Hi guys, wanna ask anyone Vios 2020 got the below issue:
1) when car low speed driving will have "rusty whining/bearing/wukwuk" noise coming from Engine Bay i supposed, high speed no such noise at all
2) The noise will be extremely loud when going downhill and turning left / right
3) Only occurs when 10-30kmh, higher than 40kmh definitely no sound
- Tried stepping on brake on low speed slowly, the sound remain, pretty sure its not disc rotor issue nor pad
- If its pad / rotor, high speed braking will be even worse, however, high speed driving or braking no noise at all
4) I went to SC, they only relining disc rotor
5) When to outside tyre shop, lift car up, let car on D, 10-30kmh, will have
- 4 Brake pipe (Steel/copper) undercarriage will have "tak-tak" knocking sound, then when hold on it will feel the knock
- The brake pipe (Rubber) connecting to brake from steel pipe also will have the knocking feel if we hold it
