Got a new brake servo on order for this,(hissing noise inside car around the push rod)the hose and valve are ok, autodata says 3.3 hours to fit, anyone knowof any problems doing this? My main concern is when i drove it it was very slow to change gear up or down. If i held my foot on the brake to stop hissing noise, gear change up seemed to be better. Could this servo fault affect gearchange or is in my head.
Thanks
Tommy
