I have a 2001 silverado Z-71 4x4 ext. cab with mostly 110,000 highway miles. When sitting at a stop light, drive thru, ect. my brakes will not release all the way. I have replaced front brake lines, calipers, rotors, fluid and pads and is no better. Any suggestions? I'm not getting any answers from local mechanics or dealerships only shoulder shrugs. Please help.

 

Still looking for help. I have now pulled the ABS fuses under the hood and left dash side. The ABS light stays lit on the instromet panel (of course). Is it ok to drive like this? Seems to have helped the problem so far, but have not driven alot as of yet.

 

Check the rear calipers. The rear pistons are plastic and become deformed and will not release completely.

 

master cylinder

 

when was the last time the brake lines were all bleed when i got my 01 1500 the rear calipers were seized i had to use a rubber mallet to get them off i replaced them and i had to bleed them three time to get it just right

 

I have put the ABS fuses back. I replaced the master cylinder this week along with the fluid resevoir and new brake fluid. Bench bled the master, bled at the master and all four calipers. Hopefully this takes care of the problem. Also, most of the sticking seems to be at the front wheels on the truck. Will be checking rear calipers soon. Thanks and keep the suggestions coming

 

new master cylinder seems to have solved the problem. Now to deal with the passlock system.
