Causes Analysis
If the brake pad producing a "jit jit" metal grinding noise when you press the brake pedal, it might be due to the brake pad has reached its life span or has severe worn. Suggest to replace the brake pad at the workshop. You may also determine if the brake pad has been fully utilised with the below ways:
1. There is a metal protruding point with about 2-3mm thickness on the brake pad which its function is to produce eye-piercing noise to warn the driver when brake pad is fully utilised.
2. Usually the thickness of the brake pad is around
1.5cm, if the brake pad has only 1/3 balance, need to take extra precaution to it.
3. If the brake is used frequently during daily drive, it will need an inspection when reaching 20k - 30k kilometer mileage to determine if an replacement is needed. If the brake is used less frequently, then the inspecton can be conducted at 50k kilometer mileage.
4. If the braking power is weak and need longer time to stop the car, an inspection should be done to the brake to determine if an replacement is needed.

Solutions
Suggest to diagnose at workshop, the usual keypoints of diagnose are:
1. Check if the brake pad has reached its life span, replace if it is. Please take note when replacing new brake pad, need to differentiate the inner and outer side of the brake pad, and push the piston back to its position before tightening the brake caliper, hence it is not encourage for owner to do it on their own to prevent unwanted incident.
2. Reinstall the wheel after installation done, at the same time inspect the wear level on the tyre surface and edge. Check also if need to refill or replace the brake fluid.
