Brake Noise

[cymraegs]

I did the disk brakes in a '95 non-HD, I am not used to Ford brakes and saw some creative designs that I was not used to.

we had just bought it and the brakes started grinding within a month :angry: . I rebuilt the calipers, replaced the pads with quality semi-metallics, had rotors turned, replaced all of the bushings in the line and repaired some weak spots in the lines. The passenger side hub was missing a clip and the spindle nuts were loose enough to be taken off by hand (without a wrench) :blink: .

When I had the rotors turned at a brake shop, the guy told me that they were a little warped, but that turning them would remove the warp.

Now performance is excellent in the brakes and everything appears to be perfect, except that there is an intermittent dragging noise as the vehicle moves FOWARD and when the brakes are applied there is a constant and loud absolutely horrible dragging noise from the front brakes mostly the passenger side, but coming from both front brakes. These noises do not occur when the vehicle moves in REVERSE.

Could this have something to do with those clips that hold the pads on? The repair manual only refers to them as secondary clips.

1) Are those clips supposed to be tight against the pads or loose?

2) Also what I am used to are pads that clip right onto the piston, am I supposed to glue the pads onto the piston, as there are no clips, or do they follow the piston on their own?

Or am I overlooking something entirely different?

I doubt it has anything to do with the brakes. Sounds more like bearings. When you put the spindle nuts back on did you check the bearings first? Did you follow the spindle nut proceedure and tighten them according to the book. With good bearings, the first spindle nut should be torqued to 50 ft. lb. while wiggling the rotor to make sure the bearings are seated properly. Then loosen the nut enough to get the lock nut on so the hole in it goes over the *** on the first spindle nut. Then the second spindle nut should be torqued to 150 ft. lb.

Good luck,

I didn't notice this question before.

No [-X , you don't glue them on the piston. They are mounted in position on the spindle assembly bracket before the caliper is put back in place. Maybe they are not properly positioned and that is why you hear the noise, though I can't see how you could have gotten the caliper back on if they were not in position. The other one is mounted on the caliper opposite the piston prior to installing the caliper.

Do you atleast have a Chiltons or Haynes book ?

Good luck,

I'm with Seabronc on this one. If you mounted the brakes correctly, it's probably the bearings. Don't foget to use good clean grease, like Mystik.

However, if you just rebuilt the calipers, I'd try putting on a new set.

If you, or someone that drives your Bronco rides the brake all the time, I can see where your pads and/or rotor could go bad that quickly. Just some thoughts.

Wheel bearings...

and it's possible that the spindle is bent.

I have some MT 15x10's and I know that there isn't much clearence between the calipar and rim. I noticed this when I did my brakes and I had a simple retainer clip scraping on my rim. @-)

bearings. most likley
