LOSI PROMOTO-MX 1/4 Motorcycle Front Brake Caliper by GPM MX035  [MX035]

Front brake caliper for PROMOTO-MX

This GPM MX035 front brake caliper is an RC-scale replacement part produced for LOSI PROMOTO-MX 1/4 motorcycle models, made from aluminum 7075 for structural stability in braking assemblies. The text below focuses on fit, installation considerations, and its role in brake setup without implying real vehicle use.

The caliper replaces the stock plastic unit to provide a firmer mounting point for the brake interface and threaded hardware supplied. It interfaces with the existing brake actuating linkage and brake disk on the specified PROMOTO-MX RTR kits, maintaining scale fit where the original mounting pattern is preserved.

For hobbyists working on the listed PROMOTO-MX variants, this caliper serves as a direct aftermarket metal replacement that aids in brake feel consistency and hardware retention; use the included fasteners and verify alignment during reassembly.
