For certain rear shock absorbers, the lower seat for the coil spring and the rear axle beam are not properly welded, and the welding may give way because of vibration during driving etc., which could cause the seat to tilt and subsequently the brake pipe and the rear axle beam to interfere with each other. If the vehicle continues to be driven in such a state, the brake pipe may be damaged, and in the worst case, brake fluid could leak, resulting in reduced braking efficiency.
