My brake fluid is a little low, can I just add fluid (dot 4).....Or do I need to drain and refill....and does it matter what kind....

 

It does matter what kind. Always use Dot4 you can just top it off. You don't need to drain it. If it seems a little murky or there's something in it i would recommend draining it but its not required.

 

awesome....so it doesnt matter if i mix brands, all that matters is dot 4???

 

yes. DOT4 is Dot4 its the same stuff there are standards so everything is made basically the same it will be fine!

 

Thanks

 

You dont drain it. If your fluid is low, its old and dirty. Get a piece of 1/8th ID tubing. Connect it to the bleeder valve. Fill up the reservior and put the cap back on. Apply pressure to the brake and open the bleeder. Repeat until the fluid looks clear coming through the tube. Make sure to bleed the air out, get a nice stiff lever and you're done.
