It is not uncommon for customers to have questions when it comes to making a purchase such as new brakes for your car. Below are a list of common questions from our customers. If you cannot find the answer to your question here, we encourage you to contact us directly so that we may be as much as help as possible.
Will I experience brake noise with DRT brakes?
There are many factors that can contribute to abnormal brake noises: improper installation, low quality brake pads, defective calipers, and hardware.
Is the rotor directional?
Rotors with straight or pillar vanes are non directional. Direction of cross drilled or slotted rotors can be installed on either side as long as the front and rear match.
A curved vane rotor is directional and must be installed as left and right. The vanes sweep backward from the inside running back toward the rear of the car. Some models have single side curved vanes, such as Mercedes-Benz. When installed, the vanes will run in opposite directions, this is designed to reduced harmonic noise. Drilled or slotted patterns will run opposite.
How long does the rotor last?
An exact life of the rotor cannot be given due to the fact that many factors will determine how long your rotors will last. Vehicle weight, personal driving habits, vehicle usage, brake pad material, etc. all effect the lifespan of your vehicle's rotors. Rotors must be replaced when they fall below the minimum allowed thickness.
What is the Bed-In Process?
When replacing your rotors or brake pads the products should always undergo a process known as being "bedded in:"
- Drive the vehicle between 35MPH-40MPH lightly apply brake pedal to a complete stop.
- Repeat process for 8-10 times.
- Avoid heavy braking for the first 200 miles, unless in a situation to avoid an accident.
Why do some discs have more holes than others?
The number of holes that appear in a cross drilled rotor is a large part of the engineering process. The size and number of vane also dictates the pattern and number of holes to appear on the disc. Too many holes in a rotor will cause a reduction in the friction surface. Each DRT rotor is designed for maximum performance and stopping power.
What is Powder Coating?
Powder coating helps prevent rust. Powder is applied to the center hat and outer edge. Friction surfaces are not coated.
Why use drilled or slotted discs?
The benefits of using drilled or slotted rotors over stock or OEM rotors are many:
- Rotors with drilled holes or slots can help to clean and refresh the pad surface, as well as, provide increased brake bite.
- Cross drilled or slotted rotors help prevent gasses from building up and collecting between the pad and rotor surface.
- Slotted rotors are the strongest; there are no drilled holes and brake bite is far more aggressive.
- Cross drilled rotors are brake pad friendly.
- Cross Drilled/Slotted combination is the best of both worlds. They are aggressive, yet very complementing for the wheels.
Do my DRT brakes come with a warranty?
Design Rotor Technology offers a one year warranty against any manufacturer defects. Design Rotor Technology does not cover products damaged due to improper installation or mishandling. Any warranty exchange is to be determined by Design Rotor Technology. Cost of shipping to return a defective product is the sole responsibility of the customer and will not be covered by Design Rotor Technology.
