I have AVID Juicy Brake pads, the time has come to replace the front pads. The old pads are very worn. The new ones have lots of "pad" compared to the old ones, of course. I've tried to install the new ones but there is not enough room for them in the caliper.
I've tried pushing the pistons back with a screwdriver (they moved a little), swearing, shouting, pondering over cups of tea and watching You Tube on the subject.

Should I let some brake fluid out to allow the pistons to open more?

    Pushing the pistons back is the way to do it. It's a slow operation that needs lots of care to avoid damaging the pistons. There are special tools but some soft wedge tool would do the job. Screwdrivers are dangerous! – Carel Jun 12 '16 at 18:00
  • are you sure you;re swapping like-for-like pads? I mean, the pads are compatible with the callipers aren't they? – PeteH Jun 12 '16 at 19:12

    Put the old pads back in, and push them apart with a screw driver. – mattnz Jun 12 '16 at 22:30

    In my case (not Avid brakes) I have had to remove a little fluid to get new pads in place, but this was because the brake also needed bleeding. As air gets into the system the volume increases. You are trying to compress extra air when you try to pry apart the new (thicker) pads. I'd suggest trying to remove some fluid, but with the assumption you may have to add more back in when you bleed the brakes after doing this. – Lee-Man Jun 13 '16 at 18:13
