The Working of a Hydraulic Braking System

Filed under: 2014 — Tags: — Ralph C Dreher @ 7:17 AM

A hydraulic brake system is one that uses brake fluid to transfer pressure to the wheels. In this system, when the brake pedal is pressed, force is exerted on the push rod, which in turn pressurizes the brake fluid, which pushes the pads against the rotor disc to stop the vehicle. A hydraulic braking system has the following parts.

  • Master cylinder
    This consists of a cylinder filled with brake fluid, a brake fluid reservoir, one or two pistons, ports from the main cylinder to the brake fluid reservoir and a return spring. The master cylinder receives pressure from the brake lever and conveys it to the hydraulic lines that start from it.
  • Wheel cylinder
    Similar to the master cylinder, the wheel cylinder receives pressure from the brake fluid and pushes the brake caliper pistons against the disc.
  • Brake fluid (or brake oil) pipelines
    These pipelines carry the brake fluid and connect the master cylinder to the wheels cylinder in each wheel.
  • Caliper assembly
    The caliper assembly contains the brake caliper pistons and the rotor disc. The caliper assembly is the component which is actually involved in the process of slowing down the wheel.

Working
When the brake pedal is pressed, the push rod presses the master cylinder’s piston. The piston pressurizes the brake fluid in the cylinder. The fluid moves through the pipelines and reaches the caliper assembly. At the caliper assembly, there are two pistons one on each side of the rotor disc and they are connected to the brake fluid. The brake fluid pressurizes each of the pistons from both the sides, and pushes them towards the rotor disc. Since there is a one way movement of the brake fluid due to the pressure from the brake lever, it is displaced in the brake fluid reservoir. This process leads to a frictional motion between the brake calipers and the rotor disc, and thus braking happens. And when the brake lever is released, the return spring in the master cylinder pushes the master piston to its original position and the displaced brake fluid returns back to the pipelines.

Brake fade
Brake fading is a common disadvantage of the hydraulic braking system. It is caused due to the following reasons:

  • When hydraulic brakes are subjected to heavy work like descending down a steep inclination, they produce a lot of heat. This might, in extreme conditions, vaporize the braking fluid. This causes ineffective or weak pressure in the caliper assembly and thus faded braking.
  • Due to continuous usage, the pads which cause friction over the rotor disc may become soft due to wearing. This also causes ineffective braking. It thus becomes important to check the brake pads regularly, and if necessary, replace it.

All That Businesses Need to Know About Inbound Marketing

Filed under: 2014 — Tags: — Ralph C Dreher @ 3:13 AM

Inbound marketing deals with attracting warm leads (potential to turn into sales) in contrast to outbound marketing which deals with cold leads. It mainly uses interesting content to acquire customers. Inbound marketing will be advantageous to companies that have tight marketing budgets. It offers a unique combination of more efficiency at a relatively less expenditure.

Inbound marketing comprises various activities like search engine optimization (SEO), content marketing, blogging and social media marketing. SEO deals with working out on your website so that you get better rankings in search results, which is likely to increase online visibility. Content marketing involves various activities like creating useful and unique content, providing articles, white papers, blogs etc. Content is used as a sales pitch to a certain extent by providing value to customers.

Process of inbound marketing
There are different stages in inbound marketing which help in giving a structure to your marketing activities. It involves four to five stages. The first stage is to design a strategy that attracts website traffic, the second is to convert website visitors into leads, the third is to convert leads into sales and the final stage is to measure the results and accordingly redesign the strategy or take corrective actions.

Advantages of inbound marketing
Cost effective
Inbound marketing is completely done online, which offers many chances to reduce your marketing costs. In traditional marketing, targeting specific customers is difficult. But in inbound marketing you can easily target a specific section of customers, so you will spend only on those online users who are more likely to become your customers. As you do not depend on mass media for your marketing activities inbound marketing saves a considerable amount.

Availability of measurement tools
Another most likely advantage of inbound marketing is that you can easily measure the effectiveness of marketing campaign. This means, you can get a clear picture on return on investment. You can measure change in the traffic to your website using analytical tools. Doing these measurements and analysis will help in knowing which marketing activities are working and which are not. This will help in designing new strategies which will further improve the effectiveness and efficiency of your marketing activities.

Interactive communication
With the help of articles, you will be able to attract online users to your website. Once the users feel that the information is helpful they start interacting with you by posting comments, sending mails, etc. When the communication becomes interactive, it is likely to lead to customer engagement which is important to make customers interested in your products. You can also use social media to communicate with customers as they get a chance to directly interact with you. This helps in building good relationships with your customers which is very important in any business.

Value to customers through rich content
The rich information you provide through inbound marketing not just prompts customers to buy your products, but gives them valuable information they are looking for and thus adds value to your service. You provide value to customers and in turn you get benefits in the form of quality leads. By providing good content, you can show your expertise which could make your customers trust you as an expert in your niche.

These advantages show the importance of inbound marketing that not only helps businesses reduce their marketing budgets but provides effective results when implemented properly.
