    My 99 2500 Sierra beater truck has a sticking front brake? Slide pins seem to slide freely but could maybe use some lubes and the fluid just dribbles out of the bleeder valve. I'm not sure what to check next. Can someone please help?

    "Fluid just dribbles out of the bleeder valve?" o_O Sounds like you haven't flushed and filled the brake system in a LOOOOONG time.

    You could try flushing as a starting point to get all the gunk out of the lines. In fact, it may make sense to disconnect each brake line at each caliper/cylinder and VERY GENTLY flush all the existing fluid out with fresh fluid. You need someone to watch the master cylinder reservoir and pour fluid in as you pump it out. This will probably take a couple of quarts of fluid. As you flush each line and start getting clean fluid, reconnect to the caliper/cylinder, then flush clean fluid through the caliper until it's clean. Start RR, then LR, then RF, then LF.

    Unfortunately, the calipers/cylinders are at the end of the line. Whatever gunk is causing the dribbling is in the caliper already. You could be looking at replacing the caliper if crud is keeping the piston from moving freely.

    I had all 4 brakes serviced by a shop probably 5 years ago but cant remember if they changed the fluid. I started watching some videos on youtube but didn't see my type of caliper so I stopped watching. I thought that if the fluid was gushing out that meant the line was bad? I was hoping this would be a simple job I could do but it's sounding like I will have to take it to a shop. Just wish I could find a video of my type of caliper being worked on. I don't even know how to remove it.

    Sounds like a stuck piston.

    Remove caliper, loosen bleeder screw, attempt to collapse the piston. If it’s difficult, replace caliper.

    Thats what i was thinking but im not sure how to remove this caliper. It seems to be locked in a dovetail type of steel frame...like if i remove the slide pins that does not help remove the caliper from the rotor. Hope that makes sense? I was just trying to be a cheap ass and not pay a shop to do it. lol

    Had a stuck brake-stuck-- slide pins on my old tacoma once but a buddy helped me fix it and was drinking beers so dont remember too well.

    My specialty is woodworking but I like to do my vehicle repair if it's easy enough. :D

    Be glad it’s not a 86 or older assembly. You will cuss your mother on those.

    So i need to find out if its the wheel bearings stuck or the caliper piston that is stuck... I will try tomorrow. Thanks for posting those videos. If i do have to take it to a shop i at least like to know for sure what is wrong first so i can make sure they dont lie to me.

    Im thinking bad brake hose. The inside can fail even if it looks ok on the outside. If fluid is barely coming out of the bleed. That usually means it’s not even making it there. The brakes should still be able to be bled even with a stuck piston.

    A collapsed brake hose can cause a dragging brake pad.

    I agree that you're making the right decision taking it to a professional. "A man has to know his limitations". If you have dribbling fluid out of the bleeder, and haven't had any brake work or maintenance done in five years, I suspect the news is not going to be good.
