Common Causes For Squeaking Brakes
Author: Toby Date Posted:4 November 2024
The only thing that’s more annoying than squeaky brakes, is trying to find out why the damned things are squeaking in the first place. Whether it’s a loud screech or a soft whine, brake squeaks are usually a tell tale sign something is up with your braking system.
Lucky for you we have plenty of experience with brake issues at Superspares and have created the ultimate checklist to get your brakes sounding smooth in no time.
Common Reasons & Solutions for Brake Squeaks
1. Worn Brake Pads
The most obvious cause of squeaking brakes is brake pads that are overdue for a change. When your brake pad material completely deteriorates you’re left with the metal backing plate which will make a loud screech when it comes into contact with the rotor. Not only is this bad for your eardrums, it will dramatically affect your braking performance and cause damage to your brake rotors. The last thing you want is metal on metal left on your brake pads when you’re in a critical braking situation.
Replacing your shoddy brake pads is a surefire way to eliminate annoying screeches. You can do this yourself if you're up to the job, or have a mechanic take care of it so you have someone else to blame if it goes wrong. Make sure you’re replacing your brake pads with a good quality brand such as Bosch, Bendix, Brembo or BCP as cheap brake pads may give you a new noise to complain about.
2. Incorrectly Fitted Brake Rotors or Pads
Improper installation of your brake parts can also result in squeaking despite your brake rotors/pads being brand new. There is nothing more frustrating than installing a new set of brake rotors or pads only to still experience your brakes squeaking while driving. All it takes is a single component from the brake pads, rotor or callipers to be misaligned to create the dreaded brake squeal.
Don’t ask yourself DIWHY did I do this to myself and get your brakes installed by a reputable workshop if you’re not confident in doing the job yourself. Additionally, during the brake pad installation ensure you follow the proper bedding-in process otherwise you may be stuck with a new type of squeal.
3. Warped Brake Rotors
If your brakes become too hot to handle, the cast iron surface will become malleable making the surface of your rotors uneven. Uneven rotors will lead to inevitable vibrations and squeaks as your brake pads are designed to engage into a flat surface. The uneven surface may not even be perceivable to an untrained eye but make all the difference when it comes to stopping.
If your rotors are warped you’re now in the market for a fresh set of brake rotors. Stick to a reputable brand such as Brembo, Bosch, or BCP. Also consider Slotted Performance rotors from DBA which have advanced heat dissipation if this isn’t the first time your rotors have warped. You could be asking for more from your brakes than they’re capable of if you’re towing or running performance upgrades.
4. Brake Dust and Debris Buildup
Your vehicle’s brake pads are constantly creating metallic dust every time you brake which can get trapped in your calipers or between your rotors and pads causing squeaking sounds. Pesky dust and debris are an overlooked reason for brake noise due to how imperceivable dust is and the brake system needing to be pulled apart to check.
If dust is the cause of your annoying brakes you’re in luck as it’s an easy DIY friendly fix. Simply remove the wheels and clean your braking components thoroughly with brake cleaner removing all dust to clear the way for better friction.
5. Lack of Lubrication
Your braking system is not built to go in dry. Caliper pins, pistons and brake pad backing plates need to be lubricated to function quietly and efficiently. Without sufficient lubrication, metal-to-metal contact may occur, causing a squeaking noise.
If you or mechanic forgot to lubricate your brakes on installation it’s not the end of the world. You’re just going to have to pull the brakes apart again and ensure the above mentioned components are lubricated well with brake grease.
Trust Superspares for Quality Brake Parts and Maintenance
The final diagnosis? Squeaky brakes are a symptom with varying degrees of concern. It could be a simple sign of built up dust which certainly isn’t a critical issue if you can put up with the noise. Additionally it could indicate your brake pads are in an urgent need of change.
You’ll generally be able to distinguish more concerning brake screeches from one another but never hesitate to visit your local mechanic if you’re after some peace of mind. If you are changing your brakes, make sure to visit Superspares for brake parts you can trust.
