My brake creep problem has still not been resolved, dealers deny any problem!
It would be most helpful if everyone who has an Omega tests for this problem and tells me whether they have or do not have the same symptoms. Rather than clog up this web site with those messages, please just send me an email saying "I have same brake creep symptoms" or "I do NOT have same brake creep symptom. " The ones that do NOT will confirm that this is NOT normal, the ones that do will indicate the scale of the problem
Thanks

This continuing problem is only one of many reasons to believe that the world has gone mad!
Symtoms of brake problem on Y reg Vauxhall Omega Estate 2.2 litre petrol engined.
1/ Pedal travel is long, and feel then "spongy"
2/ Applying normal pedal pressure to stop, eg for a red light, and then maintaing that pressure (not increasing it) results in the pedal creeping slowly down until eventually it (seems to) hit the end of travel of the master cylinder.
3/ Releasing the pedal and then re-applying it rapidly results in much less pedal travel and a firmer "feel" - followed by the same slow creep down.
As the master cylinder has been changed to no effect, and there is no loss of fluid from the resevoir, these symptoms tell me - with the aid of comments from many of you and various web sites - that there is a slight leak in one or more of the ABS valves, due to corrosion or debris keep it or them slightly open.
This "creep" was not noticeable a month ago when I got a new MOT, and when I first noticed it a week or so later - because I had been bleeding brakes on another car - it took higher than normal pressure to notice very slow creep - to the point that I had to check several times to make sure it was happening.
Now however, after no more than another 50 miles, it happens with perfectly normal pedal pressure, and the rate of creep has increased to the extent that the pedal reaches the limit of its travel in the time it takes traffic lights to change from just going red to green.
All of these tell me that this is a dangerous fault that is getting rapidly worse and that I should not drive it again until it is fixed.
However the Vauxhall main dealer gave it back to me again just before Christmas flatly denying that there is any problem - that these symptoms are "normal" - they have not commented on the fact that the symptoms are getting rapidly worse. Another Omega in for service had the same symptoms, though not as bad as mine.
I telephone VOSA (Vehicle Operators Service Agency) who checked and told me that this is not a safety critical fault (!) and that modern engine management systems do cause the pedal to go slowly to the floor when the car is stationary - but that the ABS system knows when the wheels are turning and immediately restores proper operation!
They were unable to explain why anyone would design a system to do this, nor why the symptoms would change and get worse. Nor why any designer felt it necessary to reduce braking power when stationary - they had no answer to my question of what happens when stopped at road works, for example, on a steep hill.
I did not think to ask them wny no explanation of these symptoms - which would clearly worrry anyone not familiar with them - is given in the drivers' handbook.
It is of course not possible to check for these symptoms when on the move, because pedal pressure necessary to show up the symptoms would bring the car to a halt before the creep had become noticeable.
Yet despite these "explanations" a MOT testers web wite states unequivocally that brake creep of this kind is an automatic "fail"
Comments please!
