Right Front Brake is Locked Up
#1

I have been searching threads the last two nights. Have read lots of threads and havent found an answer. I Had the front wheels off and the truck on jack stands. Noticed the hard line on the front pass side was wet. I wiggled it and it snapped. Replaced that hard line. Have bled the brakes at all four corners, several times. I'm reading where a collapsed soft line will cause a lock up. I don't see that as being my issue. The soft line didn't cause the hard line to fail. Brakes were fine all around before I replaced that hard line. Bleeding brakes is a science, it's not rocket science. I don't mind replacing the soft lines. When that doesn't resolve the issue...what's next? There appear to be blenders at the master cylinder. Is it possible I have an air lock somewhere. Is there a bleeding procedure or step I am missing. It is to the point of being ridiculous.
Any help is always appreciated!

Locking brakes can be caliper sticking. I would also replace the soft lines if it was me. There could be some trash in the line from the deterioration of hard lines. Also may be trash in caliper. May disassemble and clean or replace. They are not expensive.

I'm not overly concerned with the expense as much as I am the time. Reality is if I am going to do soft lines and pull the calipers...I might as well rebuild the whole mess and do rotors and pads. The brakes were fine. That hard line was going to pop. It is why we were poking around in the first place. I am just perplexed that replacing that one hard line is now turned into a puzzle. I am hoping that someone sees this thread and has a " I've been there" moment.

If you replace soft lines and/or calipers on one side, I'd recommend doing them on the other side also. I've been there as far as replacing one thing in a system, and then having to replace everything else. I put on a new radiator. Soon after, the thermostat gasket started leaking. Fixed that, and the heater core started leaking. Makes sense, I guess, since the cooling system is under pressure. Like GD said, bleeding the brakes probably pushed something in the old brake fluid and lines somewhere it didn't need to be.

I have owned over 40 vehicles (currently 8) and have done brakes on many of them. Any point of failure can cause another issue. Change it or don't....your choice. Trying to figure out the why sometimes has little impact. Trash from a corroded line creates a lot of potential problems. I had one that I had to replace nearly every hard line to eliminate the trash, so I did them all to be sure. Brakes are important. I replace anything suspect myself.

One of them holds 100 gallons.....I can't afford to fill them all at once. Two are inoperable until I rebuild them. I have a HUGE backyard with a couple carports in the back, No yard sale. Still negotiating on puprchasing a 52 Chevy 5 window truck....
But just keeping gas in the two daily drivers is about $400 a month.
