Restoration / 1969 Camaro Front Power Disc / Rear Drum Brake Clips
« on: June 21, 2020, 05:09:23 AM »
I just completed the restoration of the brake clips for my 1969 RS Z/28 Project. My research lead me to a few, incomplete threads on CRG so I thought I would contribute a comprehensive reference thread in case others can benefit from this information in future. All clips shown are original and restored, none are reproduction. All bolts are manganese phosphated and as there are several threads on CRG that discuss where to source phosphating solution and how to convert fasteners I won't address that process.The black chromate fasteners (3 - double hoop style) are first clear (silver) zinc plated followed by a black chromate immersion solution. The result is similar to low-gloss black paint however more durable and it doesn't flake or chip. The finish is also similar to Black Oxide immersion solution (which does not require zinc plating) and both are available from electroplating suppliers like Caswell. For the semi-transparent blue and green clips I used Steel F/X metal solvent dye. Its best to apply it with a low pressure air brush. It dries quickly and produces a fairly durable flat sheen finish. I applied two light coats. I've include a color coded (by clip) reference from the AIM as well as photos I took at MCACN of some original cars with undisturbed clips to show the location and orientation of each clip.
