'67 J50 power brakes vs. standard brakes

[Barbara S.]

I'm trying to figure out the differences, if any, between a 67 model with J50 power brakes and those with standard brakes. I see from the archives that both the J50 cars and standard brake cars use the same master cylinder. Are there any feature differences between a '67 model J50 car and a standard brake car besides the booster itself?

Thanks.

Tony------

The only other differences are the configuration of the lines from the master cylinder to the distribution block necessitated by the change in relative position of the master cylinder and the addtion of the vacuum line from the engine to power the booster. Otherwise, J-50 and standard brakes are exactly the same.

Tony,

I believe the power brake J50 option used a different pedal-hanging bracket assembly which has holes rather than studs in the lower two position to accept the captive/serrated bolts that are on the bottom two ears of the booster. Also, there's no return spring on the (J50) brake pedal, and a striker is installed on the upper hole of the brake pedal to reach the brake light switch plunger.

Jeff,
Do you know if the 66 model with PB had the striker installed on the brake pedal? The AIM does not show one.
Thanks

Dave,

Yes -- check page F349 (UPC J50, sheet A3) , items 4, 5, 6.
