How to replace and adjust the rear brakes on a 150 or 50 cc GY6 Chinese scooter 

That's awesome! Thanks for watching, and remember to share the videos with your scooter friends. :)

Yeah a few people noticed that. It probably is a crack. I sold that scooter a few years ago. I hope it didn't break.

thanks for that info.

appreciated!

Start by removing that rear wheel so you can inspect the brake shoes. If they're close to worn out, or if they're contaminated with any kind of oil, replace them. Clean the brakes with water or brake parts cleaner. Do not use compressed air (you'll breathe in all the dust), and do not get brake parts cleaner on the friction material on the shoes. Apply a TINY amount of grease to moving parts, like where the shoes contact the backing plate. Be very careful not to get grease on the braking surface.

Yes, you can, but it will be a lot of work. The charging system is a bit different, so you'll have to do some wiring, plus it might not mount up to the frame the same way. I recommend just getting a different Chinese scooter. The 50 to 150cc swaps are common with the Honda Ruckus scooter, because It's good quality and not available as a 150. Nobody swaps motors on the Chinese ones because it just isn't worth it.

+Paul Shpakov Thank you

Yes. The cool thing about Chinese scooters is the engine is almost exactly the same in all of them.

It sounds like you could use some new brake shoes. I've tried sanding brakes before, but it usually doesn't work. Also make sure you clean all the brake hardware, and use brake parts cleaner or alcohol on the brake drum. You'll need a tiny bit of grease where the shoes pivot, but make sure you don't get any on the braking surface.

yeah like BMW cars...

There are a many places online. Here are a few: www.partsforscooters.com/ www.powersportsmax.com www.vmcchineseparts.com/ www.amazon.com/ www.ebay.com/ Remove your old pads and measure them before ordering. Make sure they look the same as the new parts and have the same dimensions.

Your rear brake is probably too tight and dragging the whole time. Put the scooter on the center stand and try to turn the rear wheel by hand. If it's hard to turn, the brake is probably too tight.

You now have to have your local dealers to correct your mistake!

Could be wheel bearings are bad.

Check to make sure the brake pads move out toward the drum when the wheel is off. Also check for contamination. The pads and drum must be clean and dry with no oil or grease on them.

@@LabCoatPaul I have already cleaned it, maybe they don't move out far enough.

I can't remember if they're the same or not. Spacers will be different on every scooter. You might not even have any. The most important thing is to put them back where they were.

The rear brake shoes will be different for every scooter. You'll need to take some measurements of your brake pads and find the same ones online.

The center stand on my scooter would hit the ground on turns, so I cut it off.

I have a 150 Chinese scooter which I just got, brand new 2017 model and I don't even lean mine over that much to come close to hitting my center stand on the ground. I am just curious as to what kind of tires you are riding on to feel that comfortable to lean that far over on yours

They're just the crappy stock tires. I really didn't lean that far. That stupid center stand was just too low.

Well explained very much appreciated Cheers peeps 😆

yup! I used to live in Iowa City a few years ago.

Paul Shpakov Nice! I'm from Waterloo.

The speedometer is mechanical not electrical it's just a cable that spins, it's the cable in the front wheel just unscrew it and follow the cable and it should be attached to the speedometer just unscrew that and vice versa with your new cable

any regular bearing grease will be fine.

Yes, there are many different brake pads. With Chinese scooters, it's a bit trickier to find the right part, because they aren't organized and provided by the manufacturer. You have to search partsforscooters.com or ebay, or your online scooter parts dealer of choice, and find pads that look like yours and hopefully have some matching measurements.

That might be normal. Many motorcycles have only one low beam come on. For example, the Honda Ruckus and the Yamaha Tmax500 are both like that. If you prefer both lights to be on for low beams, you can run a jumper from one low beam to the other and you'll have both of them come on.

+Samuel Marchán Fernández Mine has an oxygen sensor. Most scooters don't have that.

Thanks! Yup, that's a Chinese scooter. :)

Yup. Chinese scooters are not very good quality.

Oooohhhh!~ Chinese piece of shit! It looks like you're right! I hope it doesn't fall apart any time soon! wow... thank you though!

Paul Shpakov Yeah, that guy saved your life.

Paul Shpakov No problem man! A new motor only costs $300. Thats the good thing about these scoots!

Paul Shpakov did it ever snap?

Paul Shpakov did you fix it. ?

It's like a puzzle. You'll figure it out! On my scooter, the spacer was between the wheel and muffler bracket.

That's a tricky question to answer. These scooters use several different sizes of metric bolts. The smaller ones that take a 10mm wrench are M6x1.0. The bigger ones on the muffler are probably M8x1.25 or M10x1.5. The "M" stands for metric, the number after the M is the diameter of the bolt in millimeters (an M6 has a 6mm diameter shaft), and the last number is distance between threads (thread pitch). Basically, if you're missing the little ones, get M6x1.0 from the store, if you're missing the bigger ones, get M8x1.25 or M10x1.5.

elso alvarez First, make sure you have enough air pressure in the tire. With 2 people, you probably want about 45psi. Also check the bolts to make sure everything is tight.

thanks i will check that but i will also check the bushing i think i found it not balance ill try to change it but thanls for your help i appreciate it a lot

Yes, all the Chinese scooters use a similar GY6 engine, so yours will be the same.

A screeching sound means there might be something wrong with the belt. Remove the transmission cover on the left side and look inside.

If your brake shoes are worn, you'll get a rear brake that is weak or does not work. The brake light would still work.

I did this video in the winter, so my other option was to freeze while working on the brakes. I chose to stay warm.

Yeah indoor when cold 👍

+Zachary Butler www.partsforscooters.com is one of the best.

taotao parts direct, lots of places on the net..

You figure this out? Having the same issue on a tao tao pmx 150. Same size brake drum but tire drum housing doesn't go all the way back on.
