I agree, that totally worn pad is likely an indication you have a stuck caliper slide pin(s). Take the caliper off, pull the pins completely out so they are not part of the caliper. That's how you can see if these slide pins are greased, loose and free. At least one pin has a rubber collar that can cause binding if swollen or if the rubber has moved on the pin shaft or the grease is gone. You can do this yourself unless the pins are totally frozen and you can't get it out.

Your wear is still unaccectable and severe, but that one pad is totally gone for another reason, like the pins.

 

i dont believe that to be the issue with mine. I thoroughly inspected everything the last time i changed pads.

 

^ we're refering to Gdawg522's pics... you just need some Cobalts

 

yeah i wasn't sure

I'm calling Cobalt today

edit: wow, i must not have looked at gdawgz's pics very closely. Yes, there is definitely something wrong going on there.

 

I'm planning on doing just that before my next event. Is there a special type of grease that will need to be put on those pins? I will be fitting the Hawk HT-12s and HT-10s this weekend. I will let you all know my initial impressions. Hopefully I can get rid of all the old, crappy Racing Brake deposits on the rotors. The Hawks were only $250 for front and rear. Hopefully they have better wear. Stay tuned.

 

Someone else on here posted that some brake compounds have a destructive effect on new pads when changing brands. This is absolutely correct, when we changed pads on our 8, I had the tech lightly turn the rotors before installing the new pads to remove any of the former pads material. The misses has a very light foot when braking and I believe she has gone thru 5 track days with the same pads, those days are usually 80 to 100 miles a session. The pads are a little over half gone now.
The boss is no slouch goin around the track either, JantzenRX8 knows who I'm talking about.

 

I use the high temp one of these... They sell little packets of it at PepBoys

 

You use them on the clips right ?

I put some other grease on the clips of my FC, but never with these stuff, guess Im ok right ?

 

I use the Ceramic Extreme on everything.... caliper pins, the pad clips, and the backs of the pads/shims as described in the service manual. The service manual separated it out to use rubber grease on some, and brake grease on other things, but this stuff can do both.

description as "other grease" nycgps, isn't enough info to comment on whether it is ok or not

 

What area of the clip did you put the goop on?

 

Ok, well the clip clips on to the caliper - no grease needed. Then take a Qtip and dab a SMALL bit o'grease inside the clip where the pad's positioning tabs will fit and (!) slide back and forth, being careful not to get any on (near) the rotor.

BTW when I did this a bit ago I put way too much grease on the pad/shim surfaces and it ooozzzed out and I had to clean up all the overflow. So use an adequate but not generous amount of grease only! Check after 1st drive to be sure there's no overflow squeezed out around the shims. If so use a Qtip to clean any excess. Don't forget to check the INSIDE pads for overflow - a bit difficult but if you have any on the outside you'll have it on the inside. Seems to work fine, doesn't burn up even under track conditions, and very little noise even with full on race pads on the street. Oh yea, it's a nice PURPLE color.

 

Excellent, thanks.

 

I was searching for a good grease to use because I wasn't sure if what I was using was good, but it turns out I am using the same kind

I am also curious; when swapping DD pads for track pads on track day, is it necessary to use the shims on the track pads, or can I just keep them on the DDs?

 

Purple power for the win

I use the ceramic high temp stuff as well.....

 

Do you use shims on your track pads? Are they just for noise control or do they serve a purpose?

 

They are more for noise than anything...I don't run them any more, But I don't street drive anymore either

 

I don't use shims on the track and i only use them on the rear when on street pads.

 

Thanks! That's good to know, because the heat destroyed my front shims and they are expensive.
