CX-7 AWD L4-2.3L Turbo (2008)
During rotor replacement, ensure the hub is free from any foreign substances that may prevent the rotor from fitting flush against the hub. A rotor that
does not fit flush against the hub may experience a reoccurrence of brake judder.
BRAKE DRAGGING
This procedure will assist in finding the cause and appropriate repair for the brake dragging.
Inspection:
1. Safely raise the vehicle on a hoist.
2. Determine which wheel the brake dragging is occurring from.
3. Remove the wheel, then rotate the brake rotor by hand to confirm the brake dragging.
4. Loosen, but do not remove the two (2) bolts securing the caliper to the bracket.
5. With the brake pads still installed, remove the bottom bolt and rotate the caliper upwards.
6. Rotate the rotor by hand again and confirm if brake dragging is still present.
- If the brake dragging is still present, check for the following:
^
Brake pads seized in the mounting support/hardware.
^
Contact between the brake rotor and other components.
^
A seized wheel bearing.
^
Brake booster push rod out of adjustment.
- If the brake dragging is not present, check for the following:
^
A seized or slow to return caliper piston.
^
A seized caliper slide pin(s).
^
Lateral runout of the rotor exceeds specification.
Inspection Results & Repair:
^ If seized brake pads are found, clean the mounting support/hardware and brake pads before reinstalling.
^ If contact between the brake rotor and other components is found, repair as necessary.
^ If a seized wheel bearing is found, replace it according to MS3 online service information or the appropriate Workshop Manual.
^ If the brake booster push rod is out of adjustment, readjust according to MS3 online service information or the appropriate Workshop Manual.
^ If a problem is found with the caliper piston return, check for the possibility of water entry due to caliper piston boot breakage or poor sealing, etc.
Review the vehicle's maintenance and repair history before deciding on whether to rebuild or replace the caliper.
^ If seized caliper slide pin(s) are found, remove the pins. Clean and lubricate the pins, then reinstall.
^ If a brake rotor runout problem is found, machine the rotors using an on-car lathe and refinish the brake pads using sandpaper (grit #80).
NOTE:
DO NOT use an off-car lathe for warranty repair
