What is the first step to take before replacing a hydraulic brake hose on an ABS equipped vehicle?

The first step to take before replacing a hydraulic brake hose on an ABS-equipped vehicle is to relieve brake system pressure according to manufacturer procedures. This action is crucial because it ensures that there is no residual pressure in the brake lines, which can lead to brake fluid spraying out when the hose is disconnected. Releasing the pressure helps to maintain safety during the repair process and prevents potential injury to the technician.

Additionally, following manufacturer procedures is vital, as different vehicles may have specific guidelines for relieving system pressure, ensuring that the process is carried out safely and effectively. This step is essential for the integrity of the braking system and for preventing damage to components during the hose replacement. Once the pressure is relieved, subsequent steps like disconnecting the battery, removing the wheel, or inspecting fluid levels can be undertaken with a greater assurance of safety.
