Noise during braking |
Grinding, digging and crackling noise |
Ginding noise can be heared on partial pressing onto brake pedal. No repair is necessary when you apply strong power onto brake pedal and you do not hear any noise. |
Reasons for digging noise |
Noise is due to space between calipier and shoe when you move with low speed and bad rough roads. Brake pad and shoe is replaced. |
