An important place in the brake system with hydraulics is occupied by cylinders. Thanks to them, the force is transferred from the pedal to the discs or pads through the fluid. In the event of malfunctions or leaks, the brake pedal fails, and the level of safety is sharply reduced. Failed mechanisms must be urgently replaced.
A wide range of suitable products from various manufacturers and brands is presented on the Russian market. This review will help you choose a durable reliable mechanism if you need to replace the original part.
Content
The brake cylinder is a component of the brake system that converts fluid pressure into mechanical energy that presses discs or pads against the wheel rim.
Depending on the purpose and design, there are:
1. Master cylinder:
One GTZ is installed in the car.
2. Wheel cylinder:
Usually the number of RTCs corresponds to the number of wheels, but it can be two or three times more when two or three devices are placed on one wheel.
Connection diagrams depend on the car drive:
1. Contours in front-wheel drive:
2. Contours in RWD:
If two RTCs are installed on each wheel in front, the connection can be combined. One will be in the first circuit, and the second - in the second circuit and will work simultaneously with the rear ones.
Varieties:
1. Number of circuits:
2. The presence of an amplifier:
Usually the GTZ is mounted on top of the cover of the vacuum booster. A fairly simple design includes:
Two pistons mounted one behind the other inside a hollow cast housing create the necessary pressure and form the working sections. Their return and retention in their initial position is provided by springs. The tank is designed for storage, as well as adding liquid when it decreases. Usually located on top, connected to the mechanism by bypass and compensation channels.
Liquid level control is carried out using marks on transparent walls. In addition, there is a sensor inside that, when the level drops, turns on the light on the instrument panel.
When braking, the front piston moves, blocking the compensation channel. Due to the resulting tightness, the pressure increases. The rear piston also moves, the liquid is compressed, and the compensation channel is blocked. The space behind the pistons is filled with liquid through open bypass channels. As a result of the increase in pressure, the RTCs are triggered, which actuate the actuators on the wheels.
When released, the pistons return to their original position under the action of the springs. The release of the brakes is performed smoothly due to the fluid remaining in the cavity behind the pistons and leaving there gradually. In the initial state, with an open compensation channel, the pressure is compared with atmospheric pressure.
Varieties:
With the onset of braking, the pressure increases, the incoming fluid moves the piston. In a drum system, the pistons move apart and press on the pads. In the disc mechanism, they are pulled out of the cavities with the pads pressed.
When the brake is released, the pressure decreases, the pistons return to their original position.
In order to avoid mistakes when choosing, you need to pay attention to the recommendations and advice of vehicle manufacturers. Indeed, when installing products of other types or models, the deterioration of the brake system is not excluded, which directly affects traffic safety. In addition, the following points must be taken into account:
Popular models and novelties can be bought in stores selling accessories and spare parts for cars. Consultants will tell you what devices are, how to choose, which company is better to buy, how much they cost, how they differ.
