When I recently renewed all the front suspension arms I noted that the front disc shields were aluminium and was happy to see that they weren't horrible and rusting like the rears.

Today I took the discs off to renew them as part of the complete brake overhaul and found that both left and right shields had suffered galvanic/electorlytic corrosion where the contact the front knuckles.

My repair was to sandwich the shield between 2 M6 repair washers. This pushes the shield about 1mm closer to the disc but there is planty of clearance still.

If they had completely cracked through there is a potential for catching, rotating and severing a brake flexi.
More likely it would drop and make a horrible noise.

I think most of us will have done this at some point. Did mine last year as you describe - sorted!  The older I get, the more I realise that people confuse wrinkles for wisdom

What you described about a potential disc shield failure actually happend to me while driving through Muswell Hill on a saturday morning in my 82' 4 door classic.
It started with a high pitch grating sound (i thought it was a trapped stone), got louder and louder with crowds at bus stops looking round. I tried to sit al low as possible in my seat (not me honest). then there was a huge bang and silence. the car behind flashed his lights, looking in my mirror I saw the disc shield up against the kerb. the car seemed ok and the brakes felt fine brakes so kept going in the heavy traffic, checked everything back home, I was lucky no damage was done.

Mine rotted and started making an evil noise.
20 minutes later and both removed. Never refitted them. Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"
