The “V-brake” is a type of brake used on most bikes. C ?? ‘is a system in which two calipers with two pads come closer to the rim of the wheel. The friction between the brake pad and the rim causes the bike to brake.

The brake pad is the part of the brake that approaches the rim of a wheel to make it brake.

The bicycle thus brakes by the friction of this pad, which therefore is used over time. If your bike does not brake well, it may be because of the wear of this pad that must be regularly checked and changed.

The rim is the part of a wheel on which the brake pads rub. The rim is the solid circle of the wheel. Some high-end rims can not be used with V-brake brakes (but only with disc brakes) because they do not have flat sides on which the brake pads can rub.

How do I know if my brake is incorrectly adjusted?

It can be easily detected if a brake is properly adjusted. In the normal position, the brake pad must not touch the rim but must be relatively close to the edge. The two brake pads must be at the same distance from the rim and must be parallel to the rim.

When braking, the two brake pads must stick to the edge at the same time, must not be too low (in a vacuum) or too high (touch the tire) but perfectly aligned with the side of the wheel. If this is not the case, your brakes will not give the best of themselves and may even be dangerous if your bike does not brake appropriately.

Brake adjustments

Position of the brake pads

The brake pads must be placed in such a way as to brake as best as possible and thus to be able to tighten the wheel as efficiently as possible.

With your Allen wrench, you can re-center, rotate, lower or mount the brake pad so that it fits perfectly to the rim when in a braking position. It must be properly aligned, and the entire brake pad area must touch the edge, without touching the tire or in a vacuum.

Brake lever

On your brake lever, at the front on the handlebars of your bike, you may not be able to do so. Tighten the cable fully by turning the cone or washer Plastic or metal) which will prevent your brake from having problems rolling.

Bring the brake pads closer to the rim

It is necessary that the brake pads are not too far from the rim for maximum braking power. The ideal is to have a distance of 1 or 2 mm between the brake pad and the rim when not braking.
To play the distance between the pads, you can play the range of the brake cable. The shorter the cable, the closer the brake pads will be to the rim and vice versa.
To reduce or increase the distance of the cable, loosen the screw holding the cable with an Allen wrench (to 55s on the video). Tighten the cable more or less so that your brake pads Close to the rim without touching it.

If the tension is too strong and you can not hold the cable with your hand while tightening the screw, you can use a clamp to hold the cable.

Adjusting the spring tension

If your skates are off-center (e.g., one is very close to the rim, the other is distant), there is a small screw on the brake caliper (see video) that the ?? You can tighten or loosen and re-center the shoes properly.

Small final detail for some, do not hesitate to fold the end of the cable
