Pretty simple assembly. Remove the boots & pull out the pistons.
If they have enough recess in the back of the piston a pair of snap ring pliers works good to remove them. If they are really stuck you may have to drive them out. Remove the cups & spring. Make shure the bleeder screw will come out & clean it up. You will need a brake cyl. hone. Hone the bore of the cyl till it is smooth. If you have any pits left that are anywhere but in the center, you will need to buy a new cyl. unless its a rare model which you will send & have it sleeved. Lube the cyl. with a little silicone or brake fluid & put the spring, cups, pistons, && boots on.
