Typical Problems of Automotive Disc Brake Rotors

The Disc Brake Rotors are a main component of your vehicles Braking System. The Rotors are a wearying item, and should be schedule checked to assure proper condition before a problems may arise.

Rotors are found on all different types of road and off road vehicles. Brake rotors can be found on bicycles, motorcycles, cars, trucks, trains and airplanes. Rotors are constructed of many different materials, most commonly made of cast iron. Cast iron is preferred because it absorbs and dissipated heat well, resists ware and is inexpensive compared to other metals.

Function

When you push on the brake pedal the caliper squeezes the brake pads against the rotors. A small amount of brake pad friction material is transferred from the pads to the rotors; helping the rotor and pads to stick providing friction. The friction created converts Kinetic Energy to Heat Energy. The Rotors dissipation of this heat is what causes the vehicle to slow down and Stop. The material transfer is why it is important to break in the pads and rotors. If the pads are not properly broken in, they may leave an uneven deposit of friction material on the rotor surface resulting in a high runout, Disc Thickness Variation or other problems.

Brake Rotor Problems

Rotor Runout: A measure to determining whether the rotor axis is parallel to the spindle axes. If the runout is too high it will result in a high and low point on the rotor contacting the brake pads causing pulsation in the brake pedal under braking. The runout can also occur if the rotor is unevenly warn and is thicker and thinner in different locations on the brake contact surface called Disc Thickness Variation (DTV).

Note: It is important to check runout when doing a brake job, especially when installing new rotors.

Runout tolerance: Tolerances can vary for different vehicle. Some vehicles are more sensitive to runout than others. Commonly lighter vehicles with lighter suspension are more sensitive and require smaller runout. Also a warn brake, suspension and steering components will also amplified the vibration form the rotor runout. To measure runout a dial indicator is needed. The dial is placed on the face of the rotor, the rotors is turned slowly while reading the dial autointhebox coupon code. If the runout exceeds factory specification it will need to be correcting to avoid vibrations.

Note: When installing new rotors in many cases runout can be corrected by removing the rotor and repositioning it on the hub, make sure that the rotor and hub mounting surfaces are clean, clean, clean. If repositioning the rotor dose not reduces the runout, it can be corrected by placing shims in between the rotor and the hub. Shims of different thicknesses are available to correct the runout.

Runout can occur due to:

¢ On even brake friction build up.

¢ Improperly torque wheel lugs.

¢ Bad resurfacing.

¢ Rust build up in between the rotor and hub.

¢ Rotor Warping.

¢ Warn wheel bearing.

Rotor Warping and Pulsation: The words warped rotors are the most commonly used to describe Brake pulsation and vibration problems. But this is incorrect rotors don't actually warp. Brake vibrations and pulsation are caused by Brake Torque Variation (BTV) and Disc Thickness Variation (DTV) individually or in combination.

Brake Torque Variation: (BTV) is a variation of torque across face of the rotors braking surface. This variation cassis the brake pad to slip and catch as the rotor rotates. BTV is usually cased by uneven deposits of brake pad material on the rotor surface or by hard spots usually do to the metallurgy of the brake rotors. The torque variation will case vehicle to vibrate or judder and may or may not be felt in the pedal.

Disc Thickness Variation: (DTV) is the defense in thickness at multiple spots around the rotor's braking surface. This variation in thickness increases runout and causes the rotor to push the Caliper Piston in and out maxisys elite. This movement crates vibrations and pulsation that are transferred trough the brake pedal and the chassis.

Two Cars That Offer the Best Value For City Living

Unless you have a specific use for your car, for example if you are a landscaper and need your vehicle to be able to move heavy equipment day in and day out, the majority of city dwellers are looking for a small midsize or compact car that can zip them through the busy streets of downtown living Autel Diaglink, with style and fuel efficiency.

Here are the two best (and stylish) cars to bring your from your 9-5 job to your uptown apartment, and back down for dinner with friends, on less than a quarter tank of gas.

Best Compact Car: 2014 Ford Focus

Put simply, the Focus feels like a step above the rest. Even in the lowest trims the cabin utilizes higher-quality materials, the efficient engine is energetic and the driving experience strikes a near-perfect balance of involvement and comfort. Whether you want a compact car that's fun to drive or just quiet and comfy transportation, the Focus will meet your needs.

As the trim levels and options swell with high-end features like heated leather seats, it becomes shocking that anyone would opt for pricier luxury compacts like the Acura ILX or Buick Verano, plus, the Focus excellence also carries forth to its other variants, including the Focus Electric and sport-tunes Focus ST. When each went on sale they leapfrogged their respective competition. Any other compact car would have to make a pretty significant leapfrog of its own to outdo the Focus.

Best Midsize Car: Hyundai Sonata

The 2013 Hyundai Sonata remains competitive in its class, thanks to modern styling, high fuel economy estimates and a spacious cabin.

The 2013 Sonata has a four- and turbo-four-cylinder engine, and critics say both engines offer plenty of power for most drivers. Both engines have good fuel economy ratings of 24/35 (base) and 22/34 (turbo) mpg city/highway for the class.

Overall, the layout, design and functionality the Sonata's cabin provides a comfortable ride and feeling. There's plenty of space for families, and many test drivers like the stylish, contemporary interior design. Reviewers say the 2013 Hyundai Sonata has a good array of standard interior features for the class, including Bluetooth, auxiliary and USB audio jacks, satellite radio and Hyundai's Blue Link telematics system. The Sonata can be equipped with features like a rearview camera, heated front and rear seats, a panoramic sunroof, Infinity sound system, HD Radio and navigation.

The Ford Focus and Hyundai Sonata meet the top requirementsof the average big city dweller - they are small, quick and great on fuel. They are also very affordable with many options such as: sunroof, touch screen radio and on board GPS.

Although these cars may not be the head-turning, luxury Porches or Bentleys you see parked outside the hottest restaurants and clubs downtown, they are certainly better on fuel, great for everyday city living and will give you the biggest bang for your buck.
