truck brake pads,
Is it better to change the brake pads and brake discs at the same time?
This is one of the most frequently asked questions. The answer is YES.
For example, the brake discs do not need to be changed if the car is relatively new and there is still a lot of disc life left. They absolutely need to be changed if the discs are unevenly worn or badly scored.
Take a look at the braking surface of the discs. There are ridges on the edges of the braking surfaces. The following is a simple illustration
The points that are circled in RED are only points that the brake pad is in contact with the braking surface of the brake disc. If the brakes are in this condition, the braking power is obviously reduced, and it can even cause brake noise.
Braking force is created by the brake pad and brake disc. If one of the two are not in optimal condition, the actual braking potential cannot be achieved.
Brake discs in bad condition can not only cause decreased brake performance but also cause brake noise. FRONTECH recommends changing your discs and pads at the same time.
It is dangerous to drive with over-weared brake discs!
Have you ever thought, “Brake discs do not need to be changed because they are metal, and only the brake pads need replacement.” or, “I don’t drive on the race circuit and I drive safely on the street so I don’t need it.”
Have you ever taken a look at your brake discs?
Either disc surface appearance become LP record disc, or crack started, people think it is time to replace. In fact, brake disc surface worn smoothly, when outer area (edge) rose up time to replace.
Why do brake discs need replacement? The main reasons are ‘friction heat’, and ‘heat capacity’.
What is braking?
When you step on a brake pedal, the brake pads and discs come to gather and causes friction.
By converting the friction energy to heat energy, the car is able to safely slow down.
This is how braking works. The ‘friction heat’ that occurs in the process is important.
Relation between Brake disc / pad
There is a “heat capacity” which brake disc / pad can store.
If new disc / pad heat capacity as “100”, wear of disc / pad progress its heat capacity will be “90” → “80” →”70″ … and so on to reduce.
Then, heat not stored by brake disc / pad will transferred to caliper or brake fluid to create various heat damages.
Decrease of brake caliper rigidity
Early worn disc / pad
Distorted, crack, step worn on disc
Brake fluid vapor lock, fluid leakage from screw
Friction material separation by bending of brake pad back plate (backing plate)
To keep heat damage to minimum level, constant confirmation of disc / pad wear status is mostly important.
Further, we are marketing effective brake temperature indicator sticker detect heat damages.
When do brake discs need replacement?
For the front disc, when either side of the braking surface is worn more than 1mm. For the rear disc, when either side of the braking surface is worn by more than 0.5mm～0.75mm.
Wear limit value (Min. Thickness) is stamped on each disc as “MIN TH OO”
(Note, wear limit differ by part number and be cautious.
Incidentally our SD-disc front has slot shaved approx 0.75mm.
Therefore, when slot groove disappear it is a sign as replacement time.
It is very dangerous to go past the replacement period of your brake disc. Please check the condition of your vehicle’s brake disc.
Listen To What Our Clients Say About Our Brake Pad
There are two main types of brake rotors. These are drilled and slotted brake rotors. If you are planning to buy brake rotors, chances are you will be split between these two types of rotors. Between drilled vs slotted brake rotors, which one should I buy?
In this article, we are going to analyze what these two types of brake rotors are, their differences and which one is the best. At the end of it all, you will decide whether you should buy drilled brake rotor or slotted brake rotor.
Chapter 1: What are Drilled Brake Rotors?
Image of drilled brake rotor source Redline360
Just from the name, you can guess the structure and physical appearance of these brake rotors.
Yes, your guess is right, these brake rotors are drilled and their surface has several holes.
The purpose of the holes is to enhance the overall performance of the car’s brake system.
Also, the holes on the drilled brake pads provide an escape route for the gas and dust that has accumulated in the brake rotors.
Once the gas, water, and dust are eliminated, the brake rotors are expected to deliver above-average performance.
By performance, we simply mean that brake rotor will provide a tight grip with the brake pad.
Advantages of Drilled Brake Rotors
Before you buy drilled brake rotors, it is obvious that you would want to know the two sides of the coins.
What are the benefits of drilled brake rotors over the slotted ones?
Here are the main advantages of drilled brake rotors:
1. Drilled brake rotors have better grip
In terms of performance, drilled brake rotors are known for providing a powerful grip.
This is possible due to the presence of holes.
These holes ensure that there is a greater friction coefficient between the brake pads and the rotor.
- Better performance on wet conditions
Drilled rotors tend to deliver exemplary performance even on the wet conditions.
This is possible because the holes on the rotors disrupt the water coating that may have settled on the brake rotor surface.
But, how does water affect the performance of the brake system
The layer of water tends to form a cushion between the brake pad and brake rotor.
In doing so, it reduces the grip between these two brake components.
3.Excellent heat and gas dissipation
As you apply the brakes of your car, a considerable amount of heat is generated.
The heat is as a result of friction between the brake pad and brake rotor.
Drilled brake pad ensures that this heat is dispersed away efficiently.
The holes ensure that there is no accumulation of the generated heat within the brake components.
Why is this feature important
Poor heat management within the brake system can be detrimental to the performance of other brake components.
It can also make the brake pads to wear out faster than expected.
Although this may sound like a minor issue, we cannot ignore the fact that drilled brake rotors have a cool and sporty appearance.
They definitely look appealing to the eyes.
Cons of Drilled Brake Rotors
The main disadvantage of the drilled brake rotor is they tend to wear down in the grooved cycles.
This wearing pattern can cause some level of vibration as you drive.
The vibrations can be worse if the holes are not well distributed on the surface of the brake rotor.
Chapter 2: What are Slotted Brake Rotors?

Just as the name implies, slotted brake rotors have grooves on the surface where the rotor will come into contact with the brake pad.
Why are the brake rotors slotted?
The grooves provide a surface where the layer of gas and dust will settle.
This helps to relieve the tension between the brake pad and rotor.
Advantages of Slotted Brake Rotors
So, what are the benefits of slotted rotors? Are the slotted rotors better than the drilled rotors?
Here are some of the benefits that you can gain from the slotted rotors.
-Ideal for intense braking
When you brake hard, more air and water is released.
The grooves on the slotted brake rotors can easily sustain heavy braking.
This benefit is usually witnessed on the heavy-duty vehicles and vehicles driven on the rough terrain.
Slotted brake rotors can carry more weight and still retain the same level of performance.
The grooves on the slotted brake rotors are equally distributed across the surface.
This means that the frictional force between the brake pad and brake rotor remains constant across the whole surface.
Constant friction force protects the brake pad from glazing.

Cons of Slotted Brake Rotors
Here are the disadvantages of slotted brake rotors:
-They experience premature wear
The presence of the grooves means that some parts of the brake rotors will bear the brunt of the frictional force.
These parts will wear out faster than other parts.
-Slotted brake rotors have a shorter lifespan
These automotive disc brake rotors have a shorter lifespan than the drilled brake rotors.
The results are worse if they are used together with ceramic disc brake pads.
Chapter 3: Which is the Best Between Slotted vs Drilled Rotors?
Here is a video that summarizes differences between slotted vs drilled brake rotor.
Of the two automotive disc brake rotors, which one is the best?
It all depends on your vehicle and where you drive.
As we have mentioned, slotted brake rotors are ideal for intense driving.
This can be on the racing track, offroad conditions and heavy duty vehicles.
On the other hand, drilled brake rotors are for ordinary driving conditions.
Chapter 4: Buying Brake Rotors from Manufacturer
Just like you can order brake pads online, you can do the same thing for the brake rotors.
The most important thing is to buy from reliable and reputable brake rotor manufacturers in China.

When it comes to the issues surrounding the car’s brake system, the last thing that you will want is to make a mistake.
You need to choose nothing but perfect brake parts.
The brake rotor is an important part of the brake system hence you need to be extra cautious when choosing it.
Now that you know the differences between these two types of brake rotors it shouldn’t be hard to choose one over the other.
While doing so, be careful with where you are buying from.
Choose the best brake rotor manufacturer and you will be sure of walking away with the right brake component.
