How To Check Disc Brakes - MTB Pro Tips

[@MarzNet256]

Great tips! One thing I would add is to check the caliper mounting bolts to make sure they are not loose.

[@GrecoFPV]

I just bought a cube analog 29 and the front disk brake seems that it needs a little bit of adjustments. This video helped me a lot thank you very much !!!!

[@RemingtonFoo]

You mentioned you damaged a hose while packing the bike, can you do a video on how to pack your MTB for travelling? Need to do it a couple of times this year, so a How To video would be good.

[@gmbn]

Rich Wherlock Hey Rich, We are definitely doing a edit on how to pack your bike. Keep an eye out on the channel soon. Cheers Marc

[@MrAwsomeness777]

Do you guys even ride those bikes or are they just for the videos? They are always soooooooo clean with no scratches scuffs chips, etc. You guys need to really thank your mechanics if you have them because they are doing a damn good job

[@gmbn]

MrAwsomeness777 Hey we ride them loads just really good at looking after them haha. Cheers Marc

[@MrAwsomeness777]

Global Mountain Bike Network I wish I could keep my bike like that. Can you guys maybe do a video of how to lube a bike chain. So people can see how much is enough. Btw my name is also mark

[@cxxper1751]

You mentioned Pistons sticking out with of brake I think that might be the problem with my downhill bike. The pads are pushing against the disc thank good I'm getting new brakes tomorrow

[@cxxper1751]

[@nathandaw1180]

Hey could you use brake cleaner to get oil products off your pads

[@tohhanshen2905]

gmbn can you make a video on how to fully dismantle a mechanical brake caliper since I have a problem with my brake caliper spring and I don't know how to get into it. Thanks!

[@gregorwellard349]

1:00 I got oil leaking there! what can I do? please

[@williamkeys5701]

Great video. You should do one on cable actuated brakes.

[@Markikuunn]

I use cable disc brakes, hydraulics are expensive, and I just use my bike to commute. Looking forward to install one of those, nonetheless

[@kevinhowley1586]

I find that if I sometimes get oil on my pads to fix it I go down a hill just dragging the brake. The heat burns it off. Hope that helps.

[@psych64111]

i dont have to check my bb7s, cos ive always been able to tweak or reset them quickly on the trail. fiddling about with oil.. seems like a hassle.

[@Jaxs_Detroit]

What front mud guard are you running on your bike? Love the videos keep um coming!

[@stuart3744]

I have a brand new bike with a slight rub on the disc , the tyre does not look when looking down to be completely straight, the rim is fine, someone has said that the unbalanced tyre could put a sway on the disc , what’s your opinion thanks

[@jaystarmini]

My trek 4500 d 26inch has the back disc brake on the right hand and the front disc brake on the left hand is it easy to swap them?

Clamping a bike by the Reverb dropper post? Isn't that bad to do without at least some padding on the post before clamping?

[@SamoraksTechnicVehiclesYtube]

I'm looking to upgrade the rear brake rotor on my Giant Trance 3 from 160mm to 180mm. How big of a job will this be?

[@gmbn]

+Samorak's Technic Vehicles You will need a new rotor and mount.

[@SamoraksTechnicVehiclesYtube]

[@velo1337]

can you plz do a video on the front shifter? i got hugh issues with my xt shifter since it doesnt shift under preasure (uphill)

[@zacjohnson452]

velo1337 you shouldn’t try to shift under pressure, shift BEFORE the uphill, otherwise you’ll be snapping chains left n’ right.

[@janmajnik6889]

Hi guys need a bit of help from you. Bought my first proper mountain bike, second hand (Cube Acid). Most of the bike is fine except the owner did not maintain it (if at all) but I got it really cheap so I took it. Problem is both the hydraulic brakes are shot, so they need to be bled, oil and disc pads changed. I'm not an expert since I'm new with this stuff. When I inspected the brakes at home I noticed that one brake piston on the front and both on the back do not retract properly inside when I release the lever. Also one back piston is completely not moving either in or out. My question is should I bother trying to fix them or should I scrap them and buy new brakes? Brakes are Shimano BR-M445. Thanks for the help. Appreciate it.

[@idanmashta]

Amazing channel!!

[@erickr.7041]

i have a specialized 2015 hardrock v brake...can i upgrade that bike to disk brake

[@dragosfoto]

What does the free stroke adjustment do. I have my pads to close to a 203mm disk and when I hit a bump in the road the discs hit the pads and makes a awful sound. Is free stroke a solution to the problem?

[@elidouek5438]

Well it looks like we're gonna be seeing a few maintenance videos soon, won't we Gmbn... That wasn't a question

[@antsarumae4659]

I think i got oil on my front brake disc by washing my bikes fork and mabye some oil dripped from the fork onto the disc. There is no squealing but it doesn't stop the bike at all. Is it ok to use alcoholic wipes to clean my brake disc?

[@michaelnoah3795]

Hi GMBN: I have two bikes one with Deore brakes and one with SLX brakes, after some time of riding both, when I wipe the rotors with a rag or paper towel, there always seems to be some of black stuff, once I clean them off and ride them for a while there will be black stuff on my brakes again, they are not noticeable unless you wipe the rotors with a towel then the black stuff shows on the towel, my brakes don't squeal they function perfectly. Is it leaking oil? Why are SLX and Deore both behaving that way they are mid-range brakes that should be reliable. PLEASE HELP both of these bikes are purchased within a year so if the brakes and leaking oil I can send them back to Shimano under warranty.

[@Pienimusta]

tips for getting oil off from discs if they are making noise ? ( dunno though if oil is cause of random "screams" when breaking)

[@mattgriffin6280]

Pienimusta boiling/evaporating. If you have metal or sintered pads just get a blow torch or use a gas stove and heat the face of the pads which comes into contact with the rotor and the oil should boil and evaporate off.

[@PlaidHiker]

Pienimusta rubbing alcohol

[@davitavagyan1851]

If the brake pads are good, what can cause noisy brakes when pushing the brakes harder than normal pressure?

[@logandelisle5998]

I have Avid juicy 3's and the back brake is always vibrating. The bolts are all secure though. Is this a common problem with avid brakes? How can I fix it?

[@andrewo412]

So, I just got a new bike, and when I barely tap the brakes and keep riding, with the brakes off, I am getting a bit of brake squeal. Is that just because I haven't bedded in the pads yet? or maybe one of my pistons is too far out? Thanks :)

[@gmbn]

+Spirlas bacon Sounds like you need to bedd your pads in a bit more.

[@yoshyoka]

What can I do if after a crash my caliper is out of alignment? Is there a fix or do I have to change my front fork?

[@Kbrothersracing]

how often do you change your brake pads?

[@coen8323]

Luke Kalaitzian when they wear out

[@christiancolafella656]

I just got my first dh bike and my brake levers are not activating the pistons at all. Does this mean I need oil.

[@alonbendov]

3:40 Mine arent equal how can I fix it?

[@sack1234ful]

They can be pushed in and adjusted that way. You probably already know better than me though.

[@SkyelarHead]

+Global Mountain Bike Network Is it okay to hang your bike on a bike stand from its dropper post? Also if the bike is fully carbon fiber is it okay to hang it from the frame?

[@gmbn]

+Skyelar Head just be wary of how much you clamp it!

[@SkyelarHead]

+Global Mountain Bike Network Alright I'll make sure not to clamp it to hard. Thanks for the quick response

[@sobek]

Hi GMBN. I have a question about my MTB disc brakes. The front disc brake lever has a little bit of give before it starts to brake. Is this normal or would you recommend bleeding them? Thanks in advance

[@henkdetank8401]

hello gmbn my pads arent in the middle what can i do about this problem

[@jaspreetmattu4446]

ok dont quote me on this but loosen the 2 bolts with a allen key that hold the brake calipers in place then hold down the lever and keep holding while you tighten the bolts again hope i helped.

[@JordanMaadi]

my pistons aren't returning meaning one of the pads is doing more work then the other. how do I fix this

[@J4K_Shred]

jordan maadi what you have to do is take it to a bike shop and let them check it or you can remove the pads...dont pull the leaver with the wheel of, once the pads are of use a tool (spoon, screwdriver, blunt object) and push the pistons back

[@paulcostello3207]

I have a weird wobble in my back wheel yet I can't spot what is actually bent. Any ideas?

[@Darthv298]

Both of my disc brakes make a fluid sound everytime i break. Its not actually fluid at all but sounds similar. No signs of leaks or wear. BUT need advice. Thanks

[@carswithlx]

Do you have tektro brakes?...because i have tektro brakes and they make also that weird sound,i found out that it is very common with tektro brakes because tektro cant build good rotors that always vibrate when you brake

[@DunHaveNameMeh]

May i know what is the name of that bike? or is it custom built?

[@kdippy6]

i think its a scott 700 series one (might be carbon) not entirely sure

[@kdippy6]

lol well ^

[@bitumen83]

Tapoto Meehh Scott Genius Lt 700 tuned, and yes it is carbon. It is not custom. It is around 5500 eu i think.

[@ewanbrown7466]

How do you sort the Pistons if they aren't returning

[@Batlikeman]

Ewan Brown Clean them and then just drench them in wd-40, always works. wash them after they are moving though

[@EeroSoralahti]

Ewan Brown I wasn't able to get the pistons working on my old break with any chemicals or mechanical pushing :\. Needed to buy a new caliper. Would be great to have a video on how to improvise if the usual methods just don't work.

[@NNICKKK]

Batlikeman this is terrible advice for Ewan, do NOT do this- WD40 shouldn't be used anywhere near a brake-and certainly not for this problem. WD40 is a light oil based product that may introduce contaminated material into the calliper and more importantly you risk contaminating the rotor and pad. A calliper should be properly inspected and serviced if needed. With the pads REMOVED before inspection, a stuck piston can be coaxed back with light pressure from a plastic tyre lever or a drop of the brake fluid applied carefully around the piston. That might free up the piston. If its sticking badly and seems 'dry' then it probably needs serviced/stripped. Most good bike stores will do this if you lack confidence or the tools.

[@NNICKKK]

***** correct :) just not the WD40...never the WD...

[@prakadot]

i think i have problem with my caliper adapter. it make my caliper not right in the center of the rotor. when i screw my caliper in,it bend to one side. i try to make the caliper right in center before screw it in. but it doesnt work

[@ilikerealflight]

+Prakasa Aditya I realize this is a late rply but it is possible that is you have cable disk breaks that only one pad moves. That's the way my brakes work. So when you break the one pad kinda pushes the rotor over to the other pad and slows you down that way. There should be a screw on the stationary pad. Adjust that slightly and the pad should move away from the rotor

[@fernandonogueira2291]

Hey guys, hail to the show and yourselves!! Our saviors from mechanical issues! So, the pads on my rear brake are not fully touching the rotor. They´re are more or less using half of the width of the rotor. What could be causing that?

[@gurpreetladhroyia1998]

i have change brake pads but its not working. levers r full pulled but my cycle not stop

[@kfkosz]

Can anyone help me with this a problem I'm having with my brakes.. After a long ride in very wet conditions, I got home and rinsed my bike off. The next day when I wanted to do a full clean I noticed my rear brake lever was not returning and the pistons were pushed out so that the wheel wasn't spinning. I took the wheel off, pushed the pistons back in and replaced the pads. When I put the wheel back on, the brake lever went all the way to the handlebars and the pistons don't push out and the lever doesn't work at all. I have Shimano M500 brake levers and the brake is Shimano MT-500.

[@hardtail_reapers_mtb8014]

Did you ever figured out the issue? I have the same brake system and mine feel spongy even after multiple brake bleeds and new brake pads.

[@kfkosz]

@@hardtail_reapers_mtb8014 I tried a bunch of different things but the only thing that worked was when I replaced the brake lever with a new one 🤷

how to fix disc brakes slips

[@wangmauler]

"Disc brakes are all slightly different depending on the brand and model but all work on the same principle," Is this guy for real? All mountain bike disc brakes have hydraulic fluid? should change the title and mention that this mostly does not apply to non-hydraulic fluid disc brakes.

[@gmbn]

wangmauler Sorry I should have said this applies to hydraulic disc brakes, but that is the majority of disc brakes used on Mountain Bikes. Neil

[@PlaidHiker]

wangmauler mechs are normally used on lower quality bikes, bikes you wouldn't generally want to do much actual mountain biking on.
