Whole thing ”should” take less than an hour.
Here is my set up

come on, ford did this dumb shit with the brake and clutch fluid together ? Chevy did this is 10 with the Camaro and it was dumb then . I have a t56 magnum in my 99 trans am and that fluid gets dirty every year and gets dark too . What a bad idea!

Thanks for the idea. Yes, its a manual and I may do this modification.

Yea I don’t understand how you make an entire kit to “fix” this for the previous generation but do the same for the newer one. I get Shelby isn’t ford but still. Oh well

Yes, a manual. Car has 1500 miles. I doubt its had a chance to get too dirty. I will see if I can fish some out. I was toying on replacing fluid with Motul so it would get a flush. The reservoir separation is a good idea that I may implement.
