Brakes 37 www.aftermarketonline.net MAY 2025 Installation best practice for pads and discs For independent technicians, replacing brake discs and pads is a routine but important task. However, Comline tells Aftermarket there are scenarios that can test even the most experienced professionals. Rusted components, warped hubs, compatibility and strange vibrations are just some of the issues technicians can face in workshops. Here are eight identified problems and their solutions: Rust and corrosion Problem: Rust can build up on brake discs, often because of moisture or road salt, which can make removing the discs from the hub difficult. Solution: Apply penetrating oil, use a rubber mallet or a specialised puller. In severe cases, carefully apply heat to loosen the disc. Future issues can be prevented by fitting Comline coated discs, which feature an anticorrosion coating. Seized or stuck fasteners Bolts or screws may seize due to rust or overtightening. Use penetrating oil, an impact driver or heat to free the fasteners. As a last resort, try drilling them out! Damaged or warped hubs If a hub is dirty or uneven, this can result in improper disc seating, causing wobble or vibration during braking. Clean the hub with a wire brush or abrasive paper. Check for runout using a dial gauge. For severely damaged hubs, replace them with a Comline hub assembly, which comes as a complete kit. Incorrect installation Misalignment or failure to torque bolts properly can lead to uneven braking or damage. Follow the manufacturer’s installation procedures and use a torque wrench. Brake pad issues Combining old or incompatible brake pads with new discs can cause uneven wear or poor performance. Always install new brake pads when replacing discs and fit them using axle sets. Comline’s R-90 approved brake pads complement its coated discs for outstanding stopping power.
