Brake Rotors Binding

crusher350 · October 27, 2014

Hi guys,

Changed out my front pads and rotors on my 1997 Jimmy when I ran into an issue. The new rotors seemed to be binding, I was unable to rotate the wheel, stuck solid. I noticed when I put the caliper pins(non floating stationery style pins) back in they were touching the top of the rotor surface..rubbing big time and the new pads were very tight against the rotor surface even though the piston was all the way back in the sleeve.... Seems like the rotors are to big??? circumference seemed a bit bigger than my OEM. I told the guy at the parts counter to give me OEM....I put in Wagner rotors.......I have done tons of brake jobs on my other cars before, never ran into this issue....

What gives???

Im guessing wrong rotors? Or pistons stuck in caliper and not releasing.

If the pins are dragging on the rotor edge, doesn't it have to be that the rotors are too large in diameter?

He may have fat fingered the info on your car or transposed from numbers when he pulled them from the shelf. Where did you get the parts from? You could look up on there website to verify the parts received are what is called for on your vehicle. I know when I pull mine up I get a couple different options but what they don't give in the descriptions is for the options that I may/may not have that pin point the exact parts I need.

Measured my original rotors and they are 10.5 inch in diameter...The ones he gave me were Wagners and they were 10.82 inches after I measured them ...On there system it says that the Wagners are a direct fit for my 97 Jimmy ...The other brands they had were also the same size... no 10.5 inch . I went online at RockAuto and bought Raybestos 10.5 inch rotors.....Installed them today and they fit like a glove.

Yes sure enough if you look up rotors on the Wagner site for 1997 Jimmy it says 275mm (10.82").
