It only has a slight jolt to the right when brakes first applied, then feels nice and even, does not continue to pull.
Tried posting in the “brakes” forum topic, system wouldn’t let me.

Recommend to replace both.

Sometimes they breakdown internally and retain fluid pressure, which may act as a preload of sorts.

If those slide pins have even the slightest bent in any of them replace them as a set.
**Edited to remove lady calipers.... I'm sure they'd hang up on something too!

I stood on my '73 so hard one time the right rotor locked up, I mean locked.
I changed out the rotor and it turned out to the hose.

The breakdown can happen internally.

Yes, internal breakdown is correct. In other words, the inside swells restricting fluid flow to caliper. Therefore, applying more pressure to the other side. External inspection will not reveal this. The pulling to one side or the other will. If it pulls right, left hose is bad. If it pulls left, right hose is bad. If you only replace one, you could have pulling in the opposite side that you could not tell previously because of the defective hose.
I have had this happen 2 times on 2 different trucks.
Replace both at same time.

- both wheels spin free
- I had someone gently apply brakes and I could not turn either wheel.
- no uneven wear on previous pads at all
I guess it must be a hose then....

Make sure you don't have the caliper flipped around and the hose piggy tailed. If the calipers move freely, wheel bearings and front end is tight, then you have a restriction. Most likely hoses.No kink or “hose twist”, but perhaps some “gunk” got in where the banjo bolt (if that’s the right name) goes when I was cleaning and wiping them down. I am going to replace both hoses.
On another note; I had nearly a 1/8” thick of “gunk” under the entire front end, when I noticed doing these brakes. I had to scrape it off with a putty knife. I am going to soak the entire front end , frame and engine bay in engine degreaser and head to the hot steam power wash.
No more fluid film, wd-40, oil, or any sticky petroleum substance. I’m quitting that stuff. So,,,does anyone know of a good metal coating rust preventative that won’t build up and get grimy gritty and gunky? I don’t even know why I bother, this truck hasn’t even seen water since we finished it’s nearly frame off restoration.

Take an air hose and blow through each hose from both ends, see if there is blockage.
Please report findings if any ;D
