My Brakes is chafing

[BattelWagun]

Alright, so my brakes is chafing.

Replaced pads and rotors about 6 months ago (OEM rotors and NAPA ceramic pads), the passenger side is completely worn down, so much that the steel backing on the pad is digging into the rotor. (thats the 'chafing' brake) Driver's side is fine, still about another 6 months left on it, the squealer isn't even close to the rotor. Now for a while it's been pulling pretty good to the right during hard stops, but I simply blamed that on a bad pitman arm... I guess not. The right side is obviously working way harder than the left, up front at least. The rears were also replaced 6 months ago, new everything. I'm assuming they're fine, so any ideas on the really uneven wear?

Powerslot cryo slotted and Hawk SD pads. Be done with it. And change out your pins/bushings. Nough said

That really sounds like a stuck/seized caliper. Is only one pad of the two on the right side down to the metal, while the other is fairly ok?

Calipers are cheap too, so when you replace the rotors and pads again I would also replace the calipers.

You can also take this oportunity to upgrade your caliper to a 3/4ton version. The cost difference from 1/2t to 3/4t is negligable. You get a slightly bigger piston so it pushes a bit harder on the pads. It's a drop-in replacement. When your buying just ask the parts counter person for a 1998 3/4t silverado caliper. I can't recall the part#'s off hand.

I can't tell yet if both pads are done, I just did a cursory examination of them last night. I bought new rotors and pads today. Sorry guys, can't afford cryo and hawk pads though... I'll post up pics of the carnage, I'm guessing that rotor has a nice ass gouge in it by now.

How's this for some worn down pads!

Uh, Bad!

For troubleshooting purposes, it matters which pad.

If both pads on one caliper are wasted, then the other caliper's piston is not working.

If only the piston side pad is wasted, then the caliper is not sliding on the mounting bracket.


Also when you put the new pads in, the squealer goes on the piston side, with the rotation of the rotor pushing the tab towards the pad, not away.

Well the piston side was wrecked, but the stationary side still had about 1/8 inch of material. The other caliper was even, with both pads at about 3/8 inch of material. So I'm guessing the caliper isn't sliding in its mount. Also, the pads I had were labeled and the squealer isn't on the piston side.

Yeah , sounds like the caliper is not moving freely. When you hit the brakes, the piston moves the inside pad first, which touches the rotor. Then the force pulls the outboard pad and caliper towards the piston and the other pad hits the rotor. This is why the inside or piston side gets the squealer since it hits first and sees slightly more wear.
