The clutch and service brakes are operated by suspended pedals, which are mounted on a common shaft.

By mounting plates on the pedals, the distance to the pedals can be reduced by 15 to 30 mm.

The clutch pedal (1) rides on the shaft with two needle bearings to keep the operating force as low as possible. An over-center spring reduces pedal effort from approx. 21 kp to 14 kp.

In the released position, the spring's force will be slightly in the direction of the pedal stop (2).

If the clutch pedal is depressed, spring (4) will assist the foot force depending on the pedal travel {max. approx. 140 mm).

With the wing nut (3) the assistance can be adjusted by approx. 8 % to 33 %.

The operating force, consisting of foot force P and spring force F, is transmitted to the clutch master cylinder (7) via the push rod (6). For perfect functioning of the clutch operation there must be 0.5 mm clearance between the push rod (6) and master cylinder piston (8). Adjustments can be made with the threads of the push rod (6). There is an automatic adjustment after each operation of the clutch by way of the springs (9) in the master and slave cylinders to make up for wear on clutch parts. The clutch is maintenance free.

The master and slave cylinders as well as the connecting lines are filled with brake fluid. The supply is via a separate line from the brake fluid reservoir.

The reservoir has partitions, so that a leak in the clutch system will not impair the functioning of the brakes.
