Sorry but that is not how you adjust the brakes, that top adjuster that the cable goes through is not designed to be used to adjust the pads ( on conventional cable brakes yes ), all it is there to do is take up any cable slack that can happen over time due to the cable stretching, if you keep tightening it this way you are effectively pulling the arm up and by doing so you lose lever travel and sensitivity and due to the short travel movement the arm has you will quickly bottom out and if that happens at the wrong time well pucker up as its going to get bumpy, the correct way to adjust these retains lever travel and sensitivity and does not reduce the travel the arm has so you will never bottom out the arm travel out on the road, if you look at the arm where the cable bolts to and follow the arm to the caliper you will see a grub screw sticking out, this is basically the hydraulic piston and you basically use a tiny Allen key to turn it and the slightest of turn pushes the piston further in tightening the pads
OMG these brakes have caused me nothing but trouble on my e-bike.. your comment has helped me! The rear brake is still not right, but the front is now actually working.. Thank you VERY MUCH
Sir, Can you send me a picture on where to locate the silver screw you're referring to? And to know how to properly adjust the brake pads closer to the rotor... Thanks. 👍🚵♂️
I see someone else also mentioned the subject I'm now going to note. There's one other adjustment that can be made that you didn't mention. On the VTECH calipers there is one more adjustment that can be made. It requires a 2mm Allen wrench. There is a small Allen screw that seats against the piston that actuates the caliper pistons. Screwing the Allen screw in makes the adjustment of the brake pads tighter/closer to the rotor. Check it out.
I think your doing it the wrong way sir. The adjuster is for cable tension only like on the shifters, if you want to adjust the pads you have to tighten or turn clockwise that 2mm allen bolt without affecting the cable tension. And the spring that you put back on the pads, theres a hole on it, intended for the pin not to lose the spring (you put it in the wrong way) 🤭 Squeeze the brake lever and hold it while tightening the bolt caliper, that way tha pads will not rub to the rotor. Hope it helps.
Oh yeah looking at it I did not realize that. You know normally I don’t take the entire caliper off this might’ve been the first time I ever actually removed the spring. I really need to make the same video for the mechanical brakes I am currently working on. Thank you for watching and commenting!
Thanks for the video. I'm about to do the pads on my hydraulic brakes and from what I understand it's very similar to this, I think watching this video will prove helpful.
Steve , do any of your scooters have hydraulic oil brakes . I remember you said your hands hurt after riding a lot . One big big tip about changing pads and fiddling with the rotor is try to limit the amount of contact your fingers have with the actual surface of the pads and the rotor surface , the slightest bit of grease from you fingers will render the brake pads useless , for a while anyway, until it is burnt off . Alcohol wipes are great for cleaning the disc/rotor.
Hey man the scooters I drive have stock mechanical brakes but I am upgrading all of them to the hydraulics once I can afford it. You have a good memory my hands are still fucked up.
Oils and grease from your fingers on the pads or the rotor can also cause brake squeel. A good wipe using isopropyl alcohol on a rag before finalizing the installation should clean off any grease or oil.
Sure wish people that make technical videos would learn proper terminology when instructing how to complete the different activities in their videos. Also using the proper tools and naming the tools correctly would help as well. I see this all the time and it's like nails on a blackboard to my ears.
You should watch my recent videos with Ryan. I realized pretty early on fixing the scooters is not gonna be my strength so I teamed up with somebody that knows much more about PEVS you do you will learn a lot. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-39acIVOYNC0.html
I’m sorry that is one part of the scooter I do not know how to repair myself. Your best bet is to look on Reddit or an electric scooter forum on Facebook. Good luck with it!
Can you open up the side of the caliper to adjust the piston that pushes the brake pad? The pad still has enough thickness but when I press the brake lever after adjusting the barrel screw on the caliper as well as the barrel adjuster on the brake levers, & add some tension on the brake wires, still the brake pads couldn't grip enough to make a sudden stop....
I think your brake rotors might be on backwards here--thought the arms are meant to face forward. Hopefully not but worth having a check if there's an etched arrow on the rotor which should be pointing in the forward direction.
This video is only two years old but it feels like a lifetime ago. I have not look at the scooters for a long time I’m really only into Dualtron‘s now.
What type of brake pads are these and where to buy them? The stock m355 brakes pads are resin and they wear out in the rain super fast. Like, I have to adjust them every day and replace in few weeks, if its wet outside.
how do you reset the piston i keep pushing it but its seem to big did i bought the wrong pad they're the same size but its quite big i mean the padding is to thick
Thank you for the excellent video. I was trying to adjust my brakes and the rear wheel doesn't stop completely. The front wheel seems to stop completely after the adjustment. Is this a sign that I need to change my rear pads completely ? I've only ridden it for about 400 miles.
I just purchase this and couldn’t use it the next day. The rear brake couldn’t bite and brake. Not sure what the issue but I found my motor having some oil so is it possible the oil from the brake leak and if so is there a chance to fix it?
It’s not a good thing if there’s any oil coming from the motor. In most cases if the motor is faulty you can replace it it is not too expensive but it is a difficult job because of the wiring. Your best bet is to bring it to somebody to help you it is very difficult to learn on your own.
I’m sorry not yet I am working on a video about emove/speedway 4 clones/rebrands- if you have any questions about how to fix your brakes just let me know maybe I can help you.
I guess a seal broke on mine and Ive lost some hydraulic oil and along with that, pressure. is this common? Better to fix or just buy a new caliper please? thanks in advance
I am not really sure because these are mechanical brakes not hydraulic so no oil. You are almost always better off just replacing the cable I would imagine.
@@yogadude1234 OMG your are idiot, they do have fluid that activates the two position on the caliper. You should stop making video before you hurt someone with your lack of knowledge.
Hello, cool video. Any tip on what should I do if the little arm doesn't come back to its original position ? (same xtech brake as the one in the video)
I am not sure but I do think I know what you are talking about. Loosen the top screw. Pull the arm all the way to the right while you hold the wire tight. Re-tighten that screw while holding the wire under tension. Maybe that will get you there. Good luck and I appreciate your support!
I’m not sure what you are asking about but I don’t drive the scooter in this particular brake video anymore. I only ride Dualtrons now. I have been riding scooters for about two years and have cumulatively probably about 15,000 miles on the road. 😎
I’m not sure because I have not driven the scooter for a long time. I pretty much get all of my accessories either from MinimotorsUSA or I find them in AliExpress
@@yogadude1234 how ? this calipers are pulled by braking cable, when you pull the lever, it activate hydraulic piston. I opened it, it got red oil inside (mineral) Thank you for reply anyway. Those 2 torx bolts are holding mineral oil inside. Maybe friend gave me almost identical brake, but this he gave to me got hydraulic pistons.
Arslan 46 Wish I could help you but I’ve never worked on hydraulic brakes. Check out the Reddit forum you could probably find help there. Good luck with it!
