Worldpac, a wholly owned subsidiary of Advance Auto Parts, celebrated the grand opening of its newest warehouse on Feb. 22 in Hatillo, Puerto Rico.
Members of the local community, including Hatillo Mayor Carlos Román Román, attended the ribbon-cutting ceremony.
Located at H-1 Metro Plaza Hatillo, Carr No. 2 KM 87.5 Marginal, Worldpac’s Hatillo warehouse measures more than 30,000 square feet and has the capacity to house more than 400,000 original-equipment and premium-brand automotive parts, serving most vehicle makes and models on the road in Puerto Rico.
The warehouse will support the businesses of local independently owned auto parts stores throughout the western region, with parts deliveries for most customers taking place multiple times per day, six days a week.
“We are very proud to open our second Worldpac warehouse in Hatillo, bringing independent businesses in the western region greater access to original equipment and leading name brand auto parts,” said David Heine, Worldpac executive vice president of sales. “With two locations in Puerto Rico, we can now offer far greater inventory coverage across the island to better serve our customers. We’re also very pleased to employ members of the community at our new facility and we look forward to continued investment in Puerto Rico for years to come.”
Worldpac employs 10 team members at its new facility, with many living locally in Hatillo and surrounding communities. The company also supports independent auto parts stores through its warehouse in Bayamon, which opened in 2010.

The Latest in EV Brake Technology
Advances in electric vehicle systems are happening at record speed. Entire components are getting eliminated. What was once old is new again. But the NAPA experts are warning customers not to get ahead of themselves. Let’s slow down, stop spinning our wheels from all this momentum and start with the basics.
How do brakes work on an electric car? Almost all personal vehicles use disc brakes containing a pair of
link hidden, please login to view attached to a link hidden, please login to view, which squeezes the disc to generate friction and slow the wheel’s rotation. Electric cars utilize these standard mechanical brakes in cases of low speed and sudden emergency braking. In addition, an electric car brake system (found in hybrids, plug-in hybrids and full EVs) incorporates regenerative braking. Many consumers are familiar with brakes on electric cars because of the popularity in the past decade of the
link hidden, please login to view, which uses regenerative braking to deliver better fuel economy. Electric car brakes (regenerative brakes) capture the energy output (propulsion power) when a vehicle is slowing down, turning the electric motor into a generator for the battery pack. In more technical terms, the brake system in a hybrid or electric vehicle applies reverse current to the motor, which opens the charging circuit. The EV’s computer system determines the amount of ‘brake’ getting applied from the backward running motor, thus decreasing the speed until the vehicle comes to a stop. In a fully electric vehicle, this controlled braking extends the travel range by replenishing the battery system. As much as 90% of everyday braking is operated by this electric power switch. The hydraulic system (aggressively depressing the brake pedal to activate brake pads) is only necessary at speeds under 3 mph (when there isn’t enough energy momentum to transfer) or at high speeds with sudden emergency braking.
This ‘brake-through’ technology has created challenges when it comes to a seamless transition between regeneration and foundation braking. To create an unnoticeable transition with no rough jitters or jumping,

Similarly, the design of the Porsche Taycan also tackles the unequal distribution of braking power between the vehicle’s two axles. Two thirds of stopping power is provided by the front axle. This means the front brakes capture 60 to 80 percent of a slowing vehicle’s momentum compared to the rear battery generator.

For many decades, the advancements in brake systems have relied on improvements made to an isolated system. But with the expansion of consumer EVs, braking systems are now interconnected to the battery, powertrain and electronic conduction involved in deceleration. The way electric brake systems function has actually pushed car designers to reconsider an ‘outdated’ technology,
link hidden, please login to view. At one time, brake drums were the standard on personal vehicles until the invention of disc brake systems, which provided quicker stopping force. Because EVs require less engagement of mechanical brakes, especially on the rear axle, these newer vehicles run the risk of failing discs due to corrosion and rust from lack of use. This has generated renewed interest in rear axle drum brakes, which are sealed off from road and weather conditions. Learn more about why old-school drum brake technology is possibly the way of the future for compact commuter EVs in congested cities with
link hidden, please login to view. Because regenerative braking redirects the energy involved in stopping the vehicle, the lack of friction reduces the thermal load on your brakes and brake pads. This has led vehicle manufacturers to consider using thinner materials (like aluminum combined with cast iron) in brake pads, calipers and discs, which in turn makes EVs lighter weight and more energy efficient (longer runtime on a full battery). For a brake drum, this thinning can result in a 30% decrease in mass. However, in traditional brake systems, that large mass is required to absorb heat. So, the determining factor in using old tech for new EVs comes down to retaining enough resistance to heat-related brake fade.
Stop by NAPA Auto Care for EV Brake Maintenance
Now let’s talk about replacing EV brake pads and other components. Although mechanical brakes on a hybrid or EV are only relied on for quick, complete stopping, these components are still vital because regenerative systems are not designed for emergency braking or firmly holding a vehicle still. Relying on the motor to handle declaration does mean that brake pads for electric vehicles don’t wear out as quickly as full hydraulic brake systems on gasoline-powered combustion vehicles.
However, because they are used less (yet still exposed to moisture and grime), it is critical to ensure your EV brake pads are in good shape. This means routine maintenance and periodic cleaning every year versus wear-related replacement. For example, Tesla recommends cleaning and lubricating the brake calipers on a Model 3 once a year (or every 12,500 miles) for those who live in an area that uses road salt.
It is also true that fully electric cars do not require oil changes, exhaust inspections or spark plug replacement. But these prized vehicles still need brake system care, such as checking the brake fluid at least every two years. Dirty brake fluid needs a full brake system flush to prevent it from harming expensive auto parts. When in doubt, take your vehicle to

MAHLE Motorsport announced four new performance cast PowerPak piston sets for the 6-liter and 6.4-liter Ford Powerstroke.
Developed in direct response to consumer demand for diesel motorsports competition, the new 6-liter pistons are based on the 2004+ design, and the 6.4-liter pistons are based on the MaxxForce design that provides maximum strength and superior durability, according to the company.
“All four sets offer incredible versatility, allowing a daily driver to become a weekend warrior for drag, dyno or pulling competitions,” the company added.
The castings retain the OEM steel top ring insert for the longevity of the top ring groove and are engineered with fully radiused valve pockets to reduce stress and fatigue cracking. Also, a lower compression ratio (.5 to 1.5 points) allows more flexibility for high-output tuning.
They’re designed with performance bowls that reduce erosion issues caused by high pressure, long duration and advanced injection timing, and available with 0.100-inch-deep intake and exhaust valve pockets that work with many performance aftermarket camshafts.
The 6-liter PowerPak set is cast from MAHLE’s proprietary M124 alloy and the 6.4-liter Powerstroke set is cast from M142 alloy. Both are designed for a 4.134 stroke and 6.929 rod. The CR is calculated with 0.0008-inch piston protrusion above deck and 0.059-inch head-gasket thickness.
As with all PowerPak piston sets, the pistons are treated with MAHLE’s proprietary GRAFAL skirt coating for reduced drag and increased scuff resistance. Heavy-duty DLC-coated tool steel wrist pins, clips and a high-performance ring set rounds out the PowerPak.
“Diesel motorsports is all the rage from NHRDA, ODSS to Ultimate Callout Challenge,” MAHLE Motorsport Program Manager, Joe Maylish said. “We’re excited to announce that MAHLE Motorsport is coming in strong for 2023 with new diesel piston sets in time for this year’s race season. So, if you are a seasoned competitor needing an edge or just thinking about competing this year, our new Powerstroke kits are designed to give you the edge on the weekends and improve performance throughout the week.”

When I started my career as a technician, performance-related diagnostics were not that challenging when compared to today’s technology. Most symptoms could be isolated to a fuel or ignition-related problem with a simple road test. Diagnostic equipment was limited to some basic tools such as a timing light, rpm/dwell meter, compression gauge, vacuum gauge, volt/ohm meter, […]
