If you're looking at how to change your dirt bike brake fluid or you have air in the system this tool being reviews will help. The bottom line is

air in your dirt bike brakes is hard to get out. The easiest way of knowing you have air in the system when your brakes feel spongy which means it makes stopping hard, or your caliper won't retract correctly which burns up your rotors and pads. Personally I have had both situations happen. Once after putting on a fresh set of pads and rotors, so I was out over $130.
How To Fix Issue:
Fixing this issue is pretty easy if you have the correct tools. I used the
Motion Pro Brake Bleeder
. It's simple to use, and works better than the old fashion way. The main advantage you get is you can visualize air exiting the system. There for you know when your system is air free.
How It Works:
Hook up the
Motion Pro Brake Bleeder
short hose to your dirt bike's brake bleeder nipple insuring the arrow on the valve is pointing away from the nipple. Make sure the metal retaining hose clip is attached on the pressure side between the check valve and bleeder nipple. Then loosen the brake bleeding nipple and pump your brakes as per manual. The silver metal valve on this tool has a built in check valve which won't allow air to enter your brake system. Once you're happy your fluid is changed and the air is out of the system tighten up your bleed nipple and remove the tool.
Conclusion:
Its good maintenance practice to change out your brake fluid at least once a year or after you boil the fluid squeaking is a good sign of this. Personally I used to bleed my brakes the traditional way until air in the system cost me money. The aspect that amazed me most was how many tiny air bubbles came out on a system I felt was purged. Now I use this tool since at a cost of

it's cheaper than pads and rotors.
Tip-Make sure you continue to fill your brake reservoir when bleeding your brake system to keep air from entering from the master cylinder. Also double check which type of fluid your system uses.
