You brake HOSE may have deteriorated, and is not allowing fluidto drain out of the caliper piston. I found out after a piston, caliper, two disks. The wheel would LOCK UP it got so bad.

It can be rebuilt, but it is easier and cheaper to buy a new one. these usually run about 15 bucks. not worth your time trying to fix the one you have. replace it.

Got on highway last week car started shimming got home front wheel was burning hot replaced front caliber drove 120 miles fine now today have same promblem


You might want to have a mechanic take a look at your
master cylinder, especially if you replaced the brake caliper on the hot wheel. If you didn't replace the brake caliper on the hot wheel, you should do that first. They do go bad from time to time. They can get stuck in the on-braking position and drag and cause all that heat to build up. Shimmy was probably caused by a heat warped rotor.

My steering wheel shakes when braking over 40 mph


most likely a warped rotor, check front end components (tie rod ends, ball joints). if a caliper is sticking the rotor will get very hot, get black, or discolor, and bend (warp). drive around for10 min. and jab the brakes hard several times during the drive. stop and feel the temp (don't touch) of each wheel with your hand. they should be equally warm. hot or smoking is not a good caliper.

Back wheel sqeaking and getting hot


The following asumes only one wheel is hot and the e-brake is not engaged or possibly hung up from having been left on while the car was not driven for a while. Up north, BMW (Audi ?) brake disks tend to start rusting after about a week of inactivity. For a hung up e-brake, it is sometimes necessary to go back and forth to break the corrosion.

A hot wheel usually indicates that the brake pad is dragging (i.e. the brake caliper piston is not returning into the brake caliper bore).
A couple of checks: measure the brake disk temperature with a temperature gun on both brake disks of the same axle. If one is much higher, the caliper piston is probably sticking. Can also check for relatively large temperature difference with your hand-just do not touch the metal or you will get burned. Look at the brake disk for evidence of the outline of the brake pad that may have transferred to it indicating a very hot brake disk. Chock the car well, put into neutral with e-brake off, jack up "hot wheel" side and try to spin the tire. If a lot of drag, sticking caliper piston. Caliper replacement or disassembly for a thorough cleaning will probably be required. If this is necessary, you should do both brake disks and pads and consider doing both calipers on that axle depending on age and corrosion condition.

My 2004 honda cr-v has a burning smell coming from my right rear tire and the rim gets real hot. my calipers and brake pads were replaced but the burning smell is still present and the rims gets hot


The wheel bearings are going out. Most of the time you can replace them easily but some newer vehicles like yours might have a sealed hub in which you must replace the entire assembly

Front wheelsmoking and smelling like burn brakes


Shaky steering can be alot of things, so lets start with probable causes. Wheel alignment, wheels not balanced, worn out suspension or linkage. The smoking and burned brake smell could be the same problem if the caliper is sticking, this too can cause a shimmy or shake in the wheel... You really need to get those front wheels off and take a good look. If your not really privy to what exactly your looking for please take it to your trusted mechanic, and have them check it out...Good Luck!!

2006 chrysler pacifica-wheel hubs burning hot


The problem might have already been there,the steel wheels are making it noticeable,because they don`t cool down as quick.Most likely is the calipers sticking,or you have a set of high dollar brake pads on the vehicle,and they are heating the rotors up.The high dollar pads are a very hard composite pad witch produce a lot of friction,and heat as a sort of side affect.

Super hot lug nuts


Sounds like the wheel bearing is bad - when it is, the friction inside the hub goes up and the hub gets heated, sometimes to scalding temperatures. You should immediately look into getting this handled - a fully failed wheel bearing may cause the wheel to lock up at speed, potentially causing a crash.
