Brakes stickin after brake job

when we buy a total tu-- project, we figure we NEED to replace everything in the brake system, right>if disc car, maybe it has usuable rotors?? so when we buy a "driver" from someone, unless he replaced all the lines and MC, we need to do at least that part.,,, inspecting the rest of the system would give clue if more is needed. suspect wheel cyclinders, rebuild or replace for sure..... stopping can be so important!?????

like RRR said, brakes are the most basic of repairs for someone to learn to do themselves. I understand not everyone has a garage or needed tools, but...... basic tools are brakes are cheap, find a shade tree!!?? LOL
I Canada, build an igloo! LOL
