Analysis

Acft veered rt on touchdown. Heavy braking and differential pwr used to maintain directional control. Both rt side tires and the left outboard tire blew during rollout. Plt stated left main gear unsafe light illuminated during rollout. After engines were secured pax & crew evacuated acft. A pax stepped on airstep door to enter acft and rt main gear collapsed. Investigation revealed main gear cockpit lights were wired backwards, thus the false unsafe warning on left gear. Rt wheel inboard brake was binding when 100 PSI test pressure was released. Both brake plate assemblies showed evidence of heat. Disassembly of wheel ass'y revealed piston bores had been sanded down to point where 16 rms finish was removed. Both shuttle valve 'o' rings showed deterioration. Hydraulic fluid was of higher than normal viscosity and contained high concentrations of chromiun, aluminum and nickel. Brake ass'y were overhauled units installed 1832 hrs prior to incident.
