Dot 5 brake fluid

[Charlie71rt]

I purchased dot 5 silicone brake fluid years ago from Yearone, it was Quaker Supreme, I removed the master cylinder to get my booster rebuilt and need to bleed the brakes, I don’t see Quaker anywhere on google, now Yearone shows Super dot 5 silicone brake fluid, is it safe to assume I can mix brands as long as it’s dot 5 silicone? I also have access to Johnson brand locally.

Should be fine . Just can’t mix DOT 5 with 3 or 4

Dot 3 & 4 can be mixed , Dot 5 cannot be mixed , you need to fully clean the system if you switch from Dot 3-4 to Dot 5 , I like using Dot 5 as it will not harm paint

Dot 5 as it will not harm paint

Did not know that!

Watch out for DOT 5.1 - it is not compatible with DOT 5
Make sure the bottle mentions Silicone.
Why some dummy would come up with that numbering system is beyond me.

that's because they want to sell you replacement parts it really is too mean!
