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 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 50cc, 125cc, 110cc. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
