FAQs—Mitsubishi Brake Disc and Pad Kit
- How long do brake pads and brake rotors typically last? I just got a new Mitsubishi brake disc and pad kit and would like to know the average lifespan of these brake components.
Brake pads can last anywhere between 30,000 and 70,000 miles. As you can see, brake pad lifespan is estimated at a wider range. This is because the condition of the brake pads will depend on a long list of factors. These include the type of brake pads and rotors used, your driving style or habits, the road condition, driving situation, and the weather, among other things. If you drive more aggressively or are more prone to hard braking, the pads will naturally wear out faster, for instance. Brake rotors or discs last much longer than the pads, up to 3 times longer. But like the pads, these are subject to the same conditions. Brake maintenance will also be a factor here. If the pads are replaced before they wear out severely, rotor damage can be prevented, for example.
- When should the rotors or brake discs be turned? Is this a better option than just replacing the old discs or getting a new brake disc and pad kit?
Brake rotors may wear out unevenly. This can affect braking performance. The rough surface can be smoothed out and can become parallel or straight through machining or resurfacing. When the discs are turned, a small part of the metal surface is shaved off through the lathe. This will give you an even surface for even better pad wear and improved braking performance, but will thin out the discs. This is why the discs can only be turned a certain number of times, even if others recommend turning during brake service or brake pad replacement. You have to be sure that the discs are still within the preferred thickness, as specified by the manufacturer.
Turning is done since replacing the disc is more expensive than changing the pads. If you have the budget, it's always better to just replace the warped or damage rotors or to get a disc and pad kit if the pads are also due for replacement or have caused the rotor damage. Turning can shorten the life of the discs and can reduce heat dissipation in the process, which makes the discs prone to brake fade and overheating.
- How can the braking performance of my vehicle be significantly improved? I'm shopping for a new disc and pad kit for my Mitsubishi. I want to know what I can do to increase the braking power and response.
Better brake pads can have a huge impact on the performance of the brakes. Brake discs that are designed for increased cooling will also help. You can always upgrade your vehicle's brake system. Other than better pads and rotors, better tires also help improve the vehicle's braking response with better tire-road contact and traction.
- What are the advantages to using drilled and slotted brake discs or rotors? Which is the better option?
Slotted and drilled brake rotors are already an upgrade to the standard brake discs. Both offer improvements in performance with better heat dissipation. The slots on the discs allow the rotors to cool faster than usual as hot gases can easily escape. The design allows better pad contact and lets water to escape easily when driving in wet weather. Cross-drilled rotors, meanwhile, offer up to 40% better cooling capacity, which improves braking significantly, especially in wet weather conditions.
The better option for you would depend on the type of vehicle you drive and your driving style, among other considerations. Slotted rotors are recommended for heavy-duty use because of their structural strength. Drilled rotors, on the other hand, are known for greater heat dissipation and enhanced initial bite and responsive braking performance. These are used by many street vehicles as upgrades, including sports cars.
- If I switch to cross-drilled or slotted rotors, do I need to use special pads?
Any type of pads can be used. Upgrading to better pads isn't exactly a requirement. But if you switched to cross-drilled or slotted rotors for improved braking response and performance, using higher-quality pads would be best to achieve these results.
