Front Brake Pad Inspection and Replacement: Replacement

WARNING: This page is about a different car, the 2006 Acura MDX, 2005 Acura MDX, 2004 Acura MDX, and 2003 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
  1. Raise the front of the vehicle, and support it with safety stands in the proper locations (see LIFT AND SUPPORT POINTS ).
  2. Remove the front wheels.
  3. Remove the flange bolt (B) while holding the caliper pin A with a wrench being careful not to damage the pin boot, and pivot the caliper (C) up out of the way. Check the hose and pin boots for damage and deterioration.

  7. Clean the caliper thoroughly; remove any rust, and check for grooves and cracks.
  8. Check the brake disc for damage and cracks.
  9. Clean and install the pad retainers.
  10. Apply a thin coat of M-77 assembly paste (P/N 08798-9010) to the pad side of inner shim A, inner pad shim B, both sides of outer pad shim (C), the back of the brake pads (D), and the other areas indicated by the arrows. Wipe excess assembly paste off the shims and brake pads. Contaminated brake discs or brake pads reduce stopping ability. Keep assembly paste off the brake discs and brake pad materials.

  11. Install the brake pads and pad shims correctly.

    Install the brake pad with the wear indicator (E) on the upper inside.

    If you are reusing the brake pads, always reinstall the brake pads in their original positions to prevent a momentary loss of braking efficiency.

  12. Install the pad springs (A) while holding the brake pads.

  14. Press in the piston with the brake caliper piston compressor so the caliper will fit over the brake pads. Make sure the piston boot is in position to prevent damaging it when pivoting the caliper down.
    NOTE: Be careful when pressing in the piston, the brake fluid might overflow from the master cylinder's reservoir.
  15. Remove the brake caliper piston compressor.
  16. Pivot the caliper down into position. Install the flange bolt (B), and torque it to the specified torque while holding the caliper pin A with a wrench, being careful not to damage the pin boot.

  17. Press the brake pedal several times to make sure the brakes work.
    NOTE: Engagement of the brakes may require a greater pedal stroke immediately after the brake pads have been replaced as a set. Several applications of the brake pedal will restore the normal pedal stroke.
  18. After installation, check for leaks at hose and line joints or connections, and retighten if necessary. Test-drive the vehicle, then check for leaks.
