I am not sure what you are referring to and it could possibly be an after market domponent. How about posting a picture of the component you are referring to?
The brake pedal sinking to the floor indicates an internal leak of the master cylinder and is going to deteriorate further.
For the engine, ensure you have sufficient engine oil. It is ok to run the engine but for the brakes, being a safety issue, you should get it resolved as soon as possible as the brake can fail anytime.
