Bendix D865 CQ Brake Pad Set User Manual
Model: D865
1. Introduction
The Bendix D865 CQ Brake Pad Set is engineered to provide superior braking performance with reduced noise and dust. These ceramic quiet pads feature 100% attached shims and chamfers, designed to maximize noise reduction and ensure a smooth, confident braking experience. This manual outlines the proper procedures for installation, maintenance, and troubleshooting to ensure optimal performance and safety.
2. Safety Information
Always prioritize safety when working on vehicle braking systems. Improper installation or maintenance can lead to serious injury or vehicle damage. Consult a qualified mechanic if you are unsure about any procedure.
- Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
- Ensure the vehicle is securely supported on jack stands before beginning any work. Never rely solely on a jack.
- Allow brake components to cool down before handling, as they can become extremely hot during operation.
- Keep brake fluid away from painted surfaces, as it can damage paint.
- Dispose of old brake pads and fluids according to local environmental regulations.
- After installation, pump the brake pedal several times to ensure proper pad seating and brake fluid pressure before driving.
3. Setup and Installation
This section provides a general guide for installing the Bendix D865 CQ Brake Pad Set. Specific vehicle service manuals should be consulted for detailed, vehicle-specific instructions.
- Preparation: Park the vehicle on a level surface, engage the parking brake, and block the wheels. Loosen the lug nuts on the wheel(s) where brake pads will be replaced. Raise the vehicle and secure it with jack stands. Remove the wheel(s).
- Caliper Removal: Locate the caliper mounting bolts. Remove these bolts and carefully slide the caliper off the rotor. Do not let the caliper hang by the brake hose; support it with a wire or bungee cord.
- Old Pad Removal: Remove the old brake pads from the caliper bracket. Note their orientation for correct installation of the new pads.
- Caliper Piston Retraction: Use a C-clamp or a specialized caliper piston tool to slowly compress the caliper piston(s) back into the caliper body. This creates space for the thicker new pads. Open the brake fluid reservoir cap to prevent pressure buildup.
- Hardware Replacement: Replace any old brake hardware (clips, shims, etc.) with the new hardware included in the Bendix D865 CQ set. This is crucial for noise reduction and proper function.
- New Pad Installation: Install the new Bendix D865 CQ brake pads into the caliper bracket, ensuring they are correctly seated and oriented. The ceramic friction material should face the rotor.
- Caliper Reinstallation: Carefully slide the caliper back over the new pads and rotor. Reinstall and torque the caliper mounting bolts to the manufacturer's specifications.
- Final Steps: Reinstall the wheel(s) and torque the lug nuts. Lower the vehicle. Before driving, slowly pump the brake pedal several times until a firm pedal feel is achieved. Check the brake fluid level and top off if necessary.

4. Maintenance
While brake pads are wear items and require replacement, regular inspection of your braking system is essential for safety and performance.
- Regular Inspection: Inspect brake pads for wear every 10,000-15,000 miles or as recommended by your vehicle manufacturer. Look for uneven wear, cracks, or a friction material thickness below the minimum specification.
- Rotor Condition: Check brake rotors for excessive wear, scoring, or warping. Rotors should be resurfaced or replaced if they are below minimum thickness or severely damaged.
- Brake Fluid: Check brake fluid level regularly and ensure it is clean. Brake fluid should be flushed and replaced according to your vehicle's maintenance schedule.
- Hardware: Ensure all brake hardware is clean and free of corrosion. Lubricate caliper slide pins with appropriate high-temperature brake lubricant to ensure smooth caliper movement.
5. Troubleshooting
| Symptom | Possible Cause | Solution |
|---|---|---|
| Squealing/Grinding Noise | Improper installation, worn pads, missing shims, glazed rotors, foreign object. | Re-check installation, replace worn pads, ensure shims are present, inspect/resurface rotors, remove debris. |
| Vibration/Pulsation | Warped rotors, uneven pad wear, loose caliper. | Inspect/resurface/replace rotors, check pad wear, tighten caliper bolts. |
| Reduced Braking Performance | Worn pads, contaminated pads, air in brake lines, low brake fluid. | Replace pads, inspect for fluid leaks, bleed brake lines, top off fluid. |
| Excessive Brake Dust | Normal for some pad types, but excessive dust can indicate issues. | Bendix CQ pads are designed for less dust. If excessive, check for rotor wear or improper bedding. |
If troubleshooting steps do not resolve the issue, it is recommended to consult a certified automotive technician.
