minimum thickness of brake rotors

[zskinner]

so ive always had squeaky brakes but in the past few weeks it has gotten alot worse so i decided to check out all my rotors and pads. everything seemed good except my front rotors which i wasnt sure about. i measured the thickness and i got 23mm on the left side and 22mm on the right side. should i be replacing these soon or should there still be some life left in them? thanks for any input p.s. its a vp v6 auto without irs or abs or anything fancy lol

sweet as thanks heaps mate . any chance does anyone know how long front rotors should last? ive had these on for about 40,000 kms and i do a fair bit of city driving in stop-start traffic, is that any good or should i be expecting better? cheers

it will depend on how much of a later/hard braker you are, city driving in a auto you are on and off the brakes flat out and if the rotors are a cheap set they wont last long, hard brake pad material on a soft metal rotor will kill a set of rotors very quick

cheers mate, yer they were a fairly cheap set so i think im pretty happy with how long they've lasted

Just use soft pads, my rotors have some wear as well but used to squeak and make all sorts of noises with hard pads.
