Mechanical rear-brake module

Arrma Kraton 6S EXB Roller · ARA106053

This adds a separate servo-operated rear brake alongside the normal motor brake. It gives you independent rear braking for handbrake-style turns, provided the radio has a spare control channel and the brake is adjusted to release freely.

ARRMA documents this option for this edition. Check the installed parts before ordering.

Installation notes

  • Choose this module for separately controlled rear braking and handbrake-style turns. It supplements the ESC motor brake rather than replacing it.
  • The kit includes an assembled module with S650 servo installed, 23T/24T/25T horn choices, a 150mm servo extension and mounting screws. A second brake servo is not required.
  • A usable third radio channel is required. Check the installed transmitter, receiver, channel allocation, servo supply and travel before ordering; a channel already committed to another function is not spare.
  • Follow the supplied mounting instructions, keep wiring clear of moving parts and set endpoints so the brake releases freely. Check normal braking and steering before driving.
  • The roller requires a suitable separately chosen radio/electronics build. There is no factory-installed transmitter or receiver to assume.
