An often overlooked component of the average riders machine is the brake system.  Sure, it seems to be working properly, so if it's not broken, why fix it, right?  Wrong!  If you want optimum braking, and most importantly, for your own safety, the brake system needs to be inspected before every riding session and serviced regularly.

First,  check the pedal for free operation.  Be sure it returns freely, the linkage is tight, and all mounting hardware is secure. 

Second, inspect the master cylinder and fluid.  Be sure there's enough fluid, lines are in good shape and no leeks.  See what the fluid looks like.  If it's cloudy or dirty, it's time to change it.

Third,  check the line.  No abrasions, rubbing spots or stray loose sections of line.  

Forth, check the caliper, hanger and anchor assembly (if you have one).  Be sure there's enough material left on the pads.  If you installed new ones, don't forget to bed them before you race.
Look for leeks and free operation of the piston (s)  If you're running an anchor, be sure it is installed with a ny-lock nut, and secure it with Lock Tite or safety wire.  If it comes loose, it will take out shocks, disc, spokes, other riders or you, so check it every ride!  Check the hanger and if it's a floater, be sure it isn't worn where it hangs from the wheel spacer. This could cause it to drag, or hang up, and overheat the disc, and boil your fluid.  If you have a fixed hanger, be sure its fairly centered on the disc, and any hardware is secure.

Lastly, check the disc. for warping, cracks and wear.  Inspect the knock off nut or mounting hardware for tightness.

Your 1st step is to lightly spray your axle with WD-40 or some similar product and make sure it moves freely in the forks and wheel.  Next make sure both fork legs are the same distance down in the clamps.  After sliding the axle through the forks, wheel, and any spacers, lightly tap the end of the axle to make sure it is seated tightly against the wheel and opposite fork leg.  Tighten the pinch bolts under it if there are any.

Now comes the important part.
Loosen only the pinch bolts opposite the axle nut and standing over the top of the motorcycle push down on the handlebars several times to allow the fork leg that the pinch bolt are loose on to find the place on the axle that keeps the fork from binding.  Now tighten those pinch bolts again and check to make sure the axle nut is tight.  Spin the front wheel to make sure it turns freely, and go RACING knowing that your front forks are able to move up and down freely.  Good Luck!!!!!
