On this page, we would like to inform you about the very important topic of brake service.
Brakes, brake discs & brake pads
In a car, intact brakes are, of course, enormously important. Many cars are equipped with disc brakes (front axle) and drum brakes (rear axle). The disc brakes consist of steel discs. Above it is the so-called brake calliper. It consists of a piston, which presses the brake shoes on both sides of the brake disc. Brake pads are located on the brake shoes which produce a high friction resistance during braking.
The drum brakes are equipped with brake shoes that are pressed against the drums from the inside. To ensure that the driver does not have to exert any great force on the brake pedal when braking, the brakes are hydraulically supported. The brake fluid is used to transmit the force. Modern vehicles are also equipped with brake force distributors and anti-lock systems, or ABS. With these technical aids, the braking force is distributed optimally to all four wheels, so that it is no longer possible to block individual wheels.
Change brake pads
A certain amount of wear is produced by the friction on the brakes. The brake pads wear out first. Replacement in a car repair shop is usually done quickly. However, the brake pads should always be replaced on both wheels of one axle. Only in this way an even braking effect can be ensured. After replacing the brake pads, the brakes must also be adjusted accurately.
Change brake disc
However, sometimes severe wear on the brake discs can also occur. This is often the case when the brake pads are worn over an extended period. This results in deep grooves in the brake disks. These influence the braking effect negatively. It is, therefore, better to have the brake discs exchanged. This work should also be carried out on both wheels of an axle. Replacing the two brake discs and replacing the brake pads will cost a bit more, but the safety of a car should never be compromised.
Replace brake fluid
In some cases, the brake fluid must also be renewed. The reason for this is that the brake fluid has a hygroscopic property. This means that the brake fluid can absorb and bind moisture in the air. This creates water in the brake fluid. Since the water becomes gaseous when heated, bubbles are formed in the liquid which can no longer transmit any force. This phenomenon is extremely dangerous. It is expressed in the form that there is no longer a braking effect at all. The driver can press the brake pedal as far as it will go without causing any braking effect. For this reason, the brake fluid should be replaced after ten years at the latest. In a well-equipped workshop like ML Tyres and Autocare, changing the brake fluid is not a big problem. First of all, the ventilation screws are opened on all four wheel brake cylinders, and the collecting container is placed underneath. With a special device, new brake fluid is then pumped into the storage tank. At the same time, the old brake fluid is pressed out. Finally, the vent screws are tightened again. The whole process takes about half an hour.
