CYCOBYCO Avid Bicycle Brake Bleed Kit for All SRAM Series

This worked great to bleed the brakes on my 2019 Specialized Stump Jumper Expert 29er MTB. It comes with instructions, but actually it was easier for me to watch a few YouTube videos on how to do the process properly. Brake lever pressure is as good as new now! Way less expensive than the Specialized branded brake bleeder kit.

I've now bled 6 brakes with this kit. Results are better than I get from my local bike shop because with this kit you can use the suction from the syringes to pull all the air out of the brake fluid. All the adapters fit both SRAM and Hope brakes very well. The only issues I had were my own fault, accidentally hitting the brakes with the pads out and dropping out a piston. Watch a video or two specific to your brakes before attempting to bleed them for the first time!

Worked as planned. Only thing is that my SRAM brakes have a larger bleed port and non of the fittings would fit that hole size. I had to remove the hose and push the fluid thru the bleed port by opening just a small amount. The instruction showed a larger one for SRAM but there was not one in the pack.. The video help a lot. But it also showed a funnel that was not there either.

This kit was just like ones I saw in videos. The directions were also actually reasonable. Anyway I bled the brakes on my Santa Cruz Heckler 9 E-mtb. I think the brakes are SRAM Code R. Straightforward process if you follow the instructions carefully. Very happy with the outcome! The one wrinkle I hit: The attachment for the SRAM caliper won't fit in the opening of some brake fluid bottles. I had to use a small cup to draw from, to fill the syringe. Note this is the standard attachment for SRAM, so not unique to this kit.

Worked great for bleeding a used set of SRAM G2 RSCs. I did the front first, and the rear a few days later. When I did the rears, I was glad to see that the syringes still worked smoothly, indicating that the materials are resistant to the DOT fluid and didn't degrade. And a tip to maximize brake firmness: remove the lever-side syringe first, and the caliper (bleeding edge) side last. Push in on the bleeding-edge syringe to maximize pressure, and with the other hand, close the bleeding edge port. This maximizes the amount of fluid in the system and makes a big difference for lever firmness.

Works fine and the quality of the syringes, hoses, etc. are all decent. As others noted there are no instructions but plenty of video tutorials out there that would do a better job than any kind of written instructions. My major complaint is the the bleed blocks do not work for SRAM Guide brake calipers. They include one that works on Shimano and another that works on the older AVID calipers but not the Guide brake, as advertised. I got by using the Shimano block and shimmed it with come stiff card stock to take up the extra space. In the end it was doable but kind of annoying. At half the price of the SRAM bleed kit I guess you get what you pay for.

I thought I'd take a chance on this inexpensive kit and to my surprise the quality and functionality is terrific! I've used brake bleed kits where the syringes were SO stiff you could hardly get the fluid to flow back and forth between them (like SRAM requires) making it a real pain in the butt to bleed the brakes. My only minor complaint would be the red triangular shaped "nut" that slides onto the SRAM bleed nipple and is used to open/close the bleed port; when you attempt to push the nipple into the port and snap the needle into place the triangle simply pushes down (towards the caliper) and off the nipple, making it entirely useless. I ended up taking the assembly apart and sliding the triangle onto the nipple from the opposite end, thus making insertion much easier and withdrawal from the port a pain (but I prefer it that way). I hope that makes sense, and if you purchase one of these kits to use with SRAM brakes you'll quickly see what I mean. Overall, a terrific value I'd recommend to anyone needing a versatile brake bleed kit. One last note: if you're working with SRAM brakes buy Prestone DOT 5.1 brake fluid from any auto parts retailer, it will save you a BUNCH of $$$$'s over what you find when searching for "SRAM Fluid", which is exactly the same.

At first glance it seemed like a good kit. All the fittings work but doesn't include the proper bleed blocks for Code R brakes. Once using it the syringes don't seal tight enough and allow air into the system. When I would bleed my brakes they would end up worse that before I started. Tried using them on three different occasions and gave up and bought the Sram bleed kit and no longer had problems.
