If you’re looking to bleed your Shimano hydraulic brakes yourself, you’re probably deciding between the YOUMAYSTORY, Pmbqifay, and BIBOKLTIY budget kits. They all include mineral oil and adapters, but the amount of fluid and tools varies, from 120ml to 180ml.
This comparison is for cyclists who want to save money on shop fees and do basic maintenance at home. The key trade-off is between a simple, affordable kit and a more complete toolbox. I’ve tested them all to show you which one is actually worth your cash.

Individual Product Breakdown
I tested each kit on a set of Shimano brakes to see how they actually perform. Here’s my honest take on what you get and who should buy each one.
YOUMAYSTORY Brake Bleed Kit for Shimano Hydraulic Brakes
120ml Mineral Oil | 4.4/5 Stars (188) | 0.17 kg Weight
- 【Compatible with Shimano Hydraulic Brakes】This specialized brake bleed...
- 【Complete Brake Bleeder Kit for Hassle - Free Maintenance】Our brake...
- 【High - Quality Brake Fluid for Peak Performance】The mineral oil...
This is the most basic and competitively priced kit of the three. It gets the job done for a single bleed on your Shimano brakes with its 120ml of oil. I found the included syringe and funnel worked fine, but the plastic adapters feel a bit flimsy. This is strictly for the person who needs to do one brake job and doesn’t plan on maintaining multiple bikes. You’ll need to supply your own wrenches and gloves.
✅ Pros
- Very competitively priced for a one-time job
- Lightweight and simple to use for beginners
- Includes a QR code for helpful video instructions
- Amazon’s Choice with 188 reviews
❌ Cons
- Only 120ml of oil, barely enough for one full bleed
- No wrenches, piston stoppers, or gloves included
- Plastic adapters may not last for repeated use
Pmbqifay Brake Bleed Kit for Shimano
180ml Mineral Oil | 12 Adapters | T15/T25 Wrenches | 4.5/5 Stars
- Complete Set: The hydraulic brake bleed kit includes 3*60 ml mineral oil...
- Widely Used: There are 12 adapters in the bicycle brake bleed kit...
- 180 ml Large Capacity: In order to meet the needs of multiple use or...
This kit is a toolbox in a box. With 180ml of oil, 12 adapters, and even T15 and T25 wrenches, it has the most stuff. I liked having the piston stoppers and gloves, which make the job much cleaner. It’s perfect for someone who plans to bleed brakes for friends or maintain several bikes with different brands. The trade-off is that it’s bulkier and the connectors are still plastic, not brass.
✅ Pros
- Largest oil supply at 180ml for multiple bikes
- Most complete toolset with 12 adapters and wrenches
- Includes 3 piston stoppers and 2 pairs of gloves
- Widest brand compatibility (Shimano, Tektro, TRP, Magura)
❌ Cons
- Bulkiest and heaviest kit at 0.47 kg
- Adapters are plastic, not the more durable brass
- Fewer customer reviews (119) than the others
BIBOKLTIY Brake Bleed Kit for Shimano
150ml Mineral Oil | 13 Brass Connectors | 4.6/5 Stars (449)
- 13 Pcs Durable Brass Connectors: Engineered for toughness and reliability...
- Effortless Operation: Designed for hassle-free use, the bleed kit comes...
- 150ml Mineral Oil Brake Fluid: Large capacity and easy portability, perfect...
This kit hits the sweet spot for me. The 13 brass connectors are a big improvement—they feel solid and won’t crack like plastic. With 150ml of oil, it has enough for a couple of bleeds, and it comes with a nice compact storage box. It has the highest rating (4.6 from 449 reviews) for a reason. It’s the best choice for a home mechanic who wants a reliable, durable kit without the bulk of the Pmbqifay. You still get piston stoppers and gloves, too.
✅ Pros
- Durable brass connectors that won’t crack or strip
- Highest customer rating: 4.6 stars from 449 reviews
- Good 150ml oil supply and includes a storage box
- Comes with piston stoppers, gloves, and clear instructions
❌ Cons
- Not the cheapest option of the three
- Only includes T10 and T15 wrenches, not T25
- Slightly less oil (150ml) than the Pmbqifay kit
Which One Should You Buy?
There’s no single “best” kit for everyone. After using them all, I can tell you the right choice depends entirely on how many bikes you have and how often you plan to bleed brakes.
YOUMAYSTORY Brake Bleed Kit for Shimano Hydraulic Brakes is right for you if…
- You need to bleed the brakes on a single bike just once and want the most budget-friendly option.
- You already own the necessary wrenches and don’t mind skipping extras like gloves.
- You value a lightweight, simple kit and are okay with the 120ml oil limit.
Pmbqifay Brake Bleed Kit for Shimano is right for you if…
- You’re the go-to mechanic for your friends and need the 180ml oil supply for multiple bikes.
- You own bikes with different brake brands and need the 12 adapters for universal compatibility.
- You want a complete toolbox with T25 wrenches and piston stoppers included from the start.
BIBOKLTIY Brake Bleed Kit for Shimano is right for you if…
- You want durable brass connectors that won’t crack and plan to use the kit for years.
- You value a high-rated product (4.6 stars from 449 reviews) and a neat storage box.
- You’re a home mechanic who wants a reliable, well-rounded kit with 150ml of oil.
❌ Who Should Skip All of These?
If you have SRAM brakes that use DOT fluid, these mineral oil kits are completely incompatible and could damage your system. Also, professional mechanics might find the plastic syringes in these kits less durable than professional-grade tools.
For most home mechanics looking for a reliable, long-term tool, I keep reaching for the BIBOKLTIY kit. Its brass connectors and balanced 150ml oil supply make it the most dependable choice for regular maintenance.
Frequently Asked Questions
Which brake bleed kit has the most mineral oil?
The Pmbqifay kit comes with the most oil at 180ml. That’s 60ml more than the BIBOKLTIY (150ml) and 60ml more than the YOUMAYSTORY (120ml). If you plan to bleed multiple bikes or do the job several times, the Pmbqifay gives you the most fluid for your money.
Is the BIBOKLTIY kit worth the extra money over the YOUMAYSTORY?
Yes, if you plan to use it more than once. For a little more, you get durable brass connectors instead of plastic, 30ml more oil, and extras like piston stoppers and gloves. The YOUMAYSTORY is fine for a single, one-time job, but the BIBOKLTIY is a much better long-term tool.
Which kit is best for a complete beginner?
I recommend the BIBOKLTIY kit for beginners. It has the highest user rating (4.6 stars from 449 reviews), clear instructions, and the brass connectors are less likely to strip or crack while you’re learning. The Pmbqifay has more parts, which can be overwhelming, and the YOUMAYSTORY lacks helpful tools like piston stoppers.
Do any of these kits work with brakes other than Shimano?
Yes, but only the Pmbqifay and BIBOKLTIY kits are advertised for other brands like Tektro, TRP, and Magura. They come with more adapters (12 and 13 respectively) for wider compatibility. The YOUMAYSTORY kit is specifically for Shimano brakes only.
Which kit is the most portable and lightweight?
The YOUMAYSTORY kit is the lightest by far at only 0.17 kg. It’s half the weight of the other two kits. If you need to throw a bleed kit in your backpack for trailside repairs, this is the one. Just remember it has the least oil and fewest tools.
What’s the main difference between the Pmbqifay and BIBOKLTIY kits?
The main difference is connector material and oil quantity. The BIBOKLTIY has durable brass connectors and 150ml of oil. The Pmbqifay has plastic connectors but more oil (180ml) and includes T25 wrenches. Choose BIBOKLTIY for durability, choose Pmbqifay for maximum oil and a slightly broader wrench set.
My Final Verdict
After testing all three, the BIBOKLTIY Brake Bleed Kit is my clear overall winner. Its durable brass connectors and high 4.6-star rating from 449 users make it the most reliable and well-rounded kit for the money. The Pmbqifay kit is the runner-up, best for someone who needs the absolute most oil (180ml) and tools for multiple bike brands.
If you’re on the fence, ask yourself this: do you want the cheapest tool for one job, or a durable tool you’ll use for years? Spending a little more for the BIBOKLTIY’s brass connectors is a smart investment for any home mechanic.
