No worries. I figure this kinda stuff is bound to happen when doing jobs like these for fun. It's all good.
Now, I have a related question: how does one clean up the brake line? Air pressure? Brake fluid? Since I'm getting new cylinder and already got calipers, might as well make sure the whole brake assembly is clean.

Ok. I guess I have no other option besides ordering a new master cylinder then. Thanks for your help.

I noticed that part, but didn't really think that's what it was there for. But tried doing it and the piston went a little further in, but still not far enough. I can get most of it into the cylinder (up to the middle of the second rubber seal - without the seal), but then it gets stuck again. I made a video trying to show what's going on. I was about to buy a master cylinder ( Brake Handle w/ Master Cylinder (PartsProUSA) - that was the only one I could find that matches my bike and has a mirror thread), but that one is $51. I'd rather buy one of these Hydraulic Brake Repair Kit if I can get away with it. What do you guys think? Should a rebuild kit be enough? Why am not being able to reinsert the piston back into the cylinder? |

I'm trying to get my front brakes on my 150cc Tank Classic Scooter to work, but am at a point where I need a second opinion before going any further. A while ago I had a leak at the front brake caliper that soaked both brake pads with brake fluid. Bought new pads and a new caliper, but for whatever reason never really bothered to put them back on the bike. Left brake hose (caliper end) with a plastic bag wrapped around it and brake fluid reservoir open to the surroundings without any brake fluid (which I believe it was what caused all my - following - issues) Finally decided to put everything back together. After having the pads in the caliper and the caliper around the rotor with the brake hose attached to it, it was time for some brake fluid pouring. After unscrewing the bleed valve, went to squeeze the brake lever when, for my surprise, it was kinda stuck. Put a little bit more pressure into it and bam, the piston went all the way in and it wouldn't come back out, leaving me with a loose brake lever. So, here I go remove the master cylinder and open it up. Right now, there's where the issue lays - the master cylinder. I removed it from the handle bars and disassembled it (removed brake lever, brake light switch and cylinder piston). Checked everything for damage, but couldn't really find anything. The problem is, when trying to put it back inside, the piston is having some resistance - it feels like metal sticking to metal - which I'm not sure if it's the way is supposed to be (from videos on youtube). My question is: how hard is it to reinsert the piston back into the master cylinder? I also have to mention the fact that I did bang the piston from the spring side in order to remove it from the cylinder. Could that have deformed the piston itself? Or maybe damaged the inner surface of the cylinder? Here's a picture of what I have: Image on Dropbox of Master CylinderI appreciate your input. This will help me decide if I should buy a rebuild kit only, or if the whole master cylinder assembly needs to be replaced. Keep on riding/tweaking. |

Hi all,
Hope everybody is enjoying their saturday like I am, fixing my scooter!
This is Joao Paulo, I'm originally from Brazil (world cup, yeah!!), but have been living in Reno,NV for about 6 and 1/2 years now. I have a 150cc Tank Classic scooter and right now I am having some issues with my front brake. So you can expect I'll be posting at the garage section pretty soon.
Just wanted to stop by and introduce myself and meet some of you guys!
Keep on riding/tweaking!
