Answer

spomgy brake means air in the system, follow these steps to remove the air.

Caution: Do not move the vehicle until a firm brake pedal is obtained. Air in the brake system can cause loss of brakes with possible personal injury.

Caution: Use only SUPREME II or equivalent DOT 3 brake fluid from a clean, sealed container. Do not use fluid from an open container that may be contaminated with water. Improper or contaminated fluid will result in damage to components or loss of braking, with possible personal injury.

Caution: Do not overfill the brake fluid reservoir. Overfilling the brake fluid reservoir may cause the brake fluid to overflow onto the engine exhaust components during brake system service. The brake fluid is flammable and may cause a fire and personal injury if the brake fluid contacts the engine exhaust system components.

Notice: If any brake component is repaired or replaced such that air is allowed to enter the brake system, the entire bleeding procedure must be followed.

Notice: Avoid spilling brake fluid on any of the vehicle's painted surfaces, wiring, cables, or electric connectors. Brake fluid will damage the paint and the electrical connections. If any fluid is spilled on the vehicle, flush the area to lessen the damage.

Notice: Prior to bleeding the brakes, the front and rear displacement cylinder pistons must be returned to the topmost position, The preferred method uses a Scan Tool to perform the rehorning procedure. If a Scan Tool is not available, the second procedure may be used, but it is extremely important that the procedure be followed exactly as outlined.

A bleeding operation is necessary in order to remove air when air is introduced into the hydraulic brake system.
Bleed the hydraulic system at all four brakes if air has been introduced through a low fluid level or by disconnecting brake pipes at the master cylinder. If a brake hose or brake pipe is disconnected at one wheel, bleed only that one wheel caliper. If brake pipes or hoses are disconnected at any fitting located between the master cylinder and the brakes, then only bleed the brake system served by the disconnected pipe or hose.

With Scan Tool (Preferred Method)
Refer to Automated Bleed Procedure.

Without Scan Tool

Notice: This method can only be used if the amber ABS warning indicator is not illuminated and no DTCs are present.

Important: Do not place your foot on the brake pedal through this entire procedure unless specifically directed to do so.

1. Remove foot from the brake pedal.
2. Start the engine. Allow the engine to run for at least ten seconds while observing the amber ABS warning indicator.
3. If the amber ABS warning indicator turns on and stays on after ten seconds, stop the bleeding procedure. Use a Scan Tool in order to diagnose the ABS malfunction.
4. If the amber ABS warning indicator turns on for approximately three seconds, then turns off and stays off, turn the ignition off.
5. Repeat the previous four steps one more time.
6. Bleed the entire brake system.

Pressure Bleeding

• Tools Required
• J 29532 Diaphragm Type Brake Bleeder
• J 35589 Compact Brake Bleeder Adapter

Notice: 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, and other contaminants from entering the hydraulic system.

1. Inspect and fill the master cylinder reservoir to the proper level as necessary.
2. Assemble the components as shown.
3. Install the J 35589 to the master cylinder reservoir.
4. Connect the J 29532 to the J 35589.
5. Adjust the J 29532 to 35 - 70 kPa (5 - 10 psi) .
6. Wait approximately 30 seconds, then inspect the entire hydraulic brake system in order to ensure that there are no existing brake fluid leaks. Repair any brake fluid leaks.
7. Adjust the J 29532 to 205 - 240 kPa (30 - 35 psi) .

Important: Use a shop cloth in order to catch escaping brake fluid.

1. Slowly open the ABS modulator brake pipe fitting (1) starting from the first pipe on the left side in order to allow the brake fluid to flow. Notice: Refer to Fastener Notice in Service Precautions.
2. Close the ABS modulator brake pipe fitting when air bubbles are no longer detected in the brake fluid.

• Tighten the ABS modulator brake pipe fitting to 24 Nm (18 ft. lbs.) .

1. Repeat Steps 8 and 9 for the remaining ABS modulator brake pipe fittings.

1. Raise and suitably support the vehicle.
2. Install the clear plastic bleeder hose to the RIGHT REAR bleeder valve:

• For vehicles with rear drum brakes, install the clear plastic bleeder hose to the wheel cylinder bleeder valve.
• For vehicles with rear disc brakes, install the clear plastic bleeder hose to the brake caliper bleeder valve.
• 1. Submerge the opposite end of the clear plastic bleeder hose in a clean container partially filled with clean brake fluid.
  2. Slowly open the bleeder valve in order to allow the brake fluid to flow.
  3. Close the bleeder valve when air bubbles are no longer detected in the brake fluid.
  • For vehicles with rear drum brakes, tighten the wheel cylinder bleeder valve to 7 Nm (62 inch lbs.) .
  • For vehicles with rear disc brakes, tighten the wheel cylinder bleeder valve to 11 Nm (97 inch lbs.)
  1. Remove the clear plastic bleeder hose from the bleeder valve.

 

1. Install the clear plastic bleeder hose to the LEFT FRONT brake caliper bleeder valve.
2. Submerge the opposite end of the clear plastic bleeder hose in a clean container partially filled with clean brake fluid.
3. Slowly open the bleeder valve in order to allow the brake fluid to flow.
4. Close the bleeder valve when air bubbles are no longer detected in the brake fluid.

• Tighten the brake caliper bleeder valve to 13 Nm (115 inch lbs.) .

1. Remove the clear plastic bleeder hose from the bleeder valve.
