67 122 Dual Circuit brake conversion

Post by **britfettle** » 18 Nov 2011, 08:48

The Single circuit brake master cylinder that came out of my '67 car had the activation rod/yolk attached to the cylinder -- which oriented the brake pedal for adjustment. The new dual circuit master (including adapter) has an activation rod which is not attached to the cylinder bore and just sort of floats there -- making it impossible to use this new rod to position the pedal as before. The only solution I can think of to orient the brake pedal in its proper place is to fabricate some sort of pedal stopping bracket inside the footwell -- which seems unfortunate. Has anyone encountered this problem? I could possibly take the seals from the new cylinder and rebuild one of my parts '68 brake master cylinders (dual and no adapter needed) if the bores were the same. Thanks, Stephen

Hi
You remove the circlip holding the original push rod in place and transfer it and the retaining washer over to the new master cylinder. Presuming you are using the same bore size cylinders
