Heat Management

There is only one way to safely stop your vehicle. The dynamics of vehicle braking comes down to converting the energythat your vehicle represents – kinetic energy (mass in motion) – into another form of energy – HEAT. This is preciselywhat the brake system is designed to do. Each brake represents a “heat generator” on the vehicle. The more brakesthere are, the higher the capacity the system has to generate heat – it has the ability to convert more kinetic energy intoheat energy. This is why vehicles designed to carry heavier loads havemore braking wheel-ends.

A vehicle with a loaded weight of 80,000 lbs traveling at 60 MPHrepresents an amount of kinetic energy that is the same no matter whatkinds of vehicles you are comparing. Ultimately, the same amount ofkinetic energy must be converted to heat energy in order to make thestop. Simply put, more brakes means lower temperatures generated ateach wheel end to make the stop. Fewer brakes means highertemperatures to make the same stop.

Heat Is Your Friend

Generating heat is the key to efficient stopping. There are however instances when “unwanted” heat is introduced into thebraking equation that makes the job more difficult. Examples of these are:

Heat Is Your Enemy

• Out of adjustment brakes – if one or more brakes aren’t working properly, the other brakes on the vehicle have to compensate and generate more heat - this leads to imbalanced braking and uneven lining wear.

• Steep Grades – the effort to control speed while going downhill leads to brakes constantly generating heat with little recovery time – this causes brake lining performance to decline resulting in brake fade.

• Aggressive Driving – drivers who wait longer to apply the brakes or drive faster generate higher brake temperatures – a major factor that reduces the life cycle of brake lining along with safety concerns.

• Over Loaded Vehicles – carrying weights beyond brake system design not only sacrifices safety, but also leads to premature wear on braking components including the brake lining.

Haldex High Performance Brake Linings - The Premium Solution

When it comes to high performance braking,it’s all about managing heat. Haldex offers theindustry’s premium solution relative to safeand efficient brake lining performance. TheHaldex specification recognizes and accountsfor situations when unwanted heat becomesa part of your braking equation. This designutilizes premium compounds that areresistant to high temperatures so you can beassured that no matter the situation, heat isbeing managed at an extraordinary level.
