How to adjust the brake shoes alignment
V-brakes type: Disconnect the joint tube and with a hand, squeeze firmly the brake shoes
against the rim and from the other hand, pull the tub backwards from the joint and raise it
up. Once disconnected, the tube is to come free. To closet he brakes, follow these same
instructions in reverse order.
Lubrication
The brake lever pivots should be lubricated every 3 months with a synthetic lubricant, the
same as it is used for the chains.
When installing a new brake cable, it should be lubricated with a thin coat of synthetic
lubricant.
9.6.2 MECHANICAL DISC BRAKES
Instead of using a brake shoes to press on the wheel rim, a pad squeezes in a disc placed
on the front wheel or rear wheel hub. The disc is fitted to the axle by means of bolts on the
left side. The brake is activated by means of a cable connected to the brake lever.
The braking system consist of the following:
- Brake lever
- Brake cable & casing
- Brake disc pads
CAUTION. The disc brakes may be very hot after using them. Be careful
when inspecting them. As with other bicycle parts, avoid placing fingers
inside the disc.
Squeeze the brake levers 10 times before riding. The levers should not touch the
handlebar.
Ensure that there is no oil, grease or any other matter on the disc. The disc is part pf the
braking system and should always be kept clean. Remove the pads from their supports for
a deep cleaning. Do not use any cleaning products, degreasing liquids or solvents to clean
the disc. Only use isopropyl alcohol.
Ensure, once a month, the disc brakes not to be worn out. If the brake pads are less than
1 mm thick, they will have to be changed. Also, check the pads to be correctly positioned:
A distance between 0.25 and 0.75 from the disc when not using the brakes. Turn the
