The extent of brake pedal is how it is positioned from the surface of the car floor and if it deviates from prescribed standards, it has to be corrected. To fine tune, relax the locknut and move the pushrod out to clearance and turn the pushrod to set the pedal height at midrange before tightening the locknut again. At the brake pedal, loosen the locknut on the brake switch and retract the switch; for measuring height carpet should be pulled back and it is essential that the pedal is fully returned. Loosen the car brake pedal switch and turn it clockwise to engage the pedal arm just, unlock the switch and turn it anti-clockwise to create room and fasten the switch locknut. Freeplay is the distance that the pedal can be pressed down until it impacts on the brake system and if it falls outside this, what is required is the adjustment of the freeplay. If necessary, unscrew the brake pedal switch to obtain more free play and then turn it to the right tension before lock-nut tightening. Before any changes blocking the engine, should press the brake pedal a few times, define value of freeplay, if necessary it is necessary to turn back locknut on the pushrod, regulate freeplay in the specified range and again to tighten locknut.
