Hi All
I pumped my break pedal a few times yesterday and the revs built up to 2K.
Surely this isn't correct, what would the reason be please?
Cheers
Dave

Sounds like a leaking brake servo to me. :-\
-
Thanks Kevin
Could this also be the answer to excessive fuel consumption that doesn't show on the MID?
Mine says 18.0 to .06 but the gauge and stops for fuel indicate 6/7 mpg.
MOT's up at the end of this month...yikes!

That fault wil be a MOT failure, A few years ago (sorry many years ago) i had a marina that failed because of that, get a replacment from one of the srappers on here. :y
-
Shouldn't leave it too long - had the servo seals go on my TR4A and there was a great cloud of whiteish smoke out the back as all the brake fluid went through the engine and was burnt off - result no brakes although handbrake was good up to 40mph!
-
yeah I know Gary. Just another problem to sort out. It's gonna fail anyway...the EML's on. I'm dreading the MOT lol thanks for the input
Cheers for the warning dbug
Is there a repair kit available?
-
Don't know about the Omega, but got some for the TR - not TR parts as the servo was off a BMC land crab.

Robseyv6 is in west sussex and will have a replacment servo for your car and reasonable price too.

Thats probably the best route mate ;)

Cheers fellas. I'll contact Robseyv6 after I had a look tomorrow.
Ere whilst I'm here. Does the MAF have an earth for itself? I've done another post relating to this in http://www.omegaowners.com/forum/index.php?topic=112311.0 (http://www.omegaowners.com/forum/index.php?topic=112311.0)
My car really can't decide whats wrong, seem to have 101 different symptoms, she's doing my head in lol

Thats the first brake servo failure on an Omega I have ever heard of so second hand is a good source, beware that there are at least two types (the facelift is certainly different as it has a power stop servo)
As for the brake fluid ingestion, that would require the master cylinder to fail in a big way plus the master cylinder to servo seal so very unlikely on this setup

What's one of them? :-\

If you also have MAF related issues bear in mind that the servo could be leaking air at all times and this constitutes an unmetered air leak. Fix the servo first and you may find all is well.
As for diagnosis, stop the engine and see if you get a few pumps of the pedal before the assistance is gone. Check the servo feed pipe for leaks as well. This can often chafe on things if it's not been routed carefully. Does sound like the servo itself to me, though.

It has an additional valve which opens when you hit the brake pedal hard/fast giving greater assitance and improved stopping distances

Ta. Can't say as I've ever heard of one before. :y

Cheers guys :y
All seems ok now and I didn't do a thing, well apart from disconnect a couple of pipes and put reconnect them.
There's a bit of assistance after switching the engine off and no high revs when pumping the pedal.
But the servo does seem to move a bit when the brake pedal is pressed down.
Not only that the EML has gone out!!!
The light came on with a Chinese MAF in and I couldn't be bothered with it so left it plugged in.
Dunno why, perhaps this crossing fingers does actually work after all ;D
Shame I didn't do anything to put on here to help others.
Thanks
Dave
