“…For instance, some researchers (Liu et al, 2007;Trich锚s Junior et al, 2008) considered only the disc brake and two pads. Hassan et al (2009) added the finger and piston to the FE model. Dai and Teik (2008) developed a FE model consists of rotor, caliper, mounting bracket, piston and brake pads to analyze the design of disc brake pad structure for squeal noise reduction.…”
