Maintaining Pressure in Tyres of Your Car

by Edwin Rosenthal

Tyre care adds to the safety of the vehicle. Tyres should be checked before going on long drives and also at regular intervals. Tyre pressure maintained correctly in both will improve efficiency, fuel, safety of vehicle and extend life of tyres. Mostly tyres are neglected parts in a car.

Once a week check for pressure in tyres
Tyres leak and they need to be checked at regular intervals. Maintain the right amount of pressure in tyres to avoid poor mileage, tyre getting blown out or wearing of tyre. Poor tyre pressure affects the comfort level and handling or steering of car. Check for tyre pressure once a week and get them inflated as mentioned in owner’s manual.

Check for tyre pressure once a week. Rotate your tyres for every 5,000 miles to 7,500 miles to distribute wearing of tyre evenly in order to ensure longer road life. Your owner’s manual will mention the pattern and period of rotation you need to undertake else ask your car dealer.

Fill air in your car tyres for every 5,000 miles or 8,000 km
Under – inflation or over – inflation of tyres can damage your car. Fill air in tyres for every 5,000 miles or 8,000 km. Under-inflated tyres will expand and bulge putting more pressure on the sidewalls of the tyre resulting in poor driving performance. If you stay in a place where the temperature changes a lot, fill air in your tyres as and when required.

Check for tyre pressure during weather changes
When the weather changes, tyres are adversely affected. Tyre pressure changes during rise or soar in temperatures. As weather changes, you need to do regular maintenance once a year or twice a year. It is better if we check the tyre pressure for every two months or during extreme changes in weather. If you experience vibrations while steering then the tyres need to inflated. When there is rise in temperature the tyres can blow out.

Check for proper alignment of wheels
Wheel alignment should be checked for every 30,000 miles or as recommended in owner’s manual.
If tyres are not aligned properly, it will shorten the life of tyres and there will be problem in your steering too. An over-inflated, under-inflated, worn-out or not properly aligned tyre can be very dangerous especially during hot summer days. If your tyres are inflated properly, uneven wear shows the improper alignment of wheels.

Tyre depth should be maintained
The tyres should have a minimum of 1.6 mm of tread depth. Always keep a spare tyre with you in car. See that the spare tyre is properly inflated and has sufficient tread depth. Replace your tyres if your tread depth is low.

Solving Your Car’s Brake Squeal

by Edwin Rosenthal

When the brake pad against the caliper piston is not properly fit, the friction material has a problem, or gone, the brakes will squeal. The squealing is the result of high frequency vibration among the brake rotor, the caliper piston and the pad in either of the cases. Some vehicles come with the squeal problems directly from the manufacturer or factory. In these cases manufacturer simply change the brake pad to cure the problem. Because there are different harmonic frequencies for different pads.

  • Steps to solve brake squeal: If your brakes are squealing follow these steps.
  • Check for loose parts: Try to move slightly the calipers, brake pad and other components of the brake. They should not move only just with your hands, because loose parts can vibrate and it results in noise.
  • Replacement of parts: Make sure that in the caliper assembly, the pad does not move. If you find any missing, damaged, and clips or shims are loose replace them.
  • Apply dampening paste: Apply thin layer of the dampening paste between the caliper assembly and the pad. It creates a thin shock absorber to dampen the vibration and the sound. Give plenty of time two to three hours of time if you can, for paste to dry before assemble the brakes. When it is dry, it will become darker color and sticky. If you kept it under the direct sun or used a hair dryer to dry the paste more quicker, wait until the temperature is come down to room temperature.
  • Check brake pads: Sometimes the brake pads will wear. Therefore, check for them if they are worn, replace them. Most of the disc brakes have a wear indicator. If the pad is worn up to a certain point, the indicator makes noise. Check the manual or material for suitable brake pads for your vehicle.
  • Organic pad: It can be with or without asbestos. It may not wear resistance of metallic or semi-metallic, may lack of performance and it may quieter. It may not tolerate the heat as much as other pad materials so because more brake fade.
  • Semi-metallic pad: It has organic material and metal particles. It is the best in both less noise and braking ability in the world. It may wear the rotors. It decreases the brake fade and increases the life of the pad. It can also tolerate the repeated hard stopping.
  • Metallic pad: To provide most friction against rotor, different metals are used. At high speeds with minimum wear, it works great for repeated stopping. In the stock rotors, which are not designed for use with metal pads, rotor will wear faster when metallic pads are used.
  • Lubricant materials: Carbon, Graphite, Brass and some other materials can help to reduce the noise, so look at the formula, which is for built into brake pads.
  • Check brake rotor: Check the drum or rotor for grooving, scoring or other wear.
  • If the entire rotor is distorted or warped or wear is excessive, you need to replace the rotors. If the sound is like metallic grind and not squeal, you need to change the rotors. read more »

    Car Brakes Malfunctioning And Maintenance

    by Dov Waxman

    Brakes are the most essential safety constituent of a car. It is mandatory to keep brakes of car in best condition in order to have security. Many brake problems are generated gradually and these can be identified properly in system before they become serious.

    There are many causes for breaks malfunctioning.  Few of them are:

    • If the brakes screech or sound when they are pressed, it can be either the brake pads need to be  changed or the brakes should be cleaned.
    • A soft or slushy brake pedal signifies that the amount of brake fluid is low.
    • When the rear brake lining is corroded, the brake pedal becomes completely down.
    • At times the brakes may pull the car completely to one side. This indicates that brake clearance should be adjusted or there might be lack of enough hydraulic pressure in specific part of the brake system.
    • If the amount of brake fluid level is less, the system displays it by glittering the brake light.  In this case brake fluid should be filled immediately.

    Hand Brakes: Hand breaks must be applied only after the clutch is pressed or when the car is on the neutral. This will not spoil the clutch system. When general check up of brake system is done, notches of the hand brake must be checked thoroughly. If the brakes are not effective, then the cable must be replaced.

    Level of Brake Fluid: The low level of fluid in brake fluid container might be due to leaks in the brake system. So, this problem must be immediately examined, because driving a car with less amount brake fluid level is dangerous.
