3 Reasons For Squeaky Brakes

3 Reasons For Squeaky Brakes

The importance of the brakes on a car cannot be over estimated. That’s why they are critically inspected when a vehicle goes into a car servicing garage for the MOT test, for example. Modern cars are powerful and the roads are busy; brakes that slow a vehicle instantly in a straight line without drama are vital but it is easy to become complacent and ignore the vital signs that something is not right.

A car that pulls to one side under braking or has brakes that seem to grab for example, or when the pedal feels soft and spongy. That’s the time to get the brakes serviced at your local garage.

Unusual noises also tell a tale but all brakes make some noise sometimes. From startup, especially in cold or wet weather, there may be some minor noise from the brakes as the pads and disc heat up and dispose of any accumulated moisture. Similarly, a car that has been standing might have rust on the discs. This is usual and is quickly cleared when the brakes get going.

Beat The Squeak

A squeaky brake can stop a car just like a perfectly functioning set can but that doesn’t mean it should be ignored. What causes squeaks or squealing noises though? Most modern mainstream motors have brakes that use a cast-iron disc squeezed between two brake pads lined with friction material. Prestige vehicles or top-end sports cars may feature ceramic discs but in the main all cars have discs of steel. So what are the causes?

Worn Brake Pads

When brake pads become worn then it’s time to replace them; a relative straightforward operation. It’s hard to know just from looking if they are on their last legs which is why brakes have wear indicators that will start to squeal as a way of warning the driver that time’s up and replacement is immediately needed.

The Glazing Effect

This phenomenon is another issue that needs to be resolved at once. Glazing happens when the brake calipers get stuck and cause the brakes to bind and remain slightly applied all the time. Not only does this impede performance, although it might not be noticed, it will also reduce fuel consumption and wear the brake components more quickly. The friction from this fault can generate heat that causes the brake pads to harden which is when squeaking can occur.

Cheap Components

What price road safety? DIY motorists who can service their own brakes may be tempted by cheap imports: Don’t be. Similarly when asking your local servicing centre to attend to the brakes, ask them to ensure quality components are used, even if it costs a little more.

Budget brake pads have a higher metal content. This means the brake pads may have a surface that drags on the disc. Another cause of squeaking noise.

Don’t Leave It Until Later

Squeaking brakes do not necessarily mean that components have to be replaced. They may be an identifiable reason that may only need an adjustment or some lubrication. The likelihood is though that the pads are getting too worn or the disc surface is scored by faulty pads or calipers. Either way, action is needed, pronto.

Don’t leave brakes issues until later. Problems with vehicles generally occur when they are least expected or at a financially difficult moment. That’s the nature of life; but there can be no shortcuts. Brakes that squeal or are not functioning as they should must get immediate attention. To leave it until later could mean it will be too late.
