2 separate fluid containers in the master cylinder. Front is small. Back is big. My front keeps goin low. Is front for front brakes. Sorry for dumb question. But to dark cold and rainy to check and my clymers manual says nothing

 

I believe that is for the rears might check to see if you see anything wet back there

 

Leaking rear wheel cylinders or rusted out brake lines most common problems.

 

The front chamber is for the rear brakes...Mark

 

Thanks all. I got it on a rack. Will check it out after work tomorrow
