Part 2: Warning Signs You Shouldn’t Ignore

If you’re burying your head in the sand about strange noises coming from your brakes, it’s time to face reality. Your brakes are on the way out or about to fail you completely.

The Tyre, Equipment, Parts Association (TEPA), warns ignoring a small braking issue is not only dangerous but will also be more expensive to fix the longer you leave it.

 

“Brakes give warnings - Unlike a fan belt that just snaps or a battery that just dies, brakes almost always tell you they're unhappy long before they fail. They squeal, grind, shudder and ‘feel funny'. Do them a favour and listen,” says TEPA National Vice Chairman, Dylan Petzer. “Any change in pedal feel - specifically spongy, soft or a pedal that sinks to the floor – needs urgent attention. This is, in my opinion, the most dangerous warning sign of all. A grinding brake will still stop you (horribly, but it will stop). A spongy pedal is a sign of impending total failure.

 

“As we covered in Part 1, your brakes work on hydraulic pressure - A soft, spongy pedal means there is air in the brake lines. This could be from old, boiled fluid or a fluid leak somewhere in the system. Air compresses; liquid doesn't. When you push the brake pedal, you're just compressing a bubble of air instead of pushing the brake pads against the disc. One more hard stop or one more bubble and that pedal will go straight to the floor with zero stopping power. 

“This is a sign to drive slowly to a fitment centre NOW – not later!” Petzer warns ignorance is financial doom when it comes to brakes.

 

Here are some dreaded scenarios when ignorance is bliss …

• You hear squealing (wear indicator): You need new brake pads – however, delaying could double or even quadruple your expenses if other components become damaged.

• You ignore grinding noises (metal on metal): You've now destroyed your brake rotors and will be facing costs that could be 100% to 300% higher than just changing the pads alone.

• You keep ignoring the noises: The extreme heat from the grinding metal can damage the brake caliper. You might also panic-stop, warp the new components or worse, have an accident. Continued neglect can even risk severe damage or accidents, with costs rising many times over or resulting in a total write-off.

 

What your brakes are really trying to tell you:

• Squealing is usually the first warning. It's a high-pitched, metallic "squeeeee" that often happens when you first apply the brakes. This is the wear indicator - a tiny piece of metal designed to screech against the rotor when your brake pads are getting thin. This is your brakes begging for some TLC.

• Grinding is the sound of metal-on-metal - your brake pads are completely gone! The metal backing plate of the pad is now grinding directly against your metal brake rotor. This is your car screaming “Stop! You are destroying me and your ability to brake”.

• Shaking (shuddering) is a vibration you feel through the steering wheel or the brake pedal. It means your brake rotors are no longer flat; they are warped, usually from being overheated. Because the surface is uneven, the pads "grab and slip" rapidly, causing that judder. It's your car saying, "I'm compromised! I can't provide smooth, predictable stopping power anymore".

 

If you experience any of these, get your brakes checked immediately.

 

“The festive season is around the corner, so there’s no time to waste in getting your vehicle holiday ready too,” Petzer says. “Ensure your brakes won’t let you down by having them thoroughly assessed for a long trip at an accredited fitment centre - especially if you’ve heard unusual noises.

 

“If your vehicle has ABS, ensure it is functioning correctly as it helps maintain control during sudden stops. Also check the handbrake to prevent unexpected rolling when parked on inclines. 

 

“For total peace of mind, other pre-holiday checks must include the battery, tyres, windscreen wipers, all fluids, windscreen chips or cracks and all lights. Pack an emergency kit that includes items like a first aid kit, torch, extra batteries, blanket, water, non-perishable snacks and basic tools. Having an emergency kit can help you handle unexpected situations and keep you safe until help arrives.”
