How to Maintain Braking System of Your Car?

Automobiles are all interconnected parts in a system but we should maintain it to keep it running efficiently and smoothly. The braking system is an active and important component of your car. If your car doesn’t have a good braking system, you and your co-passengers are likely to be in danger. A braking system is a combination of mechanical, electronic and hydraulically activated components, which uses heat or friction to stop a moving vehicle.

A poor braking system in a car is danger to the passengers inside the car
Poor braking performance is given by worn out brakes. The brakes when applied in a car will resist the the movement of the tyres by friction, and the tyres will come to null motion. Check the power of braking of all the four wheels with a brake meter or brake tester. Rust formed on brake linings can cause the braking system to fail. In order to avoid these inspect the linings regularly.

To stop a car, the braking system should be maintained properly
You are allowed to stop your car by pressing the brakes inside, therefore maintenance of brakes are very important. Get your brakes checked annually by a professional and know the signs of wear like delay in response while pushing the brake pedal and your car showing brake lights on the dashboard or making loud sounds. In case of a brake failure, use parking brake or change to lower gear and turn off the engine.

Vibrations in brakes must be taken care of
Grinding on rotors or unusual vibrations in brakes is indicative of a poor braking system and it needs replacement as soon as possible. If there is squealing noise emitted. it is a warning that your brakes are worn out and need replacement. Overheated brake pads and rotors sometimes get rusted and form a lining on the brakes thereby causing squeaking sound.

Use brake fluid for your car
The brake fluid in your car must be full. Use brake fluid mentioned in owner’s manual for your vehicle. Check the level of brake fluid in the reservoir, if it’s low then top off with correct brake fluid. When the brakes fail in your car then it means that the brake fluid has gone down.

If there is a steep decrease in brake fluid level, it might be due to leakage or any other issue in the braking system. If there is a leakage of brake fluid, the brake’s master cylinder will allow air into the system by creating low pedaling and finally results in failure of braking system. Replace the brake fluid after every two years or 50,000 miles, whichever is earlier.

Know about Anti-Lock Braking System

An anti-lock braking system (ABS) is a automobile safety system that lets the motor vehicle wheels continue interacting with the road surface as directed by steering inputs given by driver, and while braking, preventing the wheels from locking up. In other words, it is a technology designed to help the driver to maintain some steering ability and avoid skidding or slipping while braking.

The anti-lock braking system was introduced in the mid 1980’s and has become standard equipment on the majority of the four wheeler vehicles such as cars, trucks and multipurpose vehicles. This helps maintain directional stability and helps you steer while maximizing braking.

The primary function of the ABS is to prevent the wheels getting locked up. This is possible by modulating automatically brake pressure in the event of an emergency. Preventing the wheels from locking helps you maintain control over steering and to stop the vehicle in the shortest possible distances under most conditions.

In emergency situations, you can sense the pulsation in the brake pedal during ABS operation and is indicated by a fall and rise height of brake pedal and a clicking sound. ABS system consists of some following components:

  • Speed sensors.
  • Brake calipers.
  • A hydraulic motor.
  • Anti-lock brake control module.
  • Hydraulic control module.

Sensors calculates the speed of the vehicle and the difference of the rotational speeds of the braked wheels and this information is converted into electrical signals. If a wheel gets locked up, the hydraulic valves reduce the effect of brake on that wheel. This prevents skidding and allows you to maintain steering control. Read the rest of this entry »
