Jake Brake Vs. PacBrake
Jacobs Vehicle Systems, often referred to as “Jake Brake” since the patenting of its industry-standard diesel compression braking system of the same name in the early 1960s, and PacBrake are prominent original equipment manufacturers in the diesel industry. Though each company focuses on the design and manufacture of braking systems, their offerings differ in the details.

Company Background
-
Jacobs Vehicle Systems and PacBrake date to 1961, though Jacobs is an American company and PacBrake is Canadian. While each company's products and markets have expanded since its founding, both focus on the design and manufacture of in-engine brakes, a new concept for the trucking industry in the early 1960s. While Jacobs' principal focus began with the “Jake Brake,” a compression release brake of its own design, PacBrake did not begin designing and manufacturing in-house compression release brakes until the late 1980s.
"Jake Brake" Products
-
The Jacobs “Jake Brake” is an exhaust braking system that restricts the flow of exhaust gases to increase back pressure on the engine, providing braking power. Jacobs also designs and manufactures bleeder brakes, which cater to small diesel engines and provide stopping power by holding the exhaust valve open. Outside of brakes, the company's Variable Valve Actuation system helps reduce emissions, maximize fuel consumption and improve transient response.

PacBrake Products
-
PacBrake offers two types of exhaust brakes – fixed orifice, which provides stopping power via exhaust bypass, and pressure regulated, which works in a similar fashion to compression release brakes but adjusts the exhaust back pressure in relation to engine speed. Like “Jake Brake,” PacBrake also offers bleeder, or “weeper,” brakes and compression release braking systems. PacBrake's non-brake lineup extends far beyond Jacobs' – in addition to supplemental brakes, PacBrake offers emissions systems, valves, exhaust system solutions and air management components.
Markets
-
Jacobs Vehicle Systems focuses on diesel truck, tractor and automotive markets. The company's partnerships include Caterpillar, Daimler, Detroit, Hyundai, Mack and Renault. Though its partners aren't as high-profile, PacBrake's market is slightly more expansive. The company offers braking systems and components for diesel engines in the on- and off-highway, military, power generation, construction and marine sectors.
