thanks, i kept looking and see the line going to it, so i don't have to worry about that. i found something else strange. i was checking every thing out and in the master cyl it looks like it has oil instead of dot 3 brake fluid. i don't know if it is engine oil or hydrolic fluid. the brakes are working fine but i wanted to top off MC. i mixed a little out of the MC in a cap of dot 3 and it didn't mix just beaded up and floated on top, mixed some w/engine oil and it mixed up. i am going to try to call previous owner and see what he has been using when he gets back in. are those air tanks the long cylinders back on both sides of the frame? can i just toot the horn till the pressure goes down and take out a plug in bottom? thank you all, hr
