The braking system of an automobile is perhaps the most essential part responsible for inhibiting its motion in a controlled manner. This system incorporates many parts which work in a coordinated manner to slow down the vehicle. Over time braking systems have evolved and today vary from the traditional drum brake systems to electronically assisted systems. Different types of braking systems can be seen in different vehicles depending upon the manufacturer and type of vehicle, and thus different sub components. Most Honda brake systems are the disk brake type.
Drum brakes use a pair of shoes fixed inside the drum in such a way that they are pressed against the inner surface when the driver pushes the brake pedal. The drum being attached to the rim slows down the vehicle. Generally a single double-acting hydraulic cylinder connected to the pedal is used to actuate the shoes. The pedal cylinder system exploits the mechanical advantage, thereby multiplying the force being transmitted. There is also a device called the brake adjuster inside the drum which maintains an optimum distance between the shoe-drum interface. Most vehicles incorporate a emergency brake lever, which again uses the same shoes for its functioning. When the emergency brake is actuated the cable connected to it pulls a lever connected to a shoe thereby stopping the car. This feature is also useful to park vehicles on slopes. These types are only usually found in older Honda braking systems, usually seventies and early eighties models.
Disc brake are now the new technological trend in automotive braking, which is nothing but a modernized version of the simple bicycle brake. Luckily all modern Honda braking systems are made up of disk brakes as they offer a massive increase in performance. These comprise of a brake disc or rotor mounted on the hub and a pair of brake pads fixed onto the brake caliper. The caliper receives a brake line from the master cylinder which in turn is connected to the pedal. The caliper can generally slide from side to side and is self centering. In the case of motorbikes, it may be rigidly mounted. Force is transmitted hydraulically from the brake line through the piston in the caliper. The piston then presses both the pads against the disc, thereby squeezing it. Discs are usually vented to allow fast dissipation of the heat generated due to rubbing of pads and disc. Vehicles with disc brakes also have an emergency brake system in case of primary brake failure. In most cars, the lever pulls the cable which turns a cam or screw. The cam or screw actuates the piston in caliper, thus producing braking action. Since there can be permanent actuation without the need of driver, this is useful to park cars on slopes. Some braking systems have dedicated drums installed in the rear wheels meant only for emergency braking.

The Proper Care and Maintenance of Your Bicycle
Learning to ride a bike is no big deal. If you fall off, just brush yourself off and climb back on. Learning how to keep your bike from falling apart can be just as easy.
Bicycle maintenance is vital to the performance and preservation of your ride. Without proper maintenance, your bike will quickly go from a lean, mean, two-wheeled machine, to a squeaky, rusty, pant leg munching mess. Keeping your bicycle in top condition requires regular protective and preventive maintenance, some of which can be done by you. Other jobs may require the skills of a professional cycle repairer.
Tires
When riding a bicycle, most of the load and pressure falls directly on the tires. Check your air pressure to be sure the tires are inflated as per the manufacturer's specifications. Tires should be inspected on a regular basis for any signs of ripping, or wear and tear. Wheels need regular tuning and adjustment, and should be checked for dents and twists caused by collisions or falls. Spinning is the best way to check a wheel. If the wheel shakes from side to side as it spins, it will need to be tightened. Spokes also need to be tightened and fixed firmly to the rims as part of regular bicycle maintenance. The spokes transmit pressure, so if they're damaged they must be replaced immediately.
Handlebar
Similar to the steering wheel of a car, the handlebar is a key component in maneuvering the bicycle. A handlebar needs to be adjusted to produce the best results. Adjust the height so that you can comfortably hold the handlebar when seated. The handlebar should be properly aligned with the front wheel, to accommodate both quick swerves and smooth changes in either direction. A properly adjusted front fork is equally important. The front fork stabilizes the handlebar and should be securely fastened to the handlebar post. Also, be sure that your bicycle maintenance regime includes checking that the pedals are tightly secured.
Brakes
The single most important part of the bicycle for rider safety is the brake assembly. Check the brakes by squeezing them and rolling the bike ahead. If the brakes work properly, the wheels will not roll and the brake pads will stay squarely on the rims without touching the tires. If the brake levers touch the handlebars when pressed, it means the brake cables are loose. Tighten them and check for wear. If the brake cables are frayed, have them replaced.
Chain
Proper bicycle maintenance includes regular lubrication of the chain, to produce smooth and swift movement. Use a de-greaser to remove accumulated dirt on the grease. Remember to put fresh grease on to replace the dirty grease that has been removed. Keeping your chain clean and well lubricated will keep it from getting stuck or jumping the gear teeth.
Keeping your bicycle in prime riding condition doesn't take a lot of tools or a great deal of technical knowledge. Bicycle maintenance is a simple task that takes only a little time and effort. Keep your bike fit and it will last many years keeping you fit.

Is this a decent bike for a few hundred dollars?
Sounds like you are describing a Nashbar AT-1 Mountain Bike. It's a decent bike. Just remember there will be shipping cost and you will need to assemble the bike yourself. Or, pay a bike shop to do it for you. That's usually about $40 - $50.
Add up all the cost involved & then compare to buying one locally from your neighborhood bike shop. I bet it comes out about the same. Support your local bike shop.
