Toyota Sequoia brake calipers sticking causing sudden braking on the freeway on Toyota Sequoia

Some Toyota Sequoia owners report experiencing issues with stuck brake calipers, which can lead to sudden braking while driving on the freeway. This problem may cause a loss of fuel mileage and pulling to one side, particularly if one brake is affected, resulting in the vehicle veering in that direction. The sticking of brake calipers is often attributed to corrosion, rust, or road debris that hinder the proper retraction of caliper pistons, keeping brake pads in constant contact with the rotor. Additionally, a stuck brake caliper can prevent brake pads from fully disengaging, leading to excessive friction and heat buildup that may damage various brake components, including pads, rotors, and calipers themselves. Some owners also find that swollen rubber brake lines can act as a "check valve," preventing the caliper from releasing, which can be identified by drag or resistance when attempting to turn the wheel after applying the brakes. It is crucial for owners experiencing these issues to seek professional inspection and repair to ensure safety and prevent further damage to the braking system.
