| It ain't the brake caliper, but why is pressure not releasing? (Page 1/1) |

The left front caliper of this truck was sticking so it was replaced. The new one occassionally sticks too, to the point of binding. So I bled the fluid off at the bleeder screw when it happened to get it home. It will still stick but usually releases.
What would you look.at first?

I would replace the soft line first.

Yep the rubber brake line.
Ive had a few old cars that needed the rubber line replaced long before the caliper itself had issues.[This message has been edited by 2.5 (edited 09-01-2021).]

If its only one side and releasing the fluid unbinds the caliper then its probably the soft line, I would start there. But never assume that a new/reconditioned part is good.
You could also check the brake proportioning valve and see if there is a separate port for each front caliper, it could be stuck/dirty.

Not a Dodge, but I'm hoping for the easy button query a brake line.

Sounds like the rubber brake line. What you described happened to my 1995 Chevy Silverado. Something about the inner ply acting as a one way check valve when it fails.

Hose "collapse" can be rotten hose or rust on support bracket in the middle.
If bracket is rusty, temp fix is carefully pry it open a little. If helps still need new line.
Does it has "True" ABS?
If problem isn't hose "collapse," can be the ABS "box." You likely need FSM before mess w/ that. Even then most can't be fixed.
Many trucks/vans have "Fake" ABS that just have extra "prop valve" for rear axle often w/ an easy to see link between frame and axle to see when truck is empty full or in between. (Some "hind" them and valve is next to 1 spring mount.)
That has problem too but often affect both rear wheels when only have 1 in and 1 out line for the valve.------------------
