Yes. Driving a vehicle without proper endorsement is the same as driving with no license at all.
However, with US law, vehicles which do not fall into the requirements for the operator to possess a CDL do not require any special permissions to operate air brake equipped vehicles. Motor homes, farm use vehicles, firefighting equipment, military equipment (operated by military personnel in the course of their duties), and vehicles under 26,000 lbs. GVWR (so long as they are not carrying hazardous materials or more than 15 persons), do not require a CDL, and thus do not require any special permissions to use air brakes (on a US licence, there is no air brake endorsement - only a restriction placed on CDL licences if you do not meet the testing requirements).
That depends on which country you live in.

You need to replace the rear brake pads and anything else the brakes may need. Driving without rear brakes would be foolish and dangerous. Good brakes are a number one priority.
For the most part, no, but there are some states which require it (New York is one).

In the US, no - there is no such thing as an air brake endorsement - only a restriction for CDL holders who don't pass the written air brakes test and complete the pretrip and road tests in a vehicle equipped with air brakes, which prohibits them from operating vehicles requiring a CDL which are equipped with air brakes.
