How Often to Replace the Brake Discs？

Brake discs should generally be replaced when they are worn down beyond a certain thickness or if they are damaged. The frequency of replacement will depend on a variety of factors, including your driving habits, the type of vehicle you have, and the quality of the brake discs.

It is a good idea to have your brake discs inspected by a mechanic at least once a year to check for wear and damage. If the brake discs are worn down to the minimum thickness recommended by the manufacturer, or if they are damaged in any way, they should be replaced.

The rate at which brake discs wear down can vary significantly depending on your driving habits. For example, if you frequently drive in stop-and-go traffic or do a lot of heavy braking, your brake discs may wear down more quickly than if you primarily drive on the highway. Similarly, if you drive in adverse conditions such as in heavy rain or on rough roads, your brake discs may wear down more quickly.

It is also important to use high-quality brake discs that are designed to withstand the demands of your driving habits. Poor-quality brake discs may wear down more quickly or be more prone to damage, which could result in the need for more frequent replacements.

In general, it is a good idea to follow the manufacturer's recommendations for brake disc replacement, as they will be based on the specific needs of your vehicle. If you are unsure when to replace your brake discs, it is always a good idea to consult a mechanic or refer to the owner's manual for your vehicle.

we Recommend That You Replace Your Brake Discs when

1. Vibration when Braking

When the brake pads or rotors are going bad, it’s common to feel a vibration in the brake pedal. When it gets really bad, the vibration will also extend into the steering wheel. 

Often this vibration comes from brake pad material that has collected on the face of the rotor, creating high spots. In some cases, it occurs when the brake system becomes overheated from excessive use. You may also notice more pedal feedback when the deposits build up. 

2. Cracks

After the rotors are subject to excessive heat, the surface can crack. While there are multiple different types of cracks that occur, they are all related to either compression or expansion. 

Small hairline fractures might seem alarming, but in many cases, these can be repaired with resurfacing. You will most often see the hairline fractures when using the brakes at high temperatures, such as if you are racing. 

However, a crack that occurs on the rotor and extends to the edge will require immediate replacement. There is no fix for this type of rotor damage. 

3. Damage/Grooves

Over time, the surface of the rotor can become grooved and damaged. This is caused by debris or worn components rubbing against the rotor. 

If the metal backing plate from worn brake pads makes contact with the rotor, it can cause damage. Also, corrosion and rust will create grooves on the surface.
