Hey guys my rear brake fluid is on the lower side and was wondering if you could just refill the resovour back up to the top with the older fluid still in it or do you have to drain it out. Also if you dont have to empty it out, do you need to refill it with the same brand of fluid thats in it already or can you just refill it wth any brand of brake fluid?
thanks dudes

Most brake fluids are spec'd the same. I know there are different ones as well...So I might suggest you bleed through the old, thus flushing it and filling with new. Generally it is not good to mix chemical based anything. There can be reactive elements. As for the bleed you can buy a pump/vac and do it yourself. They are like 30+ clams

No Mix. Flush system.

unless you know what kind is in there, dont add some. if you dont, flush it. its not that hard to flush.
