Checking the power steering (Mitsubishi Lancer 3)

The operation of the power steering is checked if an exceptionally high pressure force on the brake pedal is required to achieve the required braking effect.

• Press the brake pedal and start the engine. The pedal should drop slightly.
• Press the brake pedal at least 5 times with the engine off, then start the engine with the brake pedal pressed. The brake pedal should noticeably drop down under your foot. In this case, the power steering is functioning normally. If not, check for leaks.
• Otherwise, remove the vacuum hose from the power steering, start the engine, and check for low pressure by placing your finger on the end of the vacuum hose.
• If there is no low pressure: check the vacuum hose for leaks and damage, otherwise replace. Tighten all clamps.
• Remove the low pressure hose from the vacuum pump and use your finger to check for low pressure where the hose is connected.
• If there is low pressure: measure the pressure, replace the power steering if necessary (work in a workshop).

Attention: In this case, it is necessary to replace the check valve in the vacuum tube, otherwise the power steering membrane may be damaged by the penetration of fuel vapors (if the check valve is defective).
