The “Check Brake Pad Wear” message is a reminder to have the brake pads inspected and replaced if necessary. The message will appear on the dashboard of the vehicle when the brake pads have worn down to a certain point.
A Brake wear indicator is used to warn the user and/or owner of a vehicle that the brake pad is in need of replacement. The main area of use for this is on motor vehicles with more than three wheels.
An amber brake page monitoring warning light means that action is required. This warning lamp signifies that the brake pads are worn. Please contact an authorised repairer.
The brake pad comes in contact with more flat spots of the rotor, which consequently causes the brake pad to wear out faster and more unevenly than the rest of the pads in your car. This condition can also arise from a sticking brake caliper, rust, corrosion, and frequent slamming on the brake.
Any brake system problem has to be regarded as a major safety issue and your car should not be driven until the problem has been resolved by a mechanic.
On some brake pads, you might see a wear indicator slot down the center of the pad. If the slot is gone or just barely visible, it`s time for new brake pads. Besides being visible, the wear indicator can also trigger other warnings.

This simply means a sensor has detected your brake pads are too thin. This warning light should come on before the brake pads become a hazard so you have time to get them changed.
Ideally, your brake pads should be thicker than 6.4 mm (¼ inches) for proper functioning. If it`s thinner than this, consider getting a replacement soon. Most car mechanics also agree that the bare minimum brake pad thickness is 3.2 mm (⅛ inches).
As brake pad wear sensors are designed to break, they should be replaced as a matter of course every time new brake pads are fitted. It`s also advisable to regularly inspect the sensors, in between pad changes, and replace where necessary.
The easiest way to check for a brake line leak is by holding a flashlight under your car. If you notice drips on the inside of your wheels, rust spots along the lines, or any wet or dry fluid streaks, you could be dealing with a brake line leak.
If your brake service warning light is always on, it could be due to a need for parking brake adjustment, worn brake pads, or hydraulic issues. If your brake service warning light turns on when you hit the pedal, it could be due to hydraulic loss on one side of your vehicle or low brake fluid in the master cylinder.
To test the brakes at the start of a journey, press the footbrake as you move off. They should feel sharp and not pull to one side. If they feel `spongy` or are slow to react, get them checked out by a professional.
The simplest (and oldest) light on your dashboard – the one most people refer to when they mention a brake system warning light – is the BRAKE light. When this light comes on, it means one of two things. Either the hydraulic fluid (brake fluid) in the master cylinder is low, or the parking brake is engaged.
Conservatively speaking, if you are a really hard driver, you could expect up to 800 to 1000 kilometers more from your brake pads. If you are a gentle driver, up to 2000 kms quite easily, before they damage the brake discs. What will happen if you ignore the warning light and hope it goes away?
The ABS warning light is an icon on a vehicle`s dashboard that alerts the driver to a potential problem with the ABS (Anti-lock Braking System). The ABS on a car, truck, or SUV prevents the wheels from locking up when a driver slams on the brake pedal in an emergency situation or on a wet or slippery surface.
Typically, 4mm of brake pad is recommended, so if you think they`re thinner than that, it`s time to get them checked and possibly replaced. This is the easiest way to keep on top of your brake pad condition and requires no tools or training to carry out.
Don`t be afraid to ask questions
We`ll usually recommend brake pads at 2 or 3mm. However, we`re never going to say that the brakes aren`t safe, or you shouldn`t drive, or any other scary stuff. If you ask if you can wait a month or two, the answer is yes, you`ll likely be fine.
A: New brakes pads are generally about 10-12 millimeters thick. At 3 millimeters the brakes are just about worn out and should be replaced. Replacing the front and rear brakes at the same time may save a little money and, certainly, your time without a car.
As brake pad wear sensors are designed to break or complete a circuit by contacting the brake rotor, they aren`t a reusable item. Brake pad wear sensors should be replaced with every brake pad change.
If the pads look thin, less than 4 millimeters, or there`s only 20% pad life left, it`s time to get them replaced. On some brake pads, you might see a metal wear indicator tab down the side of the pad. If the tab is almost touching the rotor, or it`s broken off t`s time for new brake pads.
At your rate it will take 33/7 or about another 5K miles to wear another 1mm.
A dragging brake shoe on the drum can lead to reduced performance in all aspects- acceleration, cruising and braking.
The most common way that brake lines fail is that they begin to leak. They are usually made of steel and capable of withstanding pressures. However, they can sometimes become worn or damaged as the vehicle is driven and are susceptible to leaks.
