Multiple Choice

When flushing or bleeding a vehicle equipped with ABS, you should:

When bleeding a vehicle with ABS, the procedure must follow the manufacturer’s specific instructions because the ABS pump and modulator can trap air and require a particular sequence or tool-assisted cycling to purge it properly. The service manual will specify whether you need to power the ABS, perform a forced bleed with a scan tool, or bleed in a particular order to ensure air isn’t left in the modulator or lines. Gravity bleeding, disabling the ABS, or using high‑pressure air can fail to remove air from the ABS circuit, damage components, or create unsafe braking conditions. Following the manual ensures you purge air correctly and restore proper pedal feel and braking performance.
