LOSI Promoto-MX Rear Brake Caliper (Red Anodized Aluminum) - JR-LMX06-RD by Jazrider  [JR-LMX06-RD]

Rear Brake Caliper — Promoto-MX Fitment

This red anodized aluminum rear caliper is an RC-scale replacement part designed for LOSI Promoto-MX motorcycle models. It provides a direct spare for the rear braking assembly on Promoto-MX chassis variants and is supplied by JAZRIDER under model JR-LMX06-RD.

Built for straightforward service, the aluminum body gives a firm mounting for brake pads and linkages while the anodized coating helps reduce surface wear from handling and dirt common to off-road riding.

Installation and tuning notes: fitment assumes Promoto-MX rear mounting points and brake linkage layout remain unchanged, so installation is typically a bolt-on swap using your original hardware. During setup, verify pad alignment and lever travel, and make small adjustments to braking geometry to suit your existing configuration.

Use cases: replace worn or damaged stock parts, keep a spare for maintenance intervals, or retain consistent braking performance after chassis changes; intended for RC motorcycle use on dirt circuits.
