I have a nice hard pedal to be expected no boost

Good morning,

You need a scan tool that can read the ABS system. The ABS has air in the system and must be purged. The scan tool will perform an automated bleeding procedure for the unit.

You have air in the system. There is no issue with the booster.

PROCEDURE
1. Raise the vehicle to gain access to the system bleed screws. Install clear tubing on the bleed screws so that air bubbles in the fluid can be seen.

NOTE: Never pump the brake pedal as fluid cavitation may occur.

2. Begin by bleeding the system at the right rear wheel, then the left rear, right front and left front.
3. Open one bleed screw at a time 1/2 to 1 full turn.
4. Slowly depress the brake pedal until it reaches its full travel and hold until the bleed screw has been tightened. Release the brake pedal and wait 10-15 seconds for the master cylinder to return to the home position.

NOTE: Repeat steps 1 through 4 until approximately 1 pint of brake fluid has been bled from each wheel. Clean brake fluid should be present at each of the wheel bleed screws. Check the master cylinder fluid level every 4 to 6 strokes of the brake pedal to avoid running the system dry.

5. After bleeding all four wheels, use a Tech 1 Scan tool to run 4 functional tests while applying the brake pedal firmly.
6. Rebleed all four wheels using steps 1 through 4 to remove the remaining air from the brake system.
7. Evaluate the brake pedal feel before attempting to drive the vehicle and rebleed as many times as necessary to obtain appropriate pedal feel.

You are welcome.

Always glad to help.
