Juicy Threes brake pad service

These are hydraulic disc brakes and it's tricky to replace the pads. The system uses a non-standard bleed nipple which requires you to buy a special kit. I didn't want to go to this trouble, so here is how I replaced the pads with minimum fuss.

Firstly don't remove the bake calliper from the frame, just remove the wheel and sit the bike upside down. Don't touch the brake lever at any time during the work, other wise expect to spend an hour or so pushing the brake piston back into the cylinder.

Push a small flat head screw driver between the outside of each pad - the side that does not touch the disc. There should be a small amount of play where the pad backing plate can move. Lever the brake piston to push it back into it's cylinder - use a medium amount of force so as not to damage the piston.

Do this on both sides so both pistons give you clearance to remove the old brake pad assembly. The two pads are installed with a spring clip that separates them from the disc when the pistons are retracted, when not under braking.

You should be able to remove each pad one at a time, then the spring.

At this point you should check you piston clearance to make sure the pistons are retracted. Be very careful not to touch the brake lever when the brake is in this state.

Remove the new brake pads from the packaging and remove the protective cardboard between the pads. Holding the pads and spring together push them into the brake calliper - making sure you have them the right way around.

I helps if you remove one of the pads to let the spring and the other side fit more easily. You can then use the small screwdriver to bend the spring to let you fit the second pad behind it. Each pad will click into the calliper fitting with it's two ears.
