That's a full day of work, 4 x new front cylinders, new master cylinder, much better and more "bouncy". New rear hose (misses the metal wrap which would have been helpful. I need to bleed again in the morning, as still spongy, but much better. A slight pull to left now (swapped top and bottom pad) and aligned backplate a little, greases everying up and cleaned. I suspect if I adjust front right she will balance out. No locking.
A long day, 12 hours of work! Can get a drum off in about 3 minutes now and getting quite good with the old split pins!
