Last week one of the pads shattered and I lost brake pres,see "call an exorcist truck tried to kill me" post . had new calipers and pads put on ,I need to replace the rotors but have to wait till payday,thier worn past the turning point but not in danger of breaking. Now when I put on the brakes the front right makes a "clack" like a pad slaping up against the rotor but it only does it a few times then stops.They stop the truck fine ,no pulling or anything.I pulled the tire off and looked ,everything looked good and the rotor and caliper are on tight ,no play.I was thinking an air bubble in the line or at the caliper to let the piston pull back untill I push the brake peddle and it "clacks" a few times then the pres, builds back up .Any ideas?

 

if you had them put on by a service station, take it back to them. I say I think you've definitely past the tolerance on your rotors. Get them checked.

 

Had the same thing happen to my pads there are some clips available to hold the pads in place. They go on the innermost set of pads, I got mine at Advance auto. Stopped the pads from making the noise, quite as a mouse now.

 

Per Sailboat2323's post, a lot of the time the clips are left off or forgotten and the result is the "clacking". If you paid to have the brakes done, they should have the clips somewhere, they were on it. They serve to dampen noise and vibration and are necessary.

 

Yep, check the clips. And the clips can wear out, but it's as simple as bending them back a little to tighten them up against the back of the pad. At the very worst, if it's been bent a lot and has metal fatigue, you can replace it for a buck or two. I also make sure to lightly grease all of the moving surfaces of the pads and calipers, and use the blue anti-squeak stuff on the back of the pad as well. Since I switched to ceramic pads I have never had any pad/caliper related noise issues at all; but if you do a careful installation and make sure that the clips are installed properly and holding firm pressure against the pads, you should be able to do a noise-free brake job with just about any brand or price of pads. However, I would advise you to stay away from the ultra-cheap organic pads, the ones that cost about $8-10. You can end up fighting a losing battle with all sorts of annoying noises if you use the cheapest pads. Most stores carry the el cheapos, then a medium grade, and then ceramic. Sometimes they have even more grades than that. At the least, get the medium pads. They run about $25-$35. Ceramics are around $100; but to me, they are one of the very best improvements that you can make to your truck for that amount of dough. And since they last so long, in the long run they cost about the same or even less than the cheap pads. However it's the performance, lack of noise, and lack of dust that made me a believer of ceramic brake pads and I will never use any other type again. The long service life of the ceramics is the icing on the cake.

 

Service manual calls them "Anti Rattle Shims". They go under the inboard brake pad.
I ordered new caliper slides (NAPA) when I did my brakes and new shims came with them one kit per caliper.
My '88 ranger had the same setup and did the same thing with the pad falling out. It happened when I was using rivetted pads the friction material (semi metallic) cracked between the rivets and friction material falls out. One time just the friction material another time the whole pad was gone. It doesn't necessarily happen when the pads are thin one set had less than 8,000 miles on'em.
I never replaced the shim on my Ranger don't know if it was a factor on loosing brake pad.
BTW I used bonded semi metallic pads on the last brake job.
