Mazda CX-5 rear brake failure with rust and shimmy issues after 32k miles on Mazda CX-5

Some Mazda CX-5 owners report experiencing rear brake issues, particularly with rust and shimmy problems after 32,000 miles. These owners have noted that rear brake pads and rotors may need replacement due to rust even after regular dealership servicing. Additionally, some have encountered rear brake calipers locking up, which poses a significant safety concern. Uneven wear across the width of the rear brake discs has also been observed, suggesting potential issues with brake components. Furthermore, warped front rotors can lead to steering wheel vibrations, while warped rear rotors may cause pulsation felt in the seat or from the back of the vehicle. Signs of heat damage on brake pads, such as shiny surfaces or flaking paint, indicate a need for replacement, as dragging brake pads can create excessive heat and potentially warp the rotors, resulting in brake judder. These issues underscore the necessity for regular maintenance and inspection of the rear brake components in Mazda CX-5 vehicles to ensure safe and reliable operation.
