| + | ====== 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. \\ | ||
