Constructive arrangement introduced in brake beam applied in afinau00c7u00c3o of musical instruments, more precisely, it is the brake (1) of the type used in musical instruments (IM) equipped with a rod, or pedal height adjustment devices; said brake (1) is installed on the rod of Athena Tion (VF), especially.Between the knob lock upper (MT1) and the knob lock lower (MT2) both set out in document mu 8900039 - 0; said brake (1) consists of a set of axial parts (CP) fitted with means of fastening (MA) that define the sliding of the rod of Relaying (VF).And set pieces (CP) is defined by a central pipe (2) provided with external thread (ZA) with an internal diameter (x) developed for the receipt of the rod (VF); the extreme portions (2b) / (2C) receive latches (T1) / (T2).Which are presented in the form of containers (3) with a central hole (3a) is defined for the receipt of the rod (VF); each container (3) receives respective bushes (4) made of Teflon with troncu00f4nico format.Since the bushing (4a) of the extreme upper lock (T1) provides tear pressure regulator (4b) which when pressed against the rod (VT) by means of tapping the lock (T1) promotes the closing (FT) or opening (AB) in order to retain or release the sliding of the rod (VT). Consequently, Lib Erau00e7u00e3o or retention of the movements of the pedal (PD) laid down in the musical instrument (LM).
