I have a 99 Ram 1500 4wd which is pi@#ing me off. PLease HELP!!!I replaced ALL brake components, ( pads, rotors, calipers, master cylinder, fluid) after eating the pads and rotors. After doing a complete rehab of system 6 months ago, I am back to the same problem. Have ate the pads to nothing left and the rotors also. The rotors have no surface left on the back side of them except for the spokes that are at the back of the rear surface. Can anyone tell me what else could be causing the problem.

 

Have you checked if the rear brakes are doing their share of braking?

As I have had some vehicles that the rear drums would not self-adjust so as to still be able to do braking. This left the front brakes to do most to all of the braking. Very little wear on the rear brakes and heavy wear on the front.

 

what about slide pins? any problem there with binding.

what about your brake hoses ? any chance they are causing the calipers to not release. i'd think you could feel this drag.

how about wheel bearings ? do you have any wobble of the wheel where it could be moving around a dragging one side of the rotor.

since the wear out is on one side, is there anything else that could cause an alignment problem.

 

Its possible you have a brake hose that is collapsing,but I cant see that happening on both sides.Maybe a sticky caliper,but again not usually on both sides.Do you have any damage on caliper pins or slides?If your wearing out the rotors to the cooling vanes something must be dragging really badly.Did you lube the caliper pins?Give me a little more history.

 

Rear brakes have been checked and are working correctly. Just getting totalling frustrated.

 

I replaced the slide pins when I put the new calipers on. I did check the hoses and they seemed to be alright. Before installing the new calipers I put pressure on the system and got plenty of flow out of them. Anything else I could be missing? Am really frustrated.....GRRRRRRRRRRR

 

I've noticed that my front passenger side brake always wears a little fast than my drivers side...but I feel no pull when brakeing... wheel bears were replaced last year so I'm wondering if there is something causeing more pressure to go to the passengers side?

 

But are they adjusted properly? And just because the brake hoses look good does not mean they are. It would be odd that both sides would do the same thing(as mentioned above), but, the lining inside of the hose can be bad and it will let pressure flow when the brakes are applied, but restrict flow when released. There is also more to the calipers sliding freely than just the pins. The steering knuckle and the caliper have a common flat surface on them that also needs to be greased to operate correctly.

 

so what happens if you try this test...
drive around some and apply the brakes normally.
pull into the shop and leave it running.
jack up the front and spin the tires by hand.

do you feel any abnormal drag?
could the booster be riding the brakes for you?

i'm stumped on how one side of the rotor is wearing more than the other.
the pads should be centering themselves.

something's not releasing and you should be able to feel that drag when you spin the wheel by hand.

 

That flat surface has a rubber boot on it and when you squeeze it, it will open it up enough to slide a grease injection needle under it without damaging the rubber.
If you grab that slider piece, it should move freely.
This is assuming that the 99 had the dual piston calipers with the same sliders as my 2000. Mine doesn't have slide pins like older brakes, it has bolts and they go through the slider piece, I install the bolts dry because they are held securely to the caliper bracket and the slider is sandwiched between the caliper and the caliper bracket.
