GRACE MX II Operating instructions
Pressure point: Each brake has a certain amount of idle motion at the brake lever.
When this idle motion is overcome with a small amount of handforce the brake will
apply, the pressure point is reached. If the brake is properly adjusted and vented,
applying a greater handforce
will result in a higher braking performance while
moving the brake lever a shorter distance.
Brake pads and discs wear due to friction. The more often you ride in a hilly
environment or through rain or dirt, the higher the wear.
The braking system on the GRACE MX II has a fully-automatic pad synchronisation
system. This system balances the wear on the brake pads so that the pressure point
of the brake is always constant.
The wear condition of the brake pads can be checked with the transport securing
mechanism. The pads are worn and must be replaced when the thick end of the
transport securing mechanism no longer fits between the lugs on the brake pads
while the brake is applied.
New brake pads must be run in until they reach their optimal braking performance.
Accelerate the bike approx. 30
-
50 times to around 20 km/h (19 mph) and brake
until the bike comes to a stop. If the necessary handforce stops falling to brake, the
run
-in procedure is closed.
3.5. Checking the spring fork (RockShox Domain, RockShox Sektor)
Before each ride, clean dirt and contaminants on the upper tubes and check them for
scratches.
Lubricate the seals and tubes before each ride.
3.6. Checking the screw connections
Before each ride, check whether the following screw connections are tightened firmly:
• Securing the front wheel
• Securing the rear wheel
• Securing the grips and brake levers. It must not be possible to twist them.
• Securing saddle and saddle post
