• 
Check the brake pads for wear, see (BRAKE PADS). 
• 
If the pads and/or the disc do not need replacing, 
provide for topping up. 
 
TOPPING UP THE FRONT BRAKING SYSTEM 
 
 
WARNING 
Danger: brake fluid could leak out. Do not 
operate the front brake lever when the brake 
fluid reservoir plug has been loosened or 
removed. Use a cloth under the brake fluid 
reservoir to prevent any fluid leaking off. 
 
Unscrew and remove the plug (1). 
 
 
 
WARNING 
Avoid long exposure of brake fluid to air. Brake 
fluid is hygroscopic and will absorb moisture 
from the air. Keep the brake fluid reservoir open 
JUST LONG ENOUGH to top up level.
 
 
• 
Remove the gasket (2). 
CAUTION  In order not to spill the brake fluid while topping 
up, do not shake the vehicle. 
• 
Top up the reservoir (3) by adding brake fluid, see 
(LUBRICANT CHART), until bringing level between the 
MIN" and "MAX" marks. 
 
 
 
WARNING 
Never exceed the “MAX” level. 
It is advisable to top up until reaching the 
"MAX" level only with new pads.  
When the disc pads wear out, the level of the 
fluid decreases progressively to compensate 
for their wear. 
Do not reach the "MAX" level with worn out 
pads, since this will cause a fluid outflow when 
the pads are changed. 
 
• 
To refit components, follow the disassembly procedure 
in reverse order.
