If you hear sounds or discern vibration when you brake with your Volvo 121, all this could arise from several concerns. Generally, there is not always to worry, however it always seems essential to pay attention to it and fix this problem. Sometimes, just scrubbing the affected part can work. In this , we will look at how to find a diagnostic depending on the noise, and then what precautions to take.
Whistling noise on your Volvo 121 front or rear brakes
As soon as a noise from whistling occurs with the Volvo 121, it's usually related to brake pads. This manifestation is usually identical in the event that the noise comes from the rear or front brakes. Indeed, the lining of the brake pads will be made of a rubber material, which allows to stick perfectly to the disc. In the event that this component is damaged, the disc may come into contact with the wafer. So this is what friction that produces that hiss you hear. If it is indeed this circumstance, it is essential to change the brake pads. However it is also conceivable that some gravel or something else has slipped into the pads. Also in this situation, a hissing sound may be heard. It also seems necessary to do control by a mechanic so as to check if it could be dangerous. Assuming it's at a squeak that you have to do, it most certainly suffices to acquire a brake cleaner and spray it on the disc of this vehicle.
Braking vibrations on your Volvo 121
All of this vibration when braking can be discerned in several places. Around the brake pedal of course as well as on the valance or on the checkout of this Volvo 121. In most cases, the vibrations are due to a veiled disc. You will be able to see it visually by removing the wheel to reach the disc. Small warning, in the event that it is indeed the disc which happens to be veiled, it is extremely essential to change it quickly, quite simply because it could damage other parts of the direction.
Your Volvo 121 squeaks except when you brake
It is then an opposite problem. When you brake, the brake pads will come into contact with the wheel, shrill noise suddenly disappears. This problem must probably come from calipers. They happen to be way too close to the wheel when you're not braking. This is how this contact produces the noise. Sometimes it will be enough to apply a few hitting brakes so that the calipers are replaced by themselves. In case it does not work, we will have to change them!
Loud noise when braking
If your Volvo 121 produces a thud and metallic when you hit the brake you're likely to get it from your brake pads. As a rule, the wear indicator is normally expected to work. But it also happens sometimes that the latter does not start. In this situation, do not wait and go to a garage. To have some worn pads at this point turns out to be really dangerous. It is imperative to change them.
