Hello, I have a Margay kart with an Ital Braking system. Whenever I push the brake peddle, fluid leaks from the master cylinder plug. I’m not sure if rebuilding the master cylinder will fix the problem or not, or if the plug or even the whole master cylinder went bad. Any help is appreciated.
If my memory severs my right, there should be a metal washer under the bleeder plug. The washer could be missing. If that’s not the case, try a rubber O-ring. Carefully make sure there is no debris trapped under the bleed screw.
Thanks Tony, there is a washer, but I’ll definitely try the O-ring. I forgot to mention, but the screw never sits tight, so I’m thinking it could be stripped threads, not sure if it is the plug or if it is the threads on the actual master cylinder.
Do NOT use an O-ring under the plug. It is not designed for an O-ring and may not hold the pressure. You can’t tighten the plug down properly with an O-ring and it could vibrate loose. Anyone who is doing this is living on borrowed time.
