Old Dog learns new trick
Coming home from work as usual. cruisin about 40 and slow for a light. Not a panic stop, just slowing and the rt front break locks and skids the tire. Now everytime I break same thing happens. I have power discs With Gm Calipers/ford discs 2lb residual built into the master cyl. The whole works has about 5K miles. Never happened til yesterday. I'm dropping the help flag.

Disc calipers don't normally stick like drum wheel cylinders do, but it's possible.
First thing I'd do though is to check the brake line on the opposite side of the one locking up, have a helper depress the pedal and look at the rubber flex line, see if it is expanding..if it is, most of the pressure bias will go to the other side and act like only one brake is working.
If the line isn't expanding, then check the caliper and make sure it is squeezing the pads.

Huh?? Frozen calipers are a common occurance especially if the vehicle doesnt get used that often.
Ive also had them lock up on a frequently driven Taurus and Volvo. In those cases the rubber boot deterioated and water got in and caused corrosion (rust)
And this is nothing new either; it happened so many times to a 66 Corvette I had (the original dual piston nightmare) that I spent the money for aftermarket stainless steel calipers.
A collapsing flex hose is also fairly common but owners dont bother changing them until something drastic occurs. I never could figure out that logic. The same with flushing the fluid periodically.

didn't get a chance to do anything today, busy trimming the house etc. but will tear things apart tomarrow. I've got new stainless hoses and renewed break lines while torn down. I will check condition of the boots and check both for travel.

I've never had a disc caliper stick (but notice I said it could happen), then again I've only had 15-20 cars over ther past 25 years with disc setups, so maybe I need more time to evaluate them.
I have had my share of drum wheel cylinders have issues, and have rebuilt too many to count.
I'd still bet caliper vs. wheel cylinder...calipers are less prone to issue....regardless, we both agree on the flex lines
