Hello

I recently purchased an audi V8 3.6 1991
but its brake pedal is too hard
you have to push it very hard so the car can stop

Do you have any ideas what it may be

this is the most common problem on type44 models...
the bomb which acts as a reservoir for pressure in your system
goes bad...after all this stuff can't last forever...
actually considering yours is from 1991 that's not so bad

what will be bad is the price for those things...
there are some cheap alternatives out there maybe the other guys/gals can help
on that point.

I read something about the bomb and as i get it all my brake pedal should get softer when engine is running
Am I right?
The problem is that my audi's brake pedal is verry hard
no matter the engine is running or not. It does'n get even a little bit softer.

Can the Bomb still be the problem?
P.S.
What is the audi V8 1991 Brake Booster working with? (Oil or Air)
Where does it take supply from?


How can I check for shure where the problem is?

I have a problem.
Brakes difficult and the pedal vibrates by pressure.
Pump pressure in norm. But on a cold motor, the rudder is not pivoted.
When the engine will get warm, the rudder all over again can be turned to the left, and then after a while to the right.
I have replaced a bomb, but it not new. As it correctly to test.
