Did it. I assume pushing in something like an inch before hitting
hard means my bomb is dead. :( With the engine on I pushed the
pedal as far as I could. At the bottom of the travel, right through
my CATS I could feel the hideous shudder. Drat. And Darn, too.
So it seems my baby has blown its bomb. Would this be the cause of the
low pressure warning signal I am getting? There are no sensors
connected to this thing, right?
Okay, so if this has to be a replacement job, just where exactly or
what exactly is this thing? Is this the brake pressure regulator that
is connected to the rear axle via a spring? Haynes indicate a
procedure for resetting it, but it requires measuring equipment.
Am I thinking of the proper thing?
Thanks for the help. :)
Cheers!
