Yes, you leave the cap off and make sure you keep the master cylinder full of fluid at all times. Bleed the brakes starting at the right rear and then moving to the LR, then RF, and ending at the LF.
Well if you continue to drive it with a defective master cylinder, your brakes will eventually fail, and you can end up having a wreck and possibly killing yourself or someone else. Is that enough damage for you? Replace the master cylinder and don't be an idiot.
The ECU for the ABS brakes is attached to the Master cylinder for the brakes.
master cylinder is sticking
. If you have the 4-port master cylinder, the bottom ports go to the rear brakes & the upper side ports go to the front brakes.

just the slave cylinder, for your brakes.
A brake master cylinder? If you are losing brakes or brake fluid.
probably have a bad master cylinder.
leaking brake line or master cylinder..? It sounds like a bad master cylinder. Years ago these could be re-built, but with the newer ones, they must be replaced. By pumping the brakes, you build up pressure which prevents the piston in they master cylinder from leaking, cut after sitting, the seals leak again. A good mechanic will be able to tell if it is the master cylinder or not.
Any sudden brake loss can be the cause of 1. brake line damage 2. master cylinder disfunction
Bleed the furthest from the master cylinder 1st then the rest in order of distance from the master cylinder.
