In relation to the comment "Firstly on the question of what was actually the cause of the brake master cylinder problem. Putting on my former production engineer/industrial designer hat I can say you will never know, or at least from formally from MMC. Due to the string of companies involved in the production of the master cylinders, metallurgical suppliers, casting companies, rubber compound and seal manufacturers etc there are a number of avenues where production could have gone wrong. It is most likely that MMC have accepted settlement containing a “gagging” order and would have been advised not to make any further disclosures. It is normal industrial business. Morgan dealers would have been also told not to make statements as to the causes. So basically on TM you may as well drop the question." r Any one who is interested may submit a carefully phrased request of the DVSA under the Freedom of Information Act - you will receive partially redacted but interesting details of the circumstances which may be challenged by reference to the Information Commissioner if you wish to take it yet further.
