Grinding noise coming from the front brakes of Swift Vxi when rolling back

[vivekchugh]

I recently bought a swift Vxi which has done 4000 kms. I noticed a grinding noise coming from the front brakes when rolling back slowly on an incline from standstill. This happens only when rolling back when I press the brakes slowly. Can anyone tell me is this is normal?

What you are experiencing is normal. This usually happens when the brakes are cold or after you have driven through water or washed the car.

Recently changed the disc pads ?

OR

Did the A.S.S opened the brakes ?

If this happens only when in reverse, it's not normal.

That's a non-issue. A grinding/grating sort of noise is expected when the discs/drums rub against the pads/shoes in the wrong direction (reverse), because they are not bedded in for full grip in that direction. Even a little moisture on the pads/shoes can produce that kind of noise.

If you don't get any noise while braking during forward movement, don't bother.

I admit that the grinding/grating sort of noise arises when the discs/drums rub against the pads/shoes. But the noise would be there irrespective of the direction !

Then, Why this happens only during reverse ?

This happens on my i10 also. It is a common problem. When you take reverse in an inclined slope you get a "tak tak tak" sound. I have got the same sound. I would suggest, you compress your cluth completely when you take reverse. The problem is, when you take reverse in a slope, without the cluth being depressed, the back breaks come into effect countering the movement. Hence, I suggest you press your clutch completely when taking reverse in a slope. I tried it and I do not get the noise anymore.

Because the pad/shoe material, which sometimes has fine metallic fibres embedded in it, beds in, in the direction of use - forwards. When braking in reverse, the grip is not even, so the disc/drum stops in a jerky fashion, generating the noise. Can also sometimes happen going forwards - not as frequently though!

Q: Sometimes my brakes make a grinding or groaning noise that only happens at very low speed stops. Are my brakes going bad?

A: Only a complete brake system inspection by a competent brake specialist can give you the truth, however the particular noise you are describing is generally considered normal, particularly on vehicles with semi-metallic pads or most front wheel drive cars. The noise is simply a vibration that can be more felt than heard coming from the front disc pads because on slower stops you don't have the brakes applied fully which allows them to vibrate against the rotor surface. Usually no service is required as the noise is unavoidable, however if the noise is constant and occurs at almost every stop, the brake system should get immediate service.
