Have you adjusted them ?

Hello there.were the back cylinders sized due to lack of use?I.e is the flexible pipe feeding the rear axle not letting sufficient fluid through..just a thought..rob

The two above answers are likely causes, but also, what about the condition of the brake drums?

Has it failed on mot on the foot brake test or the handbrake test?

Check to make sure all the springs are in good condition and fitted correctly during the rebuild, make sure any excess brake fluid from the faulty cylinders has been cleaned away from the drum and other components.

Lastly, I would bleed and adjust the brakes again.
