As a rule of thumb, once they get to about the same thickness or less as the backing plate-time to change, since they go quickly from there. Also there are rivets inside so you can't use 100% & those rubbing on rotor/drums not good. The rotors do most the work & wear faster. Many people routinely check fronts (when cold) by just sticking your finger thru the wheel & feeling pad/plate along side.
The front pads should be 11mm and minimum 2mm. The rear pads should be 10mm and minimum 1.5mm. Use Google to convert to inches.
Look at the pads and measure the thickness. The minimum allowed thickness for the brakes pads is 2 mm. Replace if they are worn to this point. You will have to remove the wheel to measure the pads.
Just buy new brake pads.
Brake pads should be replaced at 3/32".
Not unless they are under the minimum thickness spec.
The brake pads have a small metal piece which makes he brake squeak. This means it's time to change your brakes. The longer you let it squeak, the more damage it does to you rotor. Still the rotor can be resurfaced or if needed replaced.
There is a legal minimum thickness for all rotors.
Volvo brake pads do not have squeaking tabs on them except for the 2000-2004 S40. Regular inspection intervals are required to visually determine brake pads remaining thickness. Volvo recommends replacing the pads when there are only 2mm remaining. Once the pads wear completely away and start rubbing metal to metal the rotors must be replaced. Rotors have two minimum thicknesses also. One minimum is Pad Change Min which is the thickness usually about 0.8mm above absolute Min Thickness where the rotors will probably not be below the absolute minimum by the time the pads wear out. The absolute minimum thickness is usually stamped on the hub of the rotor and varies with the diameter of the rotors. Your local dealer can tell you what the thickness specifications are for your particular vehicle.
It is the thickness of brake pads when they are new form factory.
later models of the hyundai accent had a minimum brake pad thickess of around 200mm (20cm) the reason being was the fact that the disc was paper thin, so they compensated for the wafer thin disc by oversizing the pads
Yes, if you measure the rotor thickness, they will be under minimum spec.
Yes it has front brake pads.
