A vehicle brake transmission includes a housing unit, a motor assembly, and a speed reduction unit. The housing unit includes a ring gear disposed around a first axis. The motor assembly includes a motor, and a worm rod extending along a second axis perpendicular to the first axis. The speed reduction unit is disposed in the housing unit, and includes a driving member, a planet carrier, and a plurality of planet gears. The driving member includes a worm wheel meshing with the worm rod, and a sun gear centered at the first axis and meshing with the planet gears. The planet carrier includes an input shaft connected to a caliper device. The motor drives rotation of the worm shaft, the driving member, the planet gears, and the input shaft, so as to activate the caliper device.
