Saw a cool trick for reinstalling the piston, use a little air to push the boot out around the piston while pushing it into the caliper. I like installing the boot into the caliper before the piston goes in.
You Don't need a friend to spread the new boot out...to install the piston...remove the bleeder ..hold the piston gently against the top of the new boot then apply light air pressure to the bleed hole and the new boot will pop over the piston the remove the blow gun and the new boot will suck in the piston with the boot on perfectly
On my 2006 Mazda BT 50, my front right caliper was dragging slightly. I just removed the O ring & dust boot & gave it a good clean & put everything back. It now works as it should.
Thanks! I always forget how to do this since I don't do it that often. I also like to completely derust and clean then paint the caliper, bracket and inside of the piston when I do this but it's pretty labor-intensive and not truly necessary. But it keeps things clean and prevents rust and future seizing.
I use to "rebuild" brake calibers myself. Now part stores don't carry rebuild kits. Plus, most calipers are inexpensive and better to just buy a rebuilt one that's already cleaned and ready to go. The time it takes to rebuild one and clean it eats up the cost of just replacing it. Today, every min is accounted for when charging to repair vehicles. In the past, we would do things like cleaning up the part and not charge for it. Now, you can't survive spending your time and not charging. I ask people if it's so easy, why don't you do it? They usually respond, "I don't want to." So why are you complaining about paying me then? Don't tell me something only took a few min and expect it free. I don't ask you to do your job without being paid.
Ok... Nobody is expecting free work, and I wouldn't go to any mechanic who doesn't have the time to do the job right. Not exactly rocket science, it's manual labor.
@MJ Actually, a lot of people expect free work. That's one point in saying it only takes 5 min to do something, to make it clear you think it should be free or cheap. And there's a misconception out there. If you're a good mechanic, eventually you will be so far behind, that everyone starts thinking you're slow. It's not that you're slow or don't have time, but one mechanic can only do jobs so quick. Some are 1 hr jobs, some are 40hr or more jobs. When everyone wants you to work on their stuff, you spread it out and schedule further out. I have people waiting 6 months for me to get to them. Some say I'm slow, and they can't wait that long. Also, just because you pay someone good money doesn't mean you're getting work that is worth what you're paying. Paying a dealer $180/hr is getting the same mechanic doing jobs on the side for $50/hr. That doesn't mean the guy is taking more time to do the same job at the dealership. It just means you're paying more because you think you're getting better work done, which you're not. At the same time, I wouldn't trust a mechanic that is only charging $35/hr, or has a vehicle for 2 weeks for a 1 hr job.
Do you really trust your life to some Chinese slave that rebuilt scores of calipers all day in a dank factory for the cheapest/fastest possible method?
It's for people who are doing DIY, not for mechanics. Sure, a mechanic doesn't have time to do the whole rebuild, and would rather replace the whole caliper, but for a DIY person, the boot kit is much cheaper than a new or rebuilt caliper. Time isn't an issue for DIY like it is for a professional.
Well, knock on wood, but I didn’t know this is something I needed to know and I am glad I ran into this for future reference. Great video. Hopefully I won’t have to do this anytime soon. But you sure made it look easy enough. Thanks man. Great quality.
Noted a tip on that from the ETCG channel...he covers the business end of a needle nosed vise clamp with fuel line hose to gently clamp & compress the opened brake line to keep it from gravity bleeding out. Have not tried that yet myself but it looked effective enough imo.
dust,dirt and water will get into the torn boot and end up corroding the piston which then jams up and will not retract when you release the brake, this then wears out the brake pad extremely rapidly. You may end up with pads like new on the good wheel and completely worn down to the bare metal and scraping the brake disc on the side with the damaged boot.
Can you just change the dust boot without removing the piston and disconnecting the caliper from the brake line ? Basically, does it just pop off for a quick fix or not?
Hope you are getting better quality than we get in the UK we can't get a one year out off the after market crap and they cost 30 to 40 sterling for front only
Yes you can has sooner you don't Pop the piston completely only the far has you can work the area and remove the boot, it's not going to leak unless it's very damage, if it's leaking willed changing the dust cover that means your inner seal it's done and you have to replace all, has sooner the piston it's not damage, crack or has deep oxidation you are good only polish very well the piston and you can reused, I said polish not Dremel with a rock disk or wire cleaner only polish I will like to be very clear on that. Now if you want to clean the grouts we're the dust boot seal well yes you can use a wire cleaner Dremel, easy not to hard have to be very careful you doing to much and that piston it's done have a nice one.

I noticed a small cut in my piston boot there is no light coming through just a small nic like 1 to 2mm. Do you think i should replace it? Thanks in advance Am I right in thinking it just stops dirt getting in not fluid from coming out?
Damn it!!! I also saw a tiny tear on my boot today. And it's practically in the same place. That's why I am here. Do I really need to replace the boot? Can I just leave it be? Will brake fluid leak out when I press the brakes?
Crud and dust will build up on the piston, then rust on surface begins to set in hence compromising the smooth piston surface needed to work correctly. So the workings of that piston/braking on that caliper will erode and will need replacing soon enough anyway. It stinks but these things tend to a create domino effect of probs when untended so imo I would remedy it sooner rather than later.
One guy can do that a lot quicker hold the piston to the top of the boot and put a quick blast of air in the line hole and the boot will form right around the piston done
Omg I have a 2016 Mercedes CLA I am changing the brakes and the rotors and I accidentally stepped on the brakes and the piston shot out😮. Did I ruin my car?
Obviously easier, less time consuming and inexpensive to install a different/new calliper for those who's running a business but theres a few reasons some of us do DIY like not having the money the internet is full of knowledge but without the experience it sometimes seems worthless
You can do that with the car turned off but only for a limited amount of times until the brakepump is out of "strength" i guess, then you need to start the car for the brakepump to build up pressure again.
Also search for caliper rebuild kits and certain websites that deal with part rebuild kits will pop up as well I do it a lot myself and 1500 grit sandpaper to polish the pistons before lube and reassembly it will slide in with almost zero effort
Don't buy after market anything I replaced the front calipers on sprinter van as brakes were seizing up and so did the new aftermarket when the pads got to half worn Same with dust kit can't get a year out off them till they are all cracked however this is uk 🇬🇧 maybe you get better quality
Boot replacement kit runs around $10; a rebuilt caliper will run more than $100. If money is of no concern, or you do not want to do this simple repair yourself then of course it is a lot easier to simply hire a mechanic to do your brakes. You usually will not find a torn boot unless you are already doing the brakes yourself anyway.
@@rafars2246 brake fluid definitely functions as a lubricant in your brake cylinder. If the boot replacement kit comes with a silicone lubricant it will have been approved for use on the boot and is good to use it. Untested silicone lubricants may deteriorate the boot.
@@deltasquared7777 Well, I use 3m hehe. Everything has a place and it is shocking to see even "mechanics" not knowing how to lubricate brakes. There are guys using silicone on the brake pads, crazy stuff...
Why not just spend a few more bucks and buy a whole Brake caliper ? save the trouble and time and plus the headache of thinking that rubber won't last lol 😆

Tip. Put the boot onto the piston then slide in carefully. My two bits... Like videos that are to the point.

In tech school, they taught us how to use a rubber-tipped blowgun on the bleeder screw hole to pop the piston out.
How do you stop the brake line from leaking fluid after you remove the caliper?
Noted a tip on that from the ETCG channel...he covers the business end of a needle nosed vise clamp with fuel line hose to gently clamp & compress the opened brake line to keep it from gravity bleeding out. Have not tried that yet myself but it looked effective enough imo.
In Russia, we sell a special tool for surviving a rubber brake line. then you unscrew it on the caliper and the brake fluid does not flow.
I just don’t take the whole caliper off 🤷🏻♂️ no need to disconnect really . Taking it off just means easier access tbh
good extremely rusted break cylinder & piston replacement with inner & outer rubber seals 👍👍🇵🇰
I need do that I found that rubber is brake in my mitsubishi asx when I clean breakes. And also I see now why my breakes pads they don't rub evenly
Is IT important to change the brake piston rubber dust cover if its Not leaking..mine ha a hole but no leak..Thank you
May have already leaked in the past and is now dry 🤷♂️
dust,dirt and water will get into the torn boot and end up corroding the piston which then jams up and will not retract when you release the brake, this then wears out the brake pad extremely rapidly.

Can you just change the dust boot without removing the piston and disconnecting the caliper from the brake line
? Basically, does it just pop off for a quick fix or not?
Disconnecting caliper from the brake line is not necessary. But I think you have to remove piston in order to replace dust boot.
Hope you are getting better quality than we get in the UK we can't get a one year out off the after market crap and they cost 30 to 40 sterling for front only

the seal has smaller diameter for the portion that goes into the grove , and a larger diameter that sits in the caliper ? is that right?

Is Ebay the best place to order new rubber seals?
Rock Auto is good. Ebay has a lot of counterfeit or knockoff parts. Not the case with Rock Auto.

A question. Where do you order boot from.. thank you excellent. Video!!
Thanks
Well the Real Question is were do you buy this kit????
We like to search by OE Part numbers. For this particular kit (LEXUS IS250 08.2005 - 08.2008) it would be: 04479-30151

Just go to your nearest part store and replace it. Job done.
It’s way easier putting the piston on top of the boot and blow the boot up with air through the bolt hole
Some of us don't have a compressor.
Gracias por responder ya me suscribí 😀
You never showed taking the piston out without compressor

Isn't there a special tool to expand the boot ?
@@serge4856 Looks for me an innovative way. Thanks
@@serge4856 But you forgot something 😄 There is a baste ring that will not let the air out!

Easier fix….. just replace the caliper
Cheaper fix..... Just replace the seal
