Brake calipers typically degrade gradually, making it challenging to promptly detect potential issues. Vehicle owners often remain unaware of initial signs, such as damage to rubber seals caused by friction or contamination. When the secondary seal sustains damage, piston corrosion can rapidly occur, resulting in impaired functionality. The initial noticeable indication is a distinct odor emanating from the affected wheel. At this point, drivers should inspect the brake system’s condition. Failure to take appropriate corrective action may lead to complete caliper blockage.
Indications of malfunctioning brake calipers include:
- Brake pedal vibration during braking
- Steering wheel vibration during braking
- Difficulty maintaining the intended direction
- Pulling to one side when braking
- Audible noises during braking
If any symptoms indicating damage or wear of braking system components arise in the car, it’s advisable to promptly visit a service center and assess the condition of these parts. Neglecting such issues can potentially lead to further failures, escalating repair costs.
In such instances, refurbishing or replacing the brake caliper becomes necessary. The decision to refurbish typically hinges on the extent of wear. Often, corrosion manifests, which can be effectively addressed by surface grinding. This process restores the caliper’s functionality to its previous state. However, if corrosion has caused substantial damage, acquiring a kit with a new plunger might be required.
Corrosion may also affect the guide, commonly due to rubber cover deterioration. This leads to increased friction in the guide, resulting in operational irregularities with the caliper.
Early intervention upon noticing initial symptoms may involve merely cleaning the guides and fitting new seals during refurbishment. Delaying action, however, risks causing permanent damage, such as guide jamming in the caliper yoke, necessitating the purchase of a new brake caliper.
