I could not figure out why my 4 lug breaks were so shitty after I had worked on them but today I figured it out.. I just don't know WHY it's doing this..

The front break pads are only griping the top half of the rotor on both sides.. if that makes sense.. okay when I look at my rotors.. the top half is shinny.. while the bottom half is all rusted.. I took one of them apart and looked at the pad.. yup it was wearing only on the top half and the bottom half wasn't wearing.. I put it back together and tested it didn't help.. both front rotors are doing this..

I just did a lot of work on the breaks and I think I must have put something back together wrong becase the rotors we both remachined, ss breaklines put in, the breaks have been bled to death, replaced the fluid with synthetic, replaced the pads with Hawk HPS

The only thing I can possible think of is that the "spring" thingy isn't on there right.. I have looked in the FSM and there isn't a description on how it's supposed to mount.. I think it connects to the inside but where exactly does the rest of it go?

THANKS!

definately the calipers. Have them checked out, possible need a rebuild.

bump.. come on someone knows how that supid spring thing is supposed to sit in there.. Ima gonna go pay with it again..

Okay I think I figured it out.. anyone want to confirm..

The springs only real job looks to be to push the pad away from the rotor when not breaking.. before the part fo teh spring away from the piston was actualy on the pad pressing down..

I found out you can take that extra part and push it up inside the caliper so it doesnt' touch the pad...

That's mighty weird. As for the spring, that's just there to keep the pads from rattling around when you're not using the brakes. It sounds to me like the rotors weren't cut accurately. Have your machine shop measure them again to be sure they're a consistent thickness across the entire contact surface. From your description, it sounds like they are thicker on the upper half than on the lower, and only the upper is contacting the brake pad.

I would definetly take them off to make sure that you didnt warp the rotors which is a posibility. How did you break them in usually it comes with instructions?

Okay well I figured out what I did wrong.. I had the spring in there wrong. The spring is supposed to attach to the pad closest to the piston and then rest on the actualy caliper itself.. I was putting it on down on the pad and when it compressed it was obviously not applying equal pressue across the entire surface.

The second I pressed down on the pedal I knew it was right.. I have 100% better pedal feel right now. TONS of pressure and after 2-3 stops it took all the rust off the calipers.

Okay well once again I learned a lesson.. I think 90% of my problems are mistakes that I myself make :-/
