Do you have the equipment to reverse bleed the system? A cheap way to do it is to carefully push the fluid backwards up to the master cylinder by pushing the caliper piston(s) in. Do it slowly, ya don't want to squirt the fluid out of the master cylinder and all over the place, watch for bubbles in the master cylinder. May take a few trys...or not.

Many people try to use the master as the pump,,the piston will travel farther than it should in the cylinder and mess up the O rings or seals...Use a vacuum bleeder that connects to the caliper bleeder screw,,,,,a few pumps and you're good to go.....this is the onlt way I do them..The bleeder kit are not expensive and are a good tool to have around for your other toys.
