CHUMXINY Brake Bleed Kit for SHIMANO Hydraulic Brakes, Including 300ML Mineral Oil Brake Fluid, Clear Funnel and Instruction Manual.

The CHUMXINY Brake Bleed Kit offers an excellent, cost-effective alternative to OEM or premium tools for bleeding Shimano hydraulic disc brakes. Pros: • Affordable: Significantly cheaper than kits from brands like Shimano or Park Tool. • Effective Hardware: The syringes, hoses, and fittings generally work well and are reported to be compatible with standard Shimano systems. The kit provides the necessary components for the funnel-and-syringe push/pull bleed method. • Good for Occasional Use: Perfect for the home mechanic who only bleeds their brakes a couple of times a year. Cons (with a crucial caveat): • Brake Fluid Quality: While the hardware is often reliable, the included generic mineral oil is the main point of concern. Some users recommend discarding the oil and using trusted mineral oil brands (like genuine Shimano fluid, Putoline, or Magura) instead, especially for high-performance or hard-riding applications where fluid viscosity and heat stability are critical.

Nice bit of kit at a good price. I had seen a few different videos on YouTube which show multiple ways of bleeding Shimano brakes. I decided to follow the video provided by Chumxiny in the product details on Amazon and it worked a treat. Easy to do. Both brakes are now nice and solid and not spongy anymore.

A comprehensive kit and good quality.

Great little kit.

Bought this to see if my shimano saints had air in them and a quick bleed would sort them right before a road trip! This kit worked absolutely perfectly! Had all the right adapters and fittings, fit perfectly and now my brakes feel amazing! Saved the day tbh

Followed the instructions and bleeding the system on my Voodoo mountain bike was relatively straightforward. They represent good value for money.

Good kit except for the syringe - single use and came cracked.

This is a great quality bleed kit, the bleed cup and metal fittings are of high quality and gave me a perfect bleed first time, after fitting some new hydraulic Shimanos to my son’s bike. The oil seems great and gave a nice firm bleed after having to cut and shorten hoses. Would highly recommend!
