Make sure your brakes remain in good condition by: Ignoring brake issues (big or small) can lead to breakdowns and accidents - which may mean extended periods of downtime and loss of revenue. Whether your vehicle has drum brakes, disc brakes or both, it’s important to maintain them on a regular basis. Manufacturing a vehicle like this is considered ideal because it provides the necessary stopping force in the front, but helps reduce costs in the back. To help offset costs and provide the benefits fleets are seeking, many manufacturers have found it ideal to use both brake types - discs on the front wheels and drums on the rear wheels. ![]() Even though performance is a priority for many carriers and drivers, the added cost can lead many to choose vehicles equipped with drum brakes instead. While disc brakes do have faster stopping capabilities, they’re more expensive than drum brakes. Resistant to wet weather (because they are fully exposed, water and debris can get off the rotor to help with performance).The rotor is fully exposed to outside air (this helps keep it cool).Easy inspection (wheel doesn’t have to be removed).The power screw then clamps the brake pads down on both sides of the rotor, causing friction to build up and stop the vehicle. As the pedal is pushed, compressed air travels to the brake chamber where the eccentric lever activates the braking force. When the wheel is in motion, the rotor spins with it. The primary components of disc brakes include the brake chamber, eccentric lever, power screw, brake pads and rotor. When heat builds up, it causes the drum to expand and creates more pushrod travel, which can impact stopping ability. This happens because the components are housed within the metal drum with limited air circulation. While drum brakes have many benefits, they do have one downside - overheating may cause increased stopping time, which is called brake fade. Inexpensive construction and installation.Clean operation (free of dirt and other road debris since it’s enclosed).Once the pedal is released, the return springs pull the shoes away from the drum back into resting position and allow the drum to resume rotating along with the wheel. The created friction causes the wheel to stop moving. As the lining rubs against the drum, kinetic energy (wheel movement) is converted into thermal energy (heat). The rotation of the camshaft allows the rollers to spread the shoes apart and force the lining against the drum. This forces the push rod to actuate the slack adjuster, which rotates the S-cam. When the brake pedal is pressed, pressurized air (stored in air reservoirs) travels to the brake chamber. Drum brakesĭrum brakes are composed of the brake chamber, push rod, slack adjuster, S-cam (camshaft), rollers, shoes, lining, drum and return spring. Learn how each type functions and their advantages and disadvantages. Comparing brake typesĭrum brakes and disk brakes function similarly (turning kinetic energy into heat), but the way heat builds up when friction occurs is the primary difference. Commercial vehicles have air brake systems that are equipped with drum or disc brakes (or both) - the information below can help you understand each type. We are a Canadian company that is privately owned with locations across Canada.Did you know it usually takes the length of two football fields for a semi-truck traveling at 65 mph to stop moving when brakes are operating normally? Because big rigs have longer stopping distances, it’s important to understand the different types of brakes, how they function, and how to maintain them so you can drive and stop safely.In addition to our online parts store, we have 17 brick-and-mortar retail locations across Canada so you can be confident when you buy from Maxim Truck & Trailer.Shipments arrive at your door within 3-5 business days via Canada Post Expedited Parcel Service. ![]() We usually fulfill orders within 12 hours from the business day they are ordered.
