PRXB pacbrake exhaust brake

Diesel Exhaust Brakes and Retarders

Diesel engines, unlike gasoline engines, don't slow down simply by taking your foot off the accelerator; they rely on service and supplemental brakes. An exhaust brake is a form of a supplemental brake, and they work much differently than their conventional counterparts.

Pacbrake’s flagship product, the PRXB (pressure regulated exhaust brake), is the unquestioned leader in the supplemental brake industry. The patented PRXB design delivers the strongest braking horsepower, greatest speed reductions and shortest stopping distances possible without the use of service brakes. It maintains optimum retarding performance by maximizing the exhaust backpressure throughout the entire RPM range. Unlike a typical exhaust brake, which requires high RPMs to work properly, the PRXB delivers constant exhaust pressure (braking) as early as 1200 RPM through to the maximum allowable RPM.

Controlled by a master ON/OFF switch, Pacbrake’s exhaust brakes provide whisper quiet supplemental braking that allows service brakes to be used much less, ultimately saving you money. They have the ability to be left on all the time, making it ideal for in-city driving or for steep, downhill grades. This product pays for itself as less wear on the brake pads means fewer brake jobs.

PRXB Exhaust Brakes: Mechanics

With over a quarter of a million exhaust brakes manufactured and sold, Pacbrake has mastered quality product development. Being home to the only exhaust brake on the market with a true variable orifice, remarkable constant backpressure and strongest braking horsepower, Pacbrake has revolutionized modern day exhaust braking with its patented design of the PRXB.


WHAT’S SO SPECIAL ABOUT THE PRXB?

In order to have consistent and effective braking over the entire RPM range, it is important (and necessary) to maintain constant backpressure. To achieve this, Pacbrake’s patented design has incorporated an additional waste gate on the butterfly valve to regulate the amount of exhaust flow that is being passed through. The flow is controlled by a spring-loaded arm, whose pressure rating and location are key factors in the functionality of the PRXB. Located outside of the housing and away from the heat, the spring is able to maintain its strength and durability for years of proper and precise braking performance.

CREATING & MAINTAINING BACKPRESSURE

Backpressure is created by exhaust flow entering the housing, hitting the closed butterfly valve and being forced back out in the direction it came. It is maintained by the pressure-controlled spring that is located on the outside of the exhaust brake housing.

PREMIUM BRAKING PERFORMANCE

As the engine’s RPM increase, the spring compresses and the arm moves away from the butterfly valve, therefore releasing more exhaust flow through the orifice. As the RPMs decrease, the spring releases and the arm applies pressure back onto the plate, covering the hole, and ultimately releasing a smaller amount of exhaust flow.

There is less than a 10% change in backpressure over the entire RPM range on the PRXB

PRXB Exhaust Brakes Kits Everything Is Included

Pacbrake likes to keep things simple for the customer. They provide a total package of quality service and parts. There are a number of components required to operate an exhaust brake and they are conveniently included in their exhaust brake kits. Check out the information below to learn what is included in our kits.

PRXB Exhaust Brake Kits AIR COMPRESSOR, TANK & CURLY HOSE

pacbrake kit

Every exhaust brake requires an air compressor and air tank to operate. Often mounted under the hood, Pacbrake’s air compressor builds up pressure in the air tank that is released during braking.

Pacbrake’s ½ gallon air tank works with the exhaust brake and air compressor to speed up the exhaust brake cylinder activation. It does this by storing air pressure (created by the compressor) and holding it until needed. Outside the air tank there is a 135 PSI pressure switch that controls the amount of air pressure contained inside. As the pressure drops a signal is sent to the compressor to create more air, thereby filling the tank back to its full capacity.

Generally frame mounted, this onboard air tank also provides an air source for operating air horns and air springs (as well as any other air-operated accessories your vehicle may have). PLEASE NOTE: If you are operating more than one air operated product and prefer a larger air tank and/or compressor, upgrades are available.

A 25ft curly hose with an assortment of accessories is also included and easily stored in a heavy duty nylon bag. Just attach the curly hose to the quick disconnect chuck off of the air compressor (your external air source) and you’re able to perform a variety of jobs including:

  • Filling tires and checking air pressure
  • Inflating air mattresses, footballs, beach toys etc.
  • Blowing air (for cleaning, dusting, quick removal of debris)

Dodge Cummins Exhaust Brake

LoadLeash for 6.7 L

load leash 6.7 l

P-67 LoadLeash Engine Brake & Sterling chassis cab trucks. For over 50 years Pacbrake has designed, developed and manufactured engine and exhaust brake solutions for our OEMs and aftermarket customers. Our supply covers some of the largest commercial engine and truck builders in North America all the way to the single truck owner. We pride ourselves on having true market knowledge and an understanding of what our customers need for braking.

It is with this understanding of our market that we committed to a 2 year development project which challenged our engineers to take our current core knowledge and develop an integrated engine brake solution for the 6.7L Cummins engine platform. Well, we have done it!

Pacbrake's P-67 LoadLeash works in conjunction with the factory installed exhaust brake on 2007-2012 Dodge pick-up/chassis cab trucks and Sterling chassis cab trucks.

LET PACBRAKE’S NEW INTEGRATED LOADLEASH™ ENGINE BRAKE FOR RAM HD SHOW YOU WHAT REAL BRAKING IS ALL ABOUT!

FEATURES
Performance; Doubles the supplemental braking power for unmatched load control
Safety; Increases vehicle control and reduces brake fade
Savings; Reduced foundation brake wear for 3x longer brake service intervals
Weight; Truly integrated engine brake solution with minimal weight increases (compared with traditional engine brake applications)
Packaging; Integrated engine brake with no increased valve cover heights
Noise Bylaws; Unlike traditional engine brakes which require expensive mufflers to dampen high noise levels, the LoadLeash™ is virtually silent

LoadLeash™ Engine Brake Mechanics
Electric/Hydraulic Mechanical Activation of Exhaust Valve
Provides a Pumping Loss on Compression Stroke and Exhaust Stroke
Works in Conjunction with Vehicle VGT or Exhaust Valve
Pacbrake’s LoadLeash for Cummins 6.7L engines is a “weeper or bleeder” design engine brake, working in tandem with the VGT exhaust braking feature. It functions by the exhaust valves being held slightly off their seats during the complete engine cycle with the VGT providing backpressure and increased boost pressure.

Two braking strokes are achieved, plus, the expansion stroke is eliminated.
1 Standard braking stroke occurs during the normal exhaust stroke with the piston trying to push cylinder pressure past the open exhaust valve against the “closed” VGT.
2 The second braking stroke occurs during the compression stroke with the piston trying to push cylinder pressure past the open exhaust valve against the “closed” VGT.
♦ Normal expansion stroke after TDC is eliminated by the open exhaust valve.

Results are 50% more retarding horsepower than the VGT alone, as measured at the flywheel.

Air Suspension Spacer Kits

We offer Pacbrake's 2", 4" and 6" spacer kits that are designed to be used with lifted trucks. Use these spacer kits when the distance of the upper and lower mounting locations of the air springs have increased due to installation of a lift kit. The spacers are made of high quality steel and plated in a sleek black zinc coating for added strenth and corrosion resistance.

TIE ROD SLEEVES KIT
GM 2500 HD, 3500 1999-2008

For safety and security, Pacbrake’s stainless steel tie rod sleeves strengthen the stock cast iron tie rods to prevent them from bending and ultimately breaking. This kit is recommended for those who go off-roading, but many may be interested in this inexpensive kit to ensure the safety of their vehicle and passengers.
