BRAKE
The brake is different to the Gas and Clutch
as it uses the elastomer dampeners found in the
accessory box The procedure is still straightforward
though Once the piston has been lifted clear from
the pedal module you need to open the piston
in order to access the elastomer pieces inside it
To do this grip the knurled cap at the top of
the piston in one hand and then unscrew the body
of the piston from the cap
Once the piston body is removed from the cap,
turn it upside down and shake the elastomer pieces
out They will be slightly sticky with lubricating
grease so do have something available to wipe
your hands on
You will notice that there are three pieces of
elastomer or foam in the piston body: two of equal
size and one slightly smaller one The smaller piece
must always be present in the piston body with
the other two pieces determining the overall feeling
of the brake pedal, enabling you to configure
to be fairly soft with a larger range of travel or,
alternatively, as hard and limited in travel as some
real race cars Also, the small piece should always
be at the bottom of the piston:
