Front Brake Pads Inspection/Replacement



Frequent inhalation of brake pad dust, regardless of material composition, could be hazardous to your health.
  • Avoid breathing dust particles.
  • Never use an air hose or brush to clean brake assemblies. Use an appropriate vacuum cleaner.


Inspection


1.Raise the front of the vehicle, and make sure it is securely supported. Remove the front wheels.

2.Check the thickness of the inner pad (A) and outer pad (B). Do not include the thickness of the brake pad backing plate.

Brake pad thickness: 
 Standard: 10.5-11.5 mm (0.41-0.45 in.) 
Service limit: 1.6 mm (0.06 in.) 

Inner pad: 

Outer pad: 

3.If the brake pad thickness is less than the service limit, replace all the pads as a set.

Replacement (15 inch Brake Disc Type)


1.Remove the flange bolt (A).

NOTE: The pad springs are installed on the pads to prevent brake drag. Be careful when pivoting up the caliper body fully, or the spring could be flipped out of the position.

 

2.Pivot the caliper body slightly so the pads do not come out of position, and hold the pads on both sides firmly with your fingers. Remove the pad springs (A) from the pads.

 

3.Pivot up the caliper up out of the way and remove the pads (A).

 

4.Remove the pad shims (B).

5.Check the hose and pin boots for damage and deterioration.

6.Remove the pad retainers (A).

 

7.Clean the caliper thoroughly; remove any rust, and check for grooves and cracks.

8.Check the brake disc for damage and cracks.

9.Install the pad retainers.

10.Apply Dow Corning Molykote M77 grease to the back of the pads (B), and the other areas indicated by the arrows.
Wipe excess grease off the shim. Contaminated brake discs and pads reduce stopping ability. Keep grease off the discs and pads.

 

11.Install the brake pads and pad shim correctly. Install the pads with the wear indicators (C) on the inside.
If you are reusing the pads, always reinstall the brake pads in their original positions to prevent a momentary loss of braking efficiency.

12.Push in the piston (A) so the caliper will fit over the pads. Check the brake fluid level. The brake fluid may overflow if the reservoir is too full. Make sure the piston boot is in position to prevent damaging it when pivoting the caliper down.

 

13.Hold the pads on both sides firmly with your fingers, and install the new pad springs (A) on the pads.
Holding the pads, set the caliper over the pads by pivoting it down slowly.

NOTE: Insert the pad spring ends into the pad installation holes securely.

 

14.Pivot the caliper (A) down into position. Be careful not to damage the pin boots.

 

15.Install the flange bolt (B), and tighten it to the specified torque.

16.Press the brake pedal several times to make sure the brake works, then test-drive.

NOTE: Engagement of the brake 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.

17.After installation, check for leaks at hose and line joints or connections, and retighten if necessary.

Replacement (14 inch Brake Disc Type)


1.Remove the pin bolt (A).

NOTE: The pad springs are installed on the pads to prevent brake drag. Be careful when pivoting up the caliper body fully, or the spring could be flipped out of the position.

 

2.Pivot the caliper body slightly so the pads do not come out of position, and hold the pads on both sides firmly with your fingers. Remove the pad spring (A) from the pads.

 

3.Pivot up the caliper up out of the way and remove the pad (A).

 

4.Remove the pad shims (B).

5.Check the hose and pin boots for damage and deterioration.

6.Remove the pad retainers (A).

 

7.Clean the caliper thoroughly; remvoe any rust, and check for grooves and cracks.

8.Check the brake disc for damage and cracks.

9.Install the pad retainers.

10.Apply Dow Corning Molykote M77 grease to the back of the pads (B), and the other areas indicated by the arrows.

NOTE: Insert the pad spring ends into the pad installation holes securely.

 

14.Pivot the cliper (A) down into position. Be careful not to damage the pin boot (B), and check for the pin boot are not deformed or removed.

 

15.Install the pin bolt (C), and tighten it to the specified torque.

16.Press the brake pedal several times to make sure the brake works, then test-drive.
