How I Diagnosed a Seized Caliper Piston

Автокөліктер мен көлік құралдары

In this video I share my experience with a locked up caliper piston and how I diagnosed it on my 98 Nissan Frontier. While the vehicle featured in the video is a Frontier, caliper designs and points of failure are similar between most makes and models. (Always verify that any information in this video is applicable to the vehicle you are working on by using an appropriate repair manual.) There are a few methods I use in this video that may be helpful to you in your attempt to diagnose the vehicle you are working on. I did make a "more" comprehensive video going into better detail of how to diagnose locking up brakes. You are welcome to watch it. I'll have the link below. However, the video you are currently watching actually features a failed caliper. So, this video will be of help too.
!!Warning!! If your brakes are locked up its going to be very hot just after driving. The whole area that is affected is going to be very hot. Let the vehicle cool down before attempting to diagnose the problem. Don't touch a hot rotor or any hot brake component! Injury can occur. An infrared thermometer would be suggested to verify that the area is cool enough to work on.
Special notes: Some calipers have twist in pistons and will have to be collapsed in using a different method than the one shown in this video. Also, (Very Important) in the process of diagnosing you problem you may have to open the brake system (i.e. opening a bleeder or taking a line loose). If this is the case then you must make sure all the air is removed from the system before driving the vehicle. Brakes do not operate properly with air in the system. Also, of course, any loosened item will have to be tightened back up.
Here is a link to a video where I go into more detail on how to diagnose locked up brakes.

    Thank you, it indeed helped me as guidelines and i managed to pull caliper off bracket, clean some gunk that was on the outer of the brake pads, the "slide" into the smaller "thin stainless steel looking like" clips. I noticed alot of gunk inside the piston itself, previous owner had painted them red and it seems to have caused more residue than it should, i cleaned that, pushed back piston in holding it safely and having it secured by a wire in case it slips and not to stress the hose, I used a kind of big westcut that i had and manage to make the rounded shape of it lever pretty well, another oddly shaped tool i could use the corner near the handle while pressing its extremety in the sidehold of the caliper as a lever was a "file" a handheld steel file. I noticed the rubber is a little bit damaged as it been squeezed it seems, i tried to push it back in place, I took out the "slide pins" and wiped off the old grease, applied new one and made sure they slide properly.(i noticed if you dont carefuly hold the rubber extensive thingy that it slides into, it might stretch out to a point it might fissure, make sure you hold it there while you rotate motion the pins away from it/the caliper) let's hope it stays repaired, at first drive i couldnt even tell if it is fixed, it isnt stuck like previous car used to do and get blue hot metal on the disks.... :D you can do it too !!!! if you are there reading all and watching, preparing.... DO IT !!!!

    Before you start spending a couple of hours taking the wheels off and fiddling around with the brake assembly, a quick way to check for dragging brakes (caliper) is to drive the car a few miles with frequent braking, then use an infrared thermometer and measure the rotor temperature on both sides of the car. A dragging brake pad will significantly increase the temperature.

    Easiest and fastesr way to compress the pistons on calipers that have 2 or more pistons is to use one of the old brake pads or piece of steel flat stock laid across the pistons you want to compress then a decent sized C-clamp as centered on the old pad or flat stock as you can possibly get then simplu start tightening that clamp down until you feel the pistons stop and can feel through the c clamp that your now just pushing the pressure when you tighten it against the body of the caliper , which is the obvious sign that you drove them completely back into the bores. However before you ever start to compress a piston back into a caliper bore , always take the couple minute to get the outter dust seal as clean as you possibly can , blow it off real good then just quick lay on a thin film of your brake grease you should have handy for the job to lubricate the seal a bit , these couple easy and fast extra steps almost always eliminate the possibility of the seal spinning if your doing a rear caliper , or getting pinched and therefore likely also torn while compressing a standard style caliper back into place , and once that seal has the slightest hole or rip in it , kiss that brake caliper good bye because if you still put it back together and use the car as is , that caliper will seize almost certainly within less than a year , sometimes as soon as a few weeks, dirt and moisture gets in their corrodes the piston and bore anf that alone can make it seize , but also the dirt and contaminated often will sandwich themselves between the piston and the bore which of course is obviously going to cause it to inevitably seize in the not to distant future. Sorry for the long comment just wanted to add a few tips in that every one even just the weekend warrier should all know and be aware of.

    Hey Keith I have question my car has little issue. I googled the many engine related problem but I can't find solution because I do not know exactly what the problem is called. I don't know nothing about fixing car. When the car is idling the sound is loud, I can hear pulley's spinning it is not a normal sound. When I sat on my friend's car ( not brand new, low mileage) the engine idle is quietly. My car is under 26k miles. When I accelerate the engine sound is loud, and I feel little vibration as I am slowly pushing the pedal. The car vibrates for few second then its gone. I know when you press the pedal to the floor the engine get louder. I'm not pressing the pedal to the floor, at low rpm the engine sound is loud. In highway however the engine is quite. So if you have idea on what the problem could be can you help with. Thank you

    I have a 2004 Saturn VUE AWD 6cy 221,000 miles. What caused the brakes to freeze. It felt like all four froze. I was driving down the street and I was not pushing down on the brake pedal then suddenly the brakes are the stopping car. I started to depress the brake pedal but was stuck at the top, I could not push it down. I pulled off on to the emergency lane and waited for 15 to 25 minutes. I could smell asbestos. I tested to see if the brake pedal would go down as it should. It worked so I drove another 20-30 minutes and it occurred again another 20-30 minutes and it occurred again, and again. That's the pattern the brakes kept doing until I got home.

    Hello... thanks for your video. I have this nagging question about disc brakes and I have searching youtube to look for an answer and I have not found any answers on the videos that I have seen. Maybe you can help me understand. I know the theory of disc calipers; push and pull of the caliper to engage one side of the pad and the other side of the pad. On the non piston side, the slider pin/mechanism pulls the caliper "arm' (is that right?) to engage the pad to the rotors and when you let go of the brake, the caliper arm pulls the brake pad away from the rotor. Now for the piston side of the caliper is where I can't seem to comprehend. This is what little I understand. To engage the pad to the rotor, the piston pushes forward to engage the pad and when the pad is engaged, the brake fluid will continue into the piston which causes the piston arm along with the pad to pull up against the rotor. When you disengage the brake pedal, the caliper arm along with the pad will back away from the rotor. Then the piston on the caliper will back away from pressing the brake pad up against the rotor BUT how does the brake pad on the piston side back away from the rotor? Do you understand my question? Maybe it is this and correct me if I am wrong: The natural position for the caliper/piston/arm is always lets say 1/8" from the rotor. When the piston on the caliper is engaged, the piston/caliper side of things does move along with the pad to engage the rotor by way of the slider pins (still i visually can't see that) and once engaged the arm will then move the pad to engage the rotor on the caliper arm side. If this is how it works, then the piston side of the calipers I can't seem to understand how that piston side would back away the pad from the rotor. I know this is long but heck.. I'm so confused.
