To address the issue of front brake low-frequency squeal of passenger car, a mathematical model and multi-condition matrix of stability analysis of braking system were established, and stability of the braking system was analyzed with complex mode simulation. The results show that the unstable mode appears in the system under 1 830 Hz, which is in good agreement with the vehicle brake squeal test results. Components and their modal contribution analysis method were used to analyze the unstable mode. The results show that the first torsional mode of the caliper and the first bending mode of the pad are the biggest contributors to the unstable mode. The brake caliper and pad were optimized. The results show that the 1 830 Hz unstable mode becomes stable after the caliper structure is strengthened, the system stability is improved after the pad material and structure adjustment, whereas it is still in the unstable interval, and the squeal is difficult to remove, which is consistent with the experimental results, and the subjective evaluation result is acceptable.
