You assume correctly Dave! The details are on the DVSA website: PREMATURE DEGRADATION OF THE RUBBER SEALS IN THE BRAKE MASTER CYLINDER

Reason for recall
Investigations have identified premature degradation of the rubber seal(s) in the brake master cylinder compromising brake performance and in extreme cases causing brake failure.

How to check if the vehicle is recalled
Contact the local MORGAN dealership or manufacturer. You will not need to pay for anything involving the recall.

How the manufacturer will repair
Replacement of the master cylinder or the master cylinder seals.

Number of affected vehicles
1274

(Note that the site asks you to specify Plus Four or Plus Six and year of manufacture, but the details are always the same).
