Brake pad contact question

[TwIzTeD_3kGt]

Yesterday I finally got around to turning my extremely warped rotors. I cleaned off all the caliper pins, lubed them, and cleaned/sprayed the back of the pads with that pad quiet stuff. Now I see two issues:

1 - The pass. rear outside pad is only making contact on about a 1/4" of the center of the rotor. The pads slide on the pins very easily, no grooves worn into the sides of the caliper where the pads touch(Driver-rear had grooves from the pads, but is contacting fine). Bad caliper? Need bleeding maybe? Related to front pads having about 90% wear?

2 - I made a hard stop from about 80 to 20, my front rotors turned redish/bluish (heat scorching). How bad/dangerous is that?

Thanks to anyone with some experience here.

I would suggest replacing your pads if they have 10% left

But if those are the fronts they shouldn't have anything to do with your rears. Wait a little while and see if the pad seats into the "unwarped" rotors better.

If you had warped rotors with the pads there is a possibility they were just wearing funny because of that.

As far as the 80 - 20 stops, I have the same problem, but I think it is because I am using crappy rotors/pads. Oreilly brand to be exact.

It is just getting very hot and its not so much "dangerous" as it can glaze your pads/rotors, so it could become a "glass on glass" braking scenario. Glass on Glass doesn't stop very well.

Basically when that happens you are probably going to experience a lot of brake fade, but as long as that is not your normal stop and you do that very rarely, you'll be ok.

What pads/rotor combination are you using?

Hope this helps!

Pretty much summed it up there. Assuming that the caliper is fully functioning, the warped rotor would most likely have caused it. Like stated above the pad/rotor combo you are using could be an issue as well. They came with ceramic rear pads from factory. A big mistake people make is thinking that they have to brake hard to break the pads in.

Not sure of what brand/quality is on there currently, it's just what was on there when I bought the car. Pretty sure they're ceramics on oem rotors though, I never have any brake dust on my rims.

But I just wanted to make sure the scorching wasn't a sign that the rotor might fail or something. I can defintely feel the brake fade though, that 80 to 20 stop didn't feel good at all. I'll be putting pads on it soon, I was just bored at work and decided to do some free maintanance. Thanks for the tips.
