nitpikker247 Posted June 30, 2015 Share Posted June 30, 2015 I have just replaced my REAR disc brakes. (Rotors, Calipers and Pads) Passenger side is OK! Drivers' side, however... The outer 1/3 of the New rotor is not being contacted by the New Pads. I figured I would switch the pads with the other side, being there was only a few hundred miles driven. No Change.Then I made sure the Slide Pins were moving Freely.They were. Figured it was a Defective Rotor. Exchanged it. No change. Then I figured it must be a defective Caliper. So I exchanged that! STILL, NO CHANGE!! When you look at the Rotor, The Inner 2/3 of Is wearing properly. The outer 1/3 still shows the Brand New Machined Surface with some Oxidation. No Wear. A N Y S U G G E S T I O N S ? ! Exasperated Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted June 30, 2015 Share Posted June 30, 2015 bent/broken caliper bracket? I think someone is gonna have to watch the brakes engage/release while a helper stands on the pedal. no sign of a bad wheel bearing I guess? Link to comment Share on other sites More sharing options...
john in KY Posted June 30, 2015 Share Posted June 30, 2015 Could the problem be defective brake pads as in not level across their faces? Link to comment Share on other sites More sharing options...
Fairtax4me Posted June 30, 2015 Share Posted June 30, 2015 Is the wear the same on both the inner and outer surfaces of the rotor? I've seen this one time, and it was due to defective rotors. The pads only made contact on the inner diameter of the rotor, but it was the same on both the inner and outer sides. What brand rotors did you buy? If there is another brand available I would try that. Link to comment Share on other sites More sharing options...
CNY_Dave Posted June 30, 2015 Share Posted June 30, 2015 Do the pads fit easily into the caliper brackets? Almost every set of subaru pads I have bought have had the tabs that go into the brackets oversize, and they don;t fit correctly 9or sometimes even at all) until I file the tabs a bit. 2 Link to comment Share on other sites More sharing options...
nitpikker247 Posted June 30, 2015 Author Share Posted June 30, 2015 The "Odd" wearing is only on the Outside of the Driver side. I switched the pads from Passenger side to Driver side and vice versa. Same problem "only" on driver side. The New rotor and caliper are the 2nd set I've tried! Not the pads. The Pads fit nicely; not jamming or wiggling loosely.

Olnick Posted June 30, 2015 Share Posted June 30, 2015 Could it be a problem with the geometry of that wheel? Has it ever been banged into a curb or something? Link to comment Share on other sites More sharing options...
Fairtax4me Posted June 30, 2015 Share Posted June 30, 2015 Was the caliper bracket replaced with the caliper? Remove the caliper bracket and make sure there is no rust, scale, or dirt on the backing plate where the bracket mounts. If the upper slider pin is the non-bolt type, remove it and make sure it isn't bent. Link to comment Share on other sites More sharing options...

nitpikker247 Posted July 8, 2015 Author Share Posted July 8, 2015 Update on the Uneven wearing on the Outside Rotor Face. I am not sure what has worked, but the Unworn face of the rotor is only about 3/16" or so. I took a narrow piece of wood and placed the butt end in the caliper opening on the back side of the brake pad as far to the outer edge as I could, and whacked it with a Small hammer to try to make better contact with the rotor. And I also tried to roughly follow abba4430's advice on brake bedding (Not to the letter though). Maybe the combination of the 2 helped the situation. Praying it will finally wear normally. Guardedly optimistic. Thanks All! Link to comment Share on other sites More sharing options...
