Servicing the brakes
The hydrostatic drive is used as an operating brake and operates equally without wear resistance on all four wheels.
In addition, the loader has a foot brake and parking brake.
The foot brake and parking brake consists of a hub brake on the differential. The parking brake is actuated via a bowden cable, by means of the handbrake lever. The foot brake is activated hydraulically via brake lines and main brake cylinders by means of the braking-inching pedal.
WARNING
Personal injury hazard.
The service and parking brakes are essential for safe operation of the wheel loader. Loss of control is hazardous to the operator as well as other people on the work site or public roads.
►
Always check brake performance at the start of each work shift and stay alert to changes in response or capacity. A loss in response or capacity must be corrected.
►
Stop the wheel loader in a safe place and lower the loader lift arms and attachment to the ground.
►
Stop the engine and notify the supervisor or a technician to diagnose the brake system and make any needed repairs before resuming work.

Servicing and inspection
Checking the brake fluid level / adding brake fluid
WARNING
Health hazard.
Brake fluid can be absorbed into the skin or cause infections.
►
Avoid contact with skin and eyes.
►
Wear protective gloves and eye protection.
Using the wrong brake fluid damages the brake system.
Only use brake fluid approved by Wacker Neuson for the braking system (see Section 10.6, page 165
»Specifications and fill quantities«).
If you are frequently adding brake fluid between inspections, then there is a system leak. Do not work with the loader again until the faults have been eliminated.
ENVIRONMENTAL NOTE
Avoid environmental damage.
Do not allow oil and waste containing oil to spill on the ground or get into bodies of water.
Collect leaking transmission oil and dispose of it in an ecologically sound manner.

The brake fluid reservoir is on the left at the back, under
neath the engine enclosure (Fig. 91). The control marks
»MAX« and »MIN« are on the side of the container.
If the brake oil level in the brake fluid container falls below the »MIN« mark, fill with prescribed brake fluid up to the
»MAX« mark and have the brake system checked by a trained specialist.
