A bit of quality time in the garage saw the final stages of the hydraulic cylinders overhaul.
The repair kits costing about £5.00 each were fairly easy to do. A small amount of brake fluid eased the rubber seals into place nicely then the bores of the cylinders wiped with fluid to help with the re-insertion of the pistons.
So, after nearly after a year, the refurbished clutch and brake master cylinders are ready for putting back in the car along with the clutch slave cylinder. I obtained some pipe (black in picture) that will hopefully be good enough for between the clutch master and slave unit.
