MOORESVILLE, North CarolinaMay 9, 2017 /PRNewswire/ --

Very few four-wheel drive vehicles can claim to be as tough, reliable and dependable as the iconic Jeep Wrangler, a machine that can trace its lineage back to the Willy's Jeep. Now Alcon, one of the most revered names in automotive braking, has introduced a comprehensive brake upgrade kit for the JK-generation Wrangler, including calipers, rotors and pads for both the front and rear axles.


Alcon's kit has been extensively tested and proven to deliver significant, quantifiable gains over factory installed equivalents. The kit offers up to 30% reduction in disc temperature rise, a staggering 26% reduction in pad work rate (leading to a corresponding upswing in pad life) and up to 25% decrease in pedal effort. Impressive stats by any measure, but Alcon's kit is also able to bring other, less obvious benefits to the table. All of which are detailed below.

The kit features Alcon's industry-leading four-piston calipers, all coated in epoxy acrylic paint over an acid zinc finish, a combination that's proven to offer excellent corrosion protection. Front and rear calipers boast ductile iron housings which provide maximum strength and stiffness, plus high resistance to both impact and fatigue. Last but not least, all calipers come with advanced wiper seals around each piston. These advanced seals are resistant to the extreme temperatures generated by hard braking, yet also prevent road grime from entering the caliper itself.


Both the rotors and pads included in Alcon's Wrangler kit offer improved stopping power. The rotors are significantly larger than those fitted by Jeep itself (350×32mm front, 330×22mm rear), and have a larger thermal capacity, meaning you can brake harder for longer without suffering brake fade. The pads included in the kit have been chosen for their increased surface area and long working life which makes them the perfect complement to both the rotors and calipers.

Very much a complete, uprated brake solution for Jeep owners who value stopping capability above all else, Alcon's kit has been designed to make installation quick and easy. It's both compatible with the OE master cylinder and fits nicely behind many 17 in. and larger aftermarket off-road wheels.

Suitable for both on and off-road use, Alcon's front and rear upgrade kit for the JK Jeep Wrangler is available to order now. The kit will be on display at the 2017 SEMA Show in Las Vegas, NevadaOct 31 - Nov 3 (Las Vegas Convention Center, Upper South Hall, booth #35233).

You want to stop, right?: Brake System Upgrades

You want to stop, right?: Brake System Upgrades

Brake system upgrades are a popular performance enhancement. Whether it's to improve the appearance of your vehicle after installing open-spoke wheels, to improve stopping ability on the track or to shorten stopping distance for safety's sake, many brake upgrades result in a larger brake system rotor or caliper, or both. While looking good and filling out the space behind the spokes of your wheels, these larger brake system components pose a challenge to the wheel fitment. Original Equipment wheels installed at the factory were not designed with larger brake components in mind, and rarely allow sufficient clearance in diameter and behind the spokes for a performance brake upgrade. The increased diameter of the brake rotor will often dictate using larger diameter wheels, sometimes as much as 2-3" larger. Because the caliper is often changed as part of the upgrade, consideration must be given to the size and shape of the new caliper, which will encroach on the space directly behind the spokes or face of the wheel. The combined shape of the new rotor and caliper create a profile, which must be measured and compared to the space behind the wheel to determine if sufficient clearance exists. But it's important to remember that larger wheel diameter alone does not assure clearance around the brake components. It's the combination of diameter and profile, or shape of the wheel itself, that determine how much room is available for larger brake components.

In addition to brake upgrades sold as aftermarket components, a number of vehicle manufacturers offer special edition vehicles that come with larger, upgraded brake systems right from the factory. To assure a proper fit over Original Equipment brake systems, AlconKits does extensive on-vehicle measuring to determine which wheels will fit over these brake systems. The clearances are just too close to guess.

Working with wheel and brake system manufacturers, extensive analysis of the product, and hands-on inspection and measurement of vehicles is a complex and labor-intensive process most people don't have time or access to accomplish. But it's what allows AlconKits to determine which wheels are the correct fitment for your vehicle in combination with a brake system upgrade, to ensure proper clearance and performance. 

Ten things you didn't know about brakes

Here are some things we bet many people don't know about brakes.  Did you?

  1. Anti-lock brake systems were first developed for aircraft use in 1929. Automobile manufacturers didn’t officially adopt the technology until 1970 (as an optional add-on to Lincoln Continentals).
  2. The brakes of a hybrid vehicle actually help charge the battery that powers the electric motor. Every time you step on the brakes, the energy that most cars waste is instead converted to electricity for the car to use later.
  3. The power generated by the braking system of even a modest family car can exceed 500bhp (375kW), outstripping the engine output of virtually everything on the road. Take a loaded Quantum for example: decelerating from 80Km/h at 8m/s^2 uses over 410KW of power
  4. Squealing brakes? That’s your brake pads telling you they need to be replaced. Most brake pads have built in metal tabs called ‘squealers’ that are designed to scrape the rotor when the brake pads are worn to minimum safety thickness.
  5. Early braking systems consisted of nothing more than a block of wood and a lever system. When the driver wanted to stop, he had to pull a lever located next to him and make the wooden block bear against the wheel. While this worked perfectly fine for old-school steel-rimmed wheels, the technology had to be revamped when rubber tires came into play.
  6. Brake fluid attracts water like magnets attract metal. Over time, the brake fluid absorbs water from the air, and all of the excess moisture gradually reduces its boiling point, increases its viscosity, and promotes rust and corrosion.
  7. In race use, 400 to 600º C is common on smaller cars. In touring cars and larger race cars temperatures shoot up to 800 - 900º C where the discs will glow red or orange.
  8. Car manufacturers are now developing autonomous braking systems, meaning the car can automatically apply the brakes in emergency situations. According to Thatcham Research, the UK’s motor insurers’ research centre, this technology is the biggest safety improvement since the seatbelt and could prevent 17,000 deaths and injuries every year if made compulsory.
  9. Louis Renault is largely credited with the development of the modern day drum brake in 1902. A pioneer of the automobile industry, Renault went on to invent many other technologies that are still in use today, including hydraulic shock absorbers, turbocharged engines, and “direct drive,” the industry’s first gearbox..
  10. The carbon ceramic discs in a McLaren P1 are coated in silicon carbide—one of the hardest materials on Earth. These specially designed discs can bring the car to a halt from 100 km/h (62 mph) in a distance of just 30.2 metres

Alcon vs. the rest


Why Alcon vs. "Those other guys?"

We get this question a lot.  "Why would I buy an Alcon brake kit vs. Brand X.  They offer 6 piston big brake kits too."  Yes... ...and you can drive a Minivan or a Porsche to work as well.  Only one will put a smile on your face.  So here is why Alcon!

True heat tempered brake discs from Alcon are the absolute best you can buy bar none.

While other companies will forge and machine a disc, very few use the extensive heat tempering process POST machining to relieve the internal stresses on the brake rotor that Alcon does.  Alcon heat treats their rotors for 24 hours after creation. This gives the rotors much more durability over time and longevity.  Our experience with Alcon rotors in the AlconKits GT3 Cup car last nearly 3 times longer over other rotor systems.

This translates into false savings by using cheaper rotors.  Saving 25% on a rotor that you have to replace 3x as often will cost much more money over even a few years.

 Alcon's solid monobloc calipers offer much more stiffness than any other caliper.    Solid caliper construction - Many calipers are limited simply by the fact that design engineers use Finite Element Analysis to determine caliper shape.  This is a manual process used to "Just try this and see what happens" to determine optimal shape and stiffness.  Alcon uses  OSCA which is an automatic set of structural optimization tools to assess all components of the caliper to determine the most optimal shape.   

The solid bridge design does not compromise stiffness for convenience.  Removable "bar" style bridges have a narrow contact point and do very little to add to the stiffness of a caliper.  They simply hold the pads from coming out.  Alcon uses a solid bridge across the caliper that increases the overall caliper stiffness tremendously.

Material usage on the Alcon kits is superior in many ways.  From the selection of the raw material to those used in the various components.  As one example, the Alcon brake caliper brackets are made of high quality steel vs. aluminum.  

We have seen a significant number of failures in the competitors aluminum brackets due to stress, design compromise, and galling of the material.

Drilled rotors and cracks

 It is a fair bet that virtually all drilled rotors will crack.  Eventually those cracks connect and the discs are done.  The process of drilling a rotors introduces starting points for fracture.  Most manufacturers will attempt to alleviate this somewhat by chamfering the holes to relieve the stress.  This only works a little. 

Porsche took it a step further and cast the discs with the holes in to have the metal formed around the hole rather than creating the stress risers.  It works better but still ends up with the same issue. 

The original reason for drilling rotors was to allow gasses to escape from organic pads for better braking, and secondarily to lighten the rotor itself.  With modern compounds there is no outgassing so no need for the holes.  Additionally the same rotor mass can be reduced by proper design.  This is why the Alcon slotted rotor is a much better design.  It allows shedding of water, pad waste, etc.. through the slot without causing stress in the rotor and dangerous cracking. 

Metallurgy also plays into the quality and life of a disc. You can see two discs that look and feel he same.  One will cost $100 and seem like a "bargain".  The Alcon rotor will stop better and last more than 3x longer in race conditions because of the quality of the design and the alloy used.
