1. Introduction
This instruction manual provides essential information for the proper handling, installation, and maintenance of the Genuine Acura 45022-S0K-A11 Front Brake Pad Set. These brake pads are designed to meet the original equipment manufacturer (OEM) specifications for your Acura vehicle, ensuring optimal braking performance and safety. Please read this manual thoroughly before proceeding with any installation or maintenance.
2. Safety Information
Brake system work is critical for vehicle safety. Improper installation can lead to serious injury or death. It is highly recommended that installation be performed by a qualified automotive technician.
- Always wear appropriate personal protective equipment (PPE), including safety glasses, gloves, and closed-toe shoes.
- Ensure the vehicle is securely supported on jack stands on a level surface before beginning any work. Never rely solely on a jack.
- Allow the brake system to cool down completely before handling components.
- Do not use petroleum-based lubricants on brake components, as they can damage rubber parts.
- Dispose of old brake pads and brake fluid according to local environmental regulations.
- Consult your vehicle's service manual for specific torque specifications and procedures.

4. Installation Procedure
This section outlines the general steps for replacing front brake pads. Specific procedures may vary by vehicle model. Always refer to your vehicle's factory service manual for detailed instructions.
- Preparation: Park the vehicle on a level surface, engage the parking brake, and block the rear wheels. Loosen the front wheel lug nuts.
- Lift and Secure: Safely lift the front of the vehicle using a jack and support it securely with jack stands. Remove the front wheels.
- Caliper Removal: Locate the brake caliper. Remove the caliper guide pin bolts. Carefully slide the caliper off the rotor and support it to prevent strain on the brake hose. Do not let the caliper hang by the brake hose.
- Pad Removal: Remove the old brake pads from the caliper bracket. Note their orientation.
- Clean and Inspect: Clean the caliper bracket and guide pins. Inspect the brake rotor for wear, scoring, or warping. Replace rotors if necessary. Lubricate caliper guide pins with appropriate brake grease.
- Piston Retraction: Use a brake caliper piston compression tool to slowly and evenly push the caliper piston(s) back into the caliper bore. This creates space for the new, thicker pads. Open the brake fluid reservoir cap before retracting pistons.
- New Pad Installation: Install the new Acura brake pads into the caliper bracket, ensuring correct orientation (inner and outer pads). Apply a thin layer of brake lubricant to the backing plates of the pads where they contact the caliper and shims, if not pre-applied.
- Caliper Reinstallation: Carefully slide the caliper back over the new pads and rotor. Reinstall and torque the caliper guide pin bolts to the manufacturer's specifications.
- Final Steps: Reinstall the wheels and torque the lug nuts to specifications. Lower the vehicle. Pump the brake pedal several times until it feels firm before driving. Check the brake fluid level and top off if necessary.
5. Operating and Break-in Procedure
After installing new brake pads, a proper break-in (bedding-in) procedure is crucial for optimal performance and longevity. This process transfers a thin layer of friction material to the rotor surface, ensuring consistent braking and preventing noise.
- Drive the vehicle at a moderate speed (e.g., 30-40 mph).
- Apply the brakes moderately (not aggressively) to slow down to about 10 mph. Do not come to a complete stop.
- Repeat this process approximately 10-15 times, allowing a short cool-down period between each stop.
- Avoid hard braking or prolonged braking (e.g., long downhill descents) for the first 200-300 miles after installation.
During the break-in period, you may notice a slight burning smell or reduced braking effectiveness. This is normal. Braking performance will improve as the pads bed in.
6. Maintenance
Regular inspection of your brake pads is essential for safety and performance.
- Routine Inspection: Inspect brake pads for wear during tire rotations or at least every 10,000-15,000 miles.
- Minimum Thickness: Replace brake pads when the friction material wears down to the minimum recommended thickness (typically 2-3mm, or as indicated by your vehicle's wear indicators).
- Brake Fluid: Check brake fluid level regularly and ensure it is within the recommended range. Brake fluid should be flushed and replaced according to your vehicle manufacturer's schedule.
- Rotor Condition: Always inspect brake rotors for excessive wear, deep grooves, or cracks when replacing pads. Rotors should be resurfaced or replaced if they are below minimum thickness or show significant damage.
7. Troubleshooting
If you experience any issues after brake pad installation, consider the following common problems and solutions:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Squealing/Screeching Noise | Improper break-in, lack of lubrication on backing plates/shims, worn pads (wear indicator), foreign material. | Perform break-in procedure. Re-lubricate contact points. Inspect pads for wear. Clean brake components. |
| Grinding Noise | Severely worn pads (metal-on-metal contact), foreign object lodged in caliper. | Immediately inspect and replace worn pads. Remove foreign objects. Inspect rotors for damage. |
| Pulsating Brake Pedal | Warped brake rotors. | Inspect and replace or resurface brake rotors. |
| Soft/Spongy Pedal | Air in the brake lines, low brake fluid, faulty master cylinder. | Bleed the brake system. Check brake fluid level. Inspect for leaks. Consult a professional. |
If troubleshooting steps do not resolve the issue, or if you are unsure, consult a certified automotive technician.
