+====== An Exercise in Bleeding the Brake System ======
 The test subject is a brake lever and master cylinder from a 95 Kawasaki but the process is the same for a Sportster. \\
 ====== Clean All Old Brake Fluid Out of the M/C ======
-Make sure the master cylinder has new and clean brake fluid in it. \\
+Before replacing fluid or bleeding the air from your M/C, make sure the master cylinder has new and clean brake fluid in it. \\
 Remove (soak up) any old fluid with a rag or paper towel and wipe down the inside of the M/C. \\
+Then add the proper fluid to the fill line. \\
+If in doubt about what type fluid to use, refer to your FSM and it's also stamped on the cover. \\
+See more information here about [[techtalk:ref:wheels03#brake_fluid|Brake Fluid]] in the REF section of the Sportsterpedia. \\

+You can see the difference in the color of the old and new brake fluid in the reservoir. \\
+You don't want to send more old brake fluid in the system while you are working. \\

+====== Test the M/C ======
+**For a pressure squirt**: \\
+With new fluid in the M/C, before attempting to move fluid or bleed the air, lightly squeeze the lever or pedal. \\
+Watch for a spurt of fluid from the hole in the bottom. \\
+This shows the seals are operating properly. \\
+If you squeeze / push too hard with the cap off, the spurt will be higher and may come out of the M/C onto the bike parts. \\
+If using DOT 5 fluid, this is a simple matter of cleanup with a rag. \\
+If using DOT3,4 or 5.1 then it needs to be hosed off with water immediately as these type fluids will eat your paint. \\

+**For air bubbles**: \\
+With the cap off, tickle the lever / pedal and check for air bubbles to come up inside the M/C. \\
+If you see any bubbles, before sending these down the brake line, continue to tickle until they are no longer created. \\

+====== How Air Bubbles Move ======
+Here's a short video on how the air moves as the lever is tickled. \\
