1.8Tdci brake pedal hissing

[Hellboy1980]

Hey all,

Today while out and about my brake pedal went hard. I was able to stop still. I carried on as it was on a roundabout and when I was off the roundabout the brake pedal seemed to go down again. However the brakes just don't feel right.

Checking all the vacuum pipes I could see nothing but came across this at the top of the brake pedal where it meets the firewall. Could this be causing the hissing and brakes not working as they should be?

It looks like a split grommet to me

Cheers

I would say the chances are you servo is leaking and that is the hissing you hear and the reason for a hard pedal
