East African Airways, Super VC10, 5X-UVA, accident at Addis Ababa, Ethiopia, on 18th April 1972. Report No. AI 11/72, dated 1st February 1973, released by the Imperial Ethiopian Government, Civil Aviation Administration.
A 21 page summary of this report is contained in ICAO Circular 132-AN/93, Aircraft Accident Digest No. 21, published in 1/1978. I have a copy of this but I do not know if the truncated data would be sufficient for your needs. There are no appendices and only on of the original diagrams (the FDR trace).
You are correct in your assessment as the probable cause is given as:
"The accident was due to a partial loss of braking effort arising from incorrect reassembly of part of the braking system, as a result of which the aircraft could not be stopped within the emergency distance remaining following a properly executed abandoned take off procedure."
