I have a question. I see the videos and seeing the step by step process of replacing the front brake pads of a Honda Sabre 1100 VT C2. At no point does it ever state to pull off the cap to the master cylinder. How are you compressing the caliper piston without creating room in the system for the hydraulic fluid to go somewhere?
If you look at the level before changing pads will see it low so when you compress calipers fluid usually goes back to normal level ---now unless you had added fluid then you need to remove the fluid you have added so not to over flow master --
When your pads wear the fluid stays in calliper. When you push calliper back, you are just pushing fluid back into resorvoir. This is also a way to check you brake pad level if no one had added break fluid. You only need to bleed if you have gotten air into your system.

The fluid cap is not 100 % leak proof, it can release some air
But you are right for easier pressing back the caliper
You have to open the resorvoir cap.
