Dude, fitting those sensors r considered as luxury n unnecessary items for a budget compact like a Kancil.
Most likely ur handbrake release switch or its connection is faulty/loose. Think most mech or accesory shop guys can help u on tis.
You don't need sensors on the brake for that. Whenever brake pads wear out, the brake fluid in the reservoir will drop to fill the gap left by the worn out. The fluid level usually drops to min level and this will illuminate the so called 'brake warning' indicator. That indicator has 2 functions, one to tell you when the handbrake is up and the other when the brake fluid is low. This is how people usually associate this warning light with brake wear as it would trigger the low brake fluid warning.
The usual steps would be to check brake fluid level before anything else. If it is low, then check brake pads to see if the low level is caused by worn out pads. If not, then check for leakage. Only if there is nothing wrong with the brake pads/fluid level do you then check for handbrake sensor which seldom fails.
