What is the reason for the front wheel brakes of the Cruze not retracting after heating up?

[VonArya]

The reason for the front wheel brakes of the Cruze not retracting after heating up is that the brake fluid is too dirty, the internal valve of the master cylinder is stuck, the free clearance is too small, the piston of the wheel cylinder does not return to the center point, or the return spring has failed, all of which can cause incomplete brake retraction. Here is some additional information: 1. Appearance: The Cruze will offer six body colors: Polar White, Obsidian Black, Cold Platinum Silver, Glacier Blue, Titanium Gray, and Flame Red, as well as four interior color schemes: Starry Dark Gray, Brocade Dark Gray, Matte Gray-Black, and Saddle Brown. The 1.5L automatic Xuanfeng version is equipped with leather seats and a leather steering wheel. 2. Powertrain: The new car will continue to be equipped with 1.5L and 1.4T engines, with maximum power outputs of 114 horsepower and 150 horsepower, respectively. In terms of the transmission system, the 1.4T model will be paired with a 7-speed dual-clutch transmission, while the 1.5L model will be matched with a 6-speed automatic transmission and a 6-speed manual transmission.
