The 4-5/16" (110 mm) brake disc for GOTRAX electric scooters is commonly called a rotor. Our replacement steel brake disc is the same as the one on a brand-new GLX V2 straight from the GOTRAX factory. This brake rotor for the GOTRAX uses five 7/32" (5 mm) mounting holes spaced 1" (25.4 mm) apart.
This brake disc is compatible with a variety of GOTRAX scooters including the Apex, Apex XL, GXL V2, XR Elite, and XR Ultra.
