When I press down on the brakes once I have taken my foot off the pedal it makes a hissing sound until you press the brake again to stop it. Any ideas as it has an mot next week and want to sort it out prior to then. Thanks in advance

I have just determined that the HISSING is related to when I use the brake pedal!There is a small hiss when applying the brake but sometimes get a constant hiss when the brake is released.Anyone have any ideas please?


hi at the back of brake pedal is a grey rubber gater which is covering a hose which after time hose can split a cheap fix,if you push the gater when engine running you can hear the hiss,my garage told me it was the servo as well but my pedal did not get hard to press.hope this helps
