Hydraulic Brake System Bleeding (Pressure)
WARNING: This page is about a different car, the 2004 Suzuki Swift + and 2004 Chevrolet Aveo. However, it is still accessible from the selected car via links, so may be relevant.
- Disconnect the master cylinder electrical connector.
- Remove the master cylinder reservoir cap.
- Connect the bleeder with the adapter to the master cylinder reservoir.
- For vehicles with the anti-lock brake system (ABS), locate and remove the hydraulic modulator bleeder valves. Refer to Hydraulic Brake System Bleeding (Manual) or Hydraulic Brake System Bleeding (Pressure) in Antilock Brake System.
- Charge the bleeder ball to 140-172 kPa (20-25 psi).
- Connect the line to the adapter. Open the line valve.
- Raise and support the vehicle.
- Attach the bleeder hose to the bleeder valve. Submerge the opposite end of the hose in a clean container partially filled with brake fluid.
- Open the bleeder valve 1/2 to 3/4 of a turn and allow the fluid to flow until no air is seen in the fluid.
- Inspect the brake pedal for sponginess. Repeat the entire bleeding procedure to correct this condition.
NOTE:
Pressure bleeding equipment must be of the diaphragm type. It must have a rubber diaphragm between the air supply and the brake fluid to prevent air, moisture, oil, and other contaminants from entering the hydraulic system. Contamination could lead to deterioration of the braking components and loss of braking action.
NOTE:
Refer to Vehicle Lifting and Jacking Notice
in Cautions and Notices.
IMPORTANT:
The bleeding sequence is as follows: right rear, left front, left rear, and right front.
NOTE:
After the brake system bleeding procedure is complete, wrap a shop towel around the bleeder adapter and all hose connections before disconnecting. The brake reservoir may have residual pressure after the bleeding operation and failure to properly maintain the brake fluid may result in damage to components and painted surfaces.
