You probably know exactly what to use a trailer withoutbraking systemquite risky. Of course, according to all technical regulations, it is permissible not to install brakes on a trailer with a load capacity of up to 750 kg. But who said that 100% of the time a situation will not arise when brakes will be extremely necessary. It is because of this that experienced car owners and trailer users are interested in how to make and connect brakes to a trailer.
How to connect brakes on a trailer?
It's quite simple, provided that the trailer is purchased immediately with the brake system installed and the electronics connected correctly. Then it is necessary to connect only the outlet with the car plug and that's it. According to the standards, there can be 7-pin and 13-pin connections. But as for manual connection, it is more difficult here.
It is necessary to have a complete set of braking system available:
- the brake itself;
- a suitable set of connection wires;
- brake pads, if they are not previously installed;
- connection diagram of contacts to the outlet;
- 7-pin or 13-pin socket (European standards).
The most difficult part of this whole process is the correct connection of the power contacts. Here it is important to remember that the socket or plug (depending on the previous installation on the car) must meet the standards. In no case can you connect a 13-pin socket to a 7-pin plug or vice versa. In this case, you can use only a special adapter, but it is better to connect the corresponding element of the plug to the outlet.

Reasons for installing a brake on a trailer
The road surface is not always perfectly flat, as you would like, and it is dangerous to drive a car with an uncontrolled towing device, especially on steep turns and descents. To prevent a possible emergency situation, it is better to install a controlled braking systemon a trailer. After all, there are a number of factors that can lead to a road traffic accident:
- bad weather conditions;
- road irregularities;
- driving on rough terrain without a suitable road surface;
- steep descents and ascents while driving;
- the trailer may be overloaded.
All this perfectly illustrates the situation why exactly the brake system of the trailer can save you. Everything is simpler than simple, because during movement, braking of the car occurs in a coordinated manner and the car itself stops under its own weight. And when there is a towing device, it is not able to stop without pressing the brake lever. Therefore, the trailer continues to roll at the same speed as during movement and pushes the car with this force. Accordingly, a car collides with a trailer, where the rear part of the car, the trailer, its contents and the braking system will already be damaged.
When you squeeze the gas pedal to all possible limits, it destroys the brake pads and not only that, so it may be necessary to make repair adjustments, and it is more cost-effective to pre-connect the brakes to the trailer.
Do-it-yourself brake
How to make brakes on a car trailer with your own hands is of interest to almost every driver who has a towing device in use. However, you should not start work if you are not confident in its performance, then it is better to contact specialists. If you still do it on your own, then be careful and work, observing all safety rules during such rather difficult work.
It is worth starting with the selection of the necessary spare parts and components for installing the brake. You will need:
- roll brake rod - a braking mechanism that transmits the thrust force to the transmission lever;
- traction and transmission lever, with the help of which the cable is stretched;
- brake pads to ensure proper wheel braking;
- brake cables that transmit the braking impulse to the pads.
It is better to buy all these components from the best brands. Our online store offers you to choose the best proven parts that have been proven by users to be durable and reliable in operation. OnVnedorognikyou will find everything you need.
When installing the design of the braking system, it will be necessary to pre-adjust the trailer itself and spend enough time and effort for the entire work process. Follow the rules on how to make a trailer brake.
- Turn the trailer over first. This will allow you to work comfortably, and most importantly, correctly and accurately.
- In most cases, the drawbar is too long to install a brake, so it is worth taking measurements and cutting off a piece to replace it with a roll brake.
- Next is the turn of the wheels and fixing brake pads and drums on them.
- You still need an axle equipped with brake cables or equip an existing one. In order to equip the existing axle, you only need to connect the brake cables to the pads, and from them extend them to the traction after fixing them and attach them to the balance on the rolling brake.
- Only after fully winding the cables and checking the operation of the brakes can you install the plug and connect it to the car socket and tow bar.
