The brakes don't really work at all so I plan an replacing pretty much everything. Disc brakes are not on the PHS docs so I guess someone added them later. Based on the part number on the calipers they appear to be correct for a 67 GTO, along with other models in 1967.

You can get those rebuilt and keep the disc advantage. 4 piston brakes were an option for only 2 years. Quite obvious there is seized piston issues there...inner pad looks almost new and the outer is gone.

Hi GTO Mike,
If you elect to keep this added disc brake option on your ‘67 I would SS sleeve everything front to back. Four piston calipers Master cylinder Rear cylinders Check the proportioning valve that’s circled in your photo. The master cylinder is unique to 1967 disc brake as I show in the photo of the ‘67 HO I restored years ago. BTW, your WT 335 HP has the added HO exhaust manifolds which require a completely different engine wiring harness. But that’s another day. Good luck on your project.

Looks very much like the one I got from Inline tube years ago, when I swapped '67 power disc master onto my '66 Chevelle. I had a pair of '67 calipers and rotors, but sold them and went with '69 single pistons from, I think, a '69 Camaro. I don't have a good pic of it from the same angle, but I can take one, if wanted, for reference.

I had someone question me privately about my photo of the smooth rounded master cylinder on my restored ‘67 GTO that was built at the Fremont factory with power front disc brakes. Here is a New ‘67 RA from a magazine test article showing the same M/C and Proportioning valve.

My old '67 had the same style master, not sure if it was the original to the car, but the disc brakes were.
