So I went to the Ford Dealership for an oil change/tire rotation on my 2006 Ranger. The guy there todl me that I need new front brakes. I just had them replaces brand new about a year ago. He said I have 20% on them, abot 3mm. Now, I know that dealerships always lie and BS you and try to get you to get new stuff. But should I realpace them? How much is 20%? I think I have a little more meat on them than 20%. They aren't squeaking or having any trouble coming to a stop.
Thanks
When you replaced them a year ago, did you just replace the pads and turn the rotors, or did you replace both the pads and the rotors? I would find hard to believe that all new pads and rotors would be worn to 20% in a year unless you are especially hard on your brakes. If you only replaced the pads and turned the rotors, it's more reasonable that they would be that low after a year.
The 3mm measurement is refering to rotor thickness. The stock rotor is .39 inches, which is 9.906 millimeters. That would put you at about 30% life remaining on the rotor. Most replacement spec guidelines call for replacement at 15%-20% which would be about 1.5mm - 2.0mm. In this case I think they are being a little proactive in recommending changing it now, but you probably only have about 10%-15% recommended life left in them. You can probably put it off till the next oil change.

I believe you're confused.
The minimum rotor thickness (discard) is ".964 or 24.5mm and the machine to (to last at least as long as new pads) thickness is ".980 or 25.1mm.
I'd say the 3mm or 20% refers to the pad thickness remaining. If so, then it's time for new pads.
To the OP;
If you really do only have 20% pad left, they're not lying to you. They're doing you a favor. If they wear much more you'll could be buying new rotors.
Yeah Goat yer a tad confused this time... Even my bikes have thicker rotors that 3mm's.
To the OP I would want to be shown if I wasn't familar. If the rotors are all beat up nasty scored, worn thin, that can tear up pads. If the system hasn't been bled in the last 2 years then the caliper pistons may be sticking, so the brakes are partly ON when you don't want them ON.
That will tear up pads real fast. The brake fluid might look great in the master cylinder on the fire wall, but be total junk black mung in the calipers.
no its normal to swap them out after a year. after i got myself a camry automatic , i noticed the same. you brake probably double as much with a automatic than a manual gear. the other cars i have i only change every 2.nd year.
