For simple/DIY home bleeding of Shimano and similar bike disc brake systems. Compatible with mineral oil brake systems only.
Includes reservoir funnel, bung for same, 20mL syringe, plastic tube, and tube retaining clip, and instructions.
You'll also need allen/torx keys, a wrench (generally 7mm, ideally a set though), a bleed block (or something similar), and ideally to know what you're doing :D ... Generally I'd recommend not attempting to bleed your brakes unless you know what you're doing!
...But, so long as you know what you are doing, this kind of kit will make your brake bleeding experience a lot less frustrating, and likely cleaner too!
