Hey everybody I ordered a sacrebird disk brake conversion bracket and then the associated parts for it and am cusrious if anybody has done one of their conversions on the 63ish Pontiac. I am looking for input on a master cylinder conversion.
Ill be installing the kit on my 63 Bonneville in the next couple weeks.

Thanks!

I will be using this one on my ‘63 Safari with the Scarebird conversion.
I’ll be running manual brakes as well.
I picked the aluminum one because I hate rusty master cylinders!
Also ended up with black Wilwood calipers to show through my 5 spoke Americans. Make sure your wheels will clear, not all 15” wheels will. I was going to use some 15” Wheel Vintiques wheels but they hit.
I have some install pics on my PC I can post maybe tomorrow if you’d like to see.

If you would be willing to share a couple pictures Id appreciate it. I am running later 15" steel wheels after the conversion so Ill be good on clearance that way. Thank you for the heads up on it.

I did one on my 62, not sure how similar a 63 is however since I know nothing about them. Guessing the booster bolts directly to the firewall like on a 62?
I also changed mine to a manual 4-spd so got a new booster, dual diaphragm for a smaller footprint, so I could put the clutch master cyl closer to the pedal assembly.
If you want the master cyl to not look bad (rust) paint it with epoxy primer.
Cupronickel hard lines are super easy to flare/bend.
