The towing of a boat, like our own car, requires for its proper operation to carry out regular checks of its condition, re-tightening screws and lubricating the moving parts, paying special attention to the pressures of the tires, the state of the bearings or the effectiveness of the braking system, if any. On this basis, we are going to offer some basic tips that will allow us to take our trailer with greater safety, although we should not forget to do an annual review through the authorized dealer of the brand that we are using. BRAKES: - The function of the trailer brakes is to stop the rotation of the wheels and with it the movement of the vehicle. The classic main elements that make up the braking system are the braking element and its control. BRAKING ELEMENT - The trailer brakes element consists of a fixed part fixed to the frame and, on the other hand, integral with the wheels. The fixed part is a disc or plate on which they mount semicircular shoes, covered externally by a rough or resistant material, in order to be "grabbing" firmly to the drum and do not slip about him. The shoes are articulated at one of their ends by an axis fixed to the plate. The other ends are free, being able to be separated by turning on their axis to which they are articulated, being held together by a spring applied on their interior surfaces. The movable part of the braking element is a drum opened by one of its faces and fixed to the disc of the wheel by the other. In the center of the drum is the hub of the wheel inside which the hub. The drum covers the fixed part of the braking element so that its cylindrical surface and that of the shoes are concentric and very close but not touching. When braking is done by expanding (opening) the brake shoes, which thus oppress the drum, it is called expansion braking. The most common type of brake is the expansion brake. Its foundation is that semicircular pads are opened or closed by oppressing or not the drum and, therefore, whether or not the braking of the vehicle is produced. The control of the braking element can be: mechanical, hydraulic or by compressed air. TRAILER BRAKE CONDITIONS: - The conditions that must meet the brakes, whatever the system are: - Do not block the wheels to prevent slipping. The brakes stop the wheels, but who stops the vehicle are the tires - They must be of progressive action in agreement with the route of the pedal of the brake. Abrupt braking can cause skidding with loss of steering control. - The braking intensity must be equal on the wheels of the same axle, otherwise, the steering will pull towards the braked one. As the weight of the vehicle is loaded on the front wheels, the braking force will be slightly higher than the rear wheels. - The pads must not rub against the drum if the brake pedal is not actuated. The existing braking systems are mechanical (little used), hydraulic, compressed air and electric.
