Cheers fella . I didn't google anything I'm crap with computers and all that stuff . To be honest didn't even think you would get that info . I live in the dark ages ... I'll check hoses and stuff . The brake lights are working but I'm unsure if one has been changed . The car has just been for it's mot .
