Replacing

If you also have a dirt bike in use,

Replace with a new one band drum brake is a great decision.

Kids ride theirs so much, Brake can quickly become damaged,

and replacing them with new ones can make children's riding more enjoyable.

Thought it was functional until my son tried it out it won't stop his bike at all, was really trying to not return it the holes for the screws are too small or too big and was missing 2 screws tried to hold out to find the screws on my son's old set but cantUpdate: fixed the problem and they are fully functioning again

This will work as a replacement for your mx350 brake however it will wear out very fast. I do not recommend this if the bike is modified for speed for the rider is heavier than a small child

These fit right on the frame of an old Chinese scooter thing that I had laying around in the back of a barn. I collect frames of various types, and this was one of them. They will certainly stop a scooter, but if you weigh more than 100 pounds, you'll want front brakes too. These will overheat very quickly otherwise. You'll know when they overheat, considering they won't stop.If you use these in conjunction with front brakes (I used discs) they work a lot better. They are fine on their own if you put them on a kids' scooter with a light kid riding it. That means two things. One, it doesn't need to stop much weight. Two, a kids' scooter isn't going to go very fast. Both things help this work properly. If both of those things aren't true for your build, then add front brakes as well.
