Hi Sukram.
If you're looking for a technical answer I'm not your man, however I have had many an issue with flexible hoses on bikes, predominantly BMW's.
Flexible hoses suffer more than most through lack of fresh fluid in them. They often look perfectly normal from the outside and you should always bend them to look for cracks as I'm sure you know, but they swell and break down on the inside surface leaving the fluid to get a much smaller diameter through which to operate.
Symptoms are usually attributed to master & slave cylinder breaking down or callipers not working correctly, or even clutch plates sticking if it's a hydraulic system, whereas it's the flexible breaking down.
In real terms, they are cheap enough to replace when you change the fluid, but change the fluid regularly and the need disappears. I'd say a realistic lifespan is six years upwards on a regularly used and maintained Morgan.
Any use..?
