Brother always remember one thing, never compromise in breaks, always use GENUINE Break Pads, never use low quality or copy, these roadside mechanics may lurr you that "oo g yeh genuine waghaira kuch nai hota, yahee cheez company mai genuine keh k bechtay hain".
You may go to any Toyota showroom's Parts section, tell him your car's model, he will provide you the pads, and get them installed from your own mechanic.
