LOSI PROMOTO-MX Front Brake Caliper by GPM MX2035  [MX2035]

Front brake caliper for PROMOTO-MX

This is an RC-scale front brake caliper produced for LOSI PROMOTO-MX platforms by GPM, intended as a replacement or upgrade component for 1/4-scale PROMOTO-MX motorcycle models. The unit is presented as a completed caliper assembly with associated mounting hardware and pads, designed for hobby use on RC dirt motorcycle chassis rather than any full-size vehicle applications.

The article focuses on compatibility, installation context, and tuning role: the caliper replaces the stock front brake assembly on specified LOSI PROMOTO-MX RTR models, provides a durable 7075 aluminum body to resist wear from hobby use, and serves as part of braking system maintenance or incremental performance tuning for handling and feel on RC dirt tracks.

For builders and tuners working on LOSI PROMOTO-MX 1/4-scale dirt motorcycles, this caliper assembly supplies a direct-replacement brake option with included hardware and pads; use it as part of routine maintenance or to refine braking response on hobby tracks.
