Igofar sent me a whole load of pictures of different SMC units that have crossed his work bench this month.
I think he knows me well enough by now to realise that this is like a birthday present to me, but said I could post them if I wished.
Well - yes - I reckon anything that helps others to know what to do - or in this case, what not to do - is well worth posting. Click the thumbnails to get a 1024x768 image.
So the first photos shows the offending SMC units. These must have been cleaned up - I have a brand new one on my desk here, and it doesn't look as clean and sparkly as these !
The rest of the text is from Larry:
Photos 2, 3, and 4 are of a recent bike that had 90,000 miles on it, the piston is so jammed in the bore, I could not even move it with a punch and ballpeen hammer!
Photos 5, 6, and 7 are interesting….the lower mounting bolt (6 mm head allen) that secures the unit to the fork lower, was loose and backing out, allowing the rotor to start cutting away at the bracket! The owner said he could hear something, but was not sure was it was, and thought it was normal tire noise lol.
Photos 8 and 9 are my favorite, the guy said his brakes would start dragging, so he'd stop, open the saddlebag, and retrieve a ballpeen hammer and a brass drift punch and whack it a few times to free it up!!!
If you enlarge the pictures, you'll see CRACKS in the unit from his method!
Cheers Larry.
