Can ABS Be Installed Aftermarket?
2 Answers
ABS can be installed aftermarket. The Anti-lock Braking System (ABS) functions and the items required for its installation are introduced as follows: Function of ABS: The Anti-lock Braking System (ABS) prevents wheel lock-up during braking by automatically adjusting brake force, ensuring the wheels maintain a rolling-sliding state (with a slip ratio around 20%) to maximize tire-ground adhesion. Items Required for ABS Installation: To install ABS, the following components must be replaced: four bearing housings, front-wheel left and right half-shafts, rear axle hubs, wiring harnesses, sensors, ABS hydraulic pump, ABS indicator light, ECU, brake lines, and brake fluid. If the vehicle has pre-installation mounting points, retrofitting ABS is feasible. Otherwise, structural reinforcement checks are necessary for the installation areas.
As a veteran driver with nearly 30 years of experience, I've considered installing ABS several times, but my experience tells me it's unreliable. The ABS system requires precise installation of sensors and control modules—it's not just about adding a few simple parts. You'd need to find a professional modification shop, and the cost is quite high, usually starting at several thousand yuan. If installed improperly, it might interfere with the original braking system, causing uneven braking or even failure, which is especially dangerous on slippery roads. Personally, I suggest that if your car doesn't have ABS, maintain a safe distance while driving and avoid sudden braking. Or, simply switch to a car with ABS—even a used one—as it’s more cost-effective and safer in the long run. ABS does prevent skidding, but forced retrofitting is less reliable than factory-integrated systems and brings additional maintenance hassles.
