Anti-Lock Braking system is one of the most crucial component of any car safety. Commonly referred to as ABS, it allows a driver to apply brake pressure without skidding or locking up a wheel. An anti-lock braking system will work by sensing when a tire is about to stop rotating due to skidding. The ABS then electronically pulses the brakes in order to free up the wheel and prevent it from locking up again. It can stop a vehicle from going out of control which used to happen with the older form of brakes.
Japanese brands of Toyota and Lexus are two of the world’s most well-known automobile brands. In the year 2021, Toyota ended up as the most sold vehicles in the United States despite the fact that USA itself has some of the world leading vehicle brands like Ford, Chevrolet and GMC. Lexus is a luxury extension of Toyota and thus remains a favorite for those who look for luxury and power. Some of the known Lexus models include LX, GX, RX, NX, LS, GS, IS and ES. On the other hand, Corolla, Camry, Prius, Avalon, Land Cruiser, 4Runner, and RAV4 are some of the famous Toyota models. Despite being different brands producing different models, they do have some parts in common like engines, suspension and ABS just to mention a few. Toyota Land Cruiser 1998-2007 and Lexus LX470 1998-2007 have same engines and ABS systems. Similarly, Toyota 4Runner 2003-2004 and Lexus GX470 2003-2004 have same ABS pumps.
Wear and Tear in Anti-Lock Braking System
The ABS braking system is a way of putting the brakes on your car. It does this by using a system using hydraulic fluid to push pads out from behind drums, which in turn creates friction. The friction then causes a slowing or stoppage of the rotation of the drum or wheels. As a result, you have a lot less chance of losing control and going off-road. A common misconception about brakes is that your car automatically slows down when you step on the brake pedal. This is not always true because all cars can vary in size and dimensions so it's important to know how the brakes work for the specific make and model before deciding if they are good enough for your needs. The ABS Assembly can begin to fail when you brake too hard or too soft. The hydraulic fluid that powers the assembly may not be calibrated for this type of driving and get stuck in a position where it no longer rotates as it should. Over time, the brakes will wear down and eventually need repairs such as adding anti-freeze and replacing the brakes and drums. The best way to determine if your ABS Assembly is having problems is by reading the owner's manual. Doing this ensures you know how to operate your car correctly and can avoid serious damage or injury as a result of using it incorrectly.
The ABS system has a series of sensors and a hydraulic pump connected to it. The sensors detect the speed and rate at which the wheels are turning while the brake pedal is being depressed. The pump works with a hose connected to it to provide pressure for the brakes when needed. If you’ve noticed a squealing noise when braking, or if your vehicle hesitates to stop after pressing the brake pedal, your ABS assembly may need replacement.
Replacing your ABS Pump
When it comes to replacing your bad Anti-Lock Brake ABS pump, there are two options; either to go for the brand new one or get one which is removed from a salvage car. While the new one could be very expensive, the pre-owned ABS pump could prove very economical and as efficient as the new one at the same time. In the United States, every year hundreds of thousands of vehicles are auctioned when the repair cost surpasses the total value of the car or when a car becomes unsafe for driving due to some accident. Most of the parts of such cars are in good working condition and could be removed to be used in other similar cars.
When you are able to decide that you have to go for a pre-owned ABS Master Cylinder Assembly, the next natural question comes is to find out which ABS pump is being used in your vehicle. While some cars have same ABS pumps for a particular year, others have varying part numbers which may make it a little difficult to find the exact part number. Nevertheless, the online market has made it all easy to find the exact part number. A credible online seller with good expertise can be picked without much worry to get the needed part.
Knowing Part Number of your ABS Pump
There is yet another challenge and that is to know what part number your ABS pump is. Though all ABS master cylinder assemblies come with a part number printed on it but years of wear and tear and washing may lead to fading away of the part number or simply removal of the tag which carries the number. This becomes tricky when varying ABS pumps are being used in a similar car model and year. In such a situation, only a good mechanic would be able to suggest the right part number.
A good example is the Toyota Land Cruiser ABS Master Cylinder Assembly for the year 1998 till 2007. Now there are at least three different ABS pumps which may fit a 2002 Toyota Land Cruiser. The first one comes with a triangle-shaped connecting sensor while the second one has an oval-shaped sensor. The third one simply does not have a sensor and is more prevalent in 1998-1999 models. Same is the case for Lexus LX470 Anti-Lock Brake ABS Master Cylinder Assembly. Both the vehicles have same ABS pumps used in those years. Again, the above three ABS pumps come with different part numbers. Luckily, the change in part numbers do not bring any change in the ABS pumps and thus could be used interchangeable. For example, Lexus LX470 2001 ABS pump with a triangle-shaped sensor may carry 47210-60062 or 47210-60063 part numbers. Both are same and can be used interchangeably without hesitation in Toyota Land Cruiser or Lexus LX470. Similarly, the sensor-less ABS for Toyota Land Cruiser and Lexus LX470 1998 may have the part numbers ending in 10, 12 or 13. On the contrary, Toyota 4Runner 2003-2004 and Lexus GX470 2003-2004 have same ABS pumps without any physical difference. They do come in three different part numbers but they could safely be used interchangeably.
Knowing Part Number of ABS Pumps in Hybrid Cars
As compared to the gasoline-run cars, ABS pumps in hybrid vehicles happen to be more problematic and may need replacement after years of use. However, finding the part numbers for ABS pumps in hybrid vehicles like Toyota Camry and Toyota Prius or Lexus GS300H may not be that tricky. The reason is that every individual car has a particular ABS number and the tag carrying the number is long lasting. It neither withers away with wear and tear nor can easily be removed making it convenient to have a look at the ABS pump and read the part number.
