I have a 08 silverada that has a right rear brake that sticks on a random basis. I have replaced the rotor ,caliper and flex line with no success.
Even after all this it is still sticking. Once the brake pedal gets harder I crawl under and release the bleed valve and all is good for a while.
when I release the bleed valve there is no strong out put of fluid , once a slight dribble.
Since there is one line coming to a coupling at the rear where it branches to to right and left wheel, and since the left wheel is fine I think the problem has got to be on the right side but I do not know where
Any help is appreciated
