i gota an 02 400ex and when i press down on the rear brakes the lever just sticks down and doesnt come up. you have to pull the lever up with your foot like your shifting or something im not sure

 

Is the spring that pulls the lever up gone?

 

no the spring in definately there, it was the first thing i checked, and the fluid is completly full

 

I had that same problem with mine last spring. Try taking the lever off and clean it well and throw some lube on it. I would scrub it good with a wire brush and then hopefully it'll be all good.

 

so just take out the lever and scrub it really well and maybe put some chain lube or wd40 on it?

 

yeah I cleaned up the whole thing quite a bit on the shaft and the brake lever. Then when i slid it back on the four wheeler i worked it up and down alot with the spring off to make sure it wasn't sticking.

 

k thanks ill have to try that this weekend

 

now theres another problem...i got the piston, the spring, and the pin pulled off the brake lever but cant seem to get it out, dunno if its bent or the dust seals are holding it in there and am not sure how to remove those

 

MY 400S LEVER WAS COMPLETLEY FROZEN. TAKE ALL THE STUFF OFF TO WHERE ITS ONLY THE LEVER THEN SPRAY WD40 BEHIND AND IN FRONT AND JUST WORK IT UP AND DOWN 10 OR SO TIMES THEN PUT MORE WD THEN A FEW MORE TIMES AND IT WILL COME FREE. MINE DIDNT COME OUT THE HOLE EITHER TO CLEAN IT OFF BUT IT HASNT FROZEN UP YET.

 

Just a suggestion Randall, take off your CAP lock.
