How to Change Polaris ATV Brake Pads - Front & Rear | Partzilla.com

Get replacement brake pads for your Polaris Sportsman 850 here: bit.ly/sportsma...
Learn how to change the front and rear brake pads on your Polaris Sportsman 850 ATV. We’ll start by removing the front wheel to access the caliper, and then we’ll remove the caliper and replace the brake pads. The process is the same for both sides on the front. Then, we’ll move to the rear of the ATV. Here’s a secret: only one caliper on the back wheels and it’s on the right-hand side. Rear braking power is transmitted through that caliper and across the rear differential. So when you’re shopping, you’ll need THREE sets of brake pads, one set for right front, one for left front, and one for right rear.

Hey John Great Video! Folks are concerned that John used a screw driver to pry the pads loose. That's Ok because the piston will move back before you break the metal on the caliper. IF by chance you did break the metal, well that's not bad as it would have broke on the trail. I use a rubber mallet to get it off the disk then a C clamp. But no worries on the screw drive. Some people must work for NASA or something. Keep them coming John! Thanks T.

[@jamesmerritt132]

Great video as always, I admire this guy because he knows his stuff. The thing he left out was if you tighten that 5mm Allen nut tight it locks the brakes. You should back it off about a half turn. I’m sure because he was just doing a video and knew he would be coming back to replace rotors it was an oversight, yet if you tighten it all the way down the brakes will be tight and when put in Neutral it will be hard to move quad. No disrepair John because you at the man. I just ran into this on mine so I wanted to share. 🙌💯💥

[@phoenixatvutvclub1589]

Great video. Very informative and good camera angles to show the clearances.

[@mogyver69]

If you tighten that little allen bolt all the way in the brakes will lock up. You need to tight it up and back it off 1/4 to 1/2 turn.. I found if I pump the pedal to get the caliper to extend all the way then tighten that allen bolt and pump the brake again and then loosen that allen bolt 1/4 to 1/2 turn the rotor will rotate and my pads will not drag. Blue lock tight so you do not loosen that allen bolt.

[@robertroberts9558]

So tighten it all the way are just until tire wont spin and then back it off half turn

[@dragster5551]

you should make a video on front diff removal and install on this model. just did mine blindly removing things until it came out. it was a nightmare.

[@52Pablo]

ThanksJohn. Great video and that's why I buy parts from you folks

[@shannonludwick5738]

Awesome presentation changing mine on my 570 before are ride in may

[@upnorthvlogs]

The brake pads will go back on there. I can’t get mine to go back on there like not enough room.

[@ralphblanda661]

Great video on brake pad replacement , I own a 550 polaris 2012 touring I would like to see the cooling fan replacement as my fan bearing is pretty noisy . I purchased the new fan that is mounted on its frame .

[@ryanh1473]

Fantastic. Thankyou!

[@user-vn6bd8wg9c]

thanks

[@dunklechuck1188]

👍🏻. Can’t you fit a C clamp in there to depress the piston? Or not enough room?

[@justhunt1912]

I have a Polaris ATV 1996 xplorer 300 . I went to stop the bike did not have any breaks what could it be. the bike sits for about 6 months. thank you and I enjoyed the KZbin videos.

[@fike301]

that 5mm cap ....other people have a procedure to adjust it by tightrning until wheel wont turn than back off 1/2 turn. this i done after you pump the brake first

[@Themiscyoutuber]

How tight do the 5 mm allens go in?!

[@Caper1960]

Very helpful thanks!

any help with a 2008 caliper? mine seems to be different.

[@shaunwilkinson7855]

Is there much difference between the 850 an 550? I have a polaris sportmans 550 xp

[@Deerector]

John, I’m using a Boss plow that’s 250 pounds on my 2017 Sportsman 1000 Touring. With all the extra weight, the machine doesn’t stop as good. It’s a new machine so pads r fine. My question is, can I get better brakes, so it helps stop me better? Like maybe a brand that makes better pads or whatever really? Thoughts, opinions.....?

[@PartzillaParts]

Do you still have full pressure in the lines? Does it brake ok at first, then fade out?

[@Deerector]

Partzilla it breaks slow the entire time. But this is only when using the plow and when I’m all loaded up with my gear and stuff. When I take the plow off and gear off, brakes are fine. So I know it’s the weight of the unit. I’m operating it and the max payload. Plow is 250. I’m 190, plus other gear. It’s heavy ya know.

[@PartzillaParts]

Yeah, that's a lot of weight. You can upgrade your rotors, sintered metal severe duty brake pads and steel braided brake lines. This will all help with stopping power.

[@Deerector]

Partzilla excellent. Thank you! Will let you know how it goes!!

[@Deerector]

Partzilla just thinking....although it would be more expensive than your advice, what about if I just upgraded all 4 wheels to the brakes a Ranger has. They have two pistons doing the squeezing. I’d have to be getting much better braking than what i have now if I do that. Would this work? Would the discs fit etc?

[@owenlarsen3678]

helpful thanks

[@diegoforest]

just use channel locks to compress caliper

[@skylercolman6466]

just followed your instructions on a 2021 sportsman 550 EPS. for some reason the rear brake seems to be locked or locking, i can barely get it to move. any ideas on what might be causing this? i'm a new ATV owner and a rookie mechanic, but this is pretty straightforward. any advise would be greatly appreciated.

[@AndySCarp]

You may need to back off the allen bolt 1/4 turn or so. I'm just bout to do my brakes and there is comment that mentions the locking up issue

[@lukebenti8623]

how you fixed light on and off on my polaris 2017 sp scream

[@gregdenman2342]

I'm sorry sir, but being a mechanic myself with Dodge I would have gone with a new disc too as it may be too thin and out of specs. This could lead to numerous false brake issues such as too much lever travel etc. Just saying...

[@PartzillaParts]

We measured it. It was well within spec.

[@reddodge4423]

You know what’s a great way to rip the rubber boot is. To scrap it with a metal wire brush

[@Robbxmr]

Do you remove to res cap before squeezing the calipers?

[@gtelkey6272]

Yes, I do, just like truck brakes. Always good to see where your level is when replacing brakes and please wear safety glasses as that brake fluid will fly out when bleeding the brakes

[@Mikehancho1]

Use a c clamp Mr going back wards

[@Abclyfestyle]

Brandon Lauter I’m cringing at the screwdriver tip against the disc/new pad.

Right? Fucking kills me

[@es47]

would this be close to or the same setup as a 2015 570 sportsman?

[@PartzillaParts]

Parts will be different, but the process of doing the brakes will be the same.

What kind of grease is it? Is it any special?

[@PartzillaParts]

Just standard waterproof/hi temp grease. Lots of brands have their version. During this video we used the Kawasaki Grease: www.partzilla.com/product/kawasaki/K61021-504

A screwdriver to compress the piston? What in the hell? My 7 year old knows better

[@PartzillaParts]

Much judgment, I sense. Garage hack...I've never had anything damaged doing this. Feel free to use whatever method you're comfortable with.

[@MikeGetsItDone]

Agree, a C clamp is the perfect tool here.

[@daveanderson8537]

Ok so other than using a flat bar or wide slotted screwdriver how do suggest a “C” Clamp is going to get inside the caliber to compress that piston ??? Common sense rules here - I have used a screwdriver on many motorcycles, quads and pickups. Never had a issue !

[@NightshiftCustom]

@@daveanderson8537 you will crack/fuck up the pads using a screwdriver and even warp the rotor prying on it. then the pads don't last simple way is to use a c clamp before you put the pads in or even channel locks/ vise grips for smaller jobs. then put pads in!
