Should I worry about squeaky brakes?
That irritating screech is how you know it's time to have your brake pads replaced. A thin layer of rust over your brake pads can make a similar squeaking noise, but that will usually go away after a few brake applications. If the noise stays with you, be sure to get your brakes checked out right away.
On cars like these, it's normal for brake squeaking during cold temperatures or around town driving. The pads may even squeak all of the time. However, the trade-off is better braking performance and durability during demanding driving.
Driving with this condition could put you at high risk of brake failure and damage your brake discs that are costly to replace. >> Regular brake maintenance can reduce costly brake failures and keep you safe on the road.
A Sound of Safety: The Built-in Brake Squeak
When the brake pads wear thin, the little piece of metal drags along the metal brake disc, making a high-pitched sound when applied. That sound means you have reached the recommended wear limit and should replace the brake pads.
If your brakes are squeaking due to worn brake pads, you should replace them immediately. You shouldn't drive the car for more than a day or two. The squealers warn the driver that the brakes need a service. If you neglect them, you will impose more damage, which will surge the repair expense.
WD40 should not be put on your brakes since it can reduce friction where it is needed and even break down and damage brake components. While spraying WD40 may temporarily reduce a brake squeal or squeak, it could also cause the brakes not to function correctly when you need them most.
According to RepairPal, a simple inspection should cost from $88 to $111, depending on local labor charges. Swapping out a set of brake pads can cost up to $300 per axle in parts and labor, depending on the model. Replacing rotors costs between $300 and $400. Calipers cost $600 to $900.
Permatex Disc Brake Quiet stops brake squealing by dampening vibration at the caliper/brake pad interface. While providing a tighter fit and allowing for easier disassembly it also protects against corrosion.
You can get anti-squeal shims made of rubber, metal, or Teflon and go between the brake calipers and brake pads. This extra layer will absorb any vibrations and keep your car moving quietly.
A constant squeal when pressing the pedal can often simply be brake pads that are worn down to the wear indicators, where are metal tabs on the brake pads. These tabs are designed to tell you it's time to change the brakes!
How do I know if my front or rear brakes are squeaking?
- While driving, slowly brake and listen out for noise.
- Repeat this step, this time using your emergency brake.
- If you hear a noise while braking normally, it's likely that the issue is with your front brakes. If you hear a noise while using the emergency brake, then it's the rear.
Brake Cleaning Preparation
The cleaner can be used on brake linings, brake shoes, drums, rotors, caliper units, pads and other areas of the braking mechanism while they're still intact.
However, complete maintenance cleaning of your brakes is not doable without removing your tires. The process involves disassembling your brake system, which you cannot do without taking your tires off. In cleaning your brakes thoroughly (all the components), it is best to have a mechanic do it for you.
As described in some owner's manuals, the squealing noise is caused by high-frequency vibration of the brake pads against the rotating disc. Vibration is the unavoidable result of friction generated by the pads as the caliper clamps them against the rotating disc.
Worn down brake pads
The most common reason brakes squeak is that the metal wear indicator on the brake pad touches the metal rotor. This is normal and expected from wear over time, but does indicate you should replace your brakes soon.
If you notice your brakes only make noise sometimes, it might be due to moisture-turned-rust on the surface of a disc or pad. This can happen as quickly as overnight, and there may be some squeal until all of the rust has been scrubbed from the components. Here again, this is nothing to worry about.
