I have a 92' Jeep Cherokee Laredo with the 4.0L in-line 6cyl RWD. The front left (drivers side) brake is clamping sown and not releasing unless I get down and bleed some fluid. I have just replaced the master cylinder, both calipers and the hoses going from the line to the caliper. I don't know what else to do. Do I need to just bleed it more to check for debris or is there something else?

Have you check to see if the slides have grooves worn in.

If you have bad grooves, here is a guide on how to fix..

Ill pull the calipers off and see if they need grinding down or replacement. Thank you!

Note from DJ
Are the bleeders on the top of the calipers; if not you put them on the wrong sides?

Was this issue there both before and after the parts replacements?

Bearkhan

The calipers are installed correctly with the bleeders on top and have had a thorough flush to get all the air out. But, yes, the problem has been here before and after the replacement of the parts.

I wonder if there is some crud in the metal line between that sticking caliper and the master.

old brake lines swell shut internally and do let pressure release.
Quick check, pump it up, let off, get out and crack the bleeder, if it squirts,
replace the rubber brake like.
Replaced many of them on all makes for the same reason.

Did you acquire the Jeep with this problem?
Or did it just start happening after you had the Jeep for a while.
