• I am having issues with a 105 hydraulic brake (front). I have bled the brake twice. I get braking force just before the lever hits the handlebars, and then lever hits bars when I squeeze. It feels like it needs a bleed, i.e. it's not a hard stop.

    I haven't yet found a way to attach a syringe/hose to suck bubbles out of the brake lines. Is there a way to do this?

    What else am I probably missing?

    Brake lever: ST-R7020
    Brake caliper: BR-R7070

  • If it's pulling to the bars even after a firm bleed, you've got a leak somewhere. I never bother with syringes for Shimano brakes, just using the funnel and tapping the caliper and hoses is usually enough to dislodge any bubbles lurking. Pushing the pistons back in with the system open also seems to get rid of anything trapped behind the piston.

  • Cable tie the brake on over night

  • Did you try the leaving the brakes on over night?
