BRAKES
For safe riding it is crucial that your bicycle’s brakes function
correctly. With use the bicycle’s brake pads wear and the control
cables stretch. Consequently, prior to every ride the brakes
should be inspected and adjusted as necessary to ensure proper
operation.

WARNING: A bicycle should never be ridden unless the
brakes are working correctly. Take care when using the
front brake. Applying it abruptly or excessively may throw
the rider over the handlebars, potentially causing serious
injury or death.
Hand Controlled Brakes
There are five main types of hand controlled brakes used on
bicycles - the sidepull, the “V” brake, the “Linear Pull” brake,
“U” type calliper brakes, and disc brakes. All are operated by
the rider squeezing the control lever attached to the handlebar,
which activates the brake. Differences occur between the four
hand operated brakes by how they are mounted to the bicycle.
“V”, “Linear Pull”, and “U” type brakes use two brake pivot arms,
each mounted on separate pivots on either side of the frame or
fork. Sidepull calliper brakes are attached to the frame or fork by
a single pivot point. Disc brake callipers are attached to the frame
and fork via disc brake mounts.
Foot Controlled Brakes.
The coaster brake is a pedal activated brake fitted to most juvenile bikes and some BMX
bikes with out gear mechanisms. The brake is activated by pushing backwards on the pedal.
This activates a brake in the rear hub and allows the rider to slow or stop.
Inspection
The brake levers and the brake pads are the two main components that need to be checked
to ensure your brakes are functioning effectively. Positioning of the brake levers should be
checked to ensure they can be easily reached by the rider’s hands and alterations made
as necessary Some brake levers have a screw adjuster to change the distance between
the lever and the handlebar grip. This should be checked for tightness every three months.
Similarly, at least every three months the brake levers should be tested to ensure they do not
move on the handlebars and each brake lever moves freely when compressed.
Prior to every ride inspection of the brake pads is recommended. The brake pads must be
centred, with approximately 1.5mm - 2mm clearance between each pad and the rim when
the brakes are not in use. Test that when the brakes are applied that the brake pads squeeze
the rims sufficiently to stop the bike. Replace the brake pads if the grooves or pattern has worn
away from the surface. Ensure that the brake pads are firmly secured before every ride and
at least every three months check the tightness of the numerous bolts and nuts supporting
the brake pads. (D

If your bicycle is fitted with a Quick Release wheel mechanism, ensure that this is securely
closed after any brake adjustment. Never ride a bicycle unless the mechanism is firmly
locked in the closed position.
