How To Rebuild your ATV Master Cylinder
Carefully remove the twin Phillips head screws that hold the cap on and set the cover along with the diaphragm plate and rubber diaphragm to the side for now. Be sure the handlebar is positioned so the master cylinder is as level as possible to avoid spills.Using a couple of paper towels or disposable shop rag dry up the fluid in the master cylinder until the majority of the old fluid is gone. Be very cautious as to where you dispose of these rags after they have soaked in the fluid. If these rub up against some metal or painted surfaces, things will start to corrode.
To gain better access to the master cylinder for cleaning, remove the master cylinder from the handlebar by removing the two 8mm bolts that keep it in place.
Step Three
Loosen the 10mm banjo bolt that holds the brake line to the master cylinder. Be sure to not lose the copper washers as you will need them once you start to put the system back together. You may want to wrap the line with an old shop rag just below the bolt as fluid remaining in the line could leak out. Loosen the two 8mm bolts that hold the brake master cylinder to the bars and pull the master cylinder from the bars.
Step Four
Remove the brake lever from the master cylinder by removing a single pivot bolt, which is held in by a locking nut. This will
allow you to see the plunger and rubber boot that covers the plunger. There is a snap ring that holds the plunger in place and you will need long thin snap ring bits to get down inside the cast body of the master cylinder to get it out. The old plunger, spring and seals should simply pull out of the master cylinder. You will also want to remove the black silicone seal inside the master cylinder to get any debris out from under it.
Step Five
Once everything is removed you are ready to completely clean the master cylinder. After it is prepped for the new plunger, spring and seals add a little coating of brake fluid to the seals. This should help the reinstall of the new plunger and spring.
