Drum brakes can be classified into internally expanding type and externally contracting type based on the direction of movement of the brake shoes. Below is an introduction to the related aspects of brakes: Working Principle: Brakes provide resistance to stop a vehicle. The handbrake or parking gear in an automatic transmission serves as the vehicle's brake. The braking system used in cars is an electronic parking brake system, which combines temporary braking during driving with prolonged braking after stopping, controlled electronically. The working principle of parking brakes, whether electronic or mechanical handbrakes, involves generating friction between the brake pads and brake discs to achieve the braking effect. Types of Brakes: Generally, vehicle brakes can be divided into drum brakes and disc brakes. Small vehicles typically use drum brakes, also known as drum brake systems.

How to Fold Down the Rear Seats in the Cavalier?

The rear seats of the Cavalier cannot be folded down. Below is a detailed tutorial on how to remove the rear seats of the Cavalier: 1. First, use a 17mm socket or wrench to remove the seat back fixing screws from the rear trunk. You can find the 17mm socket or wrench in the vehicle's tool kit. Except for the base model Xianxiang version, which does not come with a tire removal wrench or spare tire, the mid and high-end models are equipped with these tools. Lift the trunk floor mat, take out the wrench, and loosen the rear seat back fixing screws. 2. The rear seat cushion also has two clips. No tools are needed to remove the cushion from the clips. Simply lift both sides of the cushion upwards. It is best to have two people cooperate for this step, as the clips' hooks can be easily released. Finally, pull the cushion out of the clips.

How to Replace the Air Conditioning Filter in the Golf VII?

Method for replacing the air conditioning filter: 1. The air conditioning filter in the Golf VII is located behind the glove box, which differs from the position in the Golf VI. The glove box needs to be removed. 2. Open the glove box, and at the junction where the two curved sides meet the top horizontal part, there are two buttons. Press them upwards and inwards until they reach the bottom, then gently pull the box outward to detach it. 3. After the box is detached, you can see the filter's cover plate, which has six hooks—three on the top edge and three on the bottom edge. Only the top edge needs to be opened. Insert a flat-head screwdriver and gently press down to release the hooks. Once the top edge is released, lift it upwards to remove the cover plate. 4. After replacing the filter, cover it with the filter plate and secure it in place. 5. Reinstall the glove box. During reassembly, first insert the damping guide rail into the damper, then press the buttons to reattach the left and right clips of the box. Below are some tips for replacing the filter: (1) If the airflow from the air conditioner significantly decreases, the air conditioning filter may be clogged. First, clean the filter or replace it if necessary. (2) The frequency of cleaning depends on road conditions, and it is recommended to clean it earlier rather than later. (3) The air conditioning filter should be correctly installed in its position. Using the air conditioner without the filter may degrade dustproof performance and affect air conditioning performance.
