There's no howto you just need 2 syringes (say 50ml) and a short piece of plastic or silicone tube.

Open each nipple in turn, doesn't really matter which order.

Couple of pumps of the pedal to expel dirty fluid out of each slave cylinder or simply let gravity do this for you.
Let half a cup full out.

Make sure Master level is down to minimum level each time.
Then pump in fresh fluid into each slave nipple with said syringe.

Use the 2nd syringe to extract excess fluid from the master.
Obviously don't let it overflow.


There is nothing difficult about this job unless the brake fluid hasn't been touched in years then you will be faced with seized nipples !
