What is the importance of changing brake pads and when do they require a change?
Braking is a very important aspect of driving and unlike most other variables like power and dynamics, good brakes are absolute life-savers. While most modern cars and motorcycles are equipped with disc brakes at the front end, some even have them deployed at the rear. A disc brake system makes use of brake pads to press against the rotors when the brakes are applied. It is the brake pad which provides friction by rubbing against the brake rotor to slow down a vehicle. Let us talk about the symptoms which indicate that the brake pads need replacement –
5) Visual Inspection – In most instances, a close look at the brake pad from outside is enough to judge if the brake pads have enough thickness. Ideally, a brake pad with 2 mm thickness is considered at the end of its life.
4) Noise From Brakes – Worn out brake pads can cause grinding noises while applying brakes. This happens when the worn out surface of the pads grinds with the metal surface of the rotors.
3) Braking Force – As the brake pads wear out, there is a gradual loss of braking force. For those who drive on a regular basis, it is easier to detect and diagnose such drop in braking efficiency.
2) Dashboard Warning Lights – Several modern automobiles are equipped with sensors that detect worn out brake pads. The system throws out warnings in the form of lights or icons or on-screen messages.
1) Brake Pedal – Mild vibrations on the brake pedal during braking point towards worn out brake pads. Change in brake pedal play and feel means that the braking system needs attention.
Wearing out of brake pads depends on various factors and there is no set interval for the change. As a part of service, brake fluid used in hydraulic brake systems needs to be replaced every 2 years or 20,000 kms. Brake bleeding, a routine part of brake service, is performed to get rid of air bubbles from the brake lines. Below are the advantages of changing brake pads on time –
5) Stopping Power – Brake pads provide friction on the rotors which translates to stopping power of a vehicle. A shorter braking distance can help one avoid accidents by stopping the vehicle in time.
4) Improves Life Of Brake Components – Changing brake pads on time prevents stress or damage on other brake components. It greatly improves the life of rotors.
3) Prevents Damage To Brake Components – Worn out brake pads can damage brake rotors by scratching their surface. Replacing disc rotors is a costly affair.
2) Prevents Major Expenses – Undergoing minor expenses like brake pad replacement from time to time can save one from the hassles and high cost of replacing an entire braking system before time.
1) Safe And Confident Driving – A properly functioning braking system multiplies the confidence of the person behind the wheel. It also makes driving safer and more predictable.
