How do you maintain your hydraulic disc brake systems, to ensure they are performing optimally? By bleeding them to remove any air bubbles and to inject new, clean fluid — and by somehow convincing a dedicated friend to hold the syringe at the rear caliper so it doesn’t fly off and spray your workspace with the DOT’s finest juice or slippery mineral oil.
Park Tool now says you don’t need to con your pal into the job. The Universal Disc Brake Bleed Kit can handle it instead. The kit includes everything you need to bleed DOT fluid brakes or mineral oil brakes, and each kit comes with a mount that holds the syringe solidly in place by attaching it to the seat stay.
