What are cross-drilled disc brakes?

Cross-drilled disc brakes

Disc brakes are now the industry standard for all four wheels of modern automobiles. Rarely are drum brakes utilized for anything besides parking.

Even in relatively small vehicles, the moving masses and engine performance of modern cars are too high for simple drum brakes to provide sufficient stopping power for safe driving.

The issue with every set of brakes has a name: fade.

Strong brakes to help prevent tire fade

Fading describes the reduction of braking power brought on by heat buildup in the braking system.

It can be risky if the heat generated by the friction of the brakes is not dissipated quickly enough: The brake disc temperature approaches the point of melting, and there is a considerable reduction in the amount of friction between the brake linings and the disc.

This could result in the drum brakes on your automobile entirely failing. On the other side, fading can also be caused by simple, solid, holeless brake discs.

In this case, the ineffective dissipation of the built-up heat is another contributing factor.

Brakes with drilled discs

The brakes that come as standard on a vehicle are generally adequate for stopping the car in normal driving conditions.

Automakers consider a variety of considerations while developing a vehicle, including potential limit scenarios. One example of this is a long descent.

The steel used to make brake discs has a melting temperature of 1400 degrees Celsius. To get to such a place, one has to slow down for a significant amount of time.

As a result, contrary to what was previously stated, a momentary braking system failure observed during “normal operation” is not usually caused by “fade.” In such a scenario, there is a problem with the hydraulic system because there is a flaw in the system.

In the simplest scenario, the brake fluid has become stale and has become contaminated with an excessive amount of water.

A test strip can be used to determine this information. However, this test is no longer necessary if the brake fluid has already turned green.

Instead, the brake fluid should be changed as soon as possible, and the brake system should be completely vented. Another possible explanation for a sudden drop in braking pressure is a crack in the brake pipe.

Therefore, it’s become unsafe, do not be afraid to look for the cause immediately.

As soon as the car is operated according to its intended purpose, the brakes shouldn’t be impacted by the factory design.

The heat increases in intensity with increasing speed.

On the other hand, if you like to push the car to its limits and take it around racetracks, then the standard one-piece brake disc will most likely reach its limits sooner rather than later.

When it comes to the brakes, the cooler you can keep them, the better.

As a result, engineers are working around the clock to enhance the braking effectiveness of cars utilizing cutting-edge discs.

One possible route to take to get there is the drilled brake disc.

There’s More to Drilled Disc Brakes Than Just the Holes

It is unrealistic to expect that drilling a few holes into a single-piece brake disc will impact its performance. You will have to break the user’s heart in this particular instance.

Proper heat optimization of brake disc production necessitates a higher engineering proficiency.

The drilled brake disc will typically replace the internally vented brake disc in the following evolutionary stage.

There is also a type of brake disc made up of a single piece and features some slight optimization in the form of slots and holes.

They are only homologated for the rear axle, though, and their primary purpose is optical instead of mechanical.

Because of this, it is guaranteed that it is impossible to tell them apart from heavily loaded front axle brake discs.

A very sophisticated component is the braking disc with an internal ventilation system. Air is taken into the hub while cycling and discharged from the brake disc through channels.

This is how it is designed. The heat that has been built up is dissipated as the air is forced to pass through the hot glass.

Even without any perforations, brake discs with internal ventilation are still quite effective.

On the other hand, if the brake disc is perforated in precisely the right places, then several good things will transpire:

– The ability to dissipate heat has been enhanced.

– The amount of abrasion that the brake pads experience has been optimized.

– The weight of the brake discs has been decreased.

The entire automobile takes on the appearance and demeanor of a more athletic and active performer.

However, even the most complicated brake discs, which have holes and are internally vented, are made of gray cast iron.

As a result, you can get them for a surprisingly low price these days.

Disadvantages of drilled brake discs

It is difficult to believe that drilled brake discs can also have drawbacks, given all of the benefits they already provide; as a result, it is difficult to believe that they can.

Sadly, however, the same can’t be said for these forward-thinking components. Where there are lights, there will always be shadows.

The increased wear on the brake linings caused by the use of perforated brake discs is the primary disadvantage of these discs. Compared to a smooth, one-piece brake disc, a perforated brake disc’s textured surface functions similarly to a rasp, making it significantly more efficient at removing brake pads.

If you want to install perforated brake discs on your vehicle, you should be aware that doing so will require you to replace the brake pads on your car almost twice as frequently as you would otherwise.

Fortunately, most modern vehicles nowadays have relatively simple preventative maintenance procedures that may be rapidly learned.

A brake disc that has been drilled is a component subjected to high stresses and has also had its structural integrity compromised.

High standards of production and design are so required.

As a result, those interested in exploiting this dynamic and valuable feature should never save on the wrong end.

Only trusted companies with a strong reputation should be used to acquire brake discs with perforations.

Keep a watchful eye on the route you are traveling.

  • The following applies to brake discs with internal venting: It is of the utmost significance that they are appropriately put in place. Air is sucked in on one side of the hub and expelled to the surrounding environment on the other.
  • On the other hand, the precise opposite occurs when the sides are mixed up: First, cold air is sucked in on the brake disc’s exterior, heated as it travels through the disc, and then the air is exhausted concentrically inward into the hub.
  • Because of this, a rapid buildup of heat can occur in the region of the brake caliper, the CV joint, or the articulating mounts. These parts always have a large proportion of rubber because of the constant high temperature, which quickly deteriorates and becomes pliable over time.
  • Whether or not the brake discs have holes drilled, the installation and conversion processes for making internally vented brake discs are identical. AlwaysBefore beginning the installation process, ensure that you have read and fully comprehended the instructions in their entirety before even removing the first screw. This will almost certainly result in the correct repair and the desired improvement in performance for the automobile.
