Rear calipers need to come apart. So here goes:
A little bit of concoction on the bolts and bleed nipple to loosen them up.
One bolt beautiful the other not? Strange.
And pull her apart.
Pretty grim looking inside.
New pads I think.
Now to get the pistons out with the air pump method. Problem here is that once the piston comes out of one side of the caliper you lose the air pressure to get the other one out. Thankfully they both moved so that when one popped out the other could be hauled out with a screwdriver.
It looks worse than it is. Pistons and calipers are serviceable.
Pistons are good to go.
Worst amount of crud seems to be in the transfer passages. Where the fluid passes from one side of the caliper to the other. Looks like they are filled with some sort of grease.
