A brake actuating assembly for use in a vehicle includes a clutch assembly that includes a pinion provided on one of a lever and a mounting bracket of the actuating assembly. The pinion includes a shaft and a plurality of teeth that interact with an arcuate rack of teeth provided on the other of the lever and the mounting bracket. The clutch assembly also includes a torsion clutch spring that includes a plurality of coils wrapped around the shaft of the pinion, a fixed end at one end of the coils, and a free end at an opposite end of the coils. At least one of the shaft of the pinion and the spring is tapered in an axial direction thereof such that an interference fit between the spring and the shaft is lower near the free end of the spring than near the fixed end of the spring.
