Hi guys ive had problems with the brakes on my fiesta. I had a run in my Escort RS the other day and decided to turn off ignition and hit brakes as the servo wouldnt be working. As I suspected my fiesta brakes while runnin the same way my Rs did while turned off. You know the jump on the pedal to stop stuff

so was wondering if my fiesta could be needing a servo? or does anyone know where else to look before the servo? vacuum pipe dont seem clogged or anything so took it to be servo but again dont want to go changing it if it aint that

any help will be appreciated guys cheers
