ABC mechanic: adjustment of brakes on a bicycle

Walking in the open air, of course, allows you to have a great rest and gain strength, and if you can ride a bicycle, you can be sure that this will double the pleasure. In addition, riding on this iron "friend" will allow you to gain a good physical shape, as well as improve immunity to various types of diseases and get rid of chronic fatigue. But for this vehicle to work without fail, it is necessary to know such repair details as tire replacement, bicycle brakes adjustment and others. These moments are important, but it is not so difficult to implement them, having some skills in working with mechanisms.

Types of brake systems

There are several types of brake systems for bicycles:

• Rim - mechanical (vector, tick, cantilever) and hydraulic;
• Pedal;
• Disk - hydraulic, mechanical and combined;
• Roller;
• Drum and stirrup.

Of these, only the first three systems were widely used. It can be noted that the adjustment of brakes on a bicycle differs from the type used. Consider the most common cases - rim and disc brakes.

Disk systems

The disc brake system is a device including a rotor made in the form of a steel disc and a caliper. The latter device is a tick brake, the pads of which compress the plate. The force from the brake lever goes to this mechanism by means of a cable (mechanic) or by means of hydraulics.

Adjustment of brakes on a bicycle with a disk system can be carried out as follows:

1. It is necessary to install the disc on the wheel hub and secure with the eccentric bolts.
2. Connect the adapter and caliper so that the last element does not fit snugly.
3. Pressing the brake handles, you need to adjust the position of the pads, in which they go to an equal distance.
4. When the rotor is clamped, the caliper is automatically positioned in the correct place, and only then it is necessary to fix this part with bolts.
5. Check brake pads for operation. To do this, the wheel is scrolled, pressing the handle of the system several times (more than 20). In the case of friction of the rotor on the shoe (on the one hand), it is necessary to loosen the caliper attachment and to move in the direction of this bar. If this phenomenon is two-sided, here it is necessary to loosen the hexagon on the handle and tighten all the bolts.

Rim systems

Adjusting the brakes on a bicycle with a rim system involves two steps:

1. Setting the front panel.
2. Rear brake system adjustment.

The position of the handles can be adjusted according to individual parameters, so that it is convenient when you press this device. To do this, you need a screw, with which this part is attached to the handlebar, slightly loosen. Then adjust the position of the handle and secure the element.

Adjustment of the handbrake is carried out in such a way that the pads are located at an equal distance from the rim (about 3 mm). This can be achieved by weakening the tension of the compression spring on the side of a weaker tension or reinforcing it from the other side.

The rear brakes are adjusted in the same way. Checking and adjusting the operation of this system will increase the lifespan of the bicycle, as well as secure traffic on this type of transport.
