Stopping-distance regs were expected to drive adoption of air-disc brakes (ADBs), but it’s looking like concern over weight may be the bigger driver. “Fuel-economy regulations pose impressive ...
Tractor-trailers don’t stop on a dime. You can blame the realities of physics for that. But a standard 6×4 tractor traveling at highway speeds still needs to stop within 250 feet, which is ...
An object like a tractor-trailer remains in motion unless an outside force like the braking system acts upon it. Even Isaac Newton could have predicted that. And when brake components fail, there’s ...
The following was published in CCJ's Air Brake Book, 11th edition, sponsored by Silverback HD. CCJ's Air Brake Book is a complementary industry resource courtesy of our partnership with Silverback HD, ...
On August 1, 2011 a new air brake standard for three-axle tractors with Gross Vehicle Weight Ratings (GVWRs) up to 59,600 lbs. took effect. This rule applies to tractors invoiced after August 1, 2011.
If there’s one thing on commercial vehicles that operations and maintenance professionals need to understand, it’s braking systems. Not getting a truck to start rolling on time will cause delayed ...
An air brake or, a compressed air brake system, is a type of friction brake for vehicles in which compressed air pressing on a piston is used to apply the pressure to the brake pad needed to stop the ...
Electric cars are known for regenerative braking, so it is easy to assume the friction brakes enjoy a quiet life. The real picture is more complicated. Many EVs place sudden, heavy loads on their pads ...
