I BAUGHT A #))EX AND I KNOW NOTHING ABOUT IT I BAUGHT IT FOR $200 IT HAD BAD BEARINGS SHOCKS BUT GOOD FRAME, MOTORAND PLASTICS I PUT ALL RACING STUFF ON IT I HAVE NEVER HAD REAR BRAKES ON IT. I FINALLY PURCHASED SOME AND MY E-BRAK BLOCK OFF PLATE LEAKS. DOES IT NEED A GASKET? WHAT SHOULD I DO ???

 

the cliper should not leak because of the block off plate try new seals and hone the cylinder with a brake hone. or buy new caliper.
