What do the numbers on the back of brake pads mean?
The numbers represent the amount of life left on the brake pads. But they’re just estimates, made by a mechanic who uses his eyeballs, not the Hubble Space Telescope. So a 5 means the mechanic estimates you’ve got about 50 percent of the pads’ life left. In which case, there’s no need to replace them.
What do brake measurements mean?
Brake pad thickness is simply a measure of the thickness of your brake pad. More accurately, it’s a measure of the thickness of the materials that make up your brake pad. These materials typically include: Friction material. Rubberized coating.
How do you check brake level?
To check the life of the brake pad, you need to determine its thickness. You might need a flashlight to get a good look at the brake pad. If the pads look thin, less than 1/4″, it might be time to get them replaced. On some brake pads, you might see a wear indicator slot down the center of the pad.

How many sets of brakes does a car have?
Most modern motor vehicles have two sets of brakes, front brakes and rear brakes. Even two wheeled vehicles such as Mountain Bikes and Motorcycles have rear brakes and these have a very specific purpose which we explain as follows.
When do you need to use rear brakes?
The first thing rear brakes will provide a back up in case of a failure of the front brakes. Not only that in modern brake systems it is quite normal for the rear brakes of an vehicle, whether two wheels or four to rely on the rear brakes for 20-30% of the vehicle stopping effort.
Which is the right side of the brake lever?
In “coaster-brake countries,” the handlebars were still empty, so the brake lever for the front brake went on the right side (below). When racers started using rim brakes on both wheels, the extra brake lever (for the rear wheel) went on the left side.

When to change the brakes in your car?
Change the Brakes Now Brake change recommendations vary by vehicle. Some mechanics recommend a rule of thumb of 25 percent brake life remaining. Forty percent brake pad availability is well above what is required for normal brake change.
When to check brake pads for wear level?
When the brake pad linings reach the 3 millimeter thickness, only around 25% of pad life remains. When checking brake pads for wear level, it should be remembered that there are pads both outside and inside the rotors, and so both will need to be checked to get an accurate wear measurement.
What is an acceptable front and rear brake lining thickness?
An acceptable front or rear brake lining thickness is anywhere between the standard 12 millimeter thickness when the break pads are new and 3 millimeter thickness after they become worn. At 3 millimeters, the sensors get exposed and make contact with the disc or rotor, creating a squealing sound.
