Depending on the vehicle type, it is divided into two types: air brake master cylinders and hydraulic brake master cylinders. Generally, passenger vehicles mostly use hydraulic brake master cylinders, while commercial vehicles typically use air brake master cylinders. 2.

What are the symptoms of a broken suspension bushing?

Symptoms of a broken suspension bushing include: 1. Hearing a metallic clanging sound when going over speed bumps, cobblestone roads, or dirt roads; 2. Continuous unusual noises on roads with large potholes; 3. If the damage is severe, it will continuously transmit minor vibrations to the steering wheel. The purpose of the bushing is to prevent vibrations and noise. If there are unusual noises when driving on uneven roads, it should be replaced promptly. The hard connection between the suspension and other metal parts relies on the bushing to buffer vibrations and noise between the metals. If the bushing is aged, it cannot function as a shock absorber, leading to metal parts colliding and producing unusual noises, which in turn affects the vehicle's stability and buffering capability during driving.

Where is the fuel tank located in a sedan?

The fuel tank of a sedan is generally positioned towards the middle-rear section of the vehicle. However, depending on the model, some fuel tanks are located on the right side while others on the left. This applies to most vehicles, though there are exceptions. For instance, the Honda Fit hatchback has its fuel tank positioned in the middle of the car, essentially beneath the driver's seat, to maximize rear passenger space. The placement of the fuel filler neck considers not only refueling convenience but also safety factors. If you can't remember the location of the fuel filler neck, check the fuel gauge on the dashboard—the small arrow indicates which side it's on. Vehicles with a single exhaust pipe typically have the exhaust pipe positioned opposite to the fuel tank.
