Hi all,

Last weekend I wanted to see what was wrong with the speedometer. Turned out it is the speedo-gear, there is my trouble. I used a electric screwdriver to turn the cable and i could see that the speedometer was indicating speed and the odometer started counting mileage. Next thing I tried to turn the wheel to check if that speedo-gear turns/rotates, but it didn't. Trying to turn the wheel (with my hands) I noticed that the Brake pads were a bit stuck and so I removed the brake caliper and then the brake pads inside. I pumped the brake leaver quickly and the piston started to come out of the caliper. It was dirty and quite stuck. I cleaned it with "Brake caliper cleaner spray", but my guess is that gasoline(petrol) would have done the same thing(cheaper method). On the clean piston I applied some brake oil/fluid and pressed it back in using a method seen on youtube(link bellow). After that i removed the old brake fluid from the system and replaced it with new one. I pumped out the piston again and repeated 2 or 3 times this procedure until the piston got loose. Brakes work fine now.
Still, the question remains: Can a speedo-gear be fixed, repaired, or should I buy a new one? And what is your opinion on Iridium NGK spark-plugs?

I got my info from these links, hope they are useful:
