Hello, I bought some brake / clutch lining material for my gy6150 scoot. The process is glue & bake. CURIOUS... if anyone: 1.) Knows if the "drum brake" / "clutch lining" material that comes with our scoots has "ASBESTOS" in it  ? 2.) If "ASBESTOS" is in the brake and clutch lining........does anyone know a safe way to remove the brake & clutch lining material. I would really like to try this "high temp - higher performance" drum brake & clutch material for performance and lasting capabilities. The "ASBESTOS" possibility and material removal is the hurdle at this time. Thanks up front for any help / info on this. |

The way we did it in the truck garage I worked at (41 years) was to use a spray bottle, set to mist, filled with water. Spray it down so all the dust is wet and won't blow in the air. Then take a few rags and wipe everything off.

Thanks. The existing material on the clutch and brakes is about an 1/8' +. Any suggestions on the way to get it off - sanding, scrapers, chemical, bench grinder, etc |

I had to do something similar once (one of the don't ask projects given to the newbie when I was a mechanic in the Army). After the third drum, I found the easiest way for me was to use a grinder to cut grooves across the face every 2", then use a chisel to push out the 2" strips, then clean up the leftovers. Most of the 2" strips pounded out clean, a few I had to spend a bit cleaning up. Breather mask and eye protection are a must, and spray down all dust as mentioned above.
Turns out the Sgt had OKd a replacement that was not USArmy approved, and we had to hurry to get things back to GI before an inspection.

You're removing the existing material and then relining the brakes and clutch? I didn't even know you could do that. Now I'm extremely curious. Is it a kit or what? Point me some where that I can get more info. Not that i'm thinking of doing it but now I have to know.

Hello, I figured since there are businesses that reline brakes and clutches (glue and rivet both - I believe) that I might give it a try. The item I chose for the lining is ( HIGH STRENGTH - because its bendable / flexable - for the clutch and rear drum brakes) at : www.mcmaster.com/#brake-lining/=ryeglpThe company is : McMaster-carr -- web home page is: www.mcmaster.com/#They sell the glue too but I cant remember what glue I went with at this moment...but they have it. REMEMBER --- THIS IS SOMETHING I AM ATTEMPTING. I spoke with a local brake and clutch rebuilding shop and they reline brakes and clutches PROFESSIONALLY. This is my first attempt. |

My brother worked at that occupation and it is a high risk occupation for mesothelioma. All it takes is one stray fiber to give you cancer. You can rest easy that most Chinese OEM brake products contain asbestos.

Well, the brake lining has been chiseled off and the remaing material sanded off (wet sanding on the last little bit).
Wore a disposable "chemical" face mask - covers face and nose. Should be O.K. for keeping out larger contaminants since it is design for chemicals / vapors.
Tomorrow - I will glue the new ( NON - Asbestos) material on.
I am guessing that because of the sanding down of any existing material and glue that the brakes can only be relined 2 times and maybe three at the most.
One this is for sure. From here on out I will just take my brakes and clutch to a shop and have them do it - I am sure they also will only be able to reline them 2 or 3 times tops also. Only thing is, I don't know if they will let me pick / supply the material I want... Main thing is NON - Asbestos.
Anyway, When I get the brakes finished and test I will re-post how it works.
******* Thanks to everyone with their advice.

Just remember that what you sweep up and dust off in the shop will for some time unless you used a vacume cabinet potentially be contaminated with asbestos as will be your clothing, laundry and bathroom. Any dust that you collected along with the equipment you used to create the dust will now be hazerdous waste in many areas which I don't understand fully myself since brake pads and shoes are constantly shedding asbestos into the air on the roadways as they get ground away during use. When my brother worked in the brake relining industry there were protocals for dealing with the waste along with the coveralls, gloves, boot covers, headgear and respirators they had to wear at the plant.
After he went through the two weeks training and got to review the safety protocals along with the risks he immediately started looking for another job.
