: Wheels rubbing on brakes

Alright, so my trail rims don't clear the brake calipers in the front. They rub slightly. So, I have two options:

1) Grind a little off the rims, or

2) Find some .25" spacers to stick in there.

Anyone have any experience on this?

I would prefer to just stick a spacer in there. Discount Tire guy siad I could probably find something like that on summit. The rims I am running are the plain black steel ones. The back brakes are drums, so clearance there is not an issue.

Thanks

Mickey Thompson makes a spacer specially for the tacos. When they first came out guys were just throwing chevy wheels on them and having the same problem, so they developed a set of spacers to combat that problem. you can get them from any MT dealer. They are...I think $13.80 each

i had the same problem, grind a little off the caliper, the caliper is thick enough to do so. i did it and no problems..

Yeah I ground my caliper too, it looks like theres a fluid passage way where that one bulge is but I tried to stay away from that, Im not sure if its the best idea but if you say its thick enough that makes me feel better anyway. Did you paint anything on it to keep it from rusting?

Grind the caliper, not the rim.

how much can I take off without it being too much?

I would not grind the caliper. They made them that thick for a reason. On my 04 I had the same wheel and grinded about 1/4in off the caliper but when I tq the lug nuts it still rubbed. I didn't want to take anymore off so I found some used ones, replaced them and got new wheel. Lesson learned do it right the first time.

If you have not mounted tires on them yet send them back and order some from wheelersoffroad.com. They will clear the calipers. If you have mounted the tires, just put them up for sale.

i just put some new 15x10 3.7" bs with Goodyear Wrangler MTR's 35x12.5R15
I had an issue with the calipers as well
the fab shop that I used did some grinding of the caliper and the new holes on the rim were ground down a bit, too

Thats kinda surprising that the fab shop ground on your calipers, See everyone it must be ok!

Ronal makes the alloy wheels for Toyota...here is what they have to say!

the section on the spacers is about 3/4's the way down the page!!

grinding on the calipers or wheels can effect their function greatly... the safe bet is to either take back the wheels and get the proper size and back space or get the right spacer!!

the calipers are designed and weighted specifically for their functionality... removing significant enough material to make them fit can effect so many factors of how the brake system works you may cause problems and not realize it until there is a failure...as the brake pads wear the position of the caliper can change to, so even if you fit them now by removing material down the road they may end up not fitting again!!

well I really think your wrong about the position of the caliper moving as the brake pad wears, theyre fixed. And what do you mean theyre weighted? The only thing I can see that is a bad Idea is if you go too far and you end up putting a hole in them and you get fluid oozing out. Heat could be another issue, but you just shve a tiny bit off so you not loosing much mass.

"Brakes: A word of caution in choosing wheels.* Naturally they must clear the brake calipers for proper fitment.* Some OEM brakes, utilize a floating brake caliper.* This will allow some wheels to fit, once the brakes have worn down some, however when the pads are replaced, the wheels will not fit, in that the caliper will hit on the back of the spokes.* Take care to consider this when making your purchase.* Considerations should also be taken if you are planning in purchasing a larger brake caliper kit, too.." from the Ronal page I posted...

on the Taco they are fixed so yeah that isn't a issue in that case the pistons,pads adjust to the disc but a RAV4 that has floating calipers it is...in general terms I was covering the bases because not every Toyota 4x4 has fixed calipers....

looking at this pic you see the two sides of a fixed caliper are bolted together they are generally supposed to weigh equal amounts to keep each side balanced to keep equal stress on the bolts...plus there are structural design features on them to enhance the casting strength of each side... not to mention the internal fluid chambers...calipers are beefy for a reason...usually clearance issues will not be fixed by removing small amounts from the outside half of the caliper...on the caliper pictured if you remove the fins on top of the far side(the outside of the caliper) you are losing the structural integrity of that casting...since calipers are cast modifying them is a bad idea!

and yes the brakes need proper ventilation...to close of a wheel fitment can contribute to heat problems and as gases build during braking if they can't escape you lose friction ...there are low pressure pockets of air that can build between the wheel and the disc and contribute to brake efficiency lose...and on and on and on.....

i've heard that there are three different sizes of calibers that have found there way on tacos. I work at a toyota motor manufactureing plant so i'll add my $.02.

THE BELOW IS WHAT I THINK NOT A 100% FACT!!!
The calipers are cast. meaning they are made by having liquid metal forced into a mold. The only reason that the calibers are diffenrt physical sizes is they are coming out of different molds (I THINK!!!!) So shaving a bit off the larger calibers should not pose that great a risk. I'm not saying to go out with yout mini grinder and hack away. I just don't see taking a SMALL about off for wheel clearance to be a major issue. I'm personally not going to fool with shaving the calibers. If the rims i order don't fit i'll return them for 16"ers and just bit it on the tire bill............
