Key physical/spec details from the product data include Axle Diameter: 15mm (0.59"), 15mm, 107cc. Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?

For this brake assembly, also compare the caliper bolt spacing, brake hose length, master-cylinder bore, lever side, banjo fitting angle, drum/hub dimensions, and handlebar diameter. This is especially important for TaoTao/SSR models because similar model names can use different parts by year or trim.
What models or situations does this part not fit?
Do not order this brake assembly for machines outside the listed compatibility, or for units with different caliper spacing, hose routing, lever/master-cylinder setup, drum/hub dimensions, or handlebar diameter. Do not rely only on the model name or engine size.
What should I check before ordering?
Before ordering, compare your original part with the photos and check the caliper bolt spacing, brake hose length, master-cylinder bore, lever side, banjo fitting angle, drum/hub dimensions, and handlebar diameter. Recheck listed specs such as Axle Diameter: 15mm (0.59"), 15mm, 107cc. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
This fit my 2005 even though it is a single cylinder rather than a dual like that factory one. It is also a in master reservoir, rather than a remote reservoir so it ended up being a bit easier to mount. I think the mount could be a bit more heavy duty for 5 stars but for what its for the mount is perfectly sufficient.
Works great. Awsome product for the price.
Much cheaper than retail store,will recommend to friends.
Fits great on ssr 110, will need to remove rear axil to fit new bracket
