The calipers on our cars are mounted solid to the spindle supports...no slides.
A hose can cause this problem because it can collapse on the
inside. When you press on the brake pedal, you are putting an enormouse amount of pressure thru the lines/hoses to apply the brakes. With the pedal released, there is only the design of the caliper piston seals, and the slight "wobble" of the rotor against the pads to move the pistons/pads away from the rotors. IF there is a problem with the hose, it's like a one-way valve of sorts...it allows the fluid to go thru in one direction, but not the other(at least not very quickly). Eventually, the fluid pressure built up in the hose causes the pads to just keep pressing against the rotors, causing the pull to one side, and eventually, the locking up. If it sits for a while, the residual fluid pressure will bleed back off, and the rotor will turn again.
hth....check those hoses! When something like this happens on the road, a quick test to see if that is what is causing the problem is to loosen the bleeder screw on the caliper. If fluid spits out under pressure, and the brake releases, then something is not allowing the fluid to release from the caliper. Most of the time, this is caused by bad hoses, but it can also be caused by a bad master cylinder.
