For independent technicians, replacing brake discs and pads is a routine but important task. Yet Comline believes there are scenarios that can test even the most experienced professionals. Below,  Comline’s experts offer solutions to challenges, designed to ensure best practice and customer satisfaction.

Rusted components, warped hubs, compatibility issues and strange vibrations are just some of the symptoms and challenges technicians can face on the workshop floor. Here are eight identified common problems and their solutions:

• Rust and corrosion… Problem: Rust can buildup 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 anti-corrosion coating that prevents rust and makes the replacement process simpler.
• Seized or stuck fasteners…Problem: Bolts or screws may seize due to rust or overtightening. Solution: Use penetrating oil, an impact driver or heat to free the fasteners. As a last resort, try drilling them out. 
• Damaged or warped hubs…Problem: If a hub is dirty or uneven, this can result in improper disc seating, causing wobble or vibration during braking. Solution: 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 for a simple fit.
• Incorrect installation…Problem: Misalignment or failure to torque bolts properly can lead to uneven braking or damage. Solution: Follow the manufacturer’s installation procedures and always use a torque wrench.
• Brake pad issues… Problem: Combining old or incompatible brake pads with new discs can cause uneven wear or poor performance. Solution: 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.
• Runout and vibrations…Problem: Excessive runout, when new discs are installed, can cause brake judder. Solution: Measure for runout and replace any components causing misalignment.
• Underlying issues…Problem: Hidden problems, such as wheel bearing failure or improper alignment, can lead to repeated failures.Solution: Inspect the entire brake and wheel assembly system to ensure bearings, alignment and hydraulics are in good condition. 
• Post-installation issues…Problem: Motorists may hear noise, feel vibration or experience reduced efficiency if the bedding-in process isn’t followed correctly. Solution: Communicate clearly with customers on the proper bedding-in techniques – in short, observing gradual, progressive braking within the first 200 miles post-installation Furthermore, choosing Comline brake pads, featuring a resin-based layer that strengthens braking performance during the bedding-in period, will improve braking efficiency from point of fitment.

Comline’s braking range features exclusive friction materials and durable components crafted from premium raw materials, produced in internationally renowned manufacturing facilities. Its brake pads, for example, incorporate Noise Control Technology and exceed aftermarket standards, undergoing rigorous testing beyond R90 regulations to ensure exceptional stopping power.

Comline’s coated discs, meanwhile, are finished with a specialised coating, enhancing aesthetics, corrosion resistance and helping a fast, simple fit. Its calipers are exclusively new units made from robust cast iron or lightweight aluminium, delivering reliable braking performance and impeccable fitment for the installer.
