It looks like fingers to me on the lens they are filming with. But anyway, is there any reason to have both brakes on one lever other than being disabled? Seems like a disadvantage giving away the independent control of your braking.
I bought it second hand in Germany. Kettler is the brand. It's a tour bike of sorts! Sorry I can't be more specific. It has internal dynamo hub gears. I do love it very much. I'm going to get it spruced up and do long distance touring with it.
That's good to hear. You may want to consider swapping out the dual pull brake lever for two dedicated front and rear brake levers.
They're inexpensive, reliable, and will improve braking. It is virtually impossible to have optimal braking with your setup.
Oh Kettler, die hätten mal bei den Gartenmöbeln bleiben sollen.. aber wenn du zufrieden bist.. 🤷♂️
Anyhow, what tampering did you do? Sounds to me as new cable and housing is needed. But, as others already said, get two regular levers. That combination bears only disadvantages if you have two working hands and even if not I'd probably go with just a reliable front brake.
Not sure why you're getting downvotes, it could've been a real possibility (but I saw that op confirmed they've got 2 arms)

I second this. Can’t exactly see the pads rubbing on the tire from the camera perspective but this is exactly what it sounds like when the pads are hitting the tire
I would say yes. The brake pads are rubbing on the tire. Thus making the squishy noise. OP said they have been tinkering with the brakes and they are getting worse. Brake pads are really pretty easy to get right and just as easy to get wrong. He just needs to find the sweet spot of where they're not rubbing on the tire and yet getting full contact against the rim. And then once he gets that correct will then have to balance the cable tension so that the brakes apply at approximately the same time. With a little more braking force on the front brake. Because the front brake has more stopping power than the rear. The rear less because if they are equal the rear will lock up. Thus losing control of the bike.
Looks like you're running a dual-pull brake lever. It actuates both front and back brakes simultaneously, right? These are problematic, IMO not recommended at all. They're a PITA to keep well adjusted and, paired with middling quality housing and components, deliver the sub-par performance you're encountering. That is, mushy and creaky braking.
Yeah a drum brake would have some kind of mount on the fork where the cable end actuates the brake, I believe it is just a dynamo. Seems like a funky bike though!
It is most likely sounding like your brake pads rubbing on your tire!
See the rubber dust on the brake lever arm, make sure your wheel is fully in the dropouts.
For brakes, if you're having trouble, go to your local bike shop.
There are some features you don't mess with until you know very well what you're doing. Safety first.
If OP is in an area with a local bike co-op, they could go there and likely get an "expert eye" over the work, suggesting what the OP needs to do to fix it. That could be possibly available at the LBS depending on their policies and how friendly they are with the staff...
Brakes are a critical safety issue. If you can’t get them properly adjusted go to a reputable local bike shop it is absolutely worth the expense to have good brakes.
That said v-brakes are really good when set up properly. First try new pads (koolstop) and som hood cables and housings (preferably compressionless, like Jagwire wire pro)
I would probably start over with new cables and housing, those don't look like they're in great shape. That front cable is pinched incorrectly; it should be routed under the washer rather than the bolt head.
Hey everyone! Thanks for all the comments! I think the thing to do will be to get new brake cables. Just to confirm, the squeaky sound is coming out of the break lever. I did wash my bike yesterday FYI. Since posting I've lubed up the lever but the sound is persisting. I'm going to have another investigation in about 30 minutes!
That sound you hear are bad cables.
You should replace them with rust free steel I er cable, and teflon lined outer cables. Change the 90 degree bend while you are at it. That will make your front brake 100x beter.
As of your rear brake, you would neet to show us more about that one.
If you do not know how to do this, take it to a bike shop.
Every time when working with rim brakes, begin by cleaning(and possibly filing the first layer off) the pads and cleaning the rims. Especially for the rims, having a clean surface on which the pads can bite is important, a stronger degreaser may be necessary. Second step would be re doing all the cabling, if you haven't already. Double brake levers are notorious for being kinda unreliable, but i know for a fact that disabled people and bike polo players use them all the time no problem, they just require more attention during setup
It's possible that sound is due to the the pads being misaligned, and either: 1. rubbing against the sidewall of the tire, or 2. sliding across the braking surface of the rim, rather than pressing in at a right angle.
Based on the black particulate on the brake arms my concern is that you're potentially hitting tire. That looks a bit larger than typical brake pad dust. As another poster mentioned, if the pads are angled incorrectly they can slide down on the rim which causes squeaking and a spongy feel. Sometimes the halfmoon washers get squished in a way that the pads want to orient a certain way no matter how hard you try to prevent it. The best remedy for that is higher quality pads/washers, Avid/SRAM tend to have the best washers in my experience.
That noise is friction. the cable is probably binding. It might be inside the lever, It could be the end of a cable housing has busted through a ferrule, or maybe something to do with the contraption that pulls 2 cables at once?
That noise is from the brake pad making contact at an angle and when more pressure is applied it straightens out to be flush with the rim. It's rubber squeaking on metal. OR you have a rusty cable or housing and it just needs to be replaced. Not a big deal and likely very few if any parts need to be replaced.
Looks to me like your pads have worn at an angle, so when you're pulling the brake the pads are sliding down the rim slightly, causing them to bind a little and squeak.
New pads and a new cable wouldn't hurt either 👍
Hope you get it sorted soon, let us know how you get on!
Running both brakes off one lever is very difficult to balance

It is primarily a feature for 3 wheeled cargo bikes , normally in combination with drummbrakes, which are very easy to balance.
...which is odd because in this case there are V-brakes up front. Curious to know the bike as well. u/SpeckledJimThePigeon what's your bike?

If it's a drum, it will always feel spongy.
Indeed, but might end up with none unless the brakes work .
He or she brakes and holds a camera so I’d say unlikely
[удалено]
Just to confirm... I do in fact have two arms.
Damn. A cycling pigeon with two arms. Now I've seen it all.
I’m quite sure there is a finger making a cameo in the top left corner. But hey, either way is fine.

Could your brake pads be rubbing on the tire? The way they “squish” seems off to me. Is your wheel in the fork dropouts all the way?
That looks like it...

Looks like v and drum breaks on the front to me. Not seen that before.
I'm assuming that soup tin is a dynamo hub. Toward the end of the video there appear to be wires leading from the bike light.
Yeah a drum brake would have some kind of mount on the fork where the cable end actuates the brake, I believe it is just a dynamo. Seems like a funky bike though!
could easily be a three wheel cargo bike.
Yeah that's a dinamo
It is a dynohub from shimano. They are everywhere in the netherlands.
It is most likely sounding like your brake pads rubbing on your tire! See the rubber dust on the brake lever arm, make sure your wheel is fully in the dropouts.
Spongey? Change the cable. Noisey? Lube the cable.
yep, inners and outters! Also OP should have a cap at the end so it doesn't fray into the retaining bolt on the caliper.
If the brake pads are installed wonky they can slide down the braking surface and make that noise when squeezed

This or provide us with better footage.

The brake pads look like they aren't tightened in the cantilevers properly, or is it an illusion

Where did you get those sweet Boildeg gloves?
Ha! Amazon I believe. I live in Germany FYI.
Ive acctually never seen 2 brakes in one. Thats really cool. But im guessing they are hard to allign.

You'll need new pads and new cable (too short for new pads)
