consequence that the adjustment device 20 for the brake cable 7 can be arranged directly at the cable outlet 19 the sensitive cable adjustment device 20 is thereby arranged outside the point of access for roaming animals such as martens or the like and in the case of repairs is easily accessible via for example a swing up flat side of the housing 5 in its released or deposed initial position the foot operated parking brake 1 is in the position illustrated in fig1 the engagement nose 24 of the locking pawl 22 is deposited in the rest space 25 and the adjustment device 20 by virtue of the force of its spring adjusts the brake cable 7 when the brake actuation lever 3 then is pivoted about its articulation 4 by the pedal 2 being depressed a locking mechanism of the adjustment device 20 causes the brake cable 7 to be locked in the set position and via the extension 17 the joint 16 is pivoted about the articulation 4 at its distance from the latter the intermediate lever 15 transmitting this pivoting movement in turn via its articulation 14 to the deflection lever 13 with the result that the latter likewise executes a pivoting movement about its joint 12 in relation to the lever holder 5 at the same.
