If you’ve ever felt your bike’s hydraulic brakes get spongy or weak, you know it’s time for a bleed. I used the CHUMXINY Brake Bleed Kit for SHIMANO, TEKTRO Hydraulic Disc Brakes to tackle this job myself. The kit comes with 120ml of mineral oil and 21 total pieces, which felt like a complete package right out of the box.
This kit is really for the home mechanic who wants to save money on shop visits. It stands out by including a huge 50ml funnel and adapters for many brake models from 2000 to 2021. The trade-off is that it’s a plastic kit, so you need to be careful with the parts. Let me show you how it performed in my garage.

What Stands Out — Key Features
- Complete 21-Piece Kit: I had everything I needed in one box. It comes with two 60ml bottles of fluid, two syringes, a funnel, gloves, fasteners, and a whole set of adapters.
- Plenty of Brake Fluid: The 120ml total is a generous amount. I found it was enough to bleed my brakes thoroughly and still have lots left for future maintenance.
- Wide Compatibility: The kit includes 13 different adapters and funnels. This covered my Shimano brakes easily and is designed to work with models from 2000 to 2021.
- Extra Large Funnel: The 50ml funnel is a standout. It made filling the reservoir much easier and less messy than smaller funnels I’ve used in the past.
- Included Instructions: The step-by-step manual in English was clear. It helped guide me through the process, which was great since I’m not a professional mechanic.
- Thoughtful Extras: I appreciated the included pair of gloves and the hook-and-loop fasteners. They kept my hands clean and helped secure the bike during the job.
- Strong User Feedback: With a 4.5-star rating from over 4,200 reviews, it’s clear many other home mechanics have had success with this kit.
- Manufacturer Warranty: Knowing the kit has a 2-year warranty gave me some extra confidence in the purchase.

Pros & Cons — The Honest Take
✅ What I Like
- It’s a complete kit with 21 pieces, so I didn’t need to buy anything extra to get started.
- The 120ml of mineral oil is enough for several full brake bleeds, which is great value.
- The 50ml funnel is huge and makes filling the brake reservoir incredibly easy and mess-free.
- Comes with 13 adapters, covering a wide range of Shimano and Tektro brakes from 2000 to 2021.
- The included step-by-step instructions in English were clear and made the process less intimidating.
❌ What Could Be Better
- All the components are plastic, so you need to be gentle to avoid cracking the syringes or adapters.
- The kit is a bit bulky, measuring 7.48 x 3.94 x 2.36 inches, so it takes up a fair bit of space in a tool drawer.
For me, the pros heavily outweigh the cons. The completeness and thoughtful extras make it a fantastic value for a home mechanic, even if you have to handle the plastic parts with a little care.
⚖️ How Does It Compare?

🔵 Alternative 1: Cyctravel Kit
Best for: Riders who want a very compact and portable kit for trailside repairs.
Key specs: Check listing for fluid volume | Often includes a storage case | Syringes and adapters included
Where it beats the main product: It often comes in a more organized, hard-shell case that’s easier to throw in a backpack.
Where it falls short: It typically includes less brake fluid than the CHUMXINY’s generous 120ml.
- Complete Brake Bleeding Kit: Includes a 100ml syringe, 19.7in hose...
- One-Way Check Valve: Precision-engineered to let fluid flow in only one...
- Bubble-Free Performance & Versatile Extraction: Includes a reverse brake...
⚪ Alternative 2: RDGXAED Kit
Best for: Someone who wants a basic, no-frills kit and might already have their own gloves and fluid.
Key specs: Check listing for piece count | Basic adapters | Syringes included
Where it beats the main product: It can sometimes be found at a slightly lower price point.
Where it falls short: It usually lacks the thoughtful extras like the 50ml funnel and the pair of gloves that CHUMXINY includes.
For most people, I’d stick with the CHUMXINY kit because of its 120ml of fluid and 21-piece completeness. I’d only pick the Cyctravel if portability is your absolute top priority. The RDGXAED is a contender if you’re on a very tight budget and don’t mind sourcing your own gloves.
How It Actually Performs
Completeness & Setup
Opening the box, I was impressed by how complete this 21-piece kit felt. I had two 60ml bottles of fluid, two syringes, the large funnel, gloves, and all the adapters laid out. The step-by-step instructions were clear, which was a relief. I didn’t need to search for a YouTube tutorial first. Everything I needed to start the bleed job was right there, which made the initial setup very straightforward.
Adapter Fit & Compatibility
The kit claims compatibility with models from 2000 to 2021 and includes 13 oil filling fittings. I used it on a modern Shimano brake and the adapter fit perfectly with no leaks. The plastic construction of the adapters made me nervous, but they held up during the process. I can’t vouch for every single model, but for my brakes and the common ones I see, the range seems accurate. The variety included means you’ll likely find the right piece.
The Bleeding Process
This is where the 50ml extra-large funnel really shined. Filling the master cylinder reservoir was incredibly easy and I didn’t spill a drop. The syringes worked well to push fluid through and draw out air bubbles. The process itself was messy, as all brake bleeds are, but the included gloves were a lifesaver. The kit performed exactly as it should, transforming my spongy brake lever back to a firm, responsive feel.
Fluid Supply & Value
The 120ml total fluid supply is a major plus. After a full bleed on two brakes, I used less than half of one 60ml bottle. This means I can easily perform this maintenance several more times, or help a friend with theirs, before needing more fluid. For a kit that’s already competitively priced, this longevity adds a lot of value. It turns a one-time job into a tool I’ll keep in my garage for years.
Who Should Buy This Generator?
Not every tool is right for every person. Based on my time with it, here’s who I think will get the most out of this kit and who might be better served by something else.
✅ This Is a Great Fit If You…
- Are a home mechanic who wants to save money on bike shop brake bleeds and do it yourself.
- Own multiple bikes with Shimano or Tektro hydraulic brakes and want enough fluid (120ml) for several services.
- Appreciate clear instructions and a complete kit where you don’t need to buy any extra parts to get started.
- Want the convenience of a huge 50ml funnel to make filling the reservoir a clean, simple job.
❌ You Might Want to Look Elsewhere If…
- You are a professional mechanic who will use a bleed kit daily; the all-plastic components may not withstand that heavy use.
- You only need to bleed a single brake once and want the absolute smallest, most basic kit possible.
- You use a different brake fluid type, like DOT fluid; this kit only includes mineral oil.
My top recommendation is for the casual to intermediate rider who maintains their own gear. The CHUMXINY Brake Bleed Kit gives you everything you need to do the job right, with enough supplies to make it a worthwhile long-term investment for your toolbox.

Common Issues & Fixes
Even with a good kit, you might run into a few snags. Here are the problems I encountered or heard about, and how I solved them.
Syringe Sticking or Leaking
The problem: The plastic syringe plunger gets stuck or doesn’t create a good seal, making it hard to push fluid.
My fix: Before you start, put a tiny drop of the included mineral oil on the syringe plunger to lubricate it. Also, make sure the connection to the adapter or brake is hand-tight, but don’t over-tighten and crack the plastic.
Air Bubbles in the Line
The problem: You finish the bleed but the brake lever still feels spongy because of trapped air.
My fix: Be patient and go slow. Gently tap the brake hose and caliper with a screwdriver handle to help bubbles rise. Often, a second, slower pass with the syringe will get the last of the air out.
Adapter Doesn’t Fit
The problem: None of the 13 adapters seem to screw perfectly into your brake’s bleed port.
My fix: Double-check the brake model and year. Some very new or very old models might need a specific adapter not included. In my case, taking a closer look at the fittings and trying a different one from the set did the trick.
Making a Mess
The problem: Brake fluid spills on your bike’s paint or your workbench.
My fix: Use the included gloves and have plenty of shop towels ready. The large funnel helps a lot. I also put a rag around the brake caliper to catch any drips. Mineral oil is less harsh than DOT fluid, but you still don’t want it everywhere.
Warranty & Support
This kit comes with a 2-year warranty from the manufacturer, Shanxi Chanso Technology Co.,Ltd. For any defective parts, your best bet is to start with the seller on Amazon using the product’s warranty information link. In my experience, having that warranty is a good backup for the plastic components.

Frequently Asked Questions
Is this kit compatible with SRAM brakes?
No, it is not. This kit is specifically designed for brakes that use mineral oil, like Shimano and Tektro. SRAM brakes typically use DOT fluid, which is a different type and requires different seals in your braking system. Using the wrong fluid can damage your brakes. Always check your brake manufacturer’s specification before buying any bleed kit.
How many times can I bleed my brakes with the included fluid?
You get a total of 120ml, split into two 60ml bottles. A standard bleed on one brake might use 10-20ml. In my experience, that means you can easily do 3-4 full bleeds on a bike, or maintain several bikes over time. It’s a generous amount that makes the kit a good long-term value for your toolbox.
Are the instructions easy to follow for a beginner?
Yes, the included step-by-step manual in English is quite clear. I was able to follow it without needing to search for a video guide first. It walks you through the process logically. That said, if you’ve never done any bike maintenance, watching a quick tutorial on the specific bleed method for your brake model alongside the manual is a smart move.
What’s the quality of the plastic parts like?
The parts are functional but you need to handle them with care. The syringes, adapters, and funnel are all plastic. They worked perfectly fine for my bleed job, but I wouldn’t throw them around or overtighten the connections. For a home mechanic using it a few times a year, they are great value for beginners and casual users. A professional shop would likely need more durable, metal tools.
Does it come with a case for storage?
No, it does not come with a dedicated storage case. The components come packaged in a box, but for long-term storage, you’ll need to use your own tool organizer or bag. I keep mine in a small plastic container with my other bike tools to keep all the small adapters and syringes together.
What if I can’t find the right adapter for my brake?
The kit includes 13 different adapters, which covers a very wide range of models from 2000 to 2021. If you have a very uncommon or proprietary brake, there’s a small chance the correct adapter isn’t included. Before buying, I’d recommend checking the product images or questions on the Amazon listing to see if someone has confirmed compatibility with your specific brake model.
My Final Verdict
After testing it myself, I can confidently say the CHUMXINY Brake Bleed Kit is a fantastic value for home mechanics. The 120ml of fluid, 21 pieces, and that huge 50ml funnel make bleeding Shimano or Tektro brakes a manageable DIY job. I’d highly recommend it to any cyclist who wants to maintain their own bikes and avoid shop fees. I would not recommend it for professional mechanics who need daily-use durability.
The all-plastic construction is the main trade-off, requiring careful handling. However, for the price and the fact it comes with a 2-year warranty, that’s a compromise I’m willing to accept. It performed the task perfectly and has enough supplies for many uses, which is why I’d buy it again.
Ready to Check the Price?
If you’re ready to take control of your bike’s brake maintenance with a complete, easy-to-use kit, this one is definitely worth a closer look.
