Ok,,, Ive worked on a lot of cars,,, and tons of brake jobs ,,, but Im helping a friend do the brakes on his 72 Nova,,,, He's got new rotors, new calipers, new pads, and I personally helped him bleed the heck out of the system !!

The car still pulls to left for the first touch of the pedal, then it straightens out,,, then after driving on the road for a few minutes stopping & going a few times,,, the r/f caliper seems to be sticking !!

What gives ?? The only other thing i can think of is the brake line to the R/F caliper ??
Thanks for any input.

yup

It sounds like the right front brake hose is restricted.
The left front pulls momentarily because the right front hose restricted. Also the right wont release properly causing it to drag.

Ditto on the hose restriction.

When the brake pedal is applied the pressure will open the restriction (usually soft lining or kink). The return pressure is not enough to do the same.

Yup, been there, done that. Replace them both unless they're pretty new.

Thanks for the help guys,,,, it was indeed the line !! I gave my buddy some advice on how to handle the caliper during swapping pads,,,, I think he just let them hang there. : (
Amazing how something so simple can cause so much grief !!! LOL,,, !
he was angry that he changed the calipers and rotors,,, :D

Replacing calipers seems to be the common cure for a braking pull. Oh well you're in there might as well replace the hoses, no more pull. Wasn't the caliper at all, just the hose but people don't realize it and always assume caliper.
