How do you know if you brakes have worn out
 

Well i opened the hood recently and noticed that the brake oil bottle has level somewhere in between the minimum and maximum level.

The second thing i realized while driving was that when i applied the brake too hard the abs was activate and made a lot of noise but the car just went on going a bit.

So do i need new brake pads. Is there anyway to measure brake wear. I am from pakistan and we don't have mazda dealership here.

take the wheels off and view the pads through the back of the calipers . There should be a minimum of 3mm (approx.) of pad material . Any less than that and you need new pads .

once you know what you are looking at you can tell without taking wheels off .

When you can stop yourself from double-posting! :)

I don't know if this applies to all cars but the rule of thumb that I got from somebody in my car club is that the friction material should be thicker than the backing plate.

So does the decreased level of brake oil mean anything or not.

It's not an accurate indicator of anything other then if you have enough brake fluid in the system.

if youre between the minimum and maximum... youre fine...
if you go below the minimum, add some
if you go above the max, take some away

Hussain: do you ever use the search button or just keep making new threads for every question you have???

you can also tell by your brake fluid...if its low or dirty, usually means you need new ones
