Innova SDS50 SDS-Tech: ABS Bleeding

Purpose

To guide you on how to perform the ABS Bleeding function while using the Innova SDS50 SDS-Tech Tablet Scan Tool.

Introduction

Nowadays, the Anti-lock Braking System (ABS) has become a standard safety feature found in the majority of modern vehicles. Its primary function is to handle the braking process, allowing you to prioritize the safe control of the vehicle during emergency situations. The ABS is specifically designed to prevent the wheels from locking up when sudden braking occurs.

Whenever maintenance or repairs are conducted on the ABS, such as the replacement of calipers, master cylinders, wheel pistons, hoses, or lines, there is a possibility for air to enter the brake system circuit. The presence of air in the system results in a delayed response from your brakes. This happens because the air bubble within the brake circuit is compressed before the brake fluid can be compressed. Consequently, you will experience a spongy and soft sensation when pressing the brake pedal.
