Squealing brakes

Question : THERE is a squealing sound when I apply the brakes of my Proton Saga, more pronounced in the morning but still present throughout the day.

My car is two years old, with mileage of 12,000km.

When I serviced my car,  complained about the sound but was reassured that it was due to dust, and that cleaning the brake discs by blowing away the dust would eliminate the sound.

However, the sound still persists.

Answer : Brake squeal is usually due to the brake pads vibrating against the disc and is caused by one of the following :

1. Brake dust collecting between the disc and the pads.

2. Brake linings that are too hard.

The solution is to clean out the brake housing of all brake dust, clean and apply a very thin layers of graphite grease at the back of the brake pads to reduce vibration.

If you find a lot of brake dust (that is common with softer pads), try using a slighter harder pad lining.
