LegacyKid5 Posted July 14, 2017 Share Posted July 14, 2017 Ok I'm stumped... I'm working with Ken at KNS brakes to trying and solve the issue but figured I'd see if anyone is thinking h of something we're not. Long story short, the bolts that hold the caliper to the adapter bracket in the rear sticks out .5 to 1mm to far and makes contact with the rotor, as you can see in this picture. I've talked to Ken and measured the bolt, it's the correct length, the bracket is on correctly and I used a washer as instructed. That being said, I'm shipping the brackets and hardware back to Ken so he can see if it happens on his setup as well. He tried a handful of brackets/hardware he had in stock and there was no issue. So my question is am I missing something? Could there be anything with the backing plate and/or hub that is causing an issue? The only thing I can think is maybe the bracket is to thin in the one spot. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Andy_Mac Posted July 14, 2017 Share Posted July 14, 2017 Is there space for a washer on the head side of the bolt? Or get a slighlty shorter bolt. As long as the caliper is centred where it should be it shouldn't be an issue worth stressing over. 2000 Legacy B4 RSK - SOLD 2006 Legacy BP5 GT Spec B wagon - Garage Thread 2011 VW T5 van 2.0L of turbo diesel awesomeness Link to comment Share on other sites More sharing options...
Max Capacity Posted July 14, 2017 Share Posted July 14, 2017 Get a thicker washer....or grind off that end of the bolt to make it a little shorter. Or leave it there and the rotor will grind it off or adjust to have clearance... But I think you want to grind off that end of the bolt. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

MilesA Posted July 14, 2017 Share Posted July 14, 2017 Just grind off the excess from the end of the bolt (as said above). Too easy. Link to comment Share on other sites More sharing options...
LegacyKid5 Posted July 14, 2017 Author Share Posted July 14, 2017 Grinding off the bolt or a thicker washer will solve the issue, no doubt. The only concerning part is that Ken has never seen this issue with any of the kits, so the fact that it's even occurring is bizzare. Link to comment Share on other sites More sharing options...
gkinslow Posted July 14, 2017 Share Posted July 14, 2017 I'd go with a thicker washer. Grinding off the end of the bolt could make it harder to get started next time you are assembling everything. Especially if its mot something you do on a regular basis. Link to comment Share on other sites More sharing options...

Yeah I would definitely go with the washer route. The brackets and hardware are actually going back to Ken at KNS right now so he can see if there is the same issue on his test setup with these brackets/hardware. Which is why I am asking if there is anything with the car that could possibly be causing the issue, considering that it's the only time he's had anyone experience this issue.

Max Capacity Posted July 14, 2017 Share Posted July 14, 2017 The bolts and washers are commonly produced parts, quality control is out the door. This kit may have been the one that got the "compound of tolerances" messed up. You got longer bolts and thinner washers in one kit. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

This kit may have been the one that got the "compound of tolerances" messed up. You got longer bolts and thinner washers in one kit. That was my first thought, but the bolts measured out to exactly 35mm as Ken said they are supposed to. So it could be that the washers are not the correct thickness. Otherwise I'm stumped, if the rotor was somehow seated (which I can't imagine is even possible) too far back then I would assume it wouldn't line up with the caliper and if the bracket happened to be to thin then the caliper would be to recessed and again not align with the rotor.

JmP6889928 Posted July 15, 2017 Share Posted July 15, 2017 Grind the end of the bolts off so they are flush with the bracket. Put a bit of a taper on the ends after you grind them and run a die over the bolt. Easy fix. Link to comment Share on other sites More sharing options...
LegacyKid5 Posted July 15, 2017 Author Share Posted July 15, 2017 I appreciate all the suggestions to add a washer or grind the bolt, I know either of those would be a solution. My point in making the post was to see if there was anything else that could be causing the issue given that no one else has had this issue with the same parts and my hardware and brackets measured out to exactly what they're supposed to.

wpmarky Posted July 17, 2017 Share Posted July 17, 2017 mine did the same, we grinded it down. Link to comment Share on other sites More sharing options...
LegacyKid5 Posted July 17, 2017 Author Share Posted July 17, 2017 mine did the same, we grinded it down. That's good to know I'm not the only one it has happened too, I was under the impression it was an isolated issue. Thanks for sharing you had the same problem!
