Are your brakes squeaky at the moment? 👇

howling brakes are sometimes a benifit. Nothing gets dog walkers on a bike only trail out of your way quicker than a set of howling brakes.

I love Anna, , the sound of her voice, her knowledge, her riding... great addition to the team!!!

I solved my alignment issue, I get em dead on perfect every time.
I drilled and tapped a 3mm hole into the side of the caliper bolt post ... On both sides.
I threaded in a 3mm grub screw that adjusts alignment and lock the caliper in place.
It can't move when locking down the bolts.... Perfect every time!

Bikespeeds gives us a good analogy. Those dirty rotors with black rings.. are just like vinyl records. The grooves rotate, the brake pads make the music, our forks are speakers and our frames are.. amplifiers!

"Use your thumbs to straighten a disc" 😱 Doddy may have something to say about that 🤣

Great tips on brake issues. I could listen to Anna's voice all day long! Woo!🤘

Short, straight forward, helpful. Nice Video!

I usually just lube them up pretty good, helps with the speed as well…

I bought a new COTIC BFeMAx and the first ride the next day, the weather was terrible after about 20miles the brakes started squealing but thought nothing of it. When I got home and cleaned it, noticed the rear pads were down to the steel. That's pretty good going for 20 miles on a new bike.

My brakes squeak so loudly that the whole night wakes up when I brake 😂, but I don't do anything because I find it funny

Thanks for the video, that was a good explanation, especially the part where brakes sometimes just sweak in wet weather. A lot of people don't know this.

Aligning a caliper:
Putting the brakes on will not necessarily align the caliper... It applies the same pressure on both side pots... but if they are not centred already there is no force that will move that caliper left or right unless one pot is sticky... and then things just get worse.

So... (note: we're assuming this is a hydraulic system, not a cable one... Personally I would rather run V-Brakes over cable disk on anything other than a slow road

If you loosen the bolts and leave the brakes off, look at the back of the disk rotor where the rotors outside edge enters the caliper...
The rotor without any load on it, should be smack in the middle of the gap in the caliper body (don't confuse this with the gap between the pads as they may still be off centre)
You should find you can push the caliper left/right and lightly tighten the bolt at one end, then do the same at the other.... the result is the rotor should now be dead centre in line, right through the caliper. Check out the view at 2:52
Once done... tighten the bolts... re check the rotor is still centered (both at the front and back)... and put the brakes on a few times...

If everything is good... the rotor should barely (if at all) move when the brakes are applied, and when released - the rotor should be clear of the pads and rotors when the wheel is spun.

(This is a good time to make sure the disk isn't warped... it should not 'wobble' back n forth in the gap when the wheel is spinning).

If the disk moves sideways you may have a sticking pot (or those god awful cable brakes and you need to manually adjust the static side pad... or cable adjuster... or cable length etc... and some numpty tried to tell me cable disk needed less adjustment than hydraulic... I haven't adjusted mine hydraulic ones in 2.5 years other than fixing a sticky lever piston, and one oil change a couple of weeks ago. (And my Foes lasted nearly 20 years with a couple of changes.. and it runs Olive Oil !!!! and now has a piece of innertube as a bellows... ok u try and get 1998 Magura Gustav parts during covid.

So... did I miss anything.... Maybe that you could do a fluid change while your at it... and if your XT lever sticks in.. sanding down the piston works... as per many U-chewb vidieos.

Oh...and for glazed pads... don't forget to brake clean them as well, it may have been oil contamination that led to the heat/glazing.

If you dont have any liquid to use but for some reason have sandpaper, use the sandpaper on the pad to clear of the dirt or olie... you can also use the sandpaper on the brake disc. I did it a few times and finaly it works but ofc you do lose some of the brake pad.
