The Scooter Brake that Stopped the Experts!

Straight from the Official Monster Scooter Parts Dictionary: expert noun, EK-spurt

• 1. a person with special skills or knowledge in a particular field
• 2. ex (a has been), and spert (from "spurt" -a drip under pressure)

Here at Monster Scooter Parts we have a whole warehouse filled with the miscellaneous odds and ends that every scooter owner sooner or later needs to keep on scootin' in style. We have tires and chargers and gaskets and batteries. Look in the corner and you will discover seat cushions and clutches, transmissions and throttle cables, all piled up to the ceiling in a neat and orderly fashion. Need a new electric widget harness? Widget parts; Aisle 7, Shelf B-14. In the market for a replacement gonculator assembly for a 1973 Pasta Motors Parmesan? Look on Rack 420, right above the custom chrome wine bottle holders. Having such a large and diverse inventory as we do, it really shouldn't come as any surprise when every once in a great while something comes across the desk that totally stumps us as to the whats, the whys and the wherefores of its origin. Here is a good example; a genuine "Internal Expanding Rear Brake Drum Assembly-90 mm". Frankly, I have never before seen an internal expansion drum brake assembly on a scooter. All of the small scooter brake units that I have seen use brake shoes that contract or clamp-down onto the brake drum, providing the braking pressure. This little brake unit's shoes expand outwards to grip the inside of the drum. Scooter parts are not usually very complicated pieces of engineering, and most generic parts will (more often than not) fit a multiplicity of scooter makes and models. Consider the ubiquitous 50cc 4-Stroke GY6 139QMB engine, a classic little power-house providing the putt-putt for millions of scooters around the world. It's a pretty safe bet that most any part for this engine will work on dozens of different manufacturers' scooters. And then there is this little mystery brake that defies all of our collective expertise. Lettering on the outside of the housing proclaims this is a "Servo Brake" from Xun Lin Brake. But try as we "experts" may, no one here at MSP can say for certain just what scooter models these brakes fit. It isn't the right brake for a Baja Doodle Bug nor is it anything made by Razor. I think it may be for an electric bike, but my wife tells me that thinking is just what gets me into trouble. The brake passes from expert to expert. Heads get scratched and chins get stroked. We hold it up to view like Hamlet with poor Yorick's skull, all the while trying to look more thoughtful than confused. Perhaps this esoteric mechanical marvel is the long-lost missing part that you need to get your scooter or ebike up and running again. Or maybe this is just what you were looking for to complete that home-built custom project in your garage. We have a few of these brake assemblies in both 90 mm and 100 mm sizes, and they are priced right at $9.99 per unit. Here's the links to see these two brake units:

• Internal Expanding Rear Brake Drum Assembly-90 mm
• Internal Expanding Rear Brake Drum Assembly-100 mm

OK; I confess, I made up the bit about the 1973 Pasta Motors Parmesan. They never came with custom chrome wine bottle holders. http://www.monsterscooterparts.com/
