Today was messy as I had to strip down and start to clean up the hydraulic clutch and brake parts.
There is always a risk of parts being seized solid or even snapping off as brake fluid is very corrosive.
To ease into it I decided to refurbish the hydraulic clutch master cylinder first.
Here are the parts fully disassembled prior to cleaning. New seal and piston kit in the box at the back of the photo.

Due to it being a messy process I have no photos of the 'during' phase but here's the finished cylinder, fully cleaned and with the new piston and seal kit fitted.
Next job was to strip down the rear brake and master cylinder. You can see how badly corroded the pistons and bolts are. New pistons required. Replacements are not chromed steel, but Teflon-coated aluminium, much better for heat transfer and also the coating means the pistons are easy to slide and easy to remove in the future. These pistons were VERY difficult to remove.
Moving on to the front brake system I saw some parts that were damaged already and one that snapped as soon as I tried to remove it. This will be challenging to remove now.
Finally I managed to dismantle the calipers. Tomorrow I will clean them and then give them a few hours in the ultrasonic bath before cleaning them again and reassembling them, ready once more for action with new pistons, seals, hoses, pipes, pressure switches, clips, pins and brake pads.
