Brake pad=MIA...

[Bluebird]

:--) I noticed a grinding noise in the front left brake pad. Took it apart and found that the outboard pad was gone! The backing plate of the pad was grinding my rotor Replaced pads both sides, rotor on left, I'll replace the right in a few miles. The pads had 23k miles, the right side was 50% used. What do you think happed The truck never pulled to either side, even when it was grinding. Thanks in advance for any of your experience, thoughts, insights... Patrick.

I had a Ford do that on me, but it was a brand new pad, apparently it wasnt manufactured properly and within 100 miles the pad just fell off the backing, truck definately pulled though.

I've seen uneven pad wear if the calipers can't slide freely -- but not quite as bad as yours . . .

Sticky caliper mount will cause that. A bad caliper piston that won't release correctly also tends to make a mess of things. Most of these calipers have a non-metallic piston and the can stick. The most common is just bad manufacturing and the pad peels right off the backing plate. Rear brakes non-functional or not working correctly tends to load the front beyond what it should be doing. In addition to accelerated wear things tend to fall apart under the heat and load.



About the same thing happened to my truck with less than 20k on the shoes. I never heard a grinding or experienced any pulling but when I pulled the rotors both were toast. One inboard and one outboard the pads were down to the rivets and eating the rotors up. I know my rear brakes have been prettu bad so I am sure it contributed partially but I think I need to clean up caliper mounts and get some new calipers with the steel pistons.

I had a similar problem a few years ago with my 93. The caliper was sticking. It doesn't take much to wear down a pad, especialy if the caliper makes the pad drag slightly on the rotor after the brake is released. lWhen I replaced the caliper, I filed and cleaned up the slides and pads so there were no rough spots and made sure everything moved freely. Then I used caliper grease to lub the slides. Seems to be working better.



Not sure if this will help you much.

I've also heard that anti-seize compound will work good on the slider surfaces - I guess it withstands the heat pretty well. That's probably the same stuff you're reffering too Stan(?)

There is specific caliper grease. If you use regular antiseeze the brake heat will melt it and get the anti seeze on the rotors. Not good for stopping. The "caliper grease" is supposed to withstand the heat better.

I used Permatex synthetic caliper lube on my '92 and it is working great so far.
