How to Eliminate Car Brake Grinding Noise (Step-by-Step Diagnosis)
Have you been hearing grinding noise out of your car brakes ? If yes, then it must be making you identical anxious. It ’ s not lone annoying to hear brakes grinding, but it can besides damage your car further if you keep ignoring this admonitory gestural .braking systemcar braking system Brakes are highly stressed component of a vehicle and it ’ s nothing to worry about if it makes some squeaking sound nowadays and then. ever heard a race car make a screaky noise when brakes are applied gently ? That ’ south perfectly normal for a race car because the high performance sintered brakes have a batch of alloy in them. These brakes are meant to do one thing : To have a very potent morsel on the rotor phonograph record. But regular passenger car brakes need to be make noise free. sometimes we might hear screaky noise now and then which is normal.

This is specially noticed when a cable car is driven after a long clock and brake rotors have some rust sediment on it. This corrode will clear out soon after the first base few brake applications and it ’ randomness nothing to worry about.

however, grinding noise while braking needs immediate attention. How to check it ? Drive your car at regular accelerate and brake all the means to halt ( please ensure to do it in a safe environment ). If grinding continues even as you increase brake coerce, then you need to look far into it .

What causes Brake Grinding Noise?

The most likely suspect of brake grinding sound is worn out brake pads. That ’ south why it ’ s recommended to stop immediately and inspect the issue. If you can ’ metric ton figure it out then drive lento to the nearest car machinist. That said, the grinding sound can besides come ascribable to other reasons. Let ’ s discourse all possible probabilities :

1) Used up Brake pads

As I mentioned before, the grinding noise from the brakes frequently comes when the brake pads are completely worn out. A few millimeters thick braking material is fused on the metallic backing plate .brake pads new vs used When the braking material is completely shoe, the bet on home plate is pushed against the rotor. As you can imagine the metal to alloy contact is quite rough on rotors. You decidedly don ’ t want bare metal scraping on the bracken rotor .brake pad wear If you keep driving like this, first you ’ ll lose most of the brake performance, you ’ ll wrong the rotors, and you could besides damage the brake calipers if you keep driving like this for farseeing. Keep reading if your brake pads are very well and you ’ re still hearing a grind randomness .

2) Foreign object stuck in the Braking System

Brake rotors and calipers are exposed to dust and grim all the time. But that ’ s absolutely normal. however, sometimes a big pebble or some other foreign object could get stuck in the brake system and rub against the brake rotor. This problem can be easily fixed by taking something like a screwdriver or even a blackmail washer to pry out the alien object .

3) Damaged Brake Shims

Brake slog shims are made out of metallic element and help keep the brake pads in perfect position in the caliper. They besides make the brakes randomness unblock. These shims can sometimes break and start dragging against the rotor. And that ’ s when it ’ ll make the brakes noisy. Most people keep using the same shim for years and never replace them with brake pads. however, one should inspect shims every time brake pads are replaced. If you notice some wear, replace it with modern shims and don ’ thymine expect for it to break and start causing problems .

4) Worn out wheel bearings

When bicycle hold wears out, it will make a grind reasoned even when brakes are not applied. however, the noise can increase when you apply brakes. That ’ s because while brake, the bearings have to handle excess military unit. For the same reason, you ’ ll besides notice that grinding randomness will besides come while taking a turn .

Other kinds of Brake Noise and why it happens?

1) Squealing Noise due to using Racing brake Pads on public roads

Some driving enthusiasts want the best brake embroider for their daily ride. This is highly admirably as good brakes only add to the safety. But don ’ t make the mistake of using track use only brake pads on public roads. These brake pads have batch of metal in them. On a racetrack, the brakes operate very high temperatures and that ’ s when they perform well. Yes, they wear off rotors quicker but that ’ s the cost of excellent brake. The problem arises when you use them on the streets. These pads will constantly make squeaking randomness and won ’ metric ton extend effective brake performance because they never reach optimum temperature on the street drive .

2) Brake pad wear indicator rubbing on rotor

Most cars have brake slog clothing indicator. On german cars, it ’ s an electronic system that flashes warning on the dashboard when the wear index contacts the rotor. In other cars, it ’ mho equitable a piece of metallic element that rub against the rotor and make a whine noise. Don ’ triiodothyronine ignore this warn message because if you do then you ’ ll be hearing grinding noise soon when the brake embroider material completely wears off .

3) Unlubricated Caliper Guide Pins

Everytime you press on the brake, the brake pads move ever so slenderly second and forth over the caliper lead pins. Therefore it ’ s recommended to add a tap of brake grease on the guide pins. This reduces the friction so that brake pads glide smoothly over it. Most mechanics skip this dance step and even then the brakes remain randomness exempt. But adding a layer of high-temperature grease is a good hindrance quantify. apart from that, the dirt besides reduces the wear on the pins .

4) Clunking or Thumping Brake Noise

This kind of noise is most likely ascribable to a pause issue preferably than a brake problem. When you brake the car nosedives and then comes back up. This can cause things like bad tittup or shocks to make a clop healthy. even fall back brackets that holds cables can be the perpetrator. You might need these tools to work on your car Hopefully, now you are able to figure the campaign for your brake noise. If you have anything to add please comment down below.

Is it safe to drive with grinding brakes?

No. the grinding sound coming from brakes is definitely a sign that you should drive slow and get them checked for brake pad wear. Squealing sound on the other hand, is normal for high performance sintered brake pads.

Can you keep driving with worn brake pads?

Yes you can, but shouldn’t. Apart from being dangerous, it can also damage brake parts like rotors and callipers. $50 brake pad vs $500 brake parts. You choose.
