The rear wheels get really hot. A laser temp reading runs 150-190 degrees. Pretty hot to touch. Is this normal? Had a brake shop check the brakes (I installed new) to make sure they were not dragging. Maybe it has always been this way and I am just now noticing it.

What would be a normal running temp for the wheels?

you need a higher quality infrared test gun to provide a second opinion as to the actual temps,
no the wheels do not generally run at that high temp, somethings wrong, you'll want to locate the source of the heat and check all four wheels
maybe you left the parking brake partially on or a wheel bearing is going bad?

cheap works ok
I have a very high quality infrared and several lower quality versions of infrared temp guns, to use in locating issues like that and sources if parts fail.

higher quality sure wont hurt either

verify the temp and check the surrounding parts like the differential to locate the higher heat locations as you might find its the differential, or the brakes that are the source of the heat

IF YOU CAN,T SMOKE THE TIRES AT WILL,FROM A 60 MPH ROLLING START YOUR ENGINE NEEDS MORE WORK!!"!
IF YOU CAN , YOU NEED BETTER TIRES AND YOUR SUSPENSION NEEDS MORE WORK!!

I do not see 150 to 190 degrees hot by any means. most vehicles have components well above those temperatures without any issues.

There is a certain amount of heat generated from friction whether the brakes are applied or not. You get heat transfer from the differential and some heat generated from the tires running on the road. That heat transfers somewhere.

If it is hot enough to generate a smell, then something is up. Otherwise, I do not see any issues.

People fear change because it threatens what they know, or what they claim to know.

I agree on the wheel bearing as being the possible
issue.
I had mine go out and the heat welded the bear to
the spindle, and I had to replace the spindle. Definitely something to look at.

how long does it take to get this hot?
how much do you use your brakes?
front brakes should be hotter than rears.

70 L camino, grampa engine, g-force 5 spd, road rage suspension. Pray first before all else fails.

I had this happen last year on my rear brakes. I just had both sides replaced with shoes, cylinders, etc. Mine just need to be adjusted and if I remember correctly I adjusted the parking brake.

Always adjust the parking brake after you adjust the linings. If the cables for the e-brake are taught, then back off of the adjuster till there is slack in them, and then adjust the linings. The next thing to do is to get into the car and depress the brake pedal to make sure that the linings are centered in the drum, by rotating the drum and listening for a very slight drag on the linings. Then you adjust the parking brake to the setting in the assembly manual, and you are finished with the project.

Never argue with an idiot. He'll drag you down to his level, then beat you with experience.
