When I take my foot off the pedal, the pull immediately stops, so I wouldn't think that the wheel cylinder is stuck (causing fade on the right side). Am still going to replace the cylinder and hose as long as I have the parts.

The car steers properly and the alignment was done after I replaced the king pins, tie rod ends drag link, etc. I am going to replace the right wheel cylinder and hose next. I hate to admit that I'm in this try one thing and another routine. Please keep the suggestions coming.

Alan probably gave you the best advice when he said to replace both front hoses and cylinders. When the steering wheel is jerked out of your grip when the brakes are applied, it is usually the side opposite the way the pull is that is the cause. But if one side is failing, that means the other side will follow soon. Your problem sounds like the right side wheel cylinder may not be retracing all of the way and as the fluid becomes hot it thins enough to relieve the pressure on the shoes. I would do as Alan said in his first post, rebuild or replace all four wheel cylinders, rubber hoses and thoroughly flush the brake system before you install the new parts. When you have the brakes rebuilt, flush the system every year to keep moisture from accumulating and destroying you brake system. It is hard to say how much wear the rear shoe should have in relation to the front shoe, because it provides very little braking power when going forward. It does provide most of the braking power when going backwards. My guess is the the rear shoe on the right is not adjusted as tight as the rear shoe on the left, or that the piston for the rear shoe on the right is frozen. You said that you have replaced the tie rod and drag link ends, did you center the steering wheel and make sure that your tires were straight ahead when you installed the parts? Did you have the front end adjustments checked by a front end specialist? Does the car pull to either side when driving? Keep us up to date on how it is going.

Bill, As everything appears to be normal, spin each wheel by hand to rule out wheel bearings.

I took a look at the rear brakes and they are normal. I have not mentioned that these brakes have less than 2500 miles on them and are perhaps five years old. I have owned the car for four years. This problem only began in January...All the linings have almost no wear. There is no sign of any fluid leakage on any of them. The only consistent behavior is that when they get warm the problem eases and goes away. I'm really puzzled.

You might try interchanging the front brake drums. It makes no sense to me, but I had a 74 Dodge Dart, the right rear brake started locking up when braking. I switched rear brake drums, the problem went away.

HI Brake pull old timers used Bon Ami pot scrubber, powder on the brakes., this will clean the drums and shoes, I worked for a car dealer and if we had a problem this was a quick fix. for certain applications, never had any issues doing this, we used a squeeze bulb, like the one you add water to the battery, this is good for a car that sits for long periods , you just spray it in a hole,and rotate the wheel only problem is that the V8 brakes it is hard to get on the brakes with the drums on, but the best way is to do the brakes , you have to do both sides to make it equal . hope this helps,37Ragtopman

Yes, your "warming the brakes up" causes brake fade on the most effective shoe. Doing one thing at a time, hoping to get lucky doesn't cut it. They'll never be equalized until you do right by all four wheels. Do what you'd expect a good brake shop to do. Pull all four drums, inspect & refurbish as indicated.

I replaced the wheel cylinder and hose with new parts, on the left side. Still get pull to the right, although after a number of firm stops the pull lessens and goes away. Have bled the fronts (the left a number of times) with no effect. Aldo adjusted both fronts (they were pretty good in this regard). My sense is that warming the brakes up reduces and eliminates the pull. Anyone got any ideas?
