HOW TO REMOVE THE WHEEL
To remove the wheel in case of disc brakes it is not necessary to dismantle the
brake system.
Carefully slide the disc off the brake when removing it from the brake.
When installing the wheel, carefully guide the disc between the brake pads.
If you press the disc rim hard against the pads, the pads may fracture or be
damaged and need to be replaced..
LUBRICATION
Every three months lubricate the pivots with synthetic lubricant, the same as
for the chain. Brake pads do not require lubrication.
MECHANICAL DISC BRAKES
Instead of pressing the shoe onto the wheel rim, a pad acts on a disc which is
positioned on the front or rear reel. The disc is attached to the axle by bolts on
the left side. The brake is operated by means of a cable from the brake lever. The
brake system consists of:
Brake lever / Brake cable and casings / Disc brake pads.
Disc brakes can be very hot after use, so be careful when inspecting them.
Avoid putting your ngers on the disc.
DANGER! Disc brakes can become so hot that they burn the skin. Also, the
edges may be sharp and can cut. Avoid touching the disc or brakes when they
are hot or when they are rolling..
INSPECTION
Before each use, tighten the brake levers rmly 10 times. It must not be possible
to touch the handlebars with the levers.
Make sure that there is no oil, grease or other dirt on the disc. The disc is
part of the braking system, so keep it clean at all times. Remove the brake
pads from the calipers when deep cleaning. Do not use cleaners, degreasers
or solvents to clean the disc. Use isopropyl alcohol.
Once a month check the disc brakes for wear. If the brake pads are less than 1
mm thick, they should be replaced. Also check that the pads are in the correct
position, 0.25 to 0.75 mm away from the disc when the brakes are not applied.
Turn the wheel, when the levers are not pressed down, the pads should touch
