You shouldn't have to top up the brake fluid unless you have a leak somewhere.

If you don't top it up from time to time, you won't have to suction any out when you retract the pistons to change the pads. The brake fluid level can act as a pad wear indicator. The factory designs the master cylinder reservoir so that it won't run dry when pads get low.

Please figure out what is wrong with your brakes. You share the road with lots of folks who will appreciate it.

Pull the drums and have a peek. It doesn't cost anything and you can clean all the rust and brake dust out of there. I'll bet you find leaking wheel cylinder and contaminated swelled-up brake shoes.

I did several brake tests and cant get the rear brakes to lock up like they were. I have been checking the brake fluid levels and it has not dropped so there probably isnt a leak.

This is the reason the resevoir has a MIN/MAX level lines........
