Maintenance Procedures: (continued) 
 

3) Brakes: 

 

   Brakes are one of the most important safety parts of the bike. 

Read this section carefully and understand it. If you are unsure of any 
details, seek professional advice. It is recommended that a                             
professional mechanic adjusts, services and cleans the brakes.  

 
About the brakes: 
 

The LPR12 Jnr MX™ is rear brake only. It is a cable operated disc brake located on 
the rear wheel which is operated by the brake lever on the left side of the handlebar. 
The brake lever is “short throw” and close to the bar for kid’s small hands. The disc is 
bolted onto the rear wheel and the pads inside the brake caliper assembly clamps the 
disc when the lever is pulled to activate the brake. The brakes should be tested prior to 
each ride for correct function. 

 

 

 

How to Test the brakes: 

Test brakes by pulling the brake lever whilst pushing the bike forward. The 
rear wheel should lock easily with a light pull of the lever. The lever should 
spring return nicely and the brake should be fully activated before lever 
reaches 10mm from the bar. 

 
If brakes are unsatisfactory, you may need to adjust the cable tension or free play, replace any 
worn parts as needed, or clean and service if braking power is poor.
