Fitment FAQ
Will this part fit my specific model and year?
This brake assembly is intended for Vehicle Type; Displacement Range; Common Brands; ATVs / Quads; 50cc, 70cc, 90cc, 110cc, 125cc; TaoTao, Coolster, Mountopz, Peace Sports; Dirt Bikes / Pit Bikes. Key physical/spec details from the product data include 50cc, 125cc, 70cc. Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?
Yes. If your original part has a stamped OEM or manufacturer number, match that number first before ordering. 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, 70cc. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
I've got a very old 4x4 that has a single brake on the transmission. There are no parts available for a 60 year old machine. This universal master cylinder and brake pad assembly looks well made and includes an extra set of pads. I'm planning to fabricate brackets and retrofit this new unit for use on my old 4x4. It's actually a bit more heavy duty than the old one that I will replace. Glad I found this listing. Looking forward to hitting the trails again.
