Hi guys,

I just got a 1998 mk1 1.7 turbodiesel and the brake pedal is hard when the car is started. I checked the vacuum pump and it seems ok and so does the camshaft. My next thought was:
1. Broken hose
2. Vacuum pump gasket
3. Brake servo

Also i noticed under the vacuum pump was wet with oil.

Any help is greatly appreciated.

Thanks alot

brake oil leak?

The reservoir of the brake fluid looks full

Highly unlikely that brake fluid would make it's way to the vacuum pump. Sounds like the vacuum pump has failed, possibly due to oil seal failure, but I don't know the exact set-up on your car.

What do you mean by setup? Maybe i can explain to you. Thanks

You say the pedal is hard when its started, does it get softer when the engine runs?

No it remains hard all the time even when the car is started

Sound like servo to me, how are the brakes?

The car breaks if i press hard on the pedal

Hi,
The servo id the large "can" between the pedal and the master cylinder. I uses vacuum /air pressure for power. If vacuum is missing or the servo is broken then the brakes still work but need a lot of effort. The only ways to tell if it is the pump or servo is to measure the vacuum or use an external vacuum pump to test the servo. The pump should "pull" a good vacuum, much more than a acuum cleaner. IT shold be hard to pull your finger off the end of a 10mm pipe with the engine running. Pump failure is more common than servo. The presence of oil could mean the seals have failed and its sucking engine oil from the camshaft area.

With the tip of your finger, touch the tip of your nose. Now, in a circular motion, rub your stomach and pat your head while saying 'Rubber baby buggy bumper

Know how to like and dislike a post but don't see a way of deleting if you hit the wrong one! (Easy to do from the phone) Anybody have a sensible suggestion? think i'll pass on Flisko's suggestion, seems to be a tad like typing Amen and sharing etc
