Before disassembly, the inside of the boot is full of fluid
When I removed the boot, fluid was dripping everywhere. It’s quite rare to have this much accumulated. I’m a bit curious about what’s inside
You can see a white object in the image, which is a substance hardened like tartar Thinking about it, it’s possible that at some point it got caught slightly at the lip.
If the fluid hasn’t been changed in years or if it’s a long-term non-running vehicle, always check the brake system.
Comparing the brake side overhaul kit, the cup is indeed swollen and the umbrella has become droopy. It feels like we discovered it at just the right time.
The structure is very simple, so the cleaning process goes smoothly.
I think it’s best to check the dimensions between old and new just to be safe.
Since I don’t overhaul Nissin radial masters very often, it took a bit of time to gather information. These old and new repair parts are different so if you forget to remember that, it could get dangerous.
That’s how I’m learning something new every day.
I’ll replace the fluid tank as well
The fluid tank was also getting all dried out and looked like it might crack, so I replaced it with a new smoke-tinted one.
Both the brake and clutch have a firm feel now, so they operate really nicely.
