Coating on Rear Brake Caliper Pistons/FMVSS 135

A reduction of braking performance increases the risk of a crash.

 

Summary

Honda (American Honda Motor Co.) is recalling certain 2017-2019 Acura MDX, 2017-2018 Acura MDX Sport Hybrid, 2018-2019 Honda HR-V and Honda Odyssey, and 2016 Honda HR-V vehicles. The rear brake caliper pistons may have an insufficient coating, causing gas pockets to form, reducing brake performance. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 135, “Light Vehicle Brake Systems.”

 

Remedy

Owners will be notified, and Honda or Acura dealers will bleed the brakes, free of charge. The recall is expected to begin December 17, 2018. Owners may contact Honda customer service at 1-888-234-2138. Honda’s numbers for this recall are C31 and L30.

 

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Safety Recall: Soft or Low Brake Pedal

AFFECTED VEHICLES

Year	Model	Trim	VIN Range
2016, 2018-19	HR-V	ALL	Check the iN VIN status for eligibility.
2018-19	Odyssey	ALL	Check the iN VIN status for eligibility.

 

BACKGROUND

The brake pedal may have a soft feeling or travel to the floor with low effort because of air bubbles in the brake fluid. Air may be trapped in the system due to the temporary release of air bubbles from improperly plated rear brake caliper pistons. This may cause low braking performance or increased pedal stroke, increasing the risk of a crash.

 

CUSTOMER NOTIFICATION

Owners of affected vehicles will be sent a notification of this campaign.

Do an iN VIN status inquiry to make sure the vehicle is shown as eligible.

Some vehicles affected by this campaign may be in your new or used vehicle inventory.

Failure to repair a vehicle subject to a recall or campaign may subject your dealership to claims or lawsuits from the customer or anyone else harmed as a result of such failure. To see if a vehicle in inventory is affected by this safety recall, do a VIN status inquiry before selling it.

 

CORRECTIVE ACTION

Bleed the brake system.

REPAIR PROCEDURE

NORMAL BLEED

NOTICE

Do not spill brake fluid on the vehicle, it may damage the paint. If brake fluid does contact the paint, wash it off immediately with water.

NOTES

• Review the Service Precautions before doing repairs or service.
• Before beginning the bleeding procedure, remove the reservoir cap and strainer, and remove any dirt and debris then reinstall the strainer only.
• Use only new Honda DOT 3 Brake Fluid from an unopened container. Using a non-Honda brake fluid can cause corrosion and shorten the life of the system. Do not reuse the drained brake fluid.
• The brake fluid in the reservoir connected to the master cylinder must be at the MAX (upper) level mark at the start of the bleeding procedure and checked after bleeding each wheel. Add fluid as required.
• Unless indicated, the illustrations shown are examples only and may not match your vehicle.

Bleed the brake system in this order:

• Front Driver’s Side Brake Caliper
• Front Passenger’s Side Brake Caliper
• Rear Passenger’s Side Brake Caliper
• Rear Driver’s Side Brake Caliper

1. Raise the vehicle on a lift.
2. Attach a clear tube to the bleed screw.

 

3. Submerge the other end of the clear tube into a clear plastic catch bottle of brake fluid.
4. Have an assistant slowly pump the brake pedal several times then apply steady continuous pressure.
5. Loosen the bleed screw slowly to bleed the fluid into the plastic catch bottle. The brake pedal will travel toward the floor as the fluid is bled from the system.
6. When the brake pedal reaches the floor, have the assistant hold the pedal in that position, then tighten the bleed screw to the specified torque. The brake pedal can now be released.

NOTE

Inspect the brake lines and fittings for damage, leaks, deterioration, or twisting.

Component	Specified Torque Value
Front Brake Caliper Bleed Screw	10 N·m (7 lbf-ft)
Rear Brake Caliper Bleed Screw	11 N·m (8 lbf-ft)

 

7. Repeat steps 3 thru 6 until the brake fluid in the clear tube appears fresh and there are no air bubbles in the fluid.
8. Repeat this procedure for each caliper in the bleeding sequence.
9. Go to REAR CALIPER BLEED.

 

REAR CALIPER BLEED

NOTE

Do the following procedure only after doing the NORMAL BLEED procedure.

Bleed the rear brakes in this order:

• Passenger’s Side Rear Brake Caliper
• Driver’s Side Rear Brake Caliper

1. Remove the rear caliper body and remove the outer pad.
2. Place a small piece of cardboard in place of the outer pad and reinstall the brake caliper.

 

3. Slowly press the brake pedal until the caliper body contacts the cardboard.
4. Turn the ignition to ON.
5. Apply and release the parking brake.

NOTE

The air in the threaded portion between the spindle and the locknut is discharged by operating the parking brake.

 

6. Connect the HDS to the data link connector (DLC).

 

7. HR-V – Select ELECTRIC PARKING BRAKE from BRAKE SYSTEM menu with the HDS, then enter BRAKE PAD MAINTENANCE MODE from ADJUSTMENT, and follow the screen prompts.

• ODYSSEY– Select ADJUSTMENT from the ABS/VSA menu with the HDS, then select enter BRAKE PAD MAINTENANCE MODE from BRAKE PAD MAINTENANCE MODE, and follow the screen prompts. Make sure TRANSITION TO PAD EXCHANGE MODE HAS BEEN COMPLETED appears on the screen.

NOTE

The spindle returns to the initial position by entering the brake pad maintenance mode.

 

8. Turn the ignition to OFF.
9. Disconnect the negative cable from the 12 volt battery.
10. Press the brake pedal several times.
11. Disconnect the electric parking brake actuator connector, and remove the caliper body without disconnecting the brake hose from the caliper body.
12. Hold the caliper body so that the bleed screw is upright.
13. Direct any air trapped in the caliper by doing the following.

13.1 Shake the caliper side to side.

13.2 Strike the caliper several times using a plastic hammer.

 

14. Attach a clear tube to the bleed screw.

 

15. Install a commercially available brake caliper piston compressor tool between the caliper body and piston.
16. Loosen the bleed screw slowly and press in the piston with the brake caliper piston compressor tool.
    • If there are air bubbles in the fluid, tighten the bleed screw to the specified torque, install the rear brake caliper and repeat steps 2 thru 16.
    • If there are no air bubbles in the fluid, tighten the bleed screw to the specified torque, remove the cardboard and reinstall the outer pad and caliper.

Component	Specified Torque Value
Rear Brake Caliper Bleed Screw	11 N·m (8 lbf-ft)

 

17. Connect the electric parking brake actuator connector.
18. Press the brake pedal several times.
19. Reconnect the negative cable to the 12 volt battery.
20. Turn the ignition to ON.
21. HR-V – Select ELECTRIC PARKING BRAKE from BRAKE SYSTEM menu with the HDS, then enter BRAKE PAD MAINTENANCE MODE from ADJUSTMENT, and follow the screen prompts. Make sure THIS FUNCTION PROCEDURE IS FINISHED is displayed on the screen, then the press the enter button

• ODYSSEY– Select ADJUSTMENT from the ABS/VSA menu with the HDS, then select enter BRAKE PAD MAINTENANCE MODE from BRAKE PAD MAINTENANCE MODE, and follow the screen prompts. Make sure TRANSITION TO PAD EXCHANGE MODE HAS BEEN COMPLETED appears on the screen.

22. Apply and release the parking brake.
23. Turn the ignition to OFF.
