Hi all,
Car is 08 octavia 1.9tdi
Noticed today with the engine on the first 2 times I press the brake pedal it feels soft, on the 3rd push it feels fine and back to normal.
But leave it for a few seconds and it's back to being soft and goes straight to the floor.
With engine off the pedal becomes hard and stays hard.
Checked around the calipers and under the car and no leaks visible.
Brake fluid is full.
Any ideas?
Brake vacuum pump leak maybe?
