My 93 blazer front drivers side brake will not release, replaced calipers, same problem. passenger side ok. thanks for help. phil

Open bleeder and see what happens.
Crack brake line before it goes into rubber flex hose
Check sliding pins and caliper mounting stuff.
Post back what happens.

hose collapsed on that side or caliper is frozen

hose inernal collapse is more common than percieved and wil cause this exact issue

check for that first

you will not be able to tell from the outside if it is collapsed


i have had a few like this over the years

86 pickup, 79 van, etc
