Front Disc Pads....question

[BHerring]

Hey all,

First I have a 1993 Dodge D-250 2WD, regular cab. I replaced my front pads with some aftermarket ones and I took off the front wheels to inspect everything (approx 3 weeks after install) anyways I noticed the outside of the rotor (the rotor facing you when you take the tire off) had no wear on the bottom 1/2". Meaning the pads are NOT touching the rotor 1/2" from the bottom. Does this make sence? The back of the rotor the whole pad touches the rotor. So I decided that I may have purchased the wrong pads so I ordred some pads from EGR part number 086 and there pads are the exact dimensions of the after market.



So is this normal to have 1/2" of unused rotor on the outisde on both tires and 100% rotor use on the inside.



Attached are some pics to make it easier to understand.



Any comments will be greatly appreicated.



Cheers

How do things line up when it's all together? I have noticed that on the outside, not all the rotor sees pad contact. My W350 has about 1/4" not contacted by the pad. The rotor in the shed has what you'd expect- about 1/8" or less where the pad didnt contact the rotor. I think it has to do with what the aftermarket companies are putting on there for amount of friction material- every little bit they can reduce cuts costs.

DP,
Everything lines up just perfect and yes the outside rotor has 1/2" no pad contact. I have 2 different makes of pads, the local auto store pads and brand new pad (very costly pads I might add) from EGR and they are both the same dimensions. The inside rotor/pads are getting 100% contact. To me the outside should also be 100% or let me say less than 1/2".

Yes, it's normal. Look at the inside of the rotor, there is no extension of the braking surface or obstruction beyond the inner area of the rotor that would interfere with the location of the caliper. On the outer side of the rotor the braking surface has been machined beyond the area used by the pads so as not to interfere with the mounting of the caliper. bg

Thanks, time to put the beast back together
