I just rebuilt my front end with the trail gear seal kit. My old calipers were seizing up so I replaced them with new ones from o Reilly's. Now the rotor is grinding on the caliper after putting everything back together. On the passenger side and really close in the driver side. My truck is a 94 v6 with 94 calipers. Any ideas?

 

I am guessing you just swapped the old cores without comparing the old and new calipers .

Only can be you got one boxed wrong or some how installed it wrong

just poor quality control ??

Didn`t put them on upside down ??

 

You said you rebuilt the front end with TG seal kit, is this a SAS rig with IFS hubs? perhaps you got solid axle calipers which have a smaller gap then IFS calipers. If you told Oriellys you had a solid axle front end, or they just screwed up and gave you them on accident.

 

I had my chick take the old ones to O'Reillys. So I didn't do a comparison. They both have the same castings n ridges in the front. It's not upside down or anything like that.

 

Yes. A 1994 v6 4x4. Did the trail gear sas kit and a 85 front. When I got the axle. My buddy said it was set up to use my calipers. Allready had the rotors on and he said ifs hubs. They are 94 calipers tho. Before I started the tear down. The pass calipers started to grind on the rotor a lil. I'm jus goin to clearance the inner area of the calipers 1/4 of an inch. Hopefully that helps. Has anyone had this issue. N thanks for the help.

 

Some pics would help. Where exactly is it rubbing? On the sides or top of groove? You shouldn't have to grind the caliper, somethings not right. A quarter inch is alot of grinding, there are internal fluid passages in the caliper and grinding into one will junk the thing. Brakes aren't something you ever want to hokey rig, your and other lifes depend on them.
