Bleeding Shimano Hydraulic Brakes

After riding my Shimano M615 Hydraulic Brakes for a little over a month now, they were starting to feel a little spongy, mainly due to some lost fluid when I shortened the hoses so a bleed was in order.

A little research online led me to the below kit from Epic Brake Bleeding Solutions.  The kit comes with everything needed to get a good brake bleed. 

The kit includes:

  • 1x 60ml high pressure syringe & injection tubing
  • 1x 20ml locking syringe with Epic master cylinder bleed adaptor
  • 1x Length of bleed nipple/vent tubing
  • 1x Plastic bag for waste brake fluid
  • 2x cable ties
  • 1x pair of nitrile (latex free) gloves
  • 50ml Genuine Shimano Mineral Oil (SM-DB-OIL)
  • Full easy-to-follow instructions outlining the bleed process

Having completed successful and unsuccessful bleeds before I was a little concerned as to how this one would turn out.  I have however heard that Shimano brakes are pretty straightforward to bleed.  Being cautious I wanted to follow things step by step and take my time, thankfully the guys at Epic Bleed have this covered and provide this awesome step by step guide, making it almost impossible to get things wrong.

Bleeding both front and rear brakes took approx 30mins total and following the guide it went smoothly!  The brakes feel great, I'm extremely pleased and can't recommend these guys highly enough.
