Here are the reasons for the sudden stiffness and inability to press the brake when reversing: Reason: One is a problem with the vacuum booster pump, making it difficult to press the brake without assistance. Another situation is that after the engine is turned off, the brake is pressed again, depleting the vacuum created by the vacuum booster pump, and subsequent braking relies solely on manual force. Related introduction to brakes: The brake is a mechanical braking device that can slow down the vehicle speed. Simply put: The car brake pedal is located under the steering wheel. Pressing the brake pedal causes the brake lever linkage to be pressurized and transmitted to the brake pads on the brake drum, clamping the brake disc to slow down or stop the car. The manual brake in a car is located next to the gear shift, connected to the brake lever.

What Causes a Car to Lack Power When Climbing Hills?

There are several reasons why a car may experience a decrease in power and struggle when climbing hills, aside from severe engine carbon buildup. These include excessively high engine temperature, engine misfire, and poor fuel quality. Below is a detailed analysis: 1. Excessively High Engine Temperature: When the car detects that the engine temperature is too high, it will automatically reduce power to decrease the engine's load. As a result, the car may exhibit symptoms of reduced power and difficulty climbing hills. This is a normal phenomenon, and the issue will resolve once the engine temperature drops. 2. Engine Misfire: There are many potential causes for an engine misfire, and a detailed inspection at a repair shop or 4S store is necessary to determine the specific issue. 3. Poor Fuel Quality: If the fuel added to the car is of low quality, the engine cannot perform at its maximum efficiency, leading to a lack of power. In this case, simply switching to higher-quality fuel should resolve the problem.
