CHUMXINY Brake Bleed Kit for Shimano,TEKTRO, MAGURA Range

I bought this kit for my first attempt at installing hydraulic brakes, filling the system with oil and bleeding. It includes everything you need for installing Shimano road STIs (and no doubt other systems), including the all-important little adapter that screws into the lever top before you put the cup on the top. I followed the video instructions pretty closely although each setup is a little bit different. The video could be a bit slower/more detailed but there are other videos out there that do that.

Anyway it all worked well, one 60ml bottle was enough for front and rear brakes, and I have the second bottle spare now for future bleeds. The brakes are working perfectly first time. Great value.

If it came in a tin; and the instructions were printed on that tin; it would do exactly what it says on tbe tin.

Worked perfectly on shimano SLX and Magura brakes.

Cheap and comes with all the pieces you need. Firstly, it comes with all bet bits you need to bleed the braked on Shimano Ultegra R8000 Road Brakes. You do not need to buy the Shimano adaptor.
I will share an idiots guide below in case anyone needs it.
1) Slide the brass retainer over the clear tube and push the end over the syringe. The brass ring is to hold it tight.
2) Remove the wheel, retaining pin and screw to remove the brake pads.
3) Fit the yellow brake pad in the void and re-apply the retaining screw (If the yellow block won’t fit, use something to push the pistons back then apply again).
4) Slide the tube clamp over the tube
5) Attach the hose and syringe to the bleed valve, using the 7mm spanner (included), open the bleed valve, literally 1/2 a turn.
6) Close the tube clamp and go to the lever.
7) Peel the hood back, expose the screw.
8) Using a 2mm Allen key, remove the screw and keep safe.
9) Find the yellow adaptor to fit the hole, try the larger ones first.
10) Attach the yellow funnel and 1/2 fill with oil.
11) Release the tube clamp and draw the fluid back into the syringe until there are no bubbles (you will see the fluid being drawn out of the funnel)
12) Close the bleed valve on the calliper then pump the brake lever a few times, you may see some bubbles, but until it feels firm. (Took me about 6 pumps then it was solid)
13) Push the plunger into the funnel to stop oil leaking out when you remove the assembly.
14) Carefully unscrew the yellow Cullen and adaptor, when removed re-apply the brake lever screw and tighten.
15) Clean the area of oil, isopropyl alcohol works well, or just wipe with a tissue and put the hood back.
16) Clamp the hose at the syringe, carefully remove and immediately wipe the area clean.
15) Re-assemble the brake pads and wheel etc, and enjoy your new brakes.

I cannot fault this system. I am a 1st time brake bleeder. It took 5 minutes, worked flawlessly. You don’t need any other kit, or to pay your shop 25 to do it for you.

Although this kit comes with a lot of connectors for different brake levers it does not contain the adapter needed for Shimano road brakes (GRX in my case). You’ll have to buy this adapter separately.
