The anti-lock braking system (ABS) computer, or HCU, is a node on a high-speed vehicle bus. ESC systems add software and sensors like yaw, steering angle and even throttle control to keep the vehicle under control. This will release or bleed off the hydraulic pressure that is holding the wheel. The wheel might start to turn.
Transmission Fluid Hydraulics and Shifting To understand why using the correct transmission fluid is necessary, you first have to know how the transmission fluid flows inside an automatic transmission. This is basic hydraulics. Foamy fluid can change shift characteristics and the hydraulic operation of the transmission.

Electric power steering (EPS) has become a game-changer in the world of electric vehicles (EVs). Unlike traditional hydraulic power steering systems, EPS utilizes electric motors and electronic control units to assist the driver in steering the vehicle. This video is sponsored by BendPak.
As vehicle engineering evolves and track-capable road cars become more common, the quality and performance of brake fluids have taken center stage. Brake fluid may seem simple, but it plays a complex and vital role in vehicle control. Additionally, luxury and performance vehicles now come from the factory with DOT 4 or 5.1
Most internal combustion vehicles could not go this far. Brake Pad Wear: Regenerative vs. Hydraulic Braking When you hit the brake pedal on most internal combustion vehicles, hydraulic pressure moves from the master cylinder to the calipers. The pads generate friction and heat to stop the vehicle.
Have you ever inspected a customer’s vehicle, and found what looks like fluid coming from one of the suspension bushings? That bushing could be hydraulic, and it’s a good service opportunity for you and your shop. What’s so different about hydraulic bushings? Hydraulic bushings fill those empty voids with a fluid.

This is basic hydraulics. Foamy fluid can change shift characteristics and the hydraulic operation of the transmission.
However, when it comes to EV brake system service , many of the same repair procedures from internal combustion vehicles (ICE) still apply. From the basic principles of friction braking to advanced safety features like ABS, both vehicle types rely on similar technologies and design fundamentals.
However, for the safest brake job with the best performance, its always best to use parts from the same manufacturer, like ADVICS, where our brake pads, brake rotors, hydraulics, calipers and brake fluid are designed and manufactured to work together. There are several benefits to both your shop and customer if you follow this advice.
The vehicle will also pull to the left. Gauging Your Work When diagnosing a pull due to uneven hydraulic pressure, a pair of brake pressure gauges can come in handy for comparing pressures side to side. They tee into the brake lines and can be used to directly measure hydraulic pressure.
In this episode of Inside the Brands, we take a closer look at Chryslers Electro-Hydraulic Power Steering (EHPS) system on models like the Challenger, Charger, 300, and Grand Cherokee from 2011-2015.

Worn Shocks and Struts The problem: Over time, shocks and struts wear out, leading to excessive bouncing, nose-diving during braking, or poor vehicle handling. Broken or Sagging Springs The problem: A vehicle that sags on one side or feels unstable in turns may have a sagging or broken coil spring.
For example, our Auto Mechanic Training program offers modules on specialized topics like hydraulic brake systems, steering systems, and wheel alignment. Knowledge in these areas is increasingly necessary as vehicles become more sophisticated. Onboard computers and environmentally friendly systems are now standard in many new models.
You can now see that his law has everything to do with the theory of hydraulics and certainly modern-day hydraulic braking systems used predominantly across vehicles today. Fundamentally, without a contained path for fluid to travel, we would have no hydraulics. Hard lines are used to run the length of the vehicle.
From minor fluid seepage to hydraulic bushing failure, learn the steps to identify wear before it turns into a costly repair. Following a thorough, systematic inspection approach helps maintain vehicle performance, safety and customer trust. Watch the video above for more. This video is sponsored by bproauto.
As the automotive industry evolves, vehicles are no longer simple machines but complex interconnected systems that blend hardware and software. In the ultra-connected landscape, preventive maintenance also includes monitoring the vehicle’s software health.

Whether you’re servicing a pickup truck with active dampeners and air ride or a luxury sedan with hydraulic dampeners, these systems have faced their fair share of criticism from technicians over the years. Active suspension systems have come a long way since they were first introduced for performance vehicles.
Power steering is now offered in a few different ways; hydraulic, electrical, and more recently, drive-by-wire. On nearly all vehicles, there is a steering column connecting the steering wheel to the wheels themselves using a system called a rack and pinion. Hydraulic steering is not without flaws though. What is Power Steering?
Many vehicles were no longer equipped with limited slip and Torsen differentials at the axles. The brake hydraulic control module on these vehicles has at least 12 valves. If the vehicle is in snow or mud, it can control the traction with the brakes so the differential acts like it is locked. So, what happened?
Parts that wear out and may have to be replaced include the pressure plate, friction disc, release bearing, pilot bearing or bushing (if used) and components in the clutch linkage (the cable, cable adjuster, or in a hydraulic linkage, the master or slave cylinder). In cable systems, the preload is provided by the ratchet and pawl.
These professionals assess vehicle damage and provide accurate repair cost estimates. While auto body estimation training generally focuses on passenger vehicles, another specialized field within the industry is Heavy-duty Estimation. Heavy-duty estimation deals with large vehicle systems after auto body estimating training.
Like internal combustion vehicles, many service procedures are identical for EVs and hybrids. With these vehicles, the major aggravation for shops is brake noise and uneven brake pad wear. With these vehicles, the major aggravation for shops is brake noise and uneven brake pad wear. What should you worry about?
An under-the-vehicle inspection typically involves inspecting the brakes, suspension and tires. But, with modern vehicles, there is a lot more to look at. But, many late-model vehicles use active aero devices to cheat the wind and improve efficiency. Today, a fender liner can protect the wire harness, modules and the engine.
Brake systems are one of the most critical safety features in any vehicle, and as an aspiring technician, youll need to be confident in your ability to service them correctly. Most modern passenger vehicles use hydraulic disc brakes in the front and either disc or drum brakes in the rear.
However, for the safest brake job with the best performance, it’s always best to use parts from the same manufacturer, like ADVICS, where our brake pads, brake rotors, hydraulics, calipers and brake fluid are designed and manufactured to work together. There are several benefits to both your shop and customer if you follow this advice.
The torque-vectoring differentials can control the amount of power going to each wheel connected to the axle using hydraulics or electric solenoids. Some high-horsepower front-wheel-drive vehicles have a basic torque-vectoring differential (such as the Ford Fiesta RS) to control torque steer.
The switch might have gotten complicated if the vehicle had cruise control. If you look under the dash on most vehicles, you will see several different styles of switches. Also, hybrids and battery electric vehicles use the input from a brake pedal sensor for regenerative braking. seconds or more. G or more for 1 second or more.
Today, we sneak a peek at two notable military vehicles. On the one hand, we have the Buffalo Mine-Protected Clearance Vehicle (MPCV); on the other, we have the Buffel Armored Personnel Carrier (APC). In and out of the military, the literature on cars is peppered with animal-inspired vehicle names. Lets take a look shall we?
In the late 1980s, many cars now had wide front tires and it was difficult to route hydraulic lines from the engine bay to the front of the vehicle and the rack. Many of the first systems were electro-hydraulic with a electric motor powering a hydraulic pump. The ABS module can also apply the brakes to steer the vehicle.
If a customer comes to you saying they saw fluid leaking from a suspension bushing, it probably means they may have hydraulic bushings on their vehicle. In this video, let’s discuss what hydraulic bushings are and some tips for properly servicing them.

Many graduates of diesel mechanic courses enter the workforce as general diesel mechanics, while others specialize in specific vehicles, equipment, or systems. This specialization requires expertise in diesel engines, hydraulics, and complex electrical systems. Here are four in-demand specializations to consider.
All of these vehicles have something in common: they can be tough to handle, especially when the weathers bad or the roads are rough. Plus, those larger aftermarket tires can add over 25 pounds of unsprung weight to each corner of the vehicle. Most owners of these vehicles dont know that you can help them out.
Going this far would be unimaginable for most internal combustion powered vehicles. When you hit the brake pedal on most internal combustion vehicles, hydraulic pressure is generated by the master cylinder and sent to the calipers. The hydraulic pressure causes the calipers to clamp down on the brake pads and rotor.
