Hi

I have an 05 Citroen C8 that has a problem with the brake pedal. When braking the pedal moves a short distance and starts to get firm, then starts moving again until its about 2/3rds its travel and works fine. This is every time and regardless of speed/load/temp etc. It's fine on a brake tester but has failed the mot on the pedal problem.

Anyone have any ideas please
