Can I use the same Motive speed bleeder to bleed a DOT 3 and a DOT 5 system?


I have two brake systems I need to bleed, one with DOT 3 and the other with DOT 5. I've already done the DOT 3 one so if I empty and clean it out real well can I use it to bleed the DOT 5 system? Thanks for your assistance.

Ehhh, I wouldnt.That is just me.

I would be concerned of contamination, when going from DOT 5 back to DOT 3 afterward.

That silicone based stuff is hard to get rid of. You may contaminate a few systems afterwards, even if you think you have it cleaned out well enough.
When it comes to brakes , better to be safe than sorry
Fact is stranger than Fiction

I’d say it depends on the application mostly.
Stock stuff I’d live with just cleaning it well.
