What am I doing up here?
A sad end to a great five day break in Thirsk. On leaving the M62 I touched the brakes and the peddle hit the floor. You don't half push it hard the second time,  nearly went through the windscreen. The offside rear brake slave cylinder pistons had seized, massively overheated the drum and brakes and probably boiled the brake fluid causing bubbles in the fluid. The brakes were smoking when I pulled up. Pistons cleaned and lubed with a tiny bit of copperslip today. This same rear brake overheated a couple of years ago, obviously a poor repair on my part. I must say "Rescue my Car.Com" were really great. Highly recommended and cheap too.

Glad you were not harmed.
I believe the rear brake cylinders are of very low quality. I had 3 replaced over a 10 year period. My garage are talking about lining the cylinders with some stainless steel material, as they are proe to corrode and stuck the piston.

Past Parts do a refurbishment service (UK company). R K Sleeving in the USA. I suspect also the Morgan spares (in New England?) are likely to hold stocks. First two from A Google search

1 would have thought new brake cylinders would have been the order of the day.

Gordon Yes and no - if you get the stainless sleeve in them you can say goodbye to the problem of inferior cylinders forever relatively. Providing you change your brake fluid every 3 years minimum.
