Whooshing noise, brake problem. Servo?

Post by BongoBarrow » Wed May 24, 2017 9:32 pm

Hello.

I've in intermittent brake problem. The brake pedal feels like abs has kicked in and after a judder, it sinks lower to the floor. Brakes still work although van pulls to the right.

However, I get a warning in the form of a whooshing sound from air vents. When I hear this I know the brakes are going to be funny.

Thought it could be air being sucked in to vacuum pipe to servo but no obvious split. If I pump brake when ignition is off, it does build pressure as expected before easing when ignition is on.

Any ideas? A cheap and easy fix would suit me just fine!!

Thanks,

Charlie
