Brake levers and calipers for bikes

Brake levers are essential components of a bicycle's braking system, allowing the rider to use the brakes effectively. They are produced in different sizes and designs, while each of them has its own characteristics and advantages.

Modern brake levers are often designed with ergonomics in mind and offer comfortable shapes and materials that reduce hand fatigue during long drives. Many come with adjustable features such as range settings. This allows riders to fine-tune the lever position to suit their hand size and riding preferences, increasing comfort and improving control.

Regular inspection and maintenance of brake levers is important to ensure their proper function and safety in use. Check whether they are not worn, their parts are loose, the cable is properly tensioned or there is enough brake fluid in the reservoir.

Brake calipers are an equally important part of the bicycle braking system. Calipers are responsible for slowing down the bike by putting pressure on the brake disc, which creates friction and slows the bike down. They are mounted near the wheel hubs and have two opposing pistons. With hydraulic disc brakes, when the brake lever is pressed, hydraulic fluid is used to compress the pistons, which press the brake pads onto the rotor, which is attached to the wheel hub. With mechanical brakes, the pistons are compressed using the brake cable.

What are the common problems with brake calipers?

Common brake caliper issues include squealing or screeching brakes, poor braking performance, uneven brake pad wear, stuck caliper pistons, and leaking hydraulic fluid (for hydraulic disc brakes). These issues can often be solved by proper cleaning, adjustment or component replacement.

Are brake calipers compatible with every bike?

Brake calipers are not universally compatible with all types of bicycle frames. Compatibility depends on mounting system (Post mount, Flat mount) and frame or fork specifications. It is important to check the manufacturer's instructions and consult a professional mechanic to ensure compatibility, which is also achieved with adapters.

How to determine the correct position of the brake levers?

The correct position of the brake levers depends on personal preferences and driving style. However, a general guideline is to position the brake levers so that you can comfortably reach and press them without straining your hands or wrists. Experiment with different positions and angles to find the most comfortable and ergonomic setting.

Are there different sizes of brake levers?

Brake levers come in a variety of sizes to suit riders with different hand sizes and preferences. Some brake levers offer adjustable reach or different lever lengths to better accommodate the rider. It is important to choose brake levers that are suitable for your hand size and provide a comfortable grip and reach.
