Dragging Brake? Pulling all over the place.
Here's the deal: my 1970 with manual brakes has a mean pull to the right when getting on the brakes, and when you let off it pulls to the left. Today I think a caliper stuck a bit because it continued to pull left for a bit until I got on the brakes again. After that, was fine while driving but kept the pull to the right when braking and then pull to the left on release. Makes for quite the ride. I'm going to pull the wheels off and have a look, any thoughts before I start? No evidence of leaks so far, master is full.

Well, toward the end of my last little jaunt before I changed out the rubber lines, the right rear caliper was starting to smoke. The right side was progressively pulling to the right until I could get 'er pulled over.
There have been many guys here say old rubber lines can collapse and prevent fluid from backing out of the caliper. I just replaced all four hoses after that incident. Not a problem since.

I had a look at my hoses and they look ok, no obvious deterioration or damage to report on sight.
Is there something I should look for? I squeezed them and they felt a little stiff.

it happens inside, not outside. You can not see the problem, sometimes they will feel soft when squeezed, sometimes not. I put flex-able stainless on mine. I had a good rubber one blow apart when auto-crossing once. It was not an original hose, been replaced when did brakes.

I had the same issue. With the wheels off you could see one side was not making full contact with the rotor.
I replaced all four calipers and new brakes lines and all is right again. New pads too.

I will order the hoses today and get going on that. Stainless is a no brainer? The car sits a lot.
I will leave the calipers alone until the hoses are done I guess. Any way to check for a sticking caliper with them on the car? I have a squeak at times when driving, it is clearly a brake sticking...but sounds like I should try the hoses first? No evidence of leaks. Thanks.

Left front hose was definitely the problem, when I took it off I couldn't blow any air through it all...zero. The right one wasn't much better. Replaced both front hoses and hoping to do the rears this weekend if they show up at the parts shop (had fronts in stock, not rears). Fronts obviously made a huge difference, looking forward to getting the rears on. Calipers and pads on the front looked good, so I left them alone. Thanks for the help, was a pretty straight forward job and I enjoyed it..
