It really depends on what kind of noises the brake pads are making.
- Typically when your brake pads make loud grounding sound when you press the brake pedal, most commonly caused by contact of the rotor disc with the caliper.Worn brakes should be replaced on time because it might cause much bigger problems.
- Also, in other case if you hear a hissing noise when you press on the brake pedal you might have to check your brake fluid and if it leaks from some place.In most cases that is not the problem, but the noise is caused by air being sucked via a cracked O-ring or silencing foam.The main problem in this case will be replacing the brake buster.Do not ignore this problem as it might cause losing your breaks and ending up in bad position.
- You might also hear a rattle noise,this is most common issue when going over bumps. If it is present all the time when driving, then it may not be brake issue. This might be an issue with your suspension or your shocks.
And if the rattling noise is only present when you brake, then it’s most likely a brake issue.
There are two possible sources of a rattling noise in the brake system:
- Brake Pad Rattling
Replace the hardware on your brake system every time you do a brake job. Hardware like abutment clips and anti-rattle clips allow your pads to slide when you press the brake pedal.
If you don’t replace or use the hardware during a brake job, the pads are likely to move around in the bracket. This can be a source of rattling noise when braking.
- Caliper Rattling
It is important to make sure that your caliper is operating correctly. Is everything tightened down to specifications? A loose caliper bolt can cause a rattling noise.
Are the rubber bushings still intact? If the rubber bushings wear out, the caliper slides will make contact with the caliper. This can be the source of a rattling noise.
