I have a very weird problem .... When I torque my passenger side front wheel down to 60 foot pounds which isnt even close to the 95 that is suggested the wheels locks up and wont turn. if i loosen the lug nuts it spins no problem there is nothing catching the wheel. Any one have any idea what is going on?

bad wheel bearing.

Maybe check and make sure that there is nothing between the hub and the wheel .. If they can't touch each other where the studs tighten down then when you tighten the wheel bolts it can warp the rotor enought to lock the rotor against the outer brake pad .. When you undo them a bit the rotor straightens out and the brake comes off.. Just a thought I have seen it happen on other vehicles although not a mazda

+1 The bad wheel bearing won't make sense since tightening the wheel down will push it against the hub, which will add no more extra load to the pre-load the wheel bearings are set at since that is controlled by the giant nut inside the hub. Something is causing friction and the unseated/crooked rotor would be the first thing I would look at. Tighten the lug nuts in steps, don't torque one down before the rest, make sure they are all on there good, then start the torque.

check for clearance between your wheel and caliper.

huum I don't remember saying anything about a wheel brg i'm hopeing you hit the wrong quote button .

this makes absolutely no sense, in that the wheel won't move with the difference of 60 and 95 ft-lbs.

maybe your pushing down on the wheel with enough force that it's touching the ground??!?!?!

I know this makes no sense it is boggling my mind i delivered it to my garage in sept rolled it in it has sat since... been doing my build ... and when I went to move it by pushing it it wouldnt budge so I lifted all four corners thinking that a brake caliper was seized they all spun except the front passenger so I took the wheel off and the disk spun easily I was like "WTF" put the wheel back on with the lugs hand tight it spun tightened them up with it in the air and it didnt spin.. Nothing is in the way and the wheel isn't hitting the calliper or anything any explanations?

gerald m

are the calipers a floating type or are they fixed solid .

if it spins without the wheel, but is stuck with it. then something is touching that wheel.
it has nothing to do with the hub. otherwise it would be stuck with the wheel off as well.

Either your caliper is seized or your wheels are pressing against something. Wiggle the wheel up and down when its tight on there. Is there play? How about wierd noises when the wheel is removed and you rotate the hub?

there is nothing hitting it the only thing i can think is that the rotor is warped but it was brand new before i stored it

gerald m

The only other thing I can see happening is when the vehicle was put in the garage the car sat with the brake pad pushed tight up against the rotor and either the piston is froze in the caliper or the pins that the rotor move on are froze up and the pad is tight ..When you tighten the wheel the rotor moves enough to make contact and stop the wheel from turning ,, Maybe try tightening the nuts a little at a time and checking the wheel to see when it starts to drag then you should be able to hear where the thing is touching .. Try taking the caliper off and push the pads back with a clamp then put the wheel back on and try it .. Make sure the caliper moves freely on the caliper bolts..

like sandwitching the brake rotor and pushing it against the inboard pad of the seized caliper? that makes sense

take the caliper off and put the wheel back on and try.

Another thing you could try is unbolting the caliper, then re-attaching the wheel. If it spins with the caliper dangling out of the way, you'll have narrowed down the problem.

So the problem is a combination of brand new pads, one piston stuck out a little but and when I tighten the lugs the piston is pushing the rotor out and binding

gerald m

Right on, easy fix ,, If it gives you anymore problems you should remove and rebuild the caliper, both actually they are cheap to do .. but it should be ok .. work the brakes extra for a bit and enjoy .. If it is going to remain in storage for the rest of the winter give the brake pedal a few pumps evey couple weeks ,not hard just make them move . If it is still sticking just get a big u clamp and push that pad back a bit ,,most times you can just pry them back with a big screwdriver,,

Calipers will build up trash behind the piston, so when you go to push the pistons back in, the seals have a hard time getting past the accumulated trash.

Proper brake fluid changes at good intervals alleviates this issue.

My calipers where all stuck when I changed my pads. I got them all unstuck without messing the piston seals up.
