Hi All
![](./images/smilies/spacer.gif)
I have just rebuild all 4 calipers with new seals so know they are not leaking and having problems with tiny air bubbles when bleeding.

I've bled many brakes before and have never had problems like this.

There is a constant stream of tiny air bubbles in the bleed tube.

I am using the old fashioned way of bleeding with tube attached to bleed screw and the other end in a jar.

I have the engine running when bleeding so the servo is assisting with pumping the brakes.

I've also noticed that the engine revs up

(car in neutral) when I pump the brake pedal.

This leads me to think that the engine reving up when I press the pedal and the constant tiny air bubbles are related

- maybe the servo is faulty and causing both symptoms.

Anyone got any thoughts? thanks
