When Should I Replace My Brake Pads 

Brake Pads are a part of your vehicle designed to wear out. Brake pad design through the years as they have gone on from Metallic, Semi-metallic and now to a Ceramic Brake Pad. The material and design changes are to help braking, noise and dusting. Now when should you replace brake pads or how do you know when they are needed? There are many reasons to replace them and different signs of needing pads. Here are a couple reasons and signs. 

My Brakes are Grinding 

It is time to stop driving and get the Brake Pads and Brake Rotors replaced now. A grinding noise is a sign that the brake friction material has worn out completely and is grinding your rotors. This will wear away the metal of the backing and the Brake Rotor very quickly and may cause over extension of the Brake Caliper and push out the Brake Piston. This will cause the Brake fluid to leak out and cause no Braking. Grinding is an urgent issue and you should go to your mechanic right away for repairs.  

My Brakes are Squeaking.  

This is a noise that can be caused by Brake Sensors because of the Brake Pads getting thin. This is a sign of needing to replace brake pads. Now theres no way to know how long you have before the brake pads completely wear out so you should probably make an appointment with the mechanic right away to prevent damage to other Brake Parts. Brake squeaks may also be caused by rusting, Improper Brake Friction material and by brake dust. All of these are issues that should be addressed by your mechanic.  

My Brake Pads are Thin 

Yes you should replace Brake Pads. Braking is two parts rubbing together to stop your vehicle. This creates lots of heat that thin brake pads can not handle. When Brake Pads and Brake Rotors get thin and hot they will cause braking issues. Common complaints will be not stopping as quick or a soft brake pedal. The heat will also cause the brake fluid to boil. So when you get under a ¼” or 4mm it is time to get the brake pads replaced.  

No matter what signs you are seeing or if your mechanic has noticed thin brake pads, letting the brakes go to a certain point becomes a safety issue. Brake pads should be inspected by your mechanic every oil change to make sure you will not have a future issue. Remember stopping is always more important than getting going.
