Review on 🔧 GOOFIT 12mm Rear Hydraulic Caliper Brake Master Cylinder Assy: Ideal Replacement for 70cc - 250cc Quad Dirt Bikes, ATVs, Buggies & Motorcycles by Dean Love

I installed this caliper on my Apollo DB-X18 125cc off-road bike and let me tell you. it was a PAIN in my back. First, the hole in the bracket that the rear axle has to fit through was too small, so I had to drill out and enlarge it. After I fixed this problem I had to make my own shim so the pressure was equal on both sides of the caliper or the pads would grind. Finally, the rear master cylinder did not line up with the mounting holes on my bike. No big deal, I just reused my old one, but to avoid a headache like mine, customize it and make sure it's accurate or you're in for a day's project. It also looks great and my friends think so too.
