Car brake Noises and Possible Causes

Most off our customers who have their car serviced at regular intervals. Can sleep at night because they know that brake problems will be at a minimal. So, compared to the car owners who go from year to year. Without a thought to the condition of their cars. Especially the brakes and tyres. Luckily we have a system that picks up these cars at yearly intervals here in the UK called the MOT test.

This is when the faults and worn out car parts are picked up including the brakes. Including, all the other important parts of the car that need to be kept in tip-top condition for the sake of road safety.

Even so cars brakes do go faulty even in between servicing. Car brake Noises and  problems can occur at any time. Winter time is one time that brake problems can happen. The main cause in my opinion is the salt that we spread on our roads to melt the snow and ice can also cause damage to brake pipes cause and the brake calipers to seize up.

When brake calipers are seized up, this means that the pads are constantly put under pressure onto the discs and usually wear very quickly at one side. When cars brakes are regularly serviced we apply special grease onto the calipers to help them stay free from road debris and salt and keep them from setting solid and wearing out the brake pads and making loud Car brake Noises .

Car Brake squeaking noises

This is a similar thing that happens to older cars that are fitted with brake shoes at the rear. The parts that expand and contract the shoes seize up with shoes constantly sticking on causing rapid wear to occur. Another result of not having your car serviced and brakes checked is the build-up of dust and debris in the brake disc area, this is another possible cause of  Car brake Noises.

We have all seen the horrible black dust the builds up inside your wheels. So, making your alloy wheels look a mess. Of course, these would have been cleaned in a service. Spraying the alloy wheels with a special chemical to keep them in top condition.

This noise can happen whether the brakes are being applied or not. The reason is in my earlier text and is more than often a brake caliper that has stuck on because it has seized up due to not been serviced or after the winter, the latter being the most common cause. The pads or a pad will be stuck against the caliper and due to the heat build-up with friction the brake pads take on a shiny coating on the surface, causing them to give off a high pitch squeaking noise.

 This hard coating also causes the brake pads to become less effective, probably reducing their braking power by 30%. If you hear this noise then you should have your brakes looked at as soon as possible, as brake failure could be imminent.

The most common car braking noises is brake grinding disc.

This is the most common problem that we have in our garage in Halifax UK. Customers come running into the reception. Panicking about this dreadful grinding noise. Thus, coming from the front of the car? Many of our customers think that it is the exhaust pipe that has broken. Dragging along in the road. Thus making this horrific grinding sound. This mainly happens when the brakes are applied.

But in bad cases can be a constant noise. The grinding is due to the fact that the lining of the Ferodo Brake Pads  that stop the car have worn out down to the metal part and are grinding against the metal brake discs.

Once again this is due to lack of maintenance. But can also be between services. On rare occasions we have known a small pebble or stone being trapped in the disc. So, making a similar noise. Generally though it is the metal on metal sound. Caused by worn out brake pads. Usually at the front of the car.

In a perfect World the pads would have been spotted as being on the low side and changed on a service, without causing any further damage to the other brake parts, but after the metal on metal it is usually the discs and pads that are damaged and need changing, perhaps trebling  the cost of repairs.

 Brake warning lights now help us more

Some areas of the country can see much more in the way of brake repair work than others. The main reason for this is the terrain. Here in Halifax we are surrounded by the Pennine hills, a small mountain range called “the backbone of England”. Because of this we all use our brakes more often. Therefore the brakes will wear out quicker. We can get more of our fair share of drivers with Car brake Noises. People who live in say Lincolnshire will use their brakes less. Because the terrain is very flat and the brakes are not needed as much.

One of the good things about modern cars. Of course, is the use of computers and warning lights to pre-warn us of any pending problem. The Car Brakes warning light is one of them. Car brake pads are fitted with a sensor wire. Alerting a solenoid when the brake pads reach a certain thickness. So a warning light will come on in your cab when the pads are getting low. A great idea that I think has possibly saved lives.

This also gives the car owner plenty of time to book their car in to the local garage. Subsequently, to have the brakes fixed before they start to make the dreaded grinding noises.

Car brake Noises to finalise

To finalise it is always a good policy to give your car a regular service. According to the owner’s manual. If you cannot do this for some reason or another. Then have your brakes checked. Of course, before you embark on that important journey.  Or before you hear that dreaded Car brake Noise. Perhaps your holidays so that you know that your brakes are in good condition for your own and other driver’s safety sake.
