Never liked the idea of clamping the brake lines.. seems like it can't do them much good. Instead, I wrap a big elastic band round the brake lever and grip (closes off the flow through the master cylinder).
The outer dust seals on the calipers can be picked out easily with a fingernail. The main seal is a bit trickier as it's deeper in the cylinder and much thicker, you can lever it out with a small jeweller's screwdriver, but take care not to damage the outer face of the slot the ring is seated in. If you've a suitable bit of steel wire about a millimetre in diameter then flatten and bend the tip you can hook the ring out from the back. Diagram might make the idea clearer:
