PROMOTO-MX 1/4 Rear Caliper 7075 Aluminum MX036 by GPM  [MX036]

7075 Rear Caliper for PROMOTO-MX

This rear caliper is a replacement part for 1/4 PROMOTO-MX motorcycles, identified as MX036. Machined from 7075 aluminium, it gives a firmer mounting point compared with stock plastic parts to help maintain consistent pad alignment under braking and during regular track use.

The unit is designed as a durable, serviceable caliper that mates with the bike's existing brake linkage and mounting pattern. It is intended for hobbyists seeking repeatable brake feel and easier maintenance rather than changing brake fundamentals.

Fitment is performed at the hobby bench with standard RC tools; verify screw torque, rotor clearance, and pad alignment during installation. Inspect wear surfaces and fasteners at routine intervals and correct runout after first fitting.
