If I wanted to do it, I would hook a Mity-Vac onto the bleed nipple down at the slave cylinder, make sure the reservoir is filled with fresh fluid, and start pumping. Keep the reservoir full as you pump, and after a minute you will have drawn fresh fluid through down to the slave cylinder. Close the bleed nipple while still pumping, then you're done. Shouldn't take more than a few minutes to do.

Without a Mity-Vac...it gets a bit more time-consuming and messy.

one way we change fluid or bleed hydraulic "stuff" on aircraft is to fill the system from the bottom. we use a simple oil can like the ones with a trigger on them to squirt the oil out, we take a short piece of rubber hose and push it onto the oil can nozzle and then put the other end on the bleeder at the clutch cylinder and with the lid off the resevoir just pump till its full. this will push fluid from the bottom up and gets rid of all the air. you can open bleeder first to drain old fluid from system if you want all new fluid.

I have speed bleeders on my calipers and clutch slave.

I use a turkey baster to remove fluid from the master cylinder then swab out any dirt that has accumulated, failing to clean the master cylinder will get you eventually :)

then I refill, crack open the speed bleeders, attach a piece of tubing into a container and pump away while keeping an eye on the fluid level.

When clean fluid is showing in the container I close the speed bleeder and top up the fluid level.

I do mine every two years. DOT4 fluid.

I want to thank you for your advise to Mity-vac did the job. I hadn't heard of speed bleeders so I looked them up I may install a set.
THANKS FOR THE INFORMATION
Mike
