Brake noise Toyota Corolla E170

Brake Noise in Toyota Corolla E170 (2013-2019)

Brake noise in vehicles can be indicative of various issues ranging from minor to severe. Addressing these noises promptly is crucial for safety and vehicle maintenance.

Tools Required

• Jack and Jack Stands
• Lug Wrench
• Torque Wrench
• Brake Pad Thickness Gauge
• Flashlight
• Safety Glasses and Gloves

Procedure

1. Initial Inspection:

   • Visual Check: Look through the wheel spokes or remove the wheel to visually inspect the brake pads and rotors.
   • Pad Thickness: Use a brake pad thickness gauge to measure the remaining pad material. Pads should be replaced if they are below 3mm.

2. Listen for Noise Source:

   • Drive the vehicle at a low speed in a safe area and lightly apply the brakes to identify the source and type of noise.

3. Inspect Brake Components:

   • Remove the Wheel: Use a lug wrench to remove the wheel nuts and take off the wheel.
   • Inspect Pads and Rotors:
     • Look for uneven wear, glazing, or scoring on the pads and rotors.
     • Check for rust or debris that might be causing noise.

4. Check Brake Hardware:

   • Inspect brake caliper, caliper brackets, and mounting hardware for looseness or damage.
   • Ensure the anti-rattle clips are in place and functional.

5. Rotor Inspection:

   • Use a flashlight to inspect the rotor surface for significant grooves or scoring that might cause noise.
   • Check rotor thickness with a micrometer. Compare against the manufacturer's specifications.

Repair Instructions

Tools Required

• Brake Cleaner
• New Brake Pads (if required)
• New Rotors (if required)
• Anti-Squeal Compound
• Brake Grease
• C-Clamp or Brake Piston Tool

Procedure

1. Replace Worn Brake Pads:

   • If pads are below the minimum thickness, replace them.
   • Compress brake caliper piston using a C-clamp or brake piston tool before installing new pads.

2. Replace or Resurface Rotors:

   • If rotors are damaged or below minimum thickness, replace them.
   • If rotors are in good condition but slightly scored, consider resurfacing them.

3. Apply Anti-Squeal Compound:

   • Apply anti-squeal compound to the back of the brake pads to minimize noise.

4. Lubricate Brake Components:

   • Apply brake grease to the caliper pins and any moving parts to ensure smooth operation.

5. Reassemble Brake Components:

   • Carefully reassemble the brake components ensuring all hardware is securely fastened.
   • Torque the wheel nuts to the manufacturer’s specifications.

6. Test Drive:

   • Conduct a test drive to ensure the noise has been resolved and the brakes function correctly.

Conclusion

Brake noise in the Toyota Corolla E170 can often be resolved by addressing worn brake pads, resurfacing or replacing rotors, and ensuring that all brake components are properly lubricated and installed. Regular inspection and maintenance of the braking system can prevent these issues from arising. Always follow manufacturer guidelines and safety procedures during inspection and repair.
