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.

Left front tire locks up when weight is applied. Works when both tires are off the ground and free wheeling. Also the brake caliper seems to not release the pressure when the brakes are released.


you probably have a seized wheel bearing/hub assembly or frozen brake caliper - you can remove the wheel hub/bearing assembly yourself in about an hour with common hand tools (an impact wrench will really speed this up) - you can rent the wheel nut removal socket at most auto parts stores - you will have to have an automotive shop with a bearing press to remove and replace the wheel bearing ($30-$60) - if the caliper is seized - replace the entire assembly (and probably the ruined brake rotors and pads)

Smokes by pasanger front tire once in a while


sound like one of your caliper is getting stuck or lock. The seal to the piston probably worn out causing the piston in the caliper not to work properly. The piston in the calipers design to move back and forth to release the pressure off the brake disk. when the piston is lock it cause the brake pad and brake disk to rub causing much friction and heat, long period of braking can cause a fire. getting a rebuilt caliper is much easier to replace than have a mechanic rebuilding the old one. you can check if the calipers is lock up by touch and feel the outer hub of the wheel to see if its hot. if its feel hot and smell hot, replace the caliper.

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

Good afternoon, I have a Skoda Fabia Combi 1.4 TDI...


It can be the wheel Hub bearings. The rotors if warped will wear out pads early. Bad calipers are another possibility as well as a bad Master cylinder.

If the Hub bearings are bad your tires will have cupping. If the tires are okay the rotors are warping from contact with the pads. The pads won't release if the calipers are jamming OR the Master Cylinder is keeping pressure to the calipers.

You can get a pressure check done on the Master cylinder to see if the pressure is releasing when your foot is off the brake. If the pressure is releasing then the calipers are probably sticking. Make sure to use new brake hardware and a lubricate for the hardware when you assemble the calipers.

Front brakes sticking after a couple of miles


There are 2 causes, 1.caliper slides are in need of servicing/lube.2, caliper(s) piston(s) need to be serviced/cleaned. Recommend replacement of both calipers, if either doesn't work.
