XP-R-T Disc Brake questions

[addo]

Posted here seeing as they differ somewhat to the US incarnations.

I am dismantling my XP discs for repainting and have noticed something of interest.

What I thought was originally casual damage to the dust shields, appears to be deliberate bending out from the disc. Taking the inspection a step further suggests this has been done to increase airflow over the brakes.

Anyone know if this was part of a TSB?

Also, I have an XR/XT spindle in which the dust shield has apparently been cut down in production (too neat for a hack and has shear marks on the edge). Would this be off a GT? I ask because the XW/Y GTs had a deleted dust shield.

Looking for pointers to what Ford were thinking and doing, so I can choose a path.

Thanks, Adam.

Note how neat the edge of the trimmed one is. As usual, click the photo for original image size.


The tweak downward is quite pronounced.


Ideas? I'm lost. Ford did have some rough remedies in their TSBs; my fave is the way they blew oxy holes in the shock towers, for grease fittings on the upper arms of XR/ZA suspensions. I can imagine issue 1 on the brakes said "Bend the dust shield out ½ inch"; issue 2 saying "Fit the revised shield plate" or somesuch.

Ford's legalised butchery!

Love the idea. Perhaps the stones and gibbers were getting lodged in between the covers and discs?

I'll have to talk to Dunedin City Fords parts guru. He's old enough to know!
