Attention: TDR Forum Junkies Let me start by saying my brakes didn't start pulling badly to the right until 36,000 miles.
I do a lot of off roading and had just returned from a trip from Southern Nevada to the cold Northwest on very dirty, icy, filthy roads. I figured things had to be grimy before I started tinkering. Also from other post, I figured replacing a bunch of parts was not the answer, besides my warranty is gone. I figured something happened to cause the problem.
I took the calipers off and noticed the mounting bolts were dirty and the bushings had fairly deep scoring on them. I cleaned ‘em up and smoothed the scars with 320 wet/dry sand paper. I packed as much grease under the bushing as I could. The bore and rubber sleeve the mounting bolts go into were also gummed up. I cleaned and greased them. I haven't figured out why the metal bushings (on the Allen bolts) could be scarred so bad when riding in a rubber bushing? Dirt, I guess. I cleaned up the calipers and remounted them with out the pads to see if they would slide proper. At this time I noticed they had rub marks where they ride close to the mounting arm. The machining on these calipers is really crude so I used some 320 grit wet/dry and cleaned ‘em up. Good, now they slide easily, even when a lot of upward pressure is put on them. The manual says to put some grease here but I didn't. It seems the mounting bolts, bushing and rubber sleeve have lots of "give" and will easily allow the calipers to rub on the mounting arm. I swapped pads (right on left and left on right) and put it back together. NO PULL! I can let go of the wheel and it stops straight and true... ..... It's fun to drive again.
I think a combination of dirt, too loose tolerances in the mounting bolts and rubber bushing and very poor machining on the calipers combine to make for a sticky set up. Possibly as the brakes are applied, the rotor forces the caliper up into the mounting bracket, and with the poor machining the calipers bind on the bracket before the calipers can slide to exert equal pressure on both pads? Maybe it was just swapping pads? I don't know but it worked for me. It may be temporary but so far I am a Happy Camper!
