Re: [DML] Brake booster/Servo troubleshooting



Ed,

do you feel a difference at the break pedal when the engine is
off or when it is on ?
When on, the pedale should be much easier to be pushed.

BTW - what is a "vacuum noise" ?

How many miles have you put on the new (?) pads ?

When bleeding new capilers you have to make sure that the 
outer side has no more air trapped in it ! Just regular 
bleeding won't get it out !


The vacuum line ends on the right side in the engine bay
where it goes to a T-piece and splits up for the vacuum reservoir
and where it connects to the right side of the intake manifold.
