14.12.4.6 Checking a brake pad
Brake pads must generally be removed in order to check them. The minimum brake pad
thickness may vary depending on the brake design.
x Minimum thickness specifications for the brake pads can be found in the
information enclosed by the manufacturer.
1. Remove the wheel (see the “Wheels and tyres / Fitting and removing the front/rear
wheel” chapter).
2. Remove the circlip from the screw and loosen it, or bend the ends of the pin
together and pull it out.
3. Pull the brake pads out of the brake calliper and remove them from the retaining
bracket.
4. Check the thickness of the brake pads with a measuring calliper.
x If the brake pad thickness does not meet the specified minimum thickness,
replace the brake pads as described in the previous chapter, “Changing brake
pads”.
14.12.4.7 Checking the brake system
x Check hydraulic brake systems for leaks, dirt and damage.
x Check mechanical brake systems for damage.
x Carry out a stationary functionality test.
14.12.5 Coaster brake
If it is necessary to back-pedal more than 1/6 of a full pedal revolution before the coaster
brake takes effect, then it must be readjusted by your dealer.
WARNING
No coaster brake action where the chain has dropped off the
chainring or the reaction arm is loose.
Risk of accident and injury!
x If the coaster brake has no effect, brake carefully using the
front brake lever.
x Check the chain tension regularly so that the chain cannot slip off the chainring
(see the “Maintenance / Chain tension” chapter).
