Troubleshooting

Squealing noise during braking

Check if the brake pads are correctly seated and if anti-squeal shims are installed properly.

Vibration felt in the steering wheel or pedal

Ensure the wheel hub surface was thoroughly cleaned of rust/debris before installation and check that the disc is torqued to specifications.

Brake pedal feels spongy

This is often due to air in the hydraulic system rather than the disc; perform a brake fluid bleed.

Setup, Compatibility & Care

Before installation, ensure the vehicle's wheel hub is clean and free of rust or debris, as any surface unevenness can lead to lateral runout. Use a wire brush to clean the hub surface before mounting the new disc. Always replace brake discs in pairs across the same axle to maintain balanced braking forces. When installing, use the provided bolts and follow the torque specifications outlined in your vehicle's service manual. Periodic maintenance involves checking for unusual grooves or blue-tinted heat spots. Avoid using aggressive chemicals when cleaning the discs; a dedicated brake cleaner is recommended to remove shipping oils before initial use.
