If you can't afford that thing, buy a large syringe at a feed store. Buy a small piece of clear plastic hose at the autoparts store to fit over the end and then a 1/4" piece of hose to act as an adapter that will fit over an M7 bleed valve. The syringe and hose will cost you less than $5. DO SUPERGLUE the hose onto the syringe and the 1/4" piece onto the smaller hose as they will blow off under pressure otherwise. You can't use speed bleeders for pushing in brake fluid as they have 1 way check valves that stop the brake fluid. Use regular bleed valves. Wrap your caliper in a towel and you may have to wrap the bleed valve with teflon tape so it doesn't seep under pressure. Keep the cap off our master cylinder and keep an eye on the level of the brake fluid.
