Basic operate of associate degree Automotive brake

When you progress the treadle, hydraulic fluid is forced from the hydraulic brake cylinder through the brake lines, right down to the pistons within the calipers or wheel cylinders, forcing them to expand golf shot pressure on the pads or shoes. On hydraulic brake setups the caliper piston squeezes the restraint against the rotor. On a hydraulic brake setups the wheel cylinder piston pushes the constraint against the drum inflicting the wheel to prevent. this can be simply a locality of what’s happening. The Braking system is largely associate degree instrument that changes energy. once moving your automobile has K.E. by applying the brake the K.E. is reborn into thermal (heat) energy via friction created by the pads rubbing against the rotors. The cooling of the brakes dissipates the warmth and therefore the vehicle slows down.

A typical automotive disc brake system consists of:

• Pads – The brake pads are main components of the braking system. They consist of a steel backing plate and a molder, bonded or riveted friction material puck. A typical brake set usually contains 4 pucks 2 inner and 2 outer for one front or rear axle. There are many different types of friction materials depending on the use of the vehicle.

• Rotors – Disc Brake Rotors are found on many different types of vehicles, from bicycles to airplanes and are made of many different materials. The most commonly used in road cars and trucks are made of cast iron. Cast iron is used because it absorbs and dissipated heat well, resists ware and is inexpensive compared to other metals.

• Power Booster – The Power Brake Booster amplifies the pressure applied to the brake pedal so that less foot pressure is needed to apply the brakes. There are different types Power Brake Booster the most popular are the vacuum and the hydraulic type

• Hydraulic Master Cylinder – The master cylinder is a hydraulic pump powered by your foot which converts non hydraulic pressure to hydraulic pressure to move components at the other end of the braking system. The pressure created by your foot is transferred by the master to the pistons in the caliper or wheel cylinder. The Master Cylinder is located in the engine compartment usually on driver side and also contains the brake fluid reservoir mounted on top.

• Brake Fluid – Brake fluid is formulated to withstand high temperatures without boiling and cold temperatures without thickening. Brake fluid is also designed to absorb moisture so that it won’t collect causing rust or freeze in cold weather. All brake fluids must meet standers set by the Department of Transportation.

• ABS System (optional)

• Proportioning Valve – The Proportioning valve are designed to adjust the pressure between the front and rear brakes. Usually mounted on the fire wall bellow the master cylinder. The valve directs less pressure to the rear brakes to preventing premature lockup under heavy braking.

• Calipers – The Caliper pushes the brake pads against the brake rotors when pressure is applied via steel pistons.

• Hoses and Line – The brake lines and hoses transfer brake fluid pressure from the master cylinder to the calipers or wheels cylinder. Brake lines are usually made of bent steel tubing wile standard brake hoses are made of reinforced rubber. Also available in the aftermarket are Stainless Steel Braided Performance Hoses, these houses reducing expansion which improve braking and provide a firmer pedal feel.

• Wheel and Tiers – Yes the tires are part of the braking system as they are the contact with the road. Bad tires will dramatically affect braking performance

You should have your brake checked frequently not only for safety reasons, but also to avoid costly repairs due to damaged caused by warn parts. As all vehicles are different you should check the correct schedule in your owner’s manual.

Signs that you may need brake service:

• Noise, squealing or grinding when brakes are applied.
• Stopping distance is increasing.
• Increased brake pedal travel.
• Steering wheel shakes when you apply the brakes.
• Vehicle pulls to the right or left when brakes are applied.

When your brakes or rotors need replacing, use quality, tested products designed for your vehicle. Also consider upgrading your brakes for improved stopping and reliability. SP Performance manufactures Rotors and Brake Pads that improve performance and reliability at a reasonable price.
