The Monobrake is a low-slung search and recovery utility vehicle capable of either travelling along monorail tunnels or, by using its front-mounted cahelium strengthened telescopic arm. The telescopic arm can be attached to an overhead monorail. A safety hood behind the driver/passenger seating serves as a barrier from the extreme temperatures of the jet engine.

Due to its low height, the Monobrake can drive in a monorail tunnel and have a train pass over it without incident.

The vehicle appeared in The Perils of Penelope, is glimpsed in the vehicle hangar in Cry Wolf and can be seen in Pod 1 in Security Hazard.

Only two cutaways of the Monobrake are known to exist. The first featured in Redan Thunderbirds Comics, and the other appeared in the Haynes Thunderbirds manual. Both cross-sections were illustrated by Graham Bleathman.
