Narrative:

Aircraft X was landing runway 15 with aircraft Y in the left downwind for runway 15. I issued aircraft Y traffic on aircraft X and aircraft Y reported traffic in sight. I told aircraft Y to follow the traffic and issued a landing clearance. Aircraft X landed and was told the exit at A5 or A6 and to expedite off the runway. Aircraft Y was coming in quickly behind aircraft X and aircraft X was not exiting fast enough so aircraft Y was issued a go around. Aircraft Y asked me to repeat myself and I told him again to go around. Aircraft Y didn't and landed runway 15 with aircraft X somewhere between A5 and A6. Aircraft Y exited at A2 and was issued a brasher with ground control. When he called the tower; he said that there was an equipment problem that made him unable to execute the go-around.aircraft Y's equipment problem might be considered an emergency situation due to it preventing him to execute a go around. Equipment problems like that should be made known to the controller so that the controller can accommodate.
