Hi Nico,
nontheless you can use the axes-method to display your preferred labels. The
colorbar has its axes as attribute 'ax' (see also my small example below):
cb.ax.set_yticklabels((r'$-\pi$', '0', r'$\pi$'))
Kind regards,
Matthias

import numpy as np
ax = plt.axes()
plt.imshow(np.reshape(np.pi*np.arange(-2, 3, 0.5), (2, 5)))
cb = plt.colorbar()
cb.set_ticks((-np.pi, 0.0, np.pi))
cb.ax.set_yticklabels((r'$-\pi$', '0', r'$\pi$'))
plt.show()
