Installation Guide

Safety First: Always wear appropriate personal protective equipment (PPE) including safety glasses and gloves. Ensure the vehicle is securely supported on jack stands on a level surface. Consult your vehicle's service manual for specific torque specifications and additional safety procedures.

Tools Required:

• Jack and Jack Stands
• Lug Wrench
• Socket Set and Ratchet
• Brake Caliper Compression Tool
• Wire Brush
• Brake Cleaner
• Torque Wrench
• Anti-seize Lubricant (optional, for hub)

Step-by-Step Installation:

1. Prepare the Vehicle: Park the vehicle on a level surface, engage the parking brake, and loosen the lug nuts on the rear wheels. Jack up the rear of the vehicle and secure it with jack stands. Remove the lug nuts and the wheel.
2. Remove Brake Caliper: Locate the two bolts securing the brake caliper to the caliper bracket. Use the appropriate socket to remove these bolts. Carefully slide the caliper off the rotor and support it with a wire or bungee cord to avoid stressing the brake hose. Do not let the caliper hang by the brake hose.
3. Remove Caliper Bracket: Remove the two larger bolts that secure the caliper bracket to the steering knuckle. Once removed, set the bracket aside.
4. Remove Old Rotor: The old brake rotor should now slide off the wheel hub. If it's stuck, gently tap around the hub area with a rubber mallet.
5. Clean Hub Surface: Use a wire brush to thoroughly clean any rust or debris from the wheel hub mounting surface. This ensures the new rotor sits flush. Apply a thin layer of anti-seize lubricant to the hub surface if desired, avoiding the lug studs.
6. Install New Rotor: Carefully slide the new Power Stop JBR1740 brake rotor onto the wheel hub. Ensure it sits flat against the hub.
7. Reinstall Caliper Bracket: Reattach the caliper bracket to the steering knuckle and tighten the bolts to the manufacturer's specified torque.
8. Install New Brake Pads (Recommended): While replacing rotors, it is highly recommended to install new brake pads. Insert the new brake pads into the caliper bracket.
9. Compress Caliper Piston: Use a brake caliper compression tool to push the caliper piston back into its bore. This creates space for the new, thicker brake pads and rotor.
10. Reinstall Caliper: Carefully slide the caliper back over the new pads and rotor. Reinstall the caliper bolts and tighten them to the manufacturer's specified torque.
11. Reinstall Wheel: Mount the wheel back onto the hub, hand-tighten the lug nuts, lower the vehicle, and then fully tighten the lug nuts to the manufacturer's specified torque in a star pattern.
12. Repeat for Other Side: Repeat the entire process for the other rear wheel.
13. Pump Brake Pedal: Before driving, pump the brake pedal several times until it feels firm. This seats the caliper pistons against the new pads and rotor. Check brake fluid level.

Operating & Break-In Procedure

While brake rotors do not have "operating" instructions in the traditional sense, proper break-in is crucial for optimal performance and longevity of both the new rotors and brake pads.

Brake Pad and Rotor Break-In (Bedding) Procedure:

This procedure helps transfer a thin, even layer of brake pad material onto the rotor surface, which is essential for proper braking performance and to prevent premature wear or noise.

1. Find a safe, open area where you can safely accelerate and brake without interruption.
2. Make 5-6 moderate stops from 40 mph down to 10 mph. Allow approximately 30 seconds between stops for the brakes to cool slightly. Do not come to a complete stop during these initial cycles.
3. Make 2-3 hard stops from 50 mph down to 10 mph. Again, allow approximately 30 seconds between stops.
4. After the last stop, drive for several minutes at a moderate speed without applying the brakes to allow them to cool down completely. Avoid heavy braking or coming to a complete stop with the brakes engaged immediately after the bedding process, as this can imprint pad material unevenly onto the hot rotor.

During the break-in period, you may notice some smoke or a burning smell. This is normal. After the bedding process, the brakes should feel firmer and more responsive.

Maintenance

Regular inspection and proper maintenance are key to ensuring the longevity and safe operation of your Power Stop brake rotors.

Routine Checks:

• Visual Inspection: Periodically inspect the rotor surface for signs of excessive wear, deep grooves, cracks, or discoloration (blue spots indicate overheating).
• Brake Pad Wear: Always check brake pad thickness when inspecting rotors. Worn pads can damage rotors.
• Rotor Thickness: Consult your vehicle's service manual for the minimum allowable rotor thickness. Rotors that are too thin should be replaced.
• Cleanliness: Keep the rotor surface free from oil, grease, or other contaminants. Use a dedicated brake cleaner if necessary.

Important Considerations:

• Avoid sudden, hard braking immediately after driving through deep water, as this can cause thermal shock and warp rotors.
• Ensure proper tire rotation and wheel balancing to prevent uneven wear on brake components.
• If you experience persistent brake noise, vibration, or reduced braking performance, have your brake system inspected by a qualified technician immediately.
