An ABS (or Anti-Lock Braking System), a technology that has saved countless lives by preventing your car’s wheels from locking up and skidding—something that’s all too easy when you stubbornly slam your ‘pedal to the metal’ to avoid a crash, is likely present in your car if it’s from the past 20 years. The key component of modern ABS is the ‘ABS pump’, a subtle piece of technology that modulates hydraulic pressure to achieve this effect. (We’ll dive into the details next time, promising something tech-y after all the language-y posts!) However, like all strong mechanical parts, the ABS pump will slowly wear down and, if neglected, can lead to a failure in your braking system and vehicle safety.
You will be pleased to hear that buying a new ABS pump puts quite a dent in your wallet as well as the planet, and ABS pump refurbishment is the ideal solution. This guide will set an ABS refurbishment in motion and describe the steps for its performance and adoption. Anyone interested in the field will learn a lot of useful information.
How does an ABS pump work?
Imagine slamming your foot on the brakes during an emergency manoeuvre on an icy or wet road, inducing a general lock-up of the wheels. Not only does this massive increase in friction force create a huge jerk, but it also destroys steering control and dramatically extends stopping distances—a situation that an ABS pump counteracts.
The ABS pump itself is located between the wheel speed sensors and a controller unit. Those two components, in conjunction with the ABS pump and a system of hydraulic lines, work together to prevent lockups of the wheels. Here’s a simplified explanation of how it all fits together in the ABS braking process:
-
Detection: The wheel speed sensor at each wheel continuously monitors the rotational speed of the wheels during strong braking, when we feel the engine brake activating.
-
Locking Detection: If the ABS controller senses a rapid decrease in wheel speed (indicating an impending lockup), it sends a signal to the ABS pump.
-
Pressure Modulation by the ABS Pump: The ABS pump reduces hydraulic pressure on the affected wheel very rapidly, allowing it to rotate faster.
-
Recovers Traction: After rotating back to speed, the tyre regains contact with the road. Because the tire hasn’t torn off the rim, it maintains its grip on the road. The tyre’s restoration of traction allows the vehicle to maintain control over the steering wheel.
-
Re-application of Pressure: Having returned the wheel from its locked-up state, the ABS controller sends another command that alters the ABS pump to re-apply pressure, moving the wheel back towards the lock-up boundary.
-
Continuous Monitoring Adjustment: The rapid application, release, and re-application of pressure continues for as long as heavy brake pedal pressure is applied. The wheels never stop turning completely, yet they are constantly on the verge of locking up.
In an ABS pump refurbishment, the goal is to replace a no-good pump with a good one.
Benefits of ABS Pump Refurbishment
Replacing a malfunctioning ABS pump with a brand new assembly is different from refurbishment. We summarize the information below, preserving all citations and quotes.
Refurbishment offers several benefits over replacing a malfunctioning ABS pump with a new unit:
Economic: Purchasing and assembling a brand new ABS pump is more expensive than rebuilding an existing pump. The equipment is also more versatile. We can rebuild almost all kinds of automobile ABS pumps. So if the pump in your car fails, don’t throw it away. It might be better to send it to us for repair. Get a free quotation from [email protected]. If we can’t fix it, we’ll return it to you. 50%~70% savings.
Ecologically Sustainable: Let’s say a vehicle manufacturer creates a brand new ABS pump, and a professional mechanic then disposes of it in a landfill. When you have your brakes serviced by refurbishing your ABS pump, you are creating a second life for an item that very likely already exists. From an ecological standpoint, getting your brakes serviced by refurbishing your ABS pump is clearly more sustainable.
Maintains Original Performance: A rebuilt ABS pump will return your vehicle’s drive train to near-original performance, keeping the brakes working as they should.
ABS pumps for the majority of popular makes and models are readily available, saving you the time it would take to have your original ABS pump refurbished.
Quality Control: Reputable reconditioning houses rebuild pumps to OEM (Original Equipment Manufacturer) standards.
The ABS Pump Refurbishment Process: A Step-by-Step Guide
The ABS pump refurbishment process typically involves the following steps:
-
A qualified technician will start with a wide inspection. He will disassemble the ABS pump and clean all the parts, checking them carefully for damage, wear, or corrosion. First, we inspect the pump housing, motor, valves, and inner seals for any damage that may require replacement.
-
We replace worn or broken components with new, high-quality parts. We often replace the motor with a new one, in addition to seals and bearings.
-
Cleaning and calibration: To eliminate any potential contaminants, we clean all of the pieces. We would need to calibrate some parts, like the pressure-regulating valve, to ensure correct operation.
-
Testing and Quality Control: After the restoration and return of the ABS pump to functional condition, testing is necessary to verify that the functionality meets the original specification.
Conclusion
ABS pump refurbishment is a cost-effective solution for vehicles with outdated ABS systems. The pump, located between wheel speed sensors and a controller unit, works to prevent wheel lock-ups during emergency maneuvers. It reduces hydraulic pressure on affected wheels, recovers traction, re-apply pressure, and continues monitoring adjustment. Refurbishment offers several benefits over replacing a malfunctioning ABS pump: it is more economical, environmentally sustainable, maintains original performance, and is more versatile. The process involves a wide inspection, replacement of worn or broken components, cleaning and calibration, and testing and quality control. Reputable reconditioning houses can rebuild pumps to OEM standards, saving time and money. The process typically involves a wide inspection, replacement of worn or broken components, cleaning and calibration, and testing to ensure the pump meets original specifications.
