The cap should be tight on the master but this will not make the brake spongy, it sound like you have a brake caliper slide that is sizes or there is air in the lines, please check for brake fluid leaks at each of the wheel as well. This guide can help with the calipers

And this guide will help with the air in the lines and ABS
