Using Brakes 

All bicycle models are equipped with a front and rear wheel braking system. Brakes are used to slow the 
bicycle down. The braking systems may use different mechanics, however, the functionality is the same, 
and that is to change the energy of the moving bicycle into heat energy ("friction"): 

 

For disc brakes, this means pads made from a special friction material pinching 
against a disc mounted to the centre of the bicycle wheel. 

 

For rim type "caliper" or "noodle" brakes 

or “V 

-

Brake”

, this means rubber blocks 

pinching the outer rim of the bicycle wheel (not the tyre). 

 

For drum brakes, this means pushing sections (known as "shoes") of special 
friction material against the inside of cylinder fixed to the centre of the bicycle 
wheel. 

 

 
 
The brakes are operated by the rider through levers mounted to the handlebars. The left-hand lever 
operates the rear brake, the right- hand lever operates the front brake. The ability of the rider to 
adequately slow and/or stop the bicycle depends largely on the skill of the rider, the surface being ridden 
on and other factors such as rain, tyres, adjustment and condition of the brake parts etc 
 

Guidelines for Using Brakes 

To get the best performance and service life from the brake system, understand and apply the following 
techniques: 

 

In wet conditions, which reduces friction, always provide additional distance for braking and 
adjust how quickly you apply the brakes. 

 

When applying the brakes, particularly the front brake, use a lower pressure to start with until 
you feel the brakes starting to "bite", then increase pressure as required. Do NOT over-apply the 
brakes and cause the wheel to stop rotating 

 this may result in loss of control. 

 

Maintain the brake friction components (pads, shoes, rubbers) in good condition and replace 
when they reach the wear limit. 

 

Maintain brake adjustment so that the brakes perform effectively, the levers are comfortably 
positioned, and there is not excessive play in adjustable components. 

 

If the brakes are not performing effectively, making abnormal noise or any part is not serviceable 
or cannot be adjusted correctly, have the brakes inspected and adjusted by a bicycle mechanic or 
suitably qualified person. 

 

If the brake cables become frayed or otherwise damaged, have them replaced by a bicycle 
mechanic or suitable qualified person.
