solid brake pedal

[thebluepearl]

had this on my hdi after i flushed the oil before the oil change
i fixed mine by spraying a little Plus gas into the pump outlet which worked a treat

i put mine down to sticky vains in the vac pump as it used to come and go normaly at low rpm
its not done it since

Both times mine has done this is at low rpm leaving work/home probably 10 seconds after starting the car and moving off
