Brake fluid appears to be low. The only resevior cap is a small cap covered by a rubber cover. Appears there are threads on the outside of the small plastic piece? Then there is only a small, pin hole size opening in resevior itself. How do you ad brake fluid?

Hi: I own a 1994 Honda Accord LX. The piece you refer to is only the upper cap. That portion is basically a breather area and the tiny hole is a breather hole.

To remove the cap to add fluid is easy. The larger gray colored cap below the small one you referred to is the one you want to remove. The smaller one will stay on top of the larger cap.

You'll want to turn the lid to the left about an inch or so. It does not screw off like a threaded cap, but instead turns only an inch or so, then lift straight up. There are multiple little hooks on the under side of the cap and rails on the cup where they basically twist and lock into place.

It's pretty easy. Give it a try. It should come off.
