[urq] bomb test variation with S4 brakes?

[Martin Pajak]

Brady,

Number of of times you can pump the brakes will only be determined by your
pedal travel, not what brakes you have..
If you have air in the system or spongy hoses, your pedal travel will be
longer and number of pumps less.. however I can not see how that number
can be reduced to 10 if you have properly functioning brakes.

Hmmm... try this.  Empty your bomb, mark the level in the reservoir.  Then
run the car for few minutes to charge the bomb and measure your fluid
level once again.  Let me know how much is gone and I can can compare with
mine.

This will let you know if the bomb is charging to it's capacity.  If not
the pressure on the bomb might be higher than stock.

Hope this helps.
