20.1.1 Checking the pad thickness of the brake shoes
The pad thickness of the brake shoes must be at least 2 mm thick.
If the pad thickness is less than 2 mm, the brake pads must be replaced by a KRONE service
partner.
20.1.2 Checking the stroke of the brake cylinders
„
Actuate the service brake at full pressure.
„
Check the stroke of the brake cylinders.
Æ If the stoke on the clevis is more than two thirds of the maximum cylinder stroke, the brake
must be adjusted.
Max. cylinder stroke for 9“/12“ diaphragm brake cylinders: approx. 60 mm
Max. cylinder stroke for 16“/20“ diaphragm brake cylinders: approx. 75 mm
20.1.3 Setting brake lever on the single axle
Due to the naturally occurring wear of brake drums and brake pads, the brakes must be
regularly checked and adjusted.
To ensure correct functioning and adequate brake power, the distance between the brake pad
and brake drum must be kept as low as possible. This distance is set on the brake lever.
Brake actuation has been set in the factory. An adjustment is required if
• the braking effect decreases (e.g. due to the brake pads wearing) and/or
• the actuating stroke of the brake cylinder is greater than two thirds of the maximum cylinder
stroke.
Max. cylinder stroke for 9“/12“ diaphragm brake cylinders: approx. 60 mm
Max. cylinder stroke for 16“/20“ diaphragm brake cylinders: approx. 75 mm
