1972 CB450 front disk brake lever play issue

There is very little play (less than 3-4mm) on my 1972 CB450 front disk brake lever. The brakes work fine and the front wheel spins relatively freely for several rotations when spun by hand. Is the lack of play normal? I am used to a little more play in the front brakes on my Royal Enfield (with drum brakes) and other bikes in the past. I just don't want to get into a situation where I want to apply the front brake gradually and end up applying too much pressure as there is hardly any play.

Play in the lever is down to clearance at the rotor and pads, and flexibility of the piston seal; once those are set correctly, little play in the lever is normal. I have no issues modulating brake force, as it takes a bit of hand strength to get to maximum braking.

WintrSol, thank you for your input. Is it possible to adjust for more play? Or should I just get used to the disk brake the way it is and ride on..

Sorry this took so long to answer - as far as I know, the free play in any hydraulic brake system is fixed. Personally, I like that the lever tightens quickly, so I can apply just the amount of brake I need.

I rebuilt my slave cylinder last spring - scraped out the cylinder, new seal, and fresh brake system grease on the back of new pads - made a world of difference, since there was a build-up of gunk in the cylinder. The new seal has more flex, so the pads retract the correct amount, now.
