New rear tire and now everything is running hot?

Energy One
Just got a new tire and new bearings put on at the shop. Should the brake caliper, disk and belt sprocket be hot after riding it in town. It is hot enough you cant hold your hand on it but not red hot. Brake disc is moving back and forth so I know its not that I believe anyways. Thanks never really checked for heat in these areas until checking over the tire.

Brakes always get hot when you use them. After all, the pads clamp on the rotor, and that friction is how the brakes stop the bike. Friction makes heat. After riding and using the brake, the rotor will be too hot to touch..that's normal.
Maybe if you are concerned, you should ride it for a while and only use the front brake, then touch both rotors...then you'll see.
 
Thanks that makes sense. I temped it and the caliper is 135 in the hottest spot. The disc is 130 in the hottest spot. The hub and by the bearings are 115. This is with out using the back brake on a 5 mile drive. The brakes are making a funny noise in the back like a chatter that is what made me grab them in the first place. Thinking with the new tire in place the brake shoes are not perfectly lined up and will wear in. The disc will move so its not to out of wack.

A new tire makes no difference at all. But when you remove the brake reservoir, there are usually some spacers installed to center the unit on the rotor. If those are not put back exactly the same, it can be slightly off center and the brakes will not bite as well as they should.
Sometimes the pistons in the reservoir get gummed up with dirt and won't back off like they should, and that will cause a brake pad to ride and heat up.
Did you look at your brake pads when you had it apart? They should be inspected for even wear, and some guys like to scuff them up a bit because they can get a glaze on them, especially if you have an oil seep back there anywhere.
You didn't specify: Did you replace the brake shoes too?
Does the brake bite like it should and stop the bike like before?

Thise temps don't seem abnormal. I would have thought a bit warmer
 
No I had a shop do the work he said bleed the brakes a little so I did. The disc does move a little freely so I know its not real tight. No the brakes where removed just to replace the tire and new wheel bearings. I just had new bearings put in since the bike is an 05. The rear of the bike never made this noise before it sounds like a loose chatter. Probably from the brake disc. Does not do the noise all the time. This is what made me check for temp so I have no Idea what the temps where before.

Push the pads back into the caliper. This eliminates any drag on the disc. Bring the temp gun. Ride one mile, dismount, shoot the bearing housing in the hub first. See which side, or which bearing is hotter in other words. Now shoot the disc, caliper, and belt/chain [whichever applies]. Ride two miles farther out or more and pull over. Who is warming up bearing wise?

Can the center collar come out of the wheel if removed? The seals keep the bearings in place so the collar can't come out? Then no center collar missing and someone torqued on the axle and now the bearings are forced on the races, etc.

The loose clatter could be that your anti rattle springs and not locked in behind the pad. This could cause the pad to move around inside the caliper and ride up unevenly against the rotor. I am in the process ofchainging my front and rear pads now let me know if you need and pics

Thanks, That could be the problem. I did not know about that. I will check it out in the morning.

See if this makes sense. Loose, noisy brake pads is a good sound to hear. Why? Because the pistons can retract away from the pads and now the pads rattle with any hard bump, normal riding, etc. Better known as 'friction free,' where pad wear is banged away from the disc so no excessive or noticeable wear is present.

Squid ear: Oh shit I better fix it somethings wrong.
Racer's ear: Happily ignores it.
 
I checked the Spring out on the brakes. They are in place. backed the brake caliper off a little more and went for a ten mile ride. Bearings and hubs where 100 degrees. The disc was 115. So was the inside of the brake caliper. It is 95 out today so I think its doing much better. Thanks for all the input and fast responses!
