New brake calipers drag on rim

4Runner wheels.

 

I'm thinking the offset maybe off a bit?

 

I bought the truck with 168,000 on it, so I guess the previous owner put them on.

What’s weird with this caliper is that the previous one I put on two years ago did not rub at all, and this one is just a warranty replacement for that one. Should be exactly the same. I guess it’s not. I shaved them down a tiny bit with the grinder and all noise seems to be gone except in sharp left turns.

And that noise was not there yesterday before the repairs, so I guess I need to take a little more on the driver’s side. Man, I am tired of taking these wheels on and off! Guess that’s what you get when you don’t want to pay a mechanic.

 

If you look at the casting marks on the calipers, that's a different casting.

 

The differences in those Calipers is obvious. The shiny one has way more meat where it is rubbing.

 

I have 4Runner wheels and tried putting them on my truck. Guess what? They rubbed. Lol

 

like I say, I didn’t choose them. They came on the truck when I bought it from someone else, so that’s been a problem lying in wait for a while. Mostly sorted out now.

 

It’s actually not obvious in person, and they’ve definitely got less meat now.

 

Could you tell if the old calipers were ground down at all? I wonder how they fit without rubbing?

 

I would just grind the calipers a bit until they cleared. Shouldn't take more than a 1/16"

 

No, they were perfect apart from being rusty from age and salt. Same for the last part from this same brand (but maybe different manufacturer?). I can’t see that this has ever been a problem on this truck in the past, so I guess the new castings on the newer parts have slightly more beef to them and less wiggle room for me. That’s why it caught me so off guard. It had 168,000 when I got it, presumably with plenty of miles on those rims, and since I bought it from a Toyota dealer, I’ve put about 100,000.

Frustrating to discover it now, especially knowing that when I rotate my tires next I’ve got to deal with this all over again.

 

that’s pretty much what I did yesterday. Seems to have done the trick so far. Made me nervous to grind on a brand new part!

Thanks for the reply

 

Well you got it figured out on your own, and the more wrenching you do the more you'll learn.
When I first started reading through and you mentioned 17's rubbing I was thinking on the inside diameter??? How is that? But thanks for posting pictures it explained. When I rotated tires (16" TRD) on the wifes truck she brought it back right away saying it's clicking. it was rubbing slightly on the stick on weight. A small bit of grinding on the caliper fixed it right up.

 

Gotta love this forum. You will get crucified for have a 1 inch spacer lift but then people say grinding material off a brake caliper is a good idea haha.

 

I guess you've never ground on anything while working on your vehicle? Lots of excess material on most areas of the engine and other cast parts.
Why would anyone do a 1" spacer lift?

 

Excess material doesn't mean its okay just to start removing it.... especially brakes.

I think someone needs to take away your angle grinder.

 

Then there is the option to let it make its own clearance. I call that, in place machining.

 

I like how you think!

 

As long as you drive alone on private roads... have you ever seen cast aluminum wheel spokes fail? The OP already marked the spot! I mean, his new calipers did.

I know I’m late to the party but I would have just got the 1/4” wheel spacers and new longer wheel studs, those probably have never been replaced anyway and who knows how many ugga duggas from a monkey with an impact they’ve suffered through.

 

ROFLMFAO. It's called "EXCESS" for a reason. That's why the old ones fit and these don't. The outside of these has unneeded material on them.
PS: I told him to use a file not an angle grinder.
