97 Monty Sport 4x4 3.0 with 116k miles
Im experiencing an issue where after driving about 10-15 mins, the brakes start to drag, getting progressively worse, yesterday I had to pull over they were dragging so bad the rotors where getting hot. Ive heard where the caliper hoses (rubber lines) can collapse internally. I stopped driving it today because I afraid of warping the rotors.
Any help on this issue is greatly appreciated, thank you

Is it both sides?
Are the rear brakes dragging too?
If it's just one caliper, it's been my experience that one of the pistons or slide pins usually gets hung up. The slide pins can be cleaned up and lubed. The pins are pretty easy to access. I've never had much luck with my caliper piston repair skills. For a hung piston, I usually had to purchase a rebuilt caliper.

It seems like its all four,... or at least I KNOW its both fronts. During the first 10-15 minutes of driving the pedal starts of normal, but then the pedal gets higher and higher till the brakes start to drag. bizzare

I had similar experience with my rear disc last summer, driver side was hanging bad. I pulled the rear wheels check the calipers and the driver side wasn't fully retracting then when braking it didn't release like they should. Brake pedal was also decreasing in travel. I replaced both rear calipers, pads and rotors and that took care of any issues with the rears hanging up.Piston in caliper was the culprit.

I would start with cleaning and lubing the pins. Common first place to start before ripping down and replacing other brake components. Had a grand prix that had that issue and the pins would often get seized up. I was 16 and didn't know much better on the maintenance. I would start there.
