Check to make sure brake is adjusted properly.
1.Drive the machine onto a level surface.
2.Disengage the blade control switch (PTO), move the motion control levers to the neutral locked position and set the parking brake.
3.Stop the engine, wait for all moving parts to stop, and remove the key.
4.Raise the back of the machine up and support the machine with jack stands.
5.Remove the rear tires from the machine.
6.Remove any debris from the brake area.
7.Rotate the drive wheel release handle to the “released” position. Refer to the Drive Wheel Release Valves section in Operation.
8.Disengage the park brake.
9.Using hands and fingers only, push the caliper lever arm to engage the brake pads on the rotor until the lever stops. While holding the lever at the stopped position, use the other hand or fingers to pull the cable threaded end tight through the swivel. Spin the standard nut against the swivel (see Figure 30).

5.Standard nut (shown against swivel)
Note the order of the standard nut and lock nut (no nut on the cable anchor side of the swivel).
10.Release hold on the caliper lever and cable. The wheel hub should turn by hand in both directions relative to the caliper; some friction/resistance is acceptable.
11.If there is no movement between the hub rotor and the caliper then back off the standard nut one turn from the swivel and repeat step 10 (drive release valves must be in the “released” position on the hydros).
12.If the hub rotor moves very freely relative to the caliper, then tighten the standard nut one turn against the swivel and repeat step 10.
13.Once step 10 is achieved, hold the threaded rod end with a tool and tighten the lock nut against the standard nut. Do Not allow the cable to turn when the nuts are tightened.
14.Rotate the drive wheel release handle to the “operating” position. Refer to the Drive Wheel Release Valves section in Operation.
15.Repeat on the opposite side of machine.
