My 200 S10 shakes uncontrollably at times when braking. on 2000 Chevrolet S10

I had the front wheels off and it seems the caliper is not completely disengaged. Will cleaning the caliper pins solve this? Do I need to replace the pads and rotor at the same time? Thanks

There are several reasons the caliper may not release completely.Hose restriction , slide-pins(as you mentioned) , worn bracket , sludge build-up in caliper piston area , causing the piston to bind. The vibration is most likely due to an over-heated & warped rotor , which should be replaced with pads (both sides rec.) FIND CAUSE of problem first, before repair.
