Two recent troubles with AAJ conversions I have installed.
One: my 66 300 rag. The upper caliper rod that holds the two halves of the GM caliper together, fell out. This left me with a curious "clunk" when leaving drive ways or over a speed bump. This must not have been too serious as I drove it months and miles in this condition before discovering that the 5 inch long piece was missing and NAPA has plenty of them called caliper somethings at little cost. PC photo of 76 Monte Carlo will show the part at the NAPA counter.
Two: my son's 68 Charger. With my favorite grandson and Robert leaving soccer practice, he felt something wrong in the brakes and made two circles of the parking lot whereupon the entire caliper and pads broke off the AAJ part and lodged those parts high in the wheel well making steering impossible and zero brake pedal. (Why no pedal? neither pot lost any brake fluid but the rears didn't function either) Two hours wait for AAA but all are home safe. I have a photo of the busted AAJ part with one of the two bolt holes shattered. Guessing the other of the attaching bolts had fallen out leaving the remainder to support the entire brake system. It couldn't. Thank God it didn't happen last week when he made three passes at the 1/4 mile. Mid 14's at 100 mph
Lesson learned: Probably these two main bolts must be safety wired or cotter pined. Certainly the two main bolts plus the two minor spacer bolts on the GM caliper should be inspected routinely rather than just ignored. I will be inspecting my two remaining disc conversions today and insuring the two main bolts are to be permanent party
