It is probably the Brake Master Cylinder.  Check your fluid level and if it
is full then it is definitely the Brake MC.  If it is low then you could
have an external leak.  If you need anything please let me know as we have
all of these parts in stock.

Hello,

What does it mean when you are stopped, lets say a light and your brake
pedal starts to slowly lose resistance and starts to move toward the floor
of the van.  When I take my foot of the break and reapply it the resistance
is back and then it starts again.

Thanks in advance for any advice.
