I have FJ62 with front drumbrake. Somedays ago, I catched problem with brake master cylinder. I completely disassempled master cylinder and found that piston's rubber cup is torn. So, I asked to toyota and they said not only repair kit(04493-60130) but master cylinder(47201-60330) was discontinued. It has 1 1/16" bore (how big diameter!) To figure out, I tried many things and finally gor US FJ62's brake master cylinder and installed. But it didn't operate well. That 7/8" bore of master cylinder is for front disc brake land cruiser. It operates always as sponge pedal although I did bleeding very well. It's very urgent to me... Is there any people who could help me ?
