Issue 51 - Contains brake calipers & caliper diffusers., and has instructions for attaching the rear caliper diffusers, attaching the front and rear calipers.
Attaching the rear caliper diffusers - Gather the engine/gearbox unit and brake disc hub assemblies.
Note that the caliper diffusers are handed so take care not to mix them up.
Test-fit the left brake caliper diffuser to the left rear brake rotor holder, to identify the contact area, then apply a little ABS glue to the slot, then quickly fit the brake disc onto the shaft, ensuring you don't get any glue on it and then apply glue to the tab of the diffuser and press into place.
Ensure that the free end of the diffuser is parallel to the face of the disc, so the distances indicated in the step are the same. Then secure the diffuser with a strip of masking tape and repeat for the opposite diffuser.
Attaching the front calipers - Take the front brake units assembled in issue 12. The brake caliper parts are marked L and R for identification.
Separate the front left caliper from the sprue, taking care not to damage the plating and remove any burrs.
Test-fit the caliper to the left front brake unit to identify the contact points. Scrape the plating off al three contact points identified earlier, then apply a little ABS glue to al of them, and press the caliper into place, making sure the tabs are seated against the inner wall of the slot. Secure the caliper joint with a piece of masking tape.
Repeat the process for the right caliper.
Attaching the rear calipers - Remove the left rear caliper from the sprue and test-fit it to the brake unit in the same way as the front ones, making sure that you have removed all moulding flash from the point arrowed in the steps.
Scrape the plating off the contact points and apply a little ABS glue to all three points, then press the caliper into position, making sure the tabs are seated against the inner wall of the groove.
Secure the joints with masking tape, then repeat the process for the right rear caliper.
That's it for this week, carefully store the assemblies.
