2 different brake fluids in the car?
is it ok to use 2 diff fluids in the mast cylinder? was doin brakes yesterday and caliper came off so had to top off the master cyclinder with fluid which prob isnt the same as the one thats in the car.. this should be ok right? or should i do a brake flush? this is for a 99 integ se

as long as you use dot 3 or dot 4 (both aren't synthetic) you should be ok. make sure its from a sealed container, not something thats been sitting in your garage for years since brake fluid absorbs moisture

cool thx

No its not ok. A flush is highly recommended.

shouldn't need a flush. Like nickmak said, as long as it's clean and from a sealed container

Iceman-19 05-27-2009 10:55 PM

......I would recommend a flush.

If you don't know which standards the two were based on then a flush is a pretty damn good idea.

Dot 3, 4 and 5.1 can be mixed.
Dot 5 is silicone based and cannot be mixed with the other 3 types.

As long as the fluid is from a fresh bottle, all is good. Just make sure you flush the fluid once a year.

What cars come with anything but Dot 3 these days? I can't think of any offhand but it's usually only in the owner's manual.

alot of the euro cars use dot4
