ABS/ESC False Activation Diagnostics
False activation incidents involve the ABS modulator taking over braking or intervening to restore vehicle stability.
Understanding ABS Modulator Problems
Mechanical issues with the ABS modulator or hydraulic control units (HCU), are rare, but they can happen. With more vehicles on the roads having older ABS systems that have not seen proper brake fluid maintenance, mechanical issues are becoming more common.
Wheel Bearing Technology: Don’t Become Complacent
Wheel bearings are changing because the vehicles they are attached to and the brake rotors located on the other side are evolving. This has changed the designs and specifications for most bearings.
Tech Tip: Intensive Wheel Hub Cleaning Process
Recently, we had a Jeep Grand Cherokee in our shop for a brake job. Upon removing the rotor, we found one of the rustiest wheel hubs we have ever seen.
Composite Rotors: Can They Be Serviced?
When you hear the words “composite rotor,” you might think of a racecar brake rotor with Allen head bolts holding the hat to the outer ring.
Ex’Splining’ New Wheel Bearing Designs
From an engineer’s perspective, wheel bearing design and selection can be a balancing act between durability, cost and fuel economy.
New Wheel Bearing Technology Will Change Your Replacement & Diagnostic Approach
Two technologies are now being used on new vehicles and in aftermarket replacement hub units that allow engineers to put better bearings in smaller packages. These technologies will change the way you replace and diagnose wheel bearings.
Friction And Formulations
Friction is the force resisting the relative motion of elements sliding against each other. In the case of cars and trucks, it is the brake pads pushing against a rotor that changes kinetic energy into heat.
Mercedes-Benz Floating Composite Rotors
When you hear the words “floating rotor,” you might think of a racecar brake rotor with Allen head bolts holding the hat to the outer ring. But, more economical and robust “semi-floating” rotors have made it onto Audi, BMW and Mercedes-Benz daily drivers.
Proper Rotor Service Prevents Comebacks
Uneven rotor wear often produces variations in thickness that can be felt as pedal pulsations when the brakes are applied.
