I believe the brake problem was caused by a faulty seal, which may have been supplied to the part manufacturer by another 3rd party. This is a long chain of responsibility for quality control with MMC at the end of it. For Morgan to have picked up the fault during assembly, they would have had to disassemble and check every unit and even then a faulty seal may be very hard to detect.
This is interesting. A faulty seal may have been to specification when assembled, likewise the cylinder, but the combination failed in use. Was this due to the seal or the surface finish of the cylinder? Was the problem evident in new stock as delivered to MMC?
If the problem existed in new stock it is unlikely to be detected by MMC. Are new engines dyno tested before assembly? Of course not. Statistically relevant samples are tested by the engine maker. MMC would rely on the batch control report from their master cylinder supplier who in turn will rely on the same from the seal supplier. MMC’s involvement is to agree the unit specification, use suppliers in the whole chain that have current quality management certificates issued by independent quality procedure auditors and to check the batch report for each delivery.
The quality management system will get (has got) to the bottom of this and lessons will be learned. More important to us as customers is the apparent tolerance of the groundswell of comment on here and at dealers from the beginning. Maybe the situation was taken more seriously than I am aware. Is the MMC customer experience feedback system adequate?
