I live in Uganda so have not driven my E Type for two years for reasons we ALL know about. Drove her last week down to a winter storage at a colleagues garage in Sturminster Newton and I appear to have a brake servo issue. Brake pedal travel too much! Press the brake with engine off and we can hear a hiss from I assume the pneumatic side of the servo. Is there an E Type/brake specialist in the area of Sturminster Newton who can help to ascertain the issue?
