If you changed out your clutch master cylinder, you'll probably need to bleed any air out of the line.
It would be best to get a Mity-Vac unit and bleed the line that way.
All you do is read the instructions, connect the unit, squeeze a few times to draw a vacuum, then open the bleeder valve.
You can then continue to pump the Mity-Vac and pull fluid down the line from the master cylinder into the catch bottle at the Mity-Vac side.
Just be sure and monitor the fluid level at the master cylinder reservoir.
It will empty quickly since it has less capacity than the brake reservoir.
If you're doing this yourself, just close the bleed valve and fill the reservoir and start again.
If you have help, they can just continue to fill the reservoir while you're pumping the Mity-Vac.
When no air bubbles are viewed in the clear hose to the catch bottle, close the bleed valve and check operation.
Just be sure and don't spill any brake fluid on painted surfaces. It will damage that paint.
I usually wrap a shop towel around the reservoir to catch any fluid that may dribble over the edge.
You of course can use this method to bleed your brakes, or to replace the fluid with fresh fluid.
