What exactly are hydraulic brakes? A hydraulic brake is a mechanical arrangement of braking system that uses brake fluids, usually containing either ethyl or methanol, to transmit pressure from the braking system to the stopping system. These fluids are usually supplied by the brake system to a hydraulic system fitted into the brake assembly. The hydraulic system, in turn, applies hydraulic pressure to the brake discs to apply pressure to the brake pedal and to absorb any energy that the driver applies to the foot brake. Hydraulic brakes can also be manual, meaning that the driver does have to apply pressure to and release pressure from the foot brake lever in order to slow the car.
In an automatic bicycle, the system which contains the hydraulic brakes is often a disk-type assembly fitted to the frame of the mountain bike. It has been found that when the disks are made out of carbon fibre this material provides better braking performance than the standard steel. The advantage of this is that the discs have a small amount of weight, as little as one quarter of a gram, making them light enough to be mounted on a lightweight machine, but with an extremely high torque for maximum stopping power.
The disks of the hydraulic brakes are connected to the piston and cylinder by means of hoses. The hoses carry hydraulic fluids to and from the calipers and caliper boots through a range of gears and oil seals. There are two main types of hoses: pressure hoses, which allow a higher volume of hydraulic fluid to pass through the hose; and heat-resistant hoses, which protect the hydraulic components against heat damage. Hydraulic hoses and drums are made out of polyester fabric, typically in Nylon, although Nylon is becoming more commonly used due to its extreme durability and ability to withstand heat.
Another important component of hydraulic brakes is the brake control unit. This is the heart of the system and is usually made out of a single piece of material, usually aluminum. The part has an actuator on one side that pushes the brake fluids up through the caliper and onto the rotor. On the other side of the actuator there is a disc that is able to withstand high temperatures and friction. The disc then slows the hydraulic flow, which is matched to the brake fade as determined by the pressure gauge.
Brakes pedals in hydraulic brakes are different to conventional rotors in other ways, as well. A brake pedal is actually a screw driven by a bolt into a hole in the master cylinder. The brake pedal assembly is then mounted to the rotor and rotors using bolts, and there are usually three rotors on each brake pedal. The design of the brake pedal assembly means that once the bolt has been seated into the master cylinder, it cannot be turned, which means there is no chance of a seal becoming damaged. These brake pads are also designed to have a sealed surface, so that the control levers do not slip.
It should be noted that some passenger vehicles have hydraulic brakes, which use counterweights instead of disks or casings to achieve braking power. Hydraulic systems are available in three different sizes and there are six different series. All of the sizes come with different flexing and range of operation. There are five different resistance levels: low, medium, high and very high. Although there is no correlation between horsepower and hydraulic efficiency, the higher the hydraulic fluid flow, the lower the resistance of the discs.
