Manual Bleeding

Print

  1. Remove the booster vacuum reserve by applying the brakes several times with the ignition OFF .
  2.  
  3. Fill the master cylinder reservoir with brake fluid and keep the reservoir at least one-half full of fluid during the bleeding operation.
  4.  
  5. The master cylinder should be bled before the calipers are bled. If the master cylinder is known or suspected to have air in the bore, bleed as follows:

    Disconnect the forward brake pipe connection at the master cylinder.
     
    Fill the master cylinder with brake fluid until it begins to flow from the forward pipe connector port.
     
    Connect the forward brake pipe to the master cylinder and tighten.
     
    Slowly depress the brake pedal and hold.
     
    Loosen the forward brake pipe connection at the master cylinder to purge air from the cylinder.
     
    Tighten the connection to 24 ft. lbs. (35 Nm).
     
    Slowly release the brake pedal.
     
    Wait 15 seconds and repeat steps until all air is removed from the bore.
     
    Bleed the master cylinder at the rear (cowl end) connection after all the air has been removed at the forward connection.
     
    Check for firm pedal feel and proper brake pedal travel. If the wheel cylinders and calipers do not contain air bleeding may not be necessary.
     

  6.  
  7. Bleed the individual calipers after all air is removed from the master cylinder using the following procedure at each caliper in sequence:
    NOTE
    Do not pump the brake pedal rapidly; pumping pushes the master cylinder secondary piston down the bore which causes difficulty bleeding.



    Attach a transparent tube over the valve and allow tube to hang submerged in a transparent contained filled with brake fluid.
     
    Slowly depress the brake pedal and hold.
     
    Loosen the bleeder valve to purge the air from the cylinder.
     
    Tighten the bleeder screw to 10 ft. lbs. (13 Nm).
     
    Slowly release the pedal.
     
    Wait 15 seconds.
     
    Repeat the sequence until all air is removed from the caliper.
     

  8.  
  9. Bleed brakes in the following sequence:

    Bleed the left front caliper.
     
    Bleed the right front caliper.
     
    Bleed the left rear caliper.
     
    Bleed the right rear caliper.
     

  10.  
  11. Check the brake pedal for sponginess.
  12.  
  13. Repeat the entire bleeding procedure if a low brake pedal or pedal sponginess is encountered.
  14.  


WARNING
 Brake fluid is extremely damaging to paint. If fluid should accidentally touch a painted surface, immediately wipe fluid from paint and clean the painted surface.


NOTE
If it is determined that air was induced into the system upstream of the ABS modulator prior to servicing, the ABS Automated Bleed Procedure must be performed.
