MAINTENANCE OF DRIVING BRAKES

CONSTRUCTION OF BRAKES

- Kesla XS 190 has driving brakes both in front and rear axles, located in the wheel
hubs.
- Disk brakes are opened by hydraulic pressure.
- When the pressure of the drive motor exceeds 30 bar, the disk brakes open, and a
spring automatically closes the brakes when the pressure drops below 30 bar.
- The design of the brake caliper is "floating", which means that a spring presses one
of the brake pads, but the slide mechanism compensates the compression pressure of the
spring, and both brake pads of the brake caliper press against the brake disk with an equal
force, on both sides of the disc.

MAINTENANCE OF THE BRAKES:

- Check that the brakes press on the both sides of the brake disk with equal forces –
clean, lubricate and check the functioning of the floating brake caliper mechanism every 6
months, and in difficult and dirty conditions even at shorter intervals.
- If the brake pad located on the spring side is clearly more worn, the mechanism
must be cleaned and lubricated.
- For instance when towing, the drive brake can be released by replacing the
hydraulic hose nipple at the brake cylinder with a special nipple found in the toolbox, and
screwing an M8 bolt in the threaded hole of the nipple.
- Replace the brake pad if the thickness of the friction surface is less than 1.5mm
(0.06in).
