Brakes
UNI MK Classic/Swing comes standard with hydraulic disc brakes both front and rear. Disc brakes consist of the brake calliper, the rotor/disk, the
hydraulic tubing and the brake lever. Actuating the brake lever compresses the hydraulic pistons through hydraulic pressure pushing the brake pads
against the rotor. The friction generated by braking causes wear to the brake pads as well as the rotors.
Riding with improperly adjusted or worn brakes is dangerous and can result in injury or death. Check the brake manufacturer's
instructions for care and operation of your brakes. Keep brake surfaces clean and free from oil or lubricants. Replace worn
vbrakes with authorized replacements.
Replacements of brake caliper pads should be done by a qualified e-bike mechanic.
Brake check
1. Pull on the brakes levers. At the end of their travel, they should not be in contact with the handlebars.
2. Lift and spin the wheels. They should spin freely. If this is not the case, you will need to adjust the brake caliper. This is a complex operation
that needs a lot of care: loosen the clamping bolts, fully tighten the brake lever and tighten the clamping bolts. If after this adjustment the wheel do
not spin freely contact your local retailer so that they can carry out the operation.
3. Once the adjustments have been carried out, it is essential that you test your brakes at a standstill to make sure that they work properly.
4. For brake pad replacement contact a professional mechanic.
Disc brake systems require a run-in period before they reach optimal performance. It is possible that the braking power
is very weak during first rides. It is recommended to ride with great caution during this run-in period. Do not keep the brakes on
for long periods, as this will result in brake pads glazing over, reducing their power and efficiency. As a general rule, the pads
are run in after approximately 50 repetitions of braking from high speed. Usually the brakes are completely run in when the
braking power stops increasing with each run.
Disc brakes can reach a very high operating temperature. Do not touch them, especially after a long descent, as you
can burn yourself.
Dirty brake pads and rotors can lead to drastically reduced braking power. Make sure the brake remains free of oil and
other fluids. Dirty brake pads can under no circumstances be cleaned, they must be replaced, while rotors can be cleaned with a
special brake cleaner or with warm water and mild soap.
