Screen captures from the completed object-tracking augmented contextual instruction user experience. The augmented contextual instruction is made up of a sequence of junaio channels that can be browsed in the junaio AR browser. For this example, the channels were browsed using junaio on an iPad.
Place the assembled rear brake caliper on the workbench with the retaining bolts facing towards you.The first step in disassembling a rear brake caliper is to remove the bracket from the caliper. Use a spanner to loosen the retaining bolts.Remove the bracket from the caliper and then place the bracket on the workbench facing towards you.The second step in disassembling a rear brake caliper is to inspect and clean the retaining bolts and remove the rubber seal from the bracket.Put the bracket to one side. Place the caliper upside down on the workbench with the inlet port facing away from you.Insert the air tool into the fluid inlet port of the caliper.Turn the caliper over with the cylinder bore facing towards you.Use a pointed tool to remove the piston seal from the caliper.You have now completed the final step in disassembling a rear brake caliper. Remember to inspect and clean all parts before reassembly.
Rear brake caliper placed in the correct position for Step 1: Remove bracket from brake caliper.
Bracket placed in correct position for Step 2: Inspect and clean retaining bolts.
Brake caliper placed in correct position for Step 3: Remove piston from brake caliper.
Caliper placed in correct position for Step 4: Remove piston seal from brake caliper.
Preparing low-poly geometry for augmented contextual instruction in the disassembly and assembly of a vehicle’s rear brake caliper. Augmented contextual instruction is to be prepared in Metaio Creator, published to a Metaio channel and then accessed by learners through the Junaio app. 3D point cloud data is gathered with Metaio Toolbox.
This video conceptualises one stage of the disassembly of a brake caliper.
Using Metaio Toolbox to map the brake caliper and create a 3D point cloud.
Brake caliper with components in partial disassembly.
Three components that make up the brake caliper.

Roughly storyboarding the brake caliper disassembly process. Arrows show direction and movement of the point of interest.
Once the piston has been loosened, it rubber boot can be removed from the brake caliper.
[Edit: Tuesday 13 August 2013] This video incorrectly conceptualises one part of the brake caliper disassembly process. A screwdriver is not used to extract the piston, seal and rubber boot from the caliper.
