These two videos are good too - for general troubleshooting / fixing of this type of problem with brakes.
Ford Quick Tips #73: Quickly Diagnose a Sticking Brake Caliper w/ One Simple Test
How to Fix Sticking Brakes on Your Car
P.S. Thinking back on my issue that I had... there was also a short delay on the Passenger side front caliper / brake when pushing the brake pedal. Makes sense - as fluid flow is restricted when going IN as well as coming OUT of the caliper cylinder / piston.
It manifests itself also in this way, on the Highway at speed:
Pressing brake at highway speeds, car DID PULL a little to the left / to the center line, very briefly, as the Left / Driver side front caliper grabs first, then after hydraulic DELAY to the Right / Passenger side Caliper - then that Caliper grabs, and braking happens normally, straight ahead with NO PULL, after the short delay.
Ya, very SNAKEY and WEIRD behaviour with a partial hydraulic restriction on one front brake flex hose.
SYMPTOMS I NOTED:
VIBRATION AT SPEED (made worse by loose tie rod ends/fixed). TEMPORARY / QUICK PULL TO ONE SIDE AT SPEED THEN NORMAL after that/ ONE SIDE NOTICEBLY HOTTER THAN THE OTHER (bringing hand close to disc / wheel hub, after short drive)/ ONE SIDE OVERHEATING AND SMOKING / STINKING / BURNING A LITTLE SOMETIMES, ESP IN CITY DRIVING WHEN YOU APPLY THE BRAKES ON AND OFF MORE OFTEN / A little more DRAG on one side than the other, trying wheel drag by hand with vehicle up on stands (as described / shown in one video, wheel drag test).
[ symptoms go away with highway driving and no braking - as piston releases - as hydraulic fluid slowly flows back from wheel cylinder / piston releases - then re-occur as you apply the brakes a few times ]
Hope this helps some. The symptoms and diagnosis and fix - are very interesting ...
